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.
"
REVISION
"202111010000Z" --Nov 01, 2021
DESCRIPTION
"Latest version including the following updates;
- MIB restructure to align with linting
- names shortened and simplified (less verbose)
- Simplified structure due to switch to https://github.com/maxwo/snmp_notifier
- objects removed
- notifications updated
- Added module compliance
- Updated to latest prometheus alert rule definitions
