Thanks for the feedback. I have run through the instructions from curtisi:
The custom report and schedule broadly works as described:
The default path to save the new custom report (from the filtered export) is in documents of the home folder. I copied the files across to C:\Program Files (x86)\SolarWinds Log and Event Manager Reports\CustomReports and refreshing the custom reports window brought these up. They could then be scheduled like any other report.
I have done this with 2 reports, one on log on failures and another on authentication. When these new custom report *.rpt files are run by loading them in the report viewer, then they are 1 or 2 pages long for a day's worth of data. When run through the scheduler these same reports are 120+ pages long. There are very few options to choose when scheduling a report. Basically when to run it, what to do with the output and how long a time scale to collect data for. It appears that the filtered parameters that I added and which must be saved in the *.rpt document (as they kick in when the report is opened manually) are not being read by the scheduling program (which is pretty much the built in Windows task scheduler). Am I missing something in the set up?
