Linux Network Monitoring

Monitoring services using Zabbix

zabbix

For critical production servers and services, monitoring is very critical. One is to get notified about issues immediately and the second is to resolve quickly hence not affecting SLA. Here, I will be showing you how to monitor systemctl services using Zabbix, basic Zabbix template and very easy Linux commands. The traditional way of monitoring services is by monitoring the ports associated with the services, however in some cases/environments, critical services have to be monitored E.g. (squid), hence in this post, you will see how to monitor services using service names and not ports on linux servers.

Note: To do this, you should already have Zabbix monitoring tool installed in your environment.

First, check the services running

systemctl | grep running

Take a note of whatever service name you will want to monitor, Log in to your Zabbix console and create a new template and application.

Configuration -> Templates -> Create template

Create New application on Zabbix console  – > systemctl status

Create individual Alert triggers

Trigger expression

{service monitoring using systemctl:system.run["systemctl status chronyd | grep -q running;echo $?"].last()}=1

Please change the service name in the expression to your configured service name. Once Items and triggers have been created on the services needed, test or simulate the new configurations by stopping services.
