Re: THRUK

Nagios Fusion exists to offer a "single pane of glass" for multiple Nagios Core instances. It doesn't interface directly with Thruk, but if the original Nagios Core CGIs are still reachable, Fusion should work fine. Assuming you wanted the entire state of all zones to be held by a Nagios ...

Re: response time in Nagios Core JsonQuery

My intention in posting those GitHub issues was to indicate that there are known inefficiencies within those CGIs. jfrickson indicated ( in #271 ) that eliminating portions of the report can provide some performance gains. Throwing hardware at the problem (as suggested by npolovenko via a ramdisk) i...

Re: Clustering of two Nagios Log Server

Add a "step 1.5" to wipe all existing ElasticSearch data and cluster state, and it *MIGHT* work. Trying to join 2 individual ElasticSearch nodes with individual data and cluster state into a 2-node cluster doesn't generally work out well. Particularly with each individual node likely shari...
