Setting up a high availability (HA) monitoring envirnoment between two SONARPLEX devices.
The instructions are based on the example setup as described below.
This is the SONARPLEX HA master device which contains the productive host- and servicechecks.
IP-Address | 172.16.0.100 |
---|---|
azeti Agent Port | 4192 |
azeti Agent Password | SamplePW |
This is the SONARPLEX HA slave device which is completely empty and contains no productive information.
IP-Address | 172.16.0.200 |
---|
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:
Create new host with the IP of the SONARPLEX HA master, in this case 172.16.0.100.
To verify the functionality of the high availability setup on your SONARPLEX devices, follow these steps:
Failover behavior: automatic, HA mode 0: Monitor process is up, last complete syncronization: 2014-08-20 08:13:28 (302 files) |
Let the SONARPLEX HA slaves service check "check_azeti_ha" run through the following HA modes:
Check result | HA mode |
---|---|
OK | HA mode 0: Monitor process is up |
WARNING | HA mode 1: Machine seems to be down |
CRITICAL | HA mode 2: Machine seems to be down |
2nd. CRITICAL | Machine reboots with HA master configuration |
The SONARPLEX HA slave is about to reboot with all configurations, log files and graphs from the last complete syncronization.
