Monitoring

Monitoring

ElasticInbox exposes following performance stats through JMX:

• LMTP
  • Delivery
    • success
    • defer
    • defer_failure
    • discard
    • reject_nonExistent
    • reject_overQuota
• POP3
  • Auth
    • success
    • fail
• Hector
  • Read
  • Write
• Jetty

It’s possible to enable/disable performance counters through config files. For LMTP, POP3 and Hector stats set enable_performance_counters to true in elasticinbox.yml. performance_counters_interval is an interval for accumulating stats, set it to your monitoring system’s interval (e.g. if munin collects every 3 minutes, set it to 3*60).

For Jetty, you need to set statOn=true in jetty.xml:

<Configure id="Server" class="org.eclipse.jetty.server.Server">
...
    <Call name="addConnector">
      <Arg>
          <New class="org.eclipse.jetty.server.nio.SelectChannelConnector">
          ...
          <Set name="statsOn">true</Set>
