MySQL Performance Monitor with DRBD monitoring capabilities

The FromDual Performance Monitor for MySQL has now a new module for monitoring DRBD. Since more an more of our customers want to run MySQL High Availability solutions based on DRBD we have implemented this module.

We gather all information which are reported with the command:

# cat /proc/drbd

version: 8.3.8 (api:88/proto:86-94)
 0: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate C r----
    ns:1241240 nr:14311680 dw:15033532 dr:1241281 al:198 bm:52 lo:0 pe:0 ua:0
    ap:0 ep:1 wo:b oos:0

Now you can easily find the DRBD version which is installed on your systems, the connection state, the role, the disk state and the used protocol of your DRBD device.

Further we have added graphs for network and disk traffic and for internal data structure activity.

When DRBD is down we will rise an alert:

The new DRBD module is included in the Version v0.6 of our MySQL Performance Monitoring which is planned to be released next week. The FromDual Performance Monitor for MySQL is based on Zabbix.

If you have any suggestions how to improve the DRBD module or our monitoring solution at all please let us know.
