Experiencing 3000ms-Peaks in Port-Check-Sensors



Hi all,

since some time I can observe that several sensors on different devices in our network are measured with response times of almost exactly 3000ms (varies up to max. 3030ms) on different TCP ports.

This makes these sensor states appear to be "unusual" even though they are not. I checked with a parallel running "tcping" on these hosts & ports and had max variations of 1 to 120ms here, which seems plausible to me.

Does anyone have an idea what this could be ?

Best thanks in advance !

Kind regards,
