Port Number Details for configuring load balancer

[anish]

Hi ,

We would like to configure load balancing in our new Nagios Log environment .

We have got the VIP IP address now.
Please confirm on the port details which needs to be opened to access Load Balancing for Nagios Log environment.

VIP is a bit above what we can provide support for. You will need to configure load balancing on your own as well as VIP.

Elastic uses just needs 9200 / 9300 open (9200 for db calls, 9300 for communicating with cluster members)
Logstash uses whatever input ports you have defined
Kibana uses 80 / 443

Thanks Kennedy ,

Is there a guide for "how to configure Nagios Log server using VIP " ?

Not currently. All sorts of topics related to load balancing are considered out of scope, though we can offer basic advice in how to best distribute work between multiple NLS nodes. Rather than going to VIP route, I know of a couple customers who configure a round-robin DNS. Though that isn't "true" load balancing it's certainly better than no load balancing.

In the case of a VIP, I imagine it would function in much the same way. You would just point your agents (rsyslog/nxlog) at the VIP and let the broker for the VIP determine which node gets the traffic.
