How do I diagnose excessive open requests?



I have over 400 open requests under probe health. Everything on the server looks fine (CPU, RAM, Bandwidth, etc.). How do I determine what the bottleneck is for these open requests?

too many sensors on one probe, scanning interval is two low, devices taking a long time to reply

these are just a few thigs that could cause this issue.

On your probe healt sensors Live Data tab which one of the "interval Delay" columns shows a significant high number for delay?

please send a screenshot to [email protected]

please forward us your system log files for analysis? You can find the same under

XP/2003: C:\Documents and Settings\All Users\Application Data\Paessler\PRTG Network Monitor\Logs (System)

Vista/2008: C:\ProgramData\Paessler\PRTG Network Monitor\Logs (System)

Please send the Logs(System) folder as a zip file if possible.

If you have changed the location of the data folder in the past or if you can not find current log files in the above location, please check your data path in the PRTG Server Administrator Tool on the PRTG server.
