StatsD WordPress Client

For live environment no-latency massively-scalable application metric tracking and code profiling via Etsy’s StatsD + Graphite.

Tracks everything in WordPress and Multisite:

• Logins (success, fails, logout)
• Password resets (attempts/successes)
• User count (guage)
• Users (registrations, spam, ham)
• Posting (publish, trash, delete)
• Commenting (received, approved, trashed, spam, unspam)
• Attachments (Add, edit, delete)
• XML-RPC (every command individually, you can rollup)
• Multisite blog count (guage)
• Multiiste blog actions (new, spam, ham, archive, unarchive, delete, undelete)
• Page generation times
• Query count (type + time when SAVEQUERIES defined)
• Remote HTTP requests (count, time – by host)
• WP Cron calls
• WP Emails
• and more!

Requires StatsD on localhost or a server on your private network.

You can also call the $statsd global class in other plugin/theme code for instant tracking of any application metric. See API usage instructions: https://github.com/domnikl/statsd-php/blob/develop/README.md

To Do

Want to implement batch collection and send of metrics via one or minimal UDP packets required based on connection time.

1. Install StatsD on localhost or a server on your private network.
2. If StatsD is not on localhost, define the local daemon IP in wp-config.php: define( 'STATSD_IP', 'x.x.x.x' );
3. Install the plugin
4. Activate or Network Activate on multisite
5. That’s it!

See the FAQ for more advanced configuration.

By default the parent namespace used for stats is “yourdomain_yourpath.wordpress.” where yourdomain_yourpath would be “www_domain_com_blog” if your site is http://www.domain.com/blog/. You can override the parent namespace via the define('STATSD_NAMESPACE', 'mysite.myserver'); define in wp-config.php. This one is very important, controls how it shows up in Graphite stats.
This should be segmented, left to right general to specific. All “.” trigger segments. For example:
applicationname.server like ‘wpmudev.app1’ or ‘edublogs.web4’. That allows for drilling down, but can still wrapup in graphs with ‘edublogs.‘ etc.

Can also be run as an mu-plugin by dropping statsd.php in /wp-content/mu-plugins/.

If needed you can overide the default UDP port of 8125 via define('STATSD_PORT', xxxx); define.

If you have a very high traffic site you can lower the default 0.5 sample rate for per-pageload calls via STATSD_SAMPLE_RATE.

If you don’t want to send HTTP metrics per page URL, you can disable this via SKIP_URL_METRICS
