Hello,
I would like to know how to use the "Disk Usage" threshold, which can be seen when going to the "Thresholds and Polling -> General Settings" section, in an alert.
Someone can help me ?
I made an post on this a while back I can't find but there is some complexity with this. There is also a feature request.
The alert scope you want is 'capacity forecasting'
The variables are called 'level1/2' or 'critical value / warning value' depending on which one your working with.
Those settings set up when a disk is shown as yellow and status = Warning, or Red and status = Critical globally. If you are creating disk alerts you may want to match the global settings with whatever you use in your alert settings.
Below is an example of one way you could set up your alert triggers. In general I typically an alert for a Warning condition with lower values and alert actions such as send a email and create low severity ticket.
Once I get the Warning alert finished make a copy of it and rename the new copy Critical Disk and the Critical alert will be a higher value.
I typically also include available space because some servers may have smaller or larger disks, but I don't want to alert if there is still available space like the 20GB shown below. Also include/exclude the hosts, as shown below because we alert differently for AIX.
My Critical alert below is set for 95% so in my installation I match the Orion General Thresholds to match the alert that covers most of the nodes.
Here is an example of the variable you may want to use in an alert notification. This might save you some time trying to figure out which ones you need.
Server disk space has on ${N=SwisEntity;M=Node.DisplayName}, Volume ${N=SwisEntity;M=Caption} has reached or exceeded 95% of utilization and there is less than 20GB space left on a ${N=SwisEntity;M=CustomProperties.Device_Type} node. Remaining Disk Space is ${N=SwisEntity;M=VolumePercentAvailable}, Total Volume Size is ${N=SwisEntity;M=VolumeSize}, Available Space is ${N=SwisEntity;M=VolumeSpaceAvailable}. Instructions: Place Instructions Here ${N=Alerting;M=AlertName}
Thank you for your help
