does anybody use Nagios here, i need help regarding check_snmp to monitor Server

[bicky]

hi gatt,
somehow i dont have hostgroups.cfg. but my nagios works fine:

is it necessary to create .cfg file for each hosts with all the services. Isnt there anyway where we can have a single cfg file with list of services and another file for each host which will pull the services details from the services cfg file.

currently i have something like this:

host1.cfg
define host
define service a
define service b
define service c
define service d
define service e
define service f
define service g


host2.cfg
define host
define service a
define service b
define service c
define service d
define service e
define service f
define service g


host3.cfg
define host
define service a
define service b
define service c
define service d
define service e
define service f
define service g


host4.cfg
define host
define service a
define service b
define service c
define service d
define service e
define service f
define service g

Yes and no..
You can setup "generic" services linked to a hostgroup, that way any server assigned that hostgroup will automatically monitor those services.

See: HowTos/Nagios - CentOS Wiki

However.. I that these override any similar definitions - classic example was with HTTP! if I defined it to monitor port 80, i could not change one server to monitor port 8080!

You still, however, need to create a config file for each server you want to monitor and add it to the hostgroup - there is no getting out of that one I'm afraid.

The advantage of using generic services is that all you need in your serverXX.cfg files is the hostname, alias and IP address and any additonal services you want to monitor.

I, personally, found it easier to put everything in the serverXX.cfg file and copy/paste/edit as needed....
