Use Case

Setting up a high availability (HA) monitoring envirnoment between two SONARPLEX devices.

Example Setup

The instructions are based on the example setup as described below.

HA Master

This is the SONARPLEX HA master device which contains the productive host- and servicechecks.

HA Slave

This is the SONARPLEX HA slave device which is completely empty and contains no productive information.

The slave runs just one single HA service check to maintain HA capabilities. This service should run in short intervals (3-5 min.) to reduce the outage times and gaps in logging and graphs.

The general procedure is as follows:

1. Configure the SONARPLEX HA master as the productive device. No further configuration is necessary.
2. Configure the SONARPLEX HA slave with just the host of the HA master. Add a servicecheck to that host with the template "check_azeti_ha".
3. Let the SONARPLEX HA slave run this servicecheck to start syncronisation.
