I have one Log Server, and we are getting ready to add a second one.
The first LS is using an NFS share on our Isilon to store logs.
When I spin up the second LS, can it also use that same store on the Isilon?
Common log store for multiple instances?
Re: Common log store for multiple instances?
Are these two instances being clustered? If so, they need to use the same store:

Yes, they will be in the same cluster.cdienger wrote:Are these two instances being clustered? If so, they need to use the same store:

Per that document, they need to use the same snapshot repository.
Can both servers also point their /usr/local/nagioslogserver/elasticsearch/data/ to the same store as well?

It could be the same store but would need to be a different path on the store.chud wrote:Can both servers also point their /usr/local/nagioslogserver/elasticsearch/data/ to the same store as well?
One thing worth pointing out also is that by using the same storage device you still have a single point of failure, and if you lose the store, you would lose your whole clusters worth of data.

Thanks.
One more question/scenario: just out of curiosity, could we build our own multi-node ElasticSearch cluster, and point our two Nagios Log Servers at it, say if it was behind haproxy and had a vip to use as an entry point? Is Nagios Log Server able to use external ElasticSearch?

This may be possible in addition to the built-in ES (not instead of) using custom outputs in the Logstash, but we would not be able to provide supported for this setup.chud wrote:Thanks.
