Hi.
I have configured gerrit-trigger-plugin, Gerrit and events-log plugin. Rest_API is working, events-log plugin is also accessible (INFO: Gerrit Plugin events-log is installed) but there is no connection to events-log archive (checked also with Wireshark). In the LOG there is no "connectionEstablished" from GerritMissedEventsPlaybackManager. When I remove the events-log plugin there IS "connectionEstablished" from GerritMissedEventsPlaybackManager in the LOG reporting WARNING: Playback of missed events not supported for server dev.local - gerrit!

On server configuration page there is only warning about not supported "Project created events" which will be available in next release 2.12.
"Gerrit version is a bit old, so not all Gerrit features are enabled. The following features have been disabled: Project created events requires 2.12"
