Sensor History Clearing



Hi, I am using PRTG x64. I have created PING sensor to monitor connectivity from head to remote office. Everything works perfectly. I can use pause command or maintenance windows to temporarily stop sensor monitoring while I perform system maintenance. I have a question: How can I put comments at some specific times on history of sensor and mark them as known error and don't allow sensor calculates these times into its up-time? Example: Yesterday, some people forgot to turn power on, so it caused the connectivity monitoring was down. I was told this morning about this and want to clear history of sensor last night and mark it as "problem with power" Thanks

thank you very much for your KB-Post. I'm very sorry, but it's not possible to flag or tag down times in PRTG afterwards. Planned Downtimes/Maintenances should be addressed with Schedules/Maintanance Windows. Otherwise you can access the Historic Data via the PRTG API (Setup->PRTG API->Historic Data), and then perform Reports and such Tagging of down times externally.

best regards.
