Why is my agent process dying?

Best place to check are the logs in /var/log/datadog/. If you see something like:

2013-12-11 20:52:11,887 | ERROR | dd.dogstatsd | util(util.py:281) | Self-destructing...

It means an iteration of the agent took too long and its internal watchdog thread killed itself in order to prevent it from hanging. The max amount of time an iteration can take before the agent kills itself is (10 * the check frequency), which defaults to 15s for the collector process and the 10s for dogstatsd.

How often is data collected?

• Data from existing checks like mysql or nginx are collected every 15s via the collector process.
• Data submitted via statsd gets aggregated locally and flushed every 10s to Datadog via the dogstatsd process.
