Hi
I think our monitoring system is creating ResponseTime_Detail records for nodes that we have recently deleted.
I thought that when a node was deleted, it was removed from the Nodes table, and records for that NodeID were removed from the ResponseTime_Detail, ResponseTime_Hourly and ResponseTime_Daily tables. What seems to have happened recently is that the ResponseTime_Detail and ResponseTime_Daily records are deleted, but ResponseTime_Hourly remain (but are not bundled into ResponseTime_Daily after 180 days).
Because we are checking for outages, we have found that deleted nodes are showing as being out. Records are created every 2 minutes. If the IP address still exists, all seems fine, but if it does not then Availability swaps between 0 and 100 while PercentLoss is 100. These records do not appear to get bundled into the ResponseTime_Hourly table after 30 days.
My questions are:
- Is this now normal behaviour?
- How can we stop records being created for nodes no longer in the Nodes table?
Many thanks
