Pending status


#1

I tried to post it to the Nagios users mailing list but couldn’t get this resolved. So I am trying it here.

My Nagios install seems to be in a perpetual pending state. When I checked the archives, I found a lot of threads regarding this “pending” status and “Host has not been checked yet” messages that users have been getting on a fresh install. But unfortunately none of the suggestions (at least most of them) did not work for me. Hence I am posting my question (again?) - How do I get the Nagios to actually check the services? What am I missing?

Here are the config details:

define service{
name generic-service ; The ‘name’ of this service template
active_checks_enabled 1 ; Active service checks are enabled
passive_checks_enabled 1 ; Passive service checks are enabled/accepted
parallelize_check 1 ; Active service checks should be parallelized (disabling this can lead to major performance problems)

#2

can you please post the nagios.log.


#3

That is another problem I am having. My log file does not show anything more than this:

[1118410138] Nagios 2.0b3 starting… (PID=17018)
[1118410138] LOG VERSION: 2.0

Those are the only two lines (with different processids of course) it logs after everytime I restart and after that nothing. SO just out of curiosity I turned on checking for orphaned checks as this is what I get:

Warning: The check of service ‘PING’ on host ‘localhost’ looks like it was orphaned (results never came back). I’m scheduling an immediate check of the service…

This message keeps on repeating which is obvious. So I am not sure what else I am doing wrong.


#4

Please read this url and it should help you alot. I fought the same trouble myself.
nagios.sourceforge.net/docs/1_0/ … tion_notes

active_checks_enabled is one of these directives to which the above url applies. So, bottom line is
Enable checks of this service, by using the web interface link called Enable checks of this service.


#5

“active_checks_enabled is one of these directives to which the above url applies”

I am using v2.0b3 and I couldn’t find any directive named active_checks_enabled.


#6

How did you configure nagios if that is the case?

oops you are right. I was looking in the wrong cfg. But I am still experiencing the same issues.
