Hi We have more than 1000 servers being monitored as groups under a root Probe Device. The main problem here is the wmi timeout due to which we receive more than 25% false alerts as "Connection Cannot be Established". The current Version of the PRTG is 18.104.22.16895 which I checked in official prtg release versions, I could not find this version in your list of releases any more. One of our admins had configured PRTG and left the organization long back. The Scanning Interval is set to 15 mins. I could not find the option for wmi timeout. And hence, with some research, I have opened configuration.dat file and observed that the value for wmi timeout is 5. I presume that 5 is here seconds but not minutes :) However, PRTG Official release says that the wmi count value should be 1.5x of scanning interval. Not sure.. what to do and how to move forward.
Believe it or not we are receiving more than 1000 mails nearly from PRTG which my Alert Monitoring team is working very hard and spending a lot of time in addressing these. Please take some time and suggest me for the needful to be done to resolve this issue.
I appreciate your time and kindly help. Thanks in Advance.
