DESCRIPTION
|
|
"The MIB module for Ceph. In it's current form it only
|
|
supports Notifications, since Ceph itself doesn't provide
|
|
any SNMP agent functionality.
|
|
|
|
Notifications are provided through a Prometheus/Alertmanager
|
|
webhook passing alerts to an external gateway service that is
|
|
responsible for formatting, forwarding and authenticating to
|
|
the SNMP receiver.
|

|
|
|
