CEPH-MIB DEFINITIONS ::= BEGIN IMPORTS MODULE-IDENTITY, NOTIFICATION-TYPE, enterprises FROM SNMPv2-SMI MODULE-COMPLIANCE, NOTIFICATION-GROUP FROM SNMPv2-CONF ; -- Linting information: -- -- # smilint -l 6 -i notification-not-reversible ./CEPH-MIB.txt -- -- ignore: notification-not-reversible since our SNMP gateway doesn't use SNMPv1 -- ceph MODULE-IDENTITY LAST-UPDATED "202111010000Z" -- Nov 01, 2021 ORGANIZATION "The Ceph Project https://ceph.io" CONTACT-INFO "Email: Send comments to: " 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 "
