+

+
+---
+
+The housekeeping function runs [`git gc`][man] on the current project Git
+repository.
+
+`git gc` runs a number of housekeeping tasks, such as compressing file
+revisions (to reduce disk space and increase performance) and removing
+unreachable objects which may have been created from prior invocations of
+`git add`.
+
+You can find this option under your **[Project] > Settings**.

+# How to restart GitLab
+
+Depending on how you installed GitLab, there are different methods to restart
+its service(s).
+
+If you want the TL;DR versions, jump to:
+
+- [Omnibus GitLab restart](#omnibus-gitlab-restart)
+- [Omnibus GitLab reconfigure](#omnibus-gitlab-reconfigure)
+- [Source installation restart](#installations-from-source)
+
+## Omnibus installations
+
+If you have used the [Omnibus packages][omnibus-dl] to install GitLab, then
+you should already have `gitlab-ctl` in your `PATH`.
+
+`gitlab-ctl` interacts with the Omnibus packages and can be used to restart the
+GitLab Rails application (Unicorn) as well as the other components, like:
+
+- GitLab Workhorse
+- Sidekiq
+- PostgreSQL (if you are using the bundled one)
+- NGINX (if you are using the bundled one)
+- Redis (if you are using the bundled one)
+- [Mailroom][]
+- Logrotate
+
+### Omnibus GitLab restart
+
+There may be times in the documentation where you will be asked to _restart_
+GitLab. In that case, you need to run the following command:
+
+```bash
+sudo gitlab-ctl restart
+```
+
+The output should be similar to this:
+
+```
+ok: run: gitlab-workhorse: (pid 11291) 1s
+ok: run: logrotate: (pid 11299) 0s
+ok: run: mailroom: (pid 11306) 0s
+ok: run: nginx: (pid 11309) 0s
+ok: run: postgresql: (pid 11316) 1s
+ok: run: redis: (pid 11325) 0s
+ok: run: sidekiq: (pid 11331) 1s
+ok: run: unicorn: (pid 11338) 0s
+```
+
+To restart a component separately, you can append its service name to the
+`restart` command. For example, to restart **only** NGINX you would run:
+
+```bash
+sudo gitlab-ctl restart nginx
+```
+
+To check the status of GitLab services, run:
+
+```bash
+sudo gitlab-ctl status
+```
+
+Notice that all services say `ok: run`.
+
+Sometimes, components time out during the restart and sometimes they get stuck.
+In that case, you can use `gitlab-ctl kill <service>` to send the `SIGKILL`
+signal to the service, for example `sidekiq`. After that, a restart should
+perform fine.
+
+As a last resort, you can try to
+[reconfigure GitLab](#omnibus-gitlab-reconfigure) instead.
+
+### Omnibus GitLab reconfigure
+
+There may be times in the documentation where you will be asked to _reconfigure_
+GitLab. Remember that this method applies only for the Omnibus packages.
+
+Reconfigure Omnibus GitLab with:
+
+```bash
+sudo gitlab-ctl reconfigure
+```
+
+Reconfiguring GitLab should occur in the event that something in its
+configuration (`/etc/gitlab/gitlab.rb`) has changed.
+
+When you run this command, [Chef], the underlying configuration management
+application that powers Omnibus GitLab, will make sure that all directories,
+permissions, services, etc., are in place and in the same shape that they were
+initially shipped.
+
+It will also restart GitLab components where needed, if any of their
+configuration files have changed.
+
+If you manually edit any files in `/var/opt/gitlab` that are managed by Chef,
+running reconfigure will revert the changes AND restart the services that
+depend on those files.
+
+## Installations from source
+
+If you have followed the official installation guide to [install GitLab from
+source][install], run the following command to restart GitLab:
+
+```
+sudo service gitlab restart
+```
+
+The output should be similar to this:
+
+```
+Shutting down GitLab Unicorn
+Shutting down GitLab Sidekiq
+Shutting down GitLab Workhorse
+Shutting down GitLab MailRoom
+...
+GitLab is not running.
+Starting GitLab Unicorn
+Starting GitLab Sidekiq
+Starting GitLab Workhorse
+Starting GitLab MailRoom
+...
+The GitLab Unicorn web server with pid 28059 is running.
+The GitLab Sidekiq job dispatcher with pid 28176 is running.
+The GitLab Workhorse with pid 28122 is running.
