Report of Growing Disk Space

Votes:

One of my VMs (VMware) is growing daily and reduce free space in the datastore, but I dont know which one it is. Is there a way to report this that I can identify the growing VM?

Couldn't you monitor the disk activity of the VMs and see which one goes crazy using our "VMWare Virtual Machine (SOAP)" sensor? The one with the most (or most consistent) disk activity is your guilty suspect :)

Hi Stephan,

with the "VMWare Virtual Machine (SOAP)" sensor I can´t monitor the disk activity. There is just the Datastore total Read and Write Latency to Monitor...

Hi Oliver,

Well I thought you could make use of the Disk Write channel somehow...the one with the most persistent (and possible highest) values is the one that fills up your disk. Other than that, there's only the VMware Datastore (SOAP) BETA sensor, but it won't be of use if you're using a single datastore for all VMs :/

Beside the mentioned options above, not really :( What about using SNMP Disk free sensors on the VMs?

I use the SNMP/WMI Disk Free Sensors all of my VMs, but how can I easy create a Report? I think I have to create a Report manuelly of all VMs that I want to Report, right? For >100VMs it takes a while ;-)

Just had a talk with our VMWare specialist Greg - have you had a look at the VCenter, especially the datastore overview? You can see all VMs and which ones use the most space of your datastore. Can you check that?

Yes I can see that in vCenter. But in this view I don´t have a reporting to see it over a specially time, it´s just a real-time view.

Meanwhile I build a new Report in PRTG, based on the sensor "wmidiskspacesensor" over all VMs. That Report Shows the free disk space over a definded time Frame. I think thats okay for me ;-)
