Setting up my first pacemaker cluster, I’m trying to grasp howto make

Got this so far:
[root@afnA ~]# pcs resource
Resource Group: afnGroup
afnVIP (ocf::heartbeat:IPaddr2): Started afnA
afnNGinx (ocf::heartbeat:nginx): Started afnA
[root@afnA ~]# pcs resource show afnNGinx
Resource: afnNGinx (class=ocf provider=heartbeat type=nginx)
Attributes: configfile=/opt/imail/nginx/conf/nginx.conf port=8080
httpd=/opt/imail/nginx/sbin/nginx options="-p /opt/imail/nginx" status10url=/ping
status10regex=".+ is alive\."
Operations: start interval=0s timeout=60s (afnNGinx-start-interval-0s)
stop interval=0s timeout=60s (afnNGinx-stop-interval-0s)
monitor interval=10s timeout=20s (afnNGinx-monitor-interval-10s)
monitor interval=60s timeout=20s (afnNGinx-monitor-interval-60s)
[root@afnA ~]#
but I cant verify that pacemaker RA ever calls http://localhost:8080/ping
<http://localhost:8080/ping>, why not?
Any pointers to info source(s) for better understanding RA configuration and
maybe specially check levels?
Found this:

<http://clusterlabs.org/doc/en-US/Pacemaker/1.0/html/Pacemaker_Explained/s-operation-monitor-multiple.html>
This seemed to work much better:
[root@afnA ~]# pcs resource show afnNGinx

Attributes: configfile=/opt/imail/nginx/conf/nginx.conf port=8080

[root@afnA]# pcs --version
0.9.139
https://www.mankier.com/8/pcs <https://www.mankier.com/8/pcs> seems to indicate
a debug-monitor command only my pcs version doesn’t seem to support this, might it
only be in a later version, also I can seem to find ocf-tester from CentOS 6
repository, where might I find ocf-tester rpm?
/Steffen
Support for debug-monitor was added to pcs upstream in June of this
year; not sure what version that corresponds to.
Hi,
It's pcs 0.9.141.
It basically calls crm_resource like this:
crm_resource -r afnNGinx --force-check
Check man crm_resource for more details.
Tomas
ocf-tester is part of the upstream resource-agents package
(https://github.com/ClusterLabs/resource-agents). As I understand it, it
is not included in the RHEL/CentOS releases because it has SuSE-specific
code. It could be made more portable but it's not a high priority.
Patches welcome of course :)
