Monitoring & Alerting

You can use hook scripts to setup and configure monitoring on your croit installation.

Hook Script Library

croit ships with a hook script library with the following options:

Monitoring

• CheckMK
• SNMP
• Zabbix

The monitoring scripts install their agent on every server each time it boots. Before you add one, check what it needs:

• CheckMK downloads the agent from your CheckMK site and registers the server with it. Create each server as a host in the site first, under the same name croit shows for it, and enter the site's hostname or IPv4 address without a port: the script reaches the site over HTTP on port 80. CheckMK's agent controller does not accept an IPv6 address, so a site reached over IPv6 needs a hostname.
• SNMP installs net-snmp from the AlmaLinux package repositories, so your servers need to reach them. If the install fails, the script stops there and reports a non-zero exit instead of configuring snmpd.
• Zabbix downloads the agent from repo.zabbix.com, so your servers need to reach it.

To try a script before your servers reboot, select it under Config → Hook Scripts and click Execute. The task log shows the script's output and its exit code.
