I'm using Pulseway to monitor about 10 servers in my domain. Most of these run in a VMWare environment. Last night and this morning I received notifications that servers were offline. The first notifications involved 2 virtual servers running on the same physical host. The third and fourth notifications were for 2 other virtual servers, both of which were running on different physical hosts than the first 2 VM's. My first thought was that there was a network hiccup that caused the Pulseway agent to lose contact on these servers. However, here's the problem with that assumption. Every server that Pulseway reported as offline was running on a physical VMWare Esxi 5.5 host that was hosting other virtual servers that Pulseway was monitoring. Those other servers never reported a problem. If any of the physical hosts had experienced a network hiccup it should have affected all of the VM's that were monitored by Pulseway. This didn't happen. Is my thinking correct here? This is probably the fourth time that I have had servers report as offline when they were not and it's creating doubts as to whether Pulseway is something I can count on. I would like to get this straightened out as I love the Pulseway functionality. Looking forward to what the forum suggests.
