Why do I get the error message
The flow processor has dropped flows. The reason might be that PRTG is not able to process the incoming flows fast enough. To resolve this issue, consider using remote probes. Also try to optimize your include, exclude, and filter rules. For more information, see https://kb.paessler.com/en/topic/24973. (code: PE111)
What can I do to troubleshoot the issue?
