Next to triggering an alarm when storage utilization reaches a certain threshold, I am looking for a solution to also trigger an alarm when the amount of data written in a certain time frame is more than X GB, for example more than 100 GB in the last two hours (sliding window).
Another idea is to also trigger an alarm when no data was written in a certain time frame.
Is there a simple way to trigger those alarms using standard DataMiner alarm template functionality?
Another option, that can also be used for storage clusters is to create an aggregation rule on a view containing the Microsoft or Linux elements. For Microsoft platform elements, you can aggregate the free space of either a specific disk or all disks. By running the aggregation every 2 hours and adding a rate alarm for a difference of 100GB, you can get an alarm if over 100GB was written. Similarly, you can set up an alarm for no data or, as there is likely to be some disk activity e.g. less then 10MB written to disk.
