Is it possible to set xx GB free space as threshold instead of percent?



Hello :)

Is it possible to set a number for a threshold instead of percent? Like a warning about 50 Gigabyte free space instead of 10 % free space.

I appreciate your feedback!

free-space percentage threshold

just check your "Disk Free" Sensor. You most likely will have a channel for "free bytes" and "free space". Click on the gear next to it and set the limits inside of the channel. Space for % - Bytes for GB.

Here some Screenshots with corresponding colors:

You would have to choose "free bytes -> Lower Warning Limit" of course... not "Upper" as in my screenshots ;-)

Just one additional thing: Careful when the WMI Free Space Multidisk sensor is being used as it also comes with pre-defined limits for the "Free Space" channels that are not visible in the channel as they are configured on "Settings" tab. Just in case :)

Kind regards,


P.S.: Thanks for chipping in, Lukas :)

This is just not working for me, nothing I do will shift the sensor from % to capacity.

I enter the capacity limits I want, and they show up as percentages.

I've tried clicking the gear wheel as advised; and the interface looks nothing like the screenshots above. I've tried altering the settings in "settings"; and the value changes OK; but the metric remains percent. That's to say, I can change 10% to 20%, I cannot change it from 10% to 20 GB.

It would be easier if I could post screen shots......

I would encourage you to create a support ticket to submit your data and provide screenshots to review configuration and so on. You can reference this KB article in the case notes.
