Cisco SNMP/External Checks

[jonnjonzzn]

OK, I am trying to pull active connection information from a Cisco (ACE) Load Balancer. I really only want the # of active connections to each back-end app server. I could not get a snmp check to work as has been discussed in this fourum as the "value #2 has unknow type [81]" error and also at https://support.zabbix.com/browse/ZBX-55

So, for now I figured I just do an external script and pick off the data that way however I can not get an "external check" type item to work. Here is what I have done:

1 Verified external script directory in zabbix_server.conf file is /etc/zabbix/externalscripts is correct and all permissions are correct.

Have script named checklbload.sh with correct permissions in correct directory. Have restarted server and agent.

ls -al /etc/zabbix/externalscripts
total 16
drwxr-xr-x 2 zabbix root 4096 Oct 10 15:35 .
drwxr-xr-x 3 root   root 4096 Oct 10 12:08 ..
-rwxrwx--- 1 zabbix root   21 Oct 10 14:31 checklbload.sh

Here's the script code I'm using just to test::

#!/bin/bash

exit 50

Created item in Zabbix for Zabbix server as External Check with key as follows: checklbload.sh[] with type as Numeric (integer 64).

Here's what I see in zabbix_server.log:

824:20071010:153722 Script /etc/zabbix/externalscripts/checklbload.sh returned nothing.
824:20071010:153722 Parameter [checklbload.sh[]] is not supported by agent on host [wraith] Old status [0]
824:20071010:153722 Script /etc/zabbix/externalscripts/checklbload.sh returned nothing.

Can anybody please help me?

exit 50? Why? I would use "echo 50" instead....

Ah yes, check the obvious things first... sorry. Changing to "echo" solved it.

How about the first issue referenced above though

I'm looking at checks_snmp.c to try and track it down but my C skills are rather rusty.

Thanks, Alexei!

I'd love to repllicate this problem! I tried hard with all SNMP devices I have (a couple of switches, firewall, printers, etc), no luck so far.
