Auto Balanced Collector Group vs Failover?

Hi, I'm wondering if there are pros and cons vs setting up multiple collectors as an ABCG vs stand-alone collectors with failover.  If we have two collectors in the same location, monitoring the sam...

    If you have collectors in different regions, you would want to avoid Auto Balanced. This would be more meant for traditional failover. As with traditional failover, your devices will be monitored by the collector you pick, generally the closest. But if something were to happen to that collector, the back up would try to take over.

    With Auto Balanced, while yes, the other collectors try to take over when 1 is down, you can end up with a collector with a horrible connection being the main collector. Auto Balance only works off of instance counts, and only balances when that threshold has been exceeded.

As far as I know, ABCG isn't that intelligent. nor does it mention along those lines at https://www.logicmonitor.com/support/collectors/collector-groups/auto-balanced-collector-groups. I wouldn't suggest doing ABCG across sites.

Note, you may want to be careful about even normal fail-over to a different site. If a site goes down due to internet or power, all the devices would switch over the other site's collector. Since that collector is live but can't reach all those devices, it's going to alert on each and every device at that site as being down. I believe the Dependent Alert Mapping may help prevent that issue though.

    Yeah.  That's what I was thinking.  Thanks.
