17.1. Procedure – Monitoring Zorp with Munin

Purpose: 

To monitor the Zorp Professional hosts with Munin, complete the following steps. Using Munin, it is possible to monitor the memory usage of the hosts, and the number of running processes and threads for the Zorp instances.

Steps: 

1. Login to the host locally, or remotely using SSH. For details on enabling SSH access, see Section 9.4, Local services on Zorp.

2. Install the required packages using the sudo apt install <package-name> command. Which package has to be installed depends on the role of the host.

   • For Zorp hosts, install the zorp-pro-munin-plugins package.

   • For ZMS hosts, install the zms-munin-plugins package.

   • For ZCV hosts, install the zcv-munin-plugins package.

   • If a host has multiple roles, install every applicable package. For example, if ZMS and ZCV are running on the same host, install the zms-munin-plugins and zcv-munin-plugins packages.

3. Install the munin-node package and configure it according to the needs of the environment. For details, see the Munin documentation.

4. Login to your ZMS host using ZMC, and enable access to the TCP/4949 port. For details, see Section 9.4, Local services on Zorp.

5. Repeat this procedure for each Zorp Professional host that is required to be integrated into the monitoring system.
