Reduce default "Disk Free" sensor limits.




I use sensor "Disk Free" multidisk (default tags for it wmidiskspacesensor+diskspacesensor), this sensor now in Warning state, because one of my Disk Volume is 20% Free Space, but when i change Lower Warning Limit and Lower Error Limit for it nothing happens. But if i increase this setting everything works fine! Why i can't change this setting? I want to change default setting for this channel to 15% as Warning and 5% as Error.

Thank you!

Hello Vasiliy,

Thank you for your KB-post.

Please note that in the WMI Free Disk Space (Multi Disk) Sensor you can set limits in both the channel settings and the sensors settings. The limits are valid simultaneously, so the first limit that is breached applies.

Could you please check that these two types of limits are not interfering in this case?

That help! Thank you! As i understand you correctly if i close limits for sensor i need to create new limits for every channel?

Yes, in the sensor settings you can choose the option "Only use the limits in the settings of the percentage channels" and then set the limits for each channel in the channel settings.
