dependencies, again | Archive | LogicMonitor Community

We continue to do battle with LM when alerts trigger due to dependent resource outages. I know the topology mapping team is working on alert suppression, but I am not convinced that will solve all problems regardless of how well they succeed. We really need a way to setup dependencies within logic modules and it should not need dozens of lines of API code each time (most of which should be made available as a library function IMO). One fresh specific example -- site with multiple firewalls in a VPN mesh running BGP. One firewall goes down, then all other firewalls report BGP is down. We care about BGP down, so we have alerts trigger escalation chains. It should be possible to define a dependency in the datapoint that suppresses the alert if the remote peer IP is in a down state. There is no way to express this in LM right now and that leads to many alerts in a batches, and that leads to numb customers who ignore ALL alerts.
