We've been running IPMonitor for a couple of years - currently on version 9.01. Since rebooting the server a couple of days ago all our reports are showing no data, just a '-' where the values should be.
'Store Monitor Statistics for Recent Activity and Historical Reports' is checked for all the monitors and the reports have been running ok for about 6 months. It's like it's lost the connection to it's own database.
Can anyone offer any suggestions where to start troubleshooting this one?
I have had the same issue many times in the past which only came up after upgrading from 8.5 to 9.01. We are currently running into the same issue with 9.06 after the we were told to upgrade to resolve the issue.
I have found it only happens at random times, and is usually caused by having a large number of specific monitors as a reports data source. When the issue happened for me, the data source was completely removed from the report template, and I had to set it all up again.
Since changing the report from using specific monitors to using smart groups, the issue has not returned. It has been around 2 months without an issue since making this change.
