#Eventmonitor Eventmonitor monitors diffrent event sources. These events are written to an InfluxDB and can be used by Grafana for annotations.

##InfluxDB schema Events are written to a measurement per provider. Currently there are two providers, auth and docker.

Shared tags:

• hostname: The host the event occured on. This is either provided through the -host command line flag or automatically retrieved from the operation system.
• event: The type of event.

Shared fields:

• description: A textual description of what happend.

###Auth log The Linux authentication log is monitored for PAM user login and logout messages. Authentication events are stored in the authEvents measurement. Event values therefore are login and logout.

Additional tags:

• user: The name of the user that caused the event.

###Docker Docker is monitored for events indicating the start and stop of a container. Docker events are stored in the dockerEvent measurement.. Event values are containerStart and containerStop.

Additional tags:

• container: The name of the container that caused the event.
• image: The image the container was running.
• service: The Docker Compose service the container belonged to, if available.

##Grafana Annotations ###Add annotations for logouts, regardless of the user that logged out.

SELECT description FROM events WHERE type='logout' AND $timeFilter

###Add annotations for logins and logouts of the root user.

SELECT description FROM events WHERE "user"='root' AND $timeFilter
