check_apachectl + general $ARG question

[lraymond]

Close to having my apache monitoring in place, just a little unsure if I need a seperate host due to another IP. Basically I am using nrpe on custom ports per host getting a lot of good data, disk, ram, etc. Next is apache. Using the nagios server and the command from the cli things work perfect;

check_apachestatus.pl -H 1.1.1.1 -p 81
OK 0.255079 seconds response time. Idle 6, busy 43, open slots 207 | 'Waiting for Connection'=6 'Starting Up'=0 'Reading Request'=2 'Sending Reply'=3 'Keepalive (read)'=38 'DNS Lookup'=0 'Closing Connection'=0 'Logging'=0 'Gracefully finishing'=0 'Idle cleanup'=0 'Open slot'=207 'Requests/sec'=13.0 'kB per sec'=213.0kB 'kB per Request'=16.4kB

That above -p 81 says use port 81 which goes to server 1. -p 82, server 2, etc. My problem is understanding the $ARG's with nagios. I'm sure it's just a definition, but here is all the parts from the command down;
# check_apachestatus.pl -H [-p ] [-t ] [-w -c ] [-V]
define command{
command_name check_http_stat
command_line $USER1$/check_apachestatus.pl -H $HOSTADDRESS$ $ARG1$
}

define host{
use lbremote
host_name WS1
address 1.1.1.1
_tcport 5671
}

define service{

host_name WS1,WS2
service_description Apache Check
check_command check_http!-S -a nagios:nagios2check
}
define serviceextinfo {
service_description Apache Check
host_name WS1,WS2
use basic
}

define service{
use generic-service,srv-pnp
host_name WS1,WS2
service_description Apache-Load
check_command check_http_stat!-w 30 -c 15
}
define serviceextinfo {
service_description Apache-Load
host_name WS1,WS2
use basic
}


So, the command say's $ARG1$ after the host address. Naturally I don't want it to use the NRPE port, so how and where do I say WS1 = port 81, WS2 = port 82, etc. Naturally got a txt his am with issues, and I have load, RAM, space, etc. but no apache which is what's giving issues, so would love to have that info!

The other issue is using the above I was getting errors with the serviceextinfo saying the basic template could not be found. I guess that's what the developer had, but I tried using my lbremote one as well as generic-serivice which still didn't work so I commented out the extinfo, then it did restart and I changed the command to be;
# check_command check_http!-S -a -p 81 nagios:nagios2check
to give errors on the 2 checks;
critical - (Return code of 126 is out of bounds - plugin may not be executable)

So I am going to continue my reading, thank as always!

serviceextinfo is actually deprecated, it's a legacy object for compatibility with people upgrading from older versions... the standard service definition object now supports all the arguments that extinfo used to do; so there is no need to use it.
