Purpose of this Document: 

This document demonstrates how to configure backup log collector when default log collector cluster is down. You may run into a situation where all nodes in versa analytics cluster are down and need 3rd party log collector or another Analytics cluster as a backup. 

 

Side Note: As of current implementation, when backup log collector takes over, sessions wont fall back to Primary log collectors automatically. Manual intervention is needed to switch the sessions from backup log collector to primary log collector such as disabling the backup server itself. Please refer below highlight to disable the server.


Configuration Steps:

 

  1. Add 3rd party log collector - if there are multiple servers, like in the case of analytic cluster, add all the servers one by one on the controller under “Local Load Balancer” tab. 

 

 

Field Explanations

Name

Any random name. It must be unique among the servers configured locally. 

Type

The protocol UDP/TCP/HTTP over which packets are exchanged between the server and controller

IP Address

IP address of the server

Port

The port number over which the server listens for the log.

Routing Instance

The routing instance over which the server is reachable

 

    2. Create a new server pool and add the 3rd party server or cluster server under Local Load Balancer. 

 


Field Explanations

Name

Any random name. It has to be unique among the servers configured locally. 

Type

The protocol UDP/TCP/HTTP over which packets are exchanged between the server and controller

Load Balancing Algorithm

Click on the drop-down menu and select the desired algorithm


Click on the Plus (+) button to add the 3rd server:

 

    3. Add the 3rd party server pool as a backup pool in virtual service section.
