## Run pprof via a web interface
If the `-http` flag is specified, pprof starts a web server at
the specified host:port that provides an interactive web-based interface to pprof.
Host is optional, and is "localhost" by default. Port is optional, and is a
random available port by default. `-http=":"` starts a server locally at
a random port.
```
pprof -http=[host]:[port] [main_binary] profile.pb.gz
```
The preceding command should automatically open your web browser at
the right page; if not, you can manually visit the specified port in
your web browser.

# General usage # Usage Modes
There are few different ways of using `pprof`.
## Report generation
If a report format is requested on the command line:
pprof <format> [options] source
pprof will generate a report in the specified format and exit.
Formats can be either text, or graphical. See below for details about
supported formats, options, and sources.
## Interactive terminal use
Without a format specifier:
pprof [options] source
pprof will start an interactive shell in which the user can type
commands. Type `help` to get online help.
## Web interface
If a host:port is specified on the command line:
pprof -http=[host]:[port] [options] source
pprof will start serving HTTP requests on the specified port. Visit
the HTTP url corresponding to the port (typically `http://<host>:<port>/`)
in a browser to see the interface.

## Tag filtering
Samples in a profile may have tags. These tags have a name and a value; this
value can be either numeric or a string. pprof can select samples from a
profile based on these tags using the `-tagfocus` and `-tagignore` options.
Generally, these options work as follows:
* **-tagfocus=_regex_** or **-tagfocus=_range_:** Restrict to samples with tags
matched by regexp or in range.
* **-tagignore=_regex_** or **-tagignore=_range_:** Discard samples with tags
matched by regexp or in range.
When using `-tagfocus=regex` and `-tagignore=regex`, the regex will be compared
to each value associated with each tag. If one specifies a value
like `regex1,regex2`, then only samples with a tag value matching `regex1`
and a tag value matching `regex2` will be kept.
In addition to being able to filter on tag values, one can specify the name of
the tag which a certain value must be associated with using the notation
`-tagfocus=tagName=value`. Here, the `tagName` must match the tag's name
exactly, and the value can be either a regex or a range. If one specifies
a value like `regex1,regex2`, then samples with a tag value (paired with the
specified tag name) matching either `regex1` or matching `regex2` will match.
Here are examples explaining how `tagfocus` can be used:
* `-tagfocus 128kb:512kb` accepts a sample iff it has any numeric tag with
memory value in the specified range.
* `-tagfocus mytag=128kb:512kb` accepts a sample iff it has a numeric tag
`mytag` with memory value in the specified range. There isn't a way to say
`-tagfocus mytag=128kb:512kb,16kb:32kb`
or `-tagfocus mytag=128kb:512kb,mytag2=128kb:512kb`. Just single value or
range for numeric tags.
* `-tagfocus someregex` accepts a sample iff it has any string tag with
`tagName:tagValue` string matching specified regexp. In the future, this
will change to accept sample iff it has any string tag with `tagValue` string
matching specified regexp.
* `-tagfocus mytag=myvalue1,myvalue2` matches if either of the two tag values
are present.
`-tagignore` works similarly, except that it discards matching samples, instead
of keeping them.
If both the `-tagignore` and `-tagfocus` expressions (either a regexp or a
range) match a given sample, then the sample will be discarded.
