Distributed configuration issue with staleness (thresholds?)

[Bob Johnson]

Greetings to all,

In my test configuration, I have one server as the distributed node and
the other as the master node.  The distributed node does all of the
checking and sends its check results to the master node via NSCA.  The
checks are sent (and received) in a normal fashion to the master node, but
for some reason I am having issues with the freshness threshold on the
master server.  The nagios.log excerpt below states that the check is
stale by "7" seconds even though there is a threshold of "200" seconds. 
Therefore, I believe that I must be overlooking something in the
configuration and would appreciate any advice.  (As a side note, quite a
few services go into the stale mode at once, and not just this single
check.  However, not *every* service immediately goes stale.)


>From nagios.log on the master server:

"Warning: The results of service 'time' on host 'server1' are stale by 7
seconds (threshold=200 seconds).  I'm forcing an immediate check of the
service."


Alas, I have a few questions:

a. Where exactly is this "7" coming from (or calculated) in the
configuration?

b. Where exactly is this "200" coming from (or calculated) in the
configuration?

c. Is there a recommended complete (yet barebones) master and distributed
node configuration reference for nagios.cfg, hosts.cfg, and services.cfg?

d. Are there any other logs or additional debugging details which would be
useful for this distributed staleness issue?
