How to alert based on rate of disk consumption, not percentage free.

I'm resurrecting this request four years later because there was a suggestion that this capability might someday be implemented. Has there been any progress on this? I too need to monitor the rate of change of a sensor.

In my case, it's not disk space, but a custom sensor that monitors the number of items in a mailbox, which alerts us to spammers that have compromised user accounts from phishing attacks. Time is critical in these events, and we need to be alerted to a sudden spike in the number of items, without knowing what the baseline number is.

David, thank you very much for your KB-Post. I'm very much afraid this has not been implemented, because it is a quite complicated topic, and the requests have been very few for it.

Thanks. I ended up accomplishing the same thing using a script being called by a PRTG custom sensor.

@David, can you please share the Script, we want such infos too :)

Any more progress on this? I need to monitor the disk consumption as well.

@david can you post your custom sensor details?

Hello rrael,

a derivative (meaning rate of change) limit is currently not planned, because other features are in higher demand and this time.

We have a need for this also - as have had several instances where increased or verbose logging on various servers has gone unchecked, eventually resulting in urgent action being required out of hours. I suspect many users would like it but havent asked or are unaware of the possibility. I would say this request should be a top 10 for PRTG. Its a preventative measure rather than an ambulance at the bottom of a cliff.

Hello,

thank you for your input.

Feature requests can now be made through this process. Please allow me to be frank: For the time being, we don't plan to implement a notification trigger operating of data derivatives. The reason ist that other features on the roadmap currently are in higher demand.
