Hello,
My name is Adil, my company is testing the Centreon HA cluster to monitor our infrastructure for 13 companies, for now we are using the 100IT license to test the platform, once everything is working fine then we can purchase a license suitable for our case.
For scenario 1: setting up Centreon HA Cluster with Master & Slave and VIP address on the same network (VLAN) it is working fine.
We're stuck at scenario 2: setting up Centreon HA Cluster with Master & Slave on a different datacenters.
Scenario 1: Cluster on Same network (same DC) ==> works fine
Master in DC 1 VLAN 1: 172.30.9.230 /24
Slave in DC 1 VLAN 1: 172.30.9.231 /24
VIP in DC 1 VLAN 1: 172.30.9.240/24
Quorum in DC 1 LAN: 192.168.253.230/24
Poller in DC 1 LAN: 192.168.253.231/24
Scenario 2: Cluster on different networks (2 separate DCs connected with VPN) ==> still couldn’t figure it out
Master in DC 1 VLAN 1: 172.30.9.230 /24
Slave in DC 2 VLAN 2: 172.30.10.230 /24
VIP: not sure if a public static IP from our internet service provider will work or not!
Quorum: 192.168.253.230 /24
Poller: 192.168.253.231 /24
Our goal is to have an HA cluster acros 2 different sites, so when Site A goes down, we keep monitoring with the slave on Site B.
The problem is that we didn’t find a centreon guide to use for this case? Nor what kind of VIP address will work? or how can the VIP address work in this scenario?
Also, can we use a backup poller and quorum? so if the poller 1/quorum 1 on Site A goes down, then the poller 2/quorum 2 on Site B can take the lead?
we looked everywhere (The watch, youtube, Reddit, Github...), and we still couldn't get a workaround!
the guide we used to deploy the 2 Nodes Cluster: https://docs.centreon.com/docs/installation/installation-of-centreon-ha/overview/
attached the 2 DCs architecture example, and also most of the required screenshots/config.
We appreciate your quick support, our top management wants this Project to be finalized asap so we can monitor the whole infrastructure of our 13 companies.
Thank you in advance.
