Few problems about Centralized and Distributed Monitoring and Nagios process

[David Suen]

Hi list,

         I setup a Centralized and Distributed Montoring system which 
currently monitoring 15 hosts and have 69 services altogether using passive 
check with check freshness enabled.

         Both Central and Distributed Servers seems fine however I have the 
following problems and see if anyone in here can help me:

1) In central server, sometimes when do the ps it shows that nagios has 
more than 70 processes. Anyone in here has idea why and how to solve it? Or 
I have to write a script, put it in the cron and check it (which I dont 
want to if possible)?

2) Central Server said does not receive any passive check from one of the 
distribute servers. However when I check the distribute server it does run 
...../send_nsca...... . Once the distribute server marked as down (due to 
does not receive any passive check after "check_freshness" sec), it takes 
really long time (1-2 hours about) to make the host is up again (I think it 
can receive the passive check again). Furthermore, it seems the central 
server does not do any active check when the passive check data is staled 
and sometimes I have to restart the nagios in that distribute server then 
wait for awhile to make the central server receive the passive check again. 
It only happened in one distribute server.


3) One of the service in one of the server marked as down ("No data 
received from host"). I clicked that host using web interface and click 
"Schedule an immediate check of all services on this host" but it still 
remain the same after almost an hr. Moreover the central server also does 
not run any active check after the data become stale.

         If these problems is due to the mis-configuration in the 
configuration files where should I take a look? Currently I set the 
freshness is 5 mins (300 sec).

         Thanks a lot.
