Hi,
There is a discussion about a feature that "crm_mon" displays
the failcount in this list before,
http://www.gossamer-threads.com/lists/linuxha/users/47607
I'm trying to implement it now. It's working.
To start with, I look into the "crm_mon" code.
When crm_mon get executed with html mode,
cl_perror function will be always called and complain about opening a file.
See attached patch.
It is made for Pacemaker-0.6 (fd8904c9bc67).
And if crm_mon actually fails to open a file,
We can see some error messages, but the exit code of crm_mon itself will
be "0" as no error.
It's kind of odd.
Best Regards,
Satomi Taniguchi
