Good day,
I posted a message to the nagios-users list awhile back about a problem with
Nagios not executing service checks- they are properly scheduled, just never
executed. I believe I have found at least one cause of this, which
certainly appears to be a bug, so I'm posting a message here.
We recently had 7 of our 203 hosts temporarily become unreachable due to
ACLs. When they went down, I noted that Nagios didn't check any services
while it performed its host-check commands. As a result, almost none of the
service checks were performed for 30-45 minutes. I presume that this is a
bug / undesirable behavior.
Furthermore, I noted that if Nagios was restarted (I am retaining state
information, BTW), the same thing would occur- it would take 30-45 minutes
for most service checks to run for the first time, even though Nagios
reported that they were scheduled for execution much, much sooner than that.
Nagios didn't log that it was trying its host checks then- I presume because
the machines and their services were already marked as down.
I loaded this configuration on a separate machine that did not have the ACL
problem, and noted that service checks were performed normally.
I hope that this is enough information to have this bug fixed. Please reply
if there's anything else that I could supply.
I'm running a late 1.0b4 CVS copy on RH 7.2 .
Thanks in advance,