+The GitLab MailRoom email processor with pid 28114 is running.
+GitLab and all its components are up and running.
+```
+
+This should restart Unicorn, Sidekiq, GitLab Workhorse and [Mailroom][]
+(if enabled). The init service file that does all the magic can be found on
+your server in `/etc/init.d/gitlab`.
+
+---
+
+If you are using other init systems, like systemd, you can check the
+[GitLab Recipes][gl-recipes] repository for some unofficial services. These are
+**not** officially supported so use them at your own risk.

+# Introduction to build artifacts
+
+Artifacts is a list of files and directories which are attached to a build
+after it completes successfully.
+
+Since GitLab 8.2 and [GitLab Runner] 0.7.0, build artifacts that are created by
+GitLab Runner are uploaded to GitLab and are downloadable as a single archive
+(`tar.gz`) using the GitLab UI.
+
+Starting from GitLab 8.4 and GitLab Runner 1.0, the artifacts archive format
+changed to `ZIP`, and it is now possible to browse its contents, with the added
+ability of downloading the files separately.
+
+## Enabling build artifacts
+
+_If you are searching for ways to use artifacts, jump to
+[Defining artifacts in `.gitlab-ci.yml`](#defining-artifacts-in-gitlab-ciyml)._
+
+The artifacts feature is enabled by default in all GitLab installations.
+To disable it site-wide, follow the steps below.
+
+---
+
+**In Omnibus installations:**
+
+1. Edit `/etc/gitlab/gitlab.rb` and add the following line:
+
+    ```ruby
+    gitlab_rails['artifacts_enabled'] = false
+    ```
+
+1. Save the file and [reconfigure GitLab][] for the changes to take effect.
+
+---
+
+**In installations from source:**
+
+1. Edit `/home/git/gitlab/config/gitlab.yml` and add or amend the following lines:
+
+    ```yaml
+    artifacts:
+      enabled: false
+    ```
+
+1. Save the file and [restart GitLab][] for the changes to take effect.
+
+## Defining artifacts in `.gitlab-ci.yml`
+
+A simple example of using the artifacts definition in `.gitlab-ci.yml` would be
+the following:
+
+```yaml
+pdf:
+  script: xelatex mycv.tex
+  artifacts:
+    paths:
+    - mycv.pdf
+```
+
+A job named `pdf` calls the `xelatex` command in order to build a pdf file from
+the latex source file `mycv.tex`. We then define the `artifacts` paths which in
+turn are defined with the `paths` keyword. All paths to files and directories
+are relative to the repository that was cloned during the build.
+
+For more examples on artifacts, follow the
+[separate artifacts yaml documentation](../yaml/README.md#artifacts).
+
+## Storing build artifacts
+
+After a successful build, GitLab Runner uploads an archive containing the build
+artifacts to GitLab.
+
+To change the location where the artifacts are stored, follow the steps below.
+
+---
+
+**In Omnibus installations:**
+
+_The artifacts are stored by default in
+`/var/opt/gitlab/gitlab-rails/shared/artifacts`._
+
+1. To change the storage path for example to `/mnt/storage/artifacts`, edit
+   `/etc/gitlab/gitlab.rb` and add the following line:
+
+    ```ruby
+    gitlab_rails['artifacts_path'] = "/mnt/storage/artifacts"
+    ```
+
+1. Save the file and [reconfigure GitLab][] for the changes to take effect.
+
+---
+
+**In installations from source:**
+
+_The artifacts are stored by default in
+`/home/git/gitlab/shared/artifacts`._
+
+1. To change the storage path for example to `/mnt/storage/artifacts`, edit
+   `/home/git/gitlab/config/gitlab.yml` and add or amend the following lines:
+
+    ```yaml
+    artifacts:
+      enabled: true
+      path: /mnt/storage/artifacts
+    ```
+
+1. Save the file and [restart GitLab][] for the changes to take effect.
+
+## Browsing build artifacts
+
+When GitLab receives an artifacts archive, an archive metadata file is also
+generated. This metadata file describes all the entries that are located in the
+artifacts archive itself. The metadata file is in a binary format, with
+additional GZIP compression.
+
+GitLab does not extract the artifacts archive in order to save space, memory
+and disk I/O. It instead inspects the metadata file which contains all the
+relevant information. This is especially important when there is a lot of
+artifacts, or an archive is a very large file.
