Telnet check without login prompt

[daszek]

Hi,

My application has telnet CLI. I would like to use agent-less telnet check to access application's statistics. The problem is this CLI does not require login.

I have defined item: TELNET agent telnet.run[]. Then zabbix server reports error straight from </src/zabbix_server/poller/checks_telnet.c> telnet_login(...) function ("No login prompt"). This function assumes there is a login prompt and checks for ':' byte (two times - for login and password). I wish that login procedure is skipped if last byte is regular prompt ($ # > %).

Is is possible to make such change and how can it be done?

Same problem

Guys,

I am getting the same problem here.

I must monitor my SCO unix server through TELNET, because I can't change this server in this is the only access I have for this server.

You could write an external script for this....
Even with login this can be done...

You can create a script that does a login and then shows all the values you need. Then pipe them to a file on the zabbix server.....

This script can be initiated as a zabbix external script.
It can return a value if it was successful or not...

that script can parse the file and send all the subsequent keys/parameters with zabbix_sender....

Something like this.... (more a concept...)
needs to be worked out... since I'm not on your payroll....


/usr/local/sbin/stat_machine

#!/bin/sh
SUCCESS=0
host=$1
(sleep 1; echo -e "admin\r"; sleep 1; echo -e "admin\r"; sleep 1; echo -e "show config\r"; sleep 1; echo -e "exit\r") | telnet $host >/tmp/$host

if [ -s /tmp/$host ] ; then
  send_with_sender $host
  SUCCESS=1  
fi

echo $SUCCESS

Still an issue in 2.0
