uwsgi-dogstatsd

uWSGI plugin to emit DogStatsD metrics to Datadog via the Datadog Agent

INSTALL

The plugin is 2.x friendly, so installation can be done directly from the repo:

uwsgi --build-plugin https://github.com/Datadog/uwsgi-dogstatsd

If you are packaging the plugin for distribution, please read the uWSGI Guide for Packagers on plugin placement and extra directives like plugin_dir.

USAGE

Depends on a Datadog Agent to be installed and by default listens for dogstatsd on port 8125.

Configure your .ini file to enable the metrics subsystem, and enable the dogstatsd plugin.

Here's a

[uwsgi]
master = true
processes = 8
threads = 4

http = :9090

# DogStatsD plugin configuration
enable-metrics = true
plugin = dogstatsd
stats-push = dogstatsd:127.0.0.1:8125,myapp

# Application to load
wsgi-file = app.py
...

You can also add additional tags or filter which metrics are published (or how they are published) using one or more optional configuration options:

stats-push = dogstatsd:127.0.0.1:8125,myapp
dogstatsd-extra-tags = app:foo_service,instance:1
dogstatsd-no-workers = true
dogstatsd-all-gauges = true
dogstatsd-whitelist-metric = core.busy_workers
dogstatsd-whitelist-metric = core.idle_workers
dogstatsd-whitelist-metric = core.overloaded
dogstatsd-whitelist-metric = socket.listen_queue

This will begin producing metrics with the prefix defined in the configuration, myapp here:

myapp.core.avg_response_time
myapp.core.busy_workers
myapp.core.idle_workers
myapp.core.overloaded
myapp.core.routed_signals
myapp.core.total_rss
myapp.core.total_tx
myapp.core.total_vsz
myapp.core.unrouted_signals
myapp.rss_size
myapp.socket.listen_queue
myapp.vsz_size
myapp.worker.avg_response_time
myapp.worker.core.exceptions
myapp.worker.core.offloaded_requests
myapp.worker.core.read_errors
myapp.worker.core.requests
myapp.worker.core.routed_requests
myapp.worker.core.static_requests
myapp.worker.core.write_errors
myapp.worker.delta_requests
myapp.worker.failed_requests
myapp.worker.requests
myapp.worker.respawns
myapp.worker.rss_size
myapp.worker.total_tx
myapp.worker.vsz_size

The metrics are tagged and split where there are more than one occurrence, such as CPU core, worker.