+
+---
+
+After a successful build, if you visit the build's specific page, you can see
+that there are two buttons.
+
+One is for downloading the artifacts archive and the other for browsing its
+contents.
+
+![Build artifacts browser button](img/build_artifacts_browser_button.png)
+
+---
+
+The archive browser shows the name and the actual file size of each file in the
+archive. If your artifacts contained directories, then you are also able to
+browse inside them.
+
+Below you can see an image of three different file formats, as well as two
+directories.
+
+![Build artifacts browser](img/build_artifacts_browser.png)
+
+---
+
+## Downloading build artifacts
+
+If you need to download the whole archive, there are buttons in various places
+inside GitLab that make that possible.
+
+1. While on the builds page, you can see the download icon for each build's
+   artifacts archive in the right corner
+
+1. While inside a specific build, you are presented with a download button
+   along with the one that browses the archive
+
+1. And finally, when browsing and archive you can see the download button at
+   the top right corner
+
+---
+
+Note that GitLab does not extract the entire artifacts archive to send just a
+single file to the user.
+
+When clicking on a specific file, [GitLab Workhorse] extracts it from the
+archive and the download begins.
+
+This implementation saves space, memory and disk I/O.

+# InfluxDB Configuration
+
+The default settings provided by [InfluxDB] are not sufficient for a high traffic
+GitLab environment. The settings discussed in this document are based on the
+settings GitLab uses for GitLab.com, depending on your own needs you may need to
+further adjust them.
+
+If you are intending to run InfluxDB on the same server as GitLab, make sure
+you have plenty of RAM since InfluxDB can use quite a bit depending on traffic.
+
+Unless you are going with a budget setup, it's advised to run it separately.
+
+## Requirements
+
+- InfluxDB 0.9.5 or newer
+- A fairly modern version of Linux
+- At least 4GB of RAM
+- At least 10GB of storage for InfluxDB data
+
+Note that the RAM and storage requirements can differ greatly depending on the
+amount of data received/stored. To limit the amount of stored data users can
+look into [InfluxDB Retention Policies][influxdb-retention].
+
+## Installation
+
+Installing InfluxDB is out of the scope of this document. Please refer to the
+[InfluxDB documentation].
+
+## InfluxDB Server Settings
+
+Since InfluxDB has many settings that users may wish to customize themselves
+(e.g. what port to run InfluxDB on), we'll only cover the essentials.
+
+The configuration file in question is usually located at
+`/etc/influxdb/influxdb.conf`. Whenever you make a change in this file,
+InfluxDB needs to be restarted.
+
+### Storage Engine
+
+InfluxDB comes with different storage engines and as of InfluxDB 0.9.5 a new
+storage engine is available, called [TSM Tree]. All users **must** use the new
+`tsm1` storage engine as this [will be the default engine][tsm1-commit] in
+upcoming InfluxDB releases.
+
+Make sure you have the following in your configuration file:
+
+```
+[data]
+  dir = "/var/lib/influxdb/data"
+  engine = "tsm1"
+```
+
+### Admin Panel
+
+Production environments should have the InfluxDB admin panel **disabled**. This
+feature can be disabled by adding the following to your InfluxDB configuration
+file:
+
+```
+[admin]
+  enabled = false
+```
+
+### HTTP
+
+HTTP is required when using the [InfluxDB CLI] or other tools such as Grafana,
+thus it should be enabled. When enabling make sure to _also_ enable
+authentication:
+
+```
+[http]
+  enabled = true
+  auth-enabled = true
+```
+
+_**Note:** Before you enable authentication, you might want to [create an
+admin user](#create-a-new-admin-user)._
+
+### UDP
+
+GitLab writes data to InfluxDB via UDP and thus this must be enabled. Enabling
+UDP can be done using the following settings:
+
+```
+[[udp]]
+  enabled = true
+  bind-address = ":8089"
+  database = "gitlab"
+  batch-size = 1000
+  batch-pending = 5
+  batch-timeout = "1s"
+  read-buffer = 209715200
+```
+
+This does the following:
+
+1. Enable UDP and bind it to port 8089 for all addresses.
+2. Store any data received in the "gitlab" database.
+3. Define a batch of points to be 1000 points in size and allow a maximum of
+   5 batches _or_ flush them automatically after 1 second.
+4. Define a UDP read buffer size of 200 MB.
