[Pacemaker] ClusterMon

Hi folks,
I'd like to use crm_mon for monitoring & email notifications, but I've
hit a snag when it comes to incorporating it into the crm
configuration. When I run crm_mon manually from the command line (with
no cluster crm configurations), it all works great, but obviously
running crm_mon on every cluster member manually would result in a
litany of duplicated messages for each resource migration, which is why
I'm looking to incorporate it into the cluster. Unfortunately, the
exact same crm_mon configuration, when entered into the cib, fails to
work, and doesn't print out any errors. To get the crm_mon
configuration into the cib, I first tried using the scriptable crm
utility, but it didn't seem to like that very much:
# crm configure primitive ResourceMonitor ocf:pacemaker:ClusterMon
params pidfile="/var/run/crm_mon.pid" htmlfile="/var/tmp/crm_mon.html"
extra_options="-T ops at example.com -F 'Cluster Monitor
<ClusterMonitor at example.com>' -H smtp.example.com:25 -P '[LDAP Cluster]:

I know those are valid options since it works from the CLI, so I tried
going through the crm shell instead, hoping it was just an interpolation
issue or something like that. That approach appeared to work (albeit
with a timeout threshold warning):
crm(live)configure# primitive ResourceMonitor ocf:pacemaker:ClusterMon
params pidfile="/var/run/crm_mon.pid" htmlfile="/var/tmp/crm_mon.html"
extra_options="-T ops at example.com -F 'Cluster Monitor
<ClusterMonitor at example.com>' -H smtp.example.com:25 -P '[LDAP Cluster]:
Resource Changes Detected'" op monitor interval="10s" timeout="20s"
WARNING: ResourceMonitor: default timeout 20s for start is smaller than
the advised 90
WARNING: ResourceMonitor: default timeout 20s for stop is smaller than

crm(live)configure# commit
WARNING: ResourceMonitor: default timeout 20s for start is smaller than
the advised 90
WARNING: ResourceMonitor: default timeout 20s for stop is smaller than
the advised 100
crm(live)configure# exit
bye
After adding it via the crm shell, the crm_mon daemon is definitely
running (and migrates to another node if I shut down or restart corosync
on the node currently running crm_mon), but I'm not getting any email
messages. My mail sever logs confirm the message never gets there when
the crm_mon configuration is in the cluster. This same command works
when run manually from the command line, and there are no errors or
warnings in the logs, so I'm not sure what to attribute the problem to.
Here are the cluster log messages resulting from a simple resource
migration on the host running the crm_mon daemon that was spawned by the
cluster:

Other than the monitoring, everything seems to work pretty well, but I
don't want to deploy this in production without a good real-time monitor
of the resource changes, so I'd appreciate any suggestions as to why
crm_mon works when run manually, but not when configured in the
cluster. For reference, I'm running on Ubuntu Server 10.04 LTS (Lucid),
and these are the packages I'm using:
cluster-agents 1:1.0.3-2ubuntu1
cluster-glue 1.0.5-1

libcluster-glue 1.0.5-1

Thanks!
