After each upgrade the monitoring events seem to get wiped, has anyone else noticed this or is it just me? This seems to have been happening for a long time now, I’ve only just got around to flagging it.
I have not seen that before. I just checked our install before the 5.5.14 to 5.5.15 update and have all of the event from before.
Just supplying some feedback. Hope you figure it out.
Thanks for your reply, I think its probably our setup then, as the full backup of the simple help server hasn’t worked either. I think its possibly to do with the 1000+ toolbox jobs we have. 
I saw that happen when I went to 5.5.14 and I only have a handfull of jobs. And the restore doesn’t work either. So what good it that?
