ocf:pacemaker:ping is recommended as a replacement for pingd RA
Both RA define node attribute "pingd" by default, I think this question arises
a lot, since crm ra meta for both agents is misleading:
# crm ra meta ocf:pacemaker:ping
name (string, [undef]): Attribute name
The name of the attributes to set. This is the name to be used in the
constraints.
I think it should say "pingd" instead of "undef"
Obviously, you can redefine any name you like and use it instead, but,
unfortunately, "pingd" is the only attribute name that crm_mon -f would
display, the name is hardcoded in crm_mon.c:
if(safe_str_eq("pingd", g_hash_table_lookup(rsc->meta, "type"))) {
this is inconvenience for multi-homed clusters where you need to define
separate ping clones for each network, so maybe crm_mon should display
attributes starting with "ping". Just a thought.
