Re: [ClusterLabs] Issues with crm_mon or ClusterMon resource agent
Hi, I would like to understand if anybody has got this working recently. Looks like I have missed something in the description and hence the problem statement is not clear to the group. Can I enable some logs in crm_mon to improve the description of the problem ?

[ClusterLabs] Issues with crm_mon or ClusterMon resource agent
Hi, I wanted to configure ClusterMon resource agent so that I can get information about events in the pacemaker cluster. *Objective is to generate traps for some specific resource agents and/or conditions* My cluster installation details : pacemakerd --version Pacemaker 1.1.11 Written by Andrew Beekhof corosync -v Corosync Cluster Engine, version '1.4.7' Copyright (c) 2006-2009 Red Hat, Inc. crm_mon --version Pacemaker 1.1.11 Written by Andrew Beekhof I followed the following documentation http://clusterlabs.org/doc/en-US/Pacemaker/1.1-crmsh/html/Pacemaker_Explain ed/ch07.html http://floriancrouzat.net/2013/01/monitor-a-pacemaker-cluster-with-ocfpacem akerclustermon-andor-external-agent/ My current cluster status shows: MonitorClusterChange(ocf::pacemaker:ClusterMon):Started stvm4 The resource agent is configure The crm_mon is indeed running as a daemon on the node stvm4 [root@stvm4 panidata]# ps -ef | grep crm_mon | grep -v grep root 2908 1 0 10:59 ?00:00:00 /usr/sbin/crm_mon -p /tmp/ClusterMon_MonitorClusterChange.pid -d -i 0 -E /root/panidata/testscript.sh -e anonymous -h /tmp/ClusterMon_MonitorClusterChange.html My test script is the following #!/bin/bash echo "running" >> /root/running.log echo "CRM_notify_recipient=$CRM_notify_recipient" .. As I trigger events by shutting down one or the other service, I see the html file "/tmp/ClusterMon_MonitorClusterChange.html² getting updated each time an event is triggered. So the timestamp of the file keeps on changing. But I am not sure if the script is getting executed. Because I don¹t see any ³/root/running.log² file. Things I have tried: * Using ³logger² command instead of echo. * Running the crm_mon command with -d and other parameters manually to check , if it is the problem with resource agent etc. Queries: * Is this a know issue ? * Am I doing something incorrect ?
