You can monitor the state of DRBD via SNMP by using net-snmp's snmpd 'extend' feature: Add this to /etc/snmp/snmpd.conf: extend drbd-value /usr/bin/drbd-status.sh The contents of /usr/bin/drbd-status.sh should be: #!/bin/sh for i in `/bin/cat /proc/drbd | grep "cs:" | awk '{print $2}' | awk -F: '{print $2}'` do if [ "$i" == "Connected" ]; then echo "1"; else echo "2"; fi done Then use the following SNMP OID to walk the resulting 'table': 1.3.6.1.4.1.8072.1.3.2.4.1.2.15.100.114.98.100.45.118.97.108.117.101 d r b d - v a l u e We then setup a 'threshold' in our monitoring system for when the values are not '1'. This technique could be extended to accomplish a lot more.
