Troubleshooting

Installing and configuring Zabbix can happen without a hiccup for one user and with a constant stream of problems for another. The reasons for the problems can differ from user to user—buggy libraries, bad distribution packaging, unintuitive configurations in Zabbix, or maybe even an occasional bug in Zabbix itself. Here, we will look at common problems new users experience when performing various tasks:

  • Setting up the initial Zabbix installation
  • Working with the web frontend
  • Monitoring different devices
  • Configuring thresholds and alerting

If you face a case that is more complicated than that, we will continue with more detailed debugging instructions, including:

  • The Zabbix log file format
  • Reloading the server and the proxy configuration cache
  • Controlling running daemons
  • Observing the work performed by individual daemon processes
