This plugin monitors Scality Ring Supervisor through SNMP.
|
||||
New checks added:
|
||||
Ring Disks: Monitors the number of disks per ring. Parameters can be set for warn/crit if the number of disks reported is below a value.
|
||||
|
||||
Ring Stage: Monitors the Ring Status. If the ring is not in Run State, service will be CRIT.
|
||||
|
||||
Ring Storage: Storage used per Ring. Parameters can be set and the general filesystem parameters are used.
|
||||
|
||||
Supervisor Status: Monitors the supervisor status and server status. If the supervisor is not available or any of the servers are not OK, the service goes CRIT.
|
||||