+
+One of the most important settings here is the UDP read buffer size as if this
+value is set too low, packets will be dropped. You must also make sure the OS
+buffer size is set to the same value, the default value is almost never enough.
+
+To set the OS buffer size to 200 MB, on Linux you can run the following command:
+
+```bash
+sysctl -w net.core.rmem_max=209715200
+```
+
+To make this permanent, add the following to `/etc/sysctl.conf` and restart the
+server:
+
+```bash
+net.core.rmem_max=209715200
+```
+
+It is **very important** to make sure the buffer sizes are large enough to
+handle all data sent to InfluxDB as otherwise you _will_ lose data. The above
+buffer sizes are based on the traffic for GitLab.com. Depending on the amount of
+traffic, users may be able to use a smaller buffer size, but we highly recommend
+using _at least_ 100 MB.
+
+When enabling UDP, users should take care to not expose the port to the public,
+as doing so will allow anybody to write data into your InfluxDB database (as
+[InfluxDB's UDP protocol][udp] doesn't support authentication). We recommend either
+whitelisting the allowed IP addresses/ranges, or setting up a VLAN and only
+allowing traffic from members of said VLAN.
+
+## Create a new admin user
+
+If you want to [enable authentication](#http), you might want to [create an
+admin user][influx-admin]:
+
+```
+influx -execute "CREATE USER jeff WITH PASSWORD '1234' WITH ALL PRIVILEGES"
+```
+
+## Create the `gitlab` database
+
+Once you get InfluxDB up and running, you need to create a database for GitLab.
+Make sure you have changed the [storage engine](#storage-engine) to `tsm1`
+before creating a database.
+
+_**Note:** If you [created an admin user](#create-a-new-admin-user) and enabled
+[HTTP authentication](#http), remember to append the username (`-username <username>`)
+and password (`-password <password>`)  you set earlier to the commands below._
+
+Run the following command to create a database named `gitlab`:
+
+```bash
+influx -execute 'CREATE DATABASE gitlab'
+```
+
+The name **must** be `gitlab`, do not use any other name.
+
+Next, make sure that the database was successfully created:
+
+```bash
+influx -execute 'SHOW DATABASES'
+```
+
+The output should be similar to:
+
+```
+name: databases
+---------------
+name
+_internal
+gitlab
+```
+
+That's it! Now your GitLab instance should send data to InfluxDB.

+# InfluxDB Schema
+
+The following measurements are currently stored in InfluxDB:
+
+- `PROCESS_file_descriptors`
+- `PROCESS_gc_statistics`
+- `PROCESS_memory_usage`
+- `PROCESS_method_calls`
+- `PROCESS_object_counts`
+- `PROCESS_transactions`
+- `PROCESS_views`
+
+Here, `PROCESS` is replaced with either `rails` or `sidekiq` depending on the
+process type. In all series, any form of duration is stored in milliseconds.
+
+## PROCESS_file_descriptors
+
+This measurement contains the number of open file descriptors over time. The
+value field `value` contains the number of descriptors.
+
+## PROCESS_gc_statistics
+
+This measurement contains Ruby garbage collection statistics such as the amount
+of minor/major GC runs (relative to the last sampling interval), the time spent
+in garbage collection cycles, and all fields/values returned by `GC.stat`.
+
+## PROCESS_memory_usage
+
+This measurement contains the process' memory usage (in bytes) over time. The
+value field `value` contains the number of bytes.
+
+## PROCESS_method_calls
+
+This measurement contains the methods called during a transaction along with
+their duration, and a name of the transaction action that invoked the method (if
+available). The method call duration is stored in the value field `duration`,
+while the method name is stored in the tag `method`. The tag `action` contains
+the full name of the transaction action. Both the `method` and `action` fields
+are in the following format:
+
+```
+ClassName#method_name
+```
+
+For example, a method called by the `show` method in the `UsersController` class
+would have `action` set to `UsersController#show`.
+
+## PROCESS_object_counts
+
+This measurement is used to store retained Ruby objects (per class) and the
+amount of retained objects. The number of objects is stored in the `count` value
+field while the class name is stored in the `type` tag.
