Requested feedback given; Virtual meetings are never as good, and I really don't like this idea. In my experience, just as much productive decision making happens in the unofficial after-hours activities as during formal(ish) meetings/presentations. I think it is very important that the meeting remain in-person if at all possible.

[Linux-HA] Monitor a Pacemaker Cluster with ocf:pacemaker:ClusterMon and/or external-agent
I want to configure Event Notification with Monitoring Resources using
External Agent. I want to set notification on node failover from HA
perspective.
I follow below links
1)https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Configuring_the_Red_Hat_High_Availability_Add-On_with_Pacemaker/s1-eventnotification-HAAR.html
2)http://floriancrouzat.net/2013/01/monitor-a-pacemaker-cluster-with-ocfpacemakerclustermon-andor-external-agent/
3)http://clusterlabs.org/doc/en-US/Pacemaker/1.1-crmsh/html/Pacemaker_Explained/s-notification-external.html
Configured ClusterMon resource as
# pcs resource create ClusterMon-External ClusterMon --clone user=root \
update=30 extra_options=-E /var/lib/pgsql/9.3/data/test.sh -e
172.26.126.100
vim test.sh
if [[ ${CRM_notify_rc} != 0 ${CRM_notify_task} == monitor ]] || [[
${CRM_notify_task} != monitor ]] ; then
# This trap is compliant with PACEMAKER MIB
#
https://github.com/ClusterLabs/pacemaker/blob/master/extra/PCMK-MIB.txt
/usr/bin/snmptrap -v 2c -c public ${CRM_notify_recipient}
PACEMAKER-MIB::pacemakerNotification \
PACEMAKER-MIB::pacemakerNotificationNode s ${CRM_notify_node} \
PACEMAKER-MIB::pacemakerNotificationResource s ${CRM_notify_rsc} \
PACEMAKER-MIB::pacemakerNotificationOperation s ${CRM_notify_task} \
PACEMAKER-MIB::pacemakerNotificationDescription s ${CRM_notify_desc}
\
PACEMAKER-MIB::pacemakerNotificationStatus i ${CRM_notify_status} \
PACEMAKER-MIB::pacemakerNotificationReturnCode i ${CRM_notify_rc} \
PACEMAKER-MIB::pacemakerNotificationTargetReturnCode i
${CRM_notify_target_rc} exit 0 || exit 1
fi
exit 0
But when failover occur there is no any notification. Where should I check
notification on 172.26.126.100 ip. I repeated these steps on both primary
and standby as I have 2 node HA.
Is it correct whatever I did?
Thank You,
Ranjan

[Linux-HA] Antw: Monitor a Pacemaker Cluster with ocf:pacemaker:ClusterMon and/or external-agent
Hi! Sorry for not answering you question, but I'l like to piggy-back more questions: crm_mon has options to send SNMP traps and E-Mail, it seems. However there is _very_ little documentation on what will trigger such events, and what will be the content of such events created. I wondered whether this solution would also work: Save the output of you favorite crm_mon -1 into some file. Then save the output of cibadmin -Q |md5sum in another file. A monitoring process would recalculate the MD5 and compare it to the stored version. If the current MD5 differs, The process would output a diff between the last favourite crm_mon output and the current one. It's kind of primitive, but it should work. Preferrably that monitor should be HA by itself, so if a node is shot, there's still a chance the commands are executed...
