Extract Days Until from Date string in SNMP Custom String Sensor

Modified on 2025-06-10 16:58:53 +0200

I have multiple SNMP Custom String Sensors that read the licence expiry date from different devices. Is it possible to calculate the remaining days until this date, so I can configure a channel limit and a notification trigger within this sensor? The format looks like this: Tue Feb 25 02:00:00 2025 Any other suggestions in case this is not possible?

Hello Jannik,

Usually for calculating values derived from sensor data you could use our Sensor Factory Sensors but they only work for numerical values and not for dates.
Apart from that we currently have no other solution available in PRTG.

Kind regards,