+
+## PROCESS_transactions
+
+This measurement is used to store basic transaction details such as the time it
+took to complete a transaction, how much time was spent in SQL queries, etc. The
+following value fields are available:
+
+| Value | Description |
+| ----- | ----------- |
+| `duration`  | The total duration of the transaction |
+| `allocated_memory` | The amount of bytes allocated while the transaction was running. This value is only reliable when using single-threaded application servers |
+| `method_duration` | The total time spent in method calls |
+| `sql_duration` | The total time spent in SQL queries |
+| `view_duration` | The total time spent in views |
+
+## PROCESS_views
+
+This measurement is used to store view rendering timings for a transaction. The
+following value fields are available:
+
+| Value | Description |
+| ----- | ----------- |
+| `duration` | The rendering time of the view |
+| `view` | The path of the view, relative to the application's root directory |
+
+The `action` tag contains the action name of the transaction that rendered the
+view.

+# GitLab Performance Monitoring
+
+GitLab comes with its own application performance measuring system as of GitLab
+8.4, simply called "GitLab Performance Monitoring". GitLab Performance Monitoring is available in both the
+Community and Enterprise editions.
+
+Apart from this introduction, you are advised to read through the following
+documents in order to understand and properly configure GitLab Performance Monitoring:
+
+- [GitLab Configuration](gitlab_configuration.md)
+- [InfluxDB Configuration](influxdb_configuration.md)
+- [InfluxDB Schema](influxdb_schema.md)
+
+## Introduction to GitLab Performance Monitoring
+
+GitLab Performance Monitoring makes it possible to measure a wide variety of statistics
+including (but not limited to):
+
+- The time it took to complete a transaction (a web request or Sidekiq job).
+- The time spent in running SQL queries and rendering HAML views.
+- The time spent executing (instrumented) Ruby methods.
+- Ruby object allocations, and retained objects in particular.
+- System statistics such as the process' memory usage and open file descriptors.
+- Ruby garbage collection statistics.
+
+Metrics data is written to [InfluxDB][influxdb] over [UDP][influxdb-udp]. Stored
+data can be visualized using [Grafana][grafana] or any other application that
+supports reading data from InfluxDB. Alternatively data can be queried using the
+InfluxDB CLI.
+
+## Metric Types
+
+Two types of metrics are collected:
+
+1. Transaction specific metrics.
+1. Sampled metrics, collected at a certain interval in a separate thread.
+
+### Transaction Metrics
+
+Transaction metrics are metrics that can be associated with a single
+transaction. This includes statistics such as the transaction duration, timings
+of any executed SQL queries, time spent rendering HAML views, etc. These metrics
+are collected for every Rack request and Sidekiq job processed.
+
+### Sampled Metrics
+
+Sampled metrics are metrics that can't be associated with a single transaction.
+Examples include garbage collection statistics and retained Ruby objects. These
+metrics are collected at a regular interval. This interval is made up out of two
+parts:
+
+1. A user defined interval.
+1. A randomly generated offset added on top of the interval, the same offset
+   can't be used twice in a row.
+
+The actual interval can be anywhere between a half of the defined interval and a
+half above the interval. For example, for a user defined interval of 15 seconds
+the actual interval can be anywhere between 7.5 and 22.5. The interval is
+re-generated for every sampling run instead of being generated once and re-used
+for the duration of the process' lifetime.

+# File finder
+
+_**Note:** This feature was [introduced][gh-9889] in GitLab 8.4._
+
+---
+
+The file finder feature allows you to quickly shortcut your way when you are
+searching for a file in a repository using the GitLab UI.
+
+You can find the **Find File** button when in the **Files** section of a
+project.
+
+![Find file button](img/file_finder_find_button.png)
+
+---
+
+For those who prefer to keep their fingers on the keyboard, there is a
+[shortcut button](shortcuts.md) as well, which you can invoke from _anywhere_
+in a project.
+
+Press `t` to launch the File search function when in **Issues**,
+**Merge requests**, **Milestones**, even the project's settings.
+
+Start typing what you are searching for and watch the magic happen. With the
+up/down arrows, you go up and down the results, with `Esc` you close the search
+and go back to **Files**.
+
+## How it works
+
+The File finder feature is powered by the [Fuzzy filter] library.
+
+It implements a fuzzy search with highlight, and tries to provide intuitive
+results by recognizing patterns that people use while searching.
+
+For example, consider the [GitLab CE repository][ce] and that we want to open
+the `app/controllers/admin/deploy_keys_controller.rb` file.
+
+Using fuzzy search, we start by typing letters that get us closer to the file.
+
+**Protip:** To narrow down your search, include `/` in your search terms.
