UserParameter returns nothing

[akbar415]

I create a small script to do tnsping through Zabbix.

#!/bin/bash

instance=$1

tnsping=/opt/app/oracle/product/11.2.0/client_1/bin/tnsping

var1=$($tnsping $instance)
var2=$(echo $var1 |grep -Eoh '[0-9]* msec' |grep -Eoh '*[0-9]*')

echo $var2

In zabbix agent I set it up:

UserParameter=tnsping[*],/opt/scripts/pingOracle.sh $1

If I run /sbin/zabbix_agentd -t tnsping[ORACLE1]

I get

tnsping[ORACLE1]  [t|15240]

But from zabbix server running zabbix_get -s servername -k tnsping[ORACLE1] I get a empty response.

TImeout in zabbix server and agent is 30.

Even if the Timeout setting is extended to 30 seconds, processing that takes more time can not be acquired with UserParameter.

For example, please periodically run it with cron etc., output it to a file, and specify UserParameter to get only the result value from that file.

I timed the comand (/sbin/zabbix_agentd -t tnsping[ORACLE1]) and take 10 seconds, in the worst case, to receive a empty answer, futhermore when is Timeout problem zabbix show the message "timeout while executing a shell script".

Sometimes zabbix_agent cannot provide information to zabbix_server because of not sufficient permissions to start scripts/processes. Change log level to debug on agent side, restart agent, and repeat zabbix_get command on server side. Then check zabbix_agent.log file to be sure that there are no error messages.

I update my question with the log in debug mode.

Do you have any chance to log the execution of TNSPING? From your debug log I assume that tnsping did not start or throw an error message which was filtered out by pipe of grep's
One more option, do you mind temporarily change pingOracle script? For example, change "echo $var2" to "echo $var1" to see the full message from tnsping...
