Zabbix External check

[Harry Han]

Hi Guys.

I need your help. Thanks in advance!
I have installed zabbix 2.4.6, and is monitoring a linux host via SNMP. I didn't install any agents on the linux host. Now I'm trying to monitor the "top" status on the linux server using external check.
my script is quite simple:
[root@localhost externalscripts]# cat check_top_status.sh
#/bin/bash
ps aux |grep top |wc -l

The script is under the right path and is executable.

Then I set the following external check configuration in the zabbix GUI.
Name check_top_status
Type External check
Host interface 192.168.1.199:161
type of information Numeric
Data type Decimal

My problem is my zabbix only can get the top status from zabbix server, not the linux server which I want to monitor. I don't know where is wrong as I didn't find any detailed document for external check. Hope you can point out help me resovle the problem. Thanks again!

Feel your script with {HOST.CONN}, {HOST.DNS} or {HOST.IP} macro and run command on this host remotely with ssh.
