Timeout while executing extrnal scripts

[jix]

Dears
I wrote a bash script in linux debian that try to call simulated automatic telnet script.

in telnet script i try to connect to some routers and ping some host and return ping time response time and success rate

for example

root@server:etc/externalscripts# ./telnet  10.10.33.11 My_router 8.8.8.8 

spawn telnet 10.10.33.11
Trying 10.10.33.11...
Connected to 10.10.33.11.
Escape character is '^]'.

Success rate is 100 percent (10/10), round-trip min/avg/max = 100/100/104 ms

root@server:etc/externalscripts#

in my shell script , i calculated round tripe and success rate that return from telnet script


when i run script manualy, everything working fines

but in zabbix server

sometimes my items gets error ( timeout while executing a shell script)
and some times they works.


i changed Timeout in zabbix.conf to 20 sec but problem still exist
and here is my graphs

!

here is my scripts

#!/bin/bash

if [ "$2" == "rate" ]; then
rate=`/usr/local/zabbix/etc/externalscripts/telnet |/bin/grep Success | /usr/bin/awk '{ print $4};'`
echo $rate
fi

if [ "$2" == "time" ]; then

time=`/usr/local/zabbix/etc/externalscripts/telnet  |/bin/grep Success | /usr/bin/awk '{ print $10};'|/usr/bin/cut -d'/' -f2`
echo $time

fi

!

any idea?
my scripts works manualy and takes 7 sec to complete
i set timeout in configuration file to 15 sec but no success

i think it is a bug for zabbix server

Gaps / timeout can indicate zabbix performance problems: Try look at these links:

They may be to generel ... but try search in the forum also, or ask at the IRC.
Please also check you zabbix server log.
Hope this help.
