Today I wanted to monitor Linux ISG sessions in Zabbix.
By entering the command on one of the servers:
/opt/ISG/bin/ISG.pl show_count
Saw the following:
Approved sessions count: 2021
Unapproved sessions count: 2
The Zabbix agent on the server has already been installed, so it opened its configuration file (in the nano editor, the Ctrl+X keys for the exit, and y/n for saving or canceling the changes):
nano /etc/zabbix/zabbix_agentd.conf
Invented and added the following code:
UserParameter=isg.approved, /opt/ISG/bin/ISG.pl show_count | grep "Approved sessions count:" | awk '{print $4}'
UserParameter=isg.unapproved, /opt/ISG/bin/ISG.pl show_count | grep "Unapproved sessions count:" | awk '{print $4}'
We will allow Zabbix agent to work as root with the user specifying:
AllowRoot=1
Restart the Zabbix agent to apply the changes:
sudo /etc/init.d/zabbix-agent restart
On the Zabbix server, create an ISG template, add the data elements to it, specifying the type – Zabbix agent, and the keys: isg.approved, isg.unapproved.
Create graphics for the created data items.
Apply the template to the desired nodes of the network.
Done.
