Team,
I have 4 instances and F5 load balancer is enabled among them. Can you assist me how logs are moved into all the instances? and how can I validate the same?

If you added each Nagios Log Server instance to the cluster following the steps in this documentation:
https://assets.nagios.com/downloads/nag ... luster.pdf
That should be all you need to do. If you'd like to verify that all the logs are being replicated on each instance, you can login to the instances individually and run some similar queries between them.
Alternatively, you could run this command from the CLI of each instance to make sure all the instances can see each other in the cluster:
Code: Select all
curl 'localhost:9200/_cat/nodes?v'

Check out my beautiful drawing. Hope it helps explain. Think of a 4 node like a RAID10 setup.

You might find this interesting too since you're running a 4 node -

Hi Uma K, Did the above help clarify things for you? If so, is it okay to close the thread or did you have more questions?
