[Pacemaker] Additional help with ClusterMon

[Michael Furman]

I was able to run the ClusterMon agent.



Couple of comments:

1.      
When I uses ocf:pacemaker:ClusterMon it crashes a lot with the
following core file:



file
core.22992

core.22992: ELF 64-bit LSB
core file x86-64, version 1 (SYSV), SVR4-style, from '/usr/sbin/crm_mon -p
/tmp/ClusterMon_ClusterMon.pid -d -i 0 -E /usr/local/bin/e'

 

2.      
I required to use ocf:heartbeat:ClusterMon. I found the way to
configure it with pcs:

pcs
resource create ClusterMonScript1  ocf:heartbeat:ClusterMon params
user="root" update="30" extra_options="-E
/usr/local/bin/example.sh" op monitor on-fail="restart"
interval="20"





Unfortunately, ClusterMon get only resource oriented event. In
addition, it does not get event on the node that become stand-by and get the
event only on the node that become master.



 

I want to do get the following events:

1.      
On the node that become
from active to stand-by the event that tell: “the node become from active to stand-by”



2.      
On node that become from standby
to active the event that tell: “the node become from stand-by to active”



Questions:



1.      
How it possible to
configure ClusterMon to get such functionality?

2.      
Is exists other agent that
allows me to get events described above?

Thanks for your help,

Michael
