SNMP Custom String sensor Extract a part of the message and graph it

I'm afraid that's not currently possible with PRTG. You can read out the string using a SNMP String sensor, but it isn't possible to separate the numeric value and use the same.

Thank you for your msg

But can we trigger a notification based on the message content ?

Like if the message is changed to :

FAN 1 : 12000 RPM and above

Thanks

SNMP Custom String sensors include the option to search the result for a specific string and include the fields, "Response must include" (if the response does not contain this string, this is considered an error and can trigger a notification) and "Response must not include" (if the response does contain this string, this is considered an error and can trigger a notification). If there is a specific string that should always trigger a notification, respectively trigger a notification if it is not in the response, then you could use this option to do the same. Otherwise, it isn't possible.

Thank you,

but with this I will not only be capable to track a fix value like 12000 no ?

If I would like to track from 12000 to above (range 12000 to 20000) ?

No, it won't. As mentioned above, it is not possible to extract the value from the string result using PRTG and, as such, it isn't possible to use limits when the counter in case returns a string.

Ok thank you,

Any plans in future to have that possible ?
