I have had a server crash recently because of the disk space.
Here is what I have: a Hyper-V 2012 server with 1 win 2012 image physical disk is 500GB server uses 800GB
It was OK for half a year but recently users started to upload all sort of data and 3 of my local drive got nearly 90% full. It this time the page file got bigger and the server went pause:critical disk space mode
I have now started to monitor the disk space on the hyper-v, image disks and the pagefile through powershell.
Would someone give some explanation what do I need to check from these csv log files?
I know this is weak explanation but I am a newbie and I am learning what to do. My aim is to prevent another crash by monitoring the usage and when it gets 90% of the usage I would alert users to act. This is a temporary solution for school time and I will 'reformat' or buy new disks to be able to cope with the load. However I would like to know how much I need to buy and what is the dynamic of usage of the school.
Please feel free to ask specific questions and I will dig out to make the question more precise. I also keen to learn to monitor page file usage which is auto setup by the server at this point.
Any hint or direction would greatly appreciate. (I inherited this server so I need to know what information to gather to get the full picture).
