However, my intent was for per-VM breakdowns, and I updated my first sentence to reflect that. Update: Dan in the comments does point out that ‘df’ is another utility that will show you your datastore usage. Less than this, and you might experience problems when a snapshot is not deleted. When using this metric, verify that you have at least 20 of free storage. For virtual machines with thin disks, the actual storage use value might be less than the size of the. When the virtual machine is running, the used storage space also includes swap files. When using fully allocated - or thick-provisioned - virtual disks, calculate the required capacity for each VM, and map those VMs to VMware datastores. Use this metric to know the percentage of storage space being used on the datastore. Storage Usage shows how much datastore space is occupied by virtual machine files, including configuration and log files, snapshots, virtual disks, and so on. When designing storage for vSphere, figure out your VM and application requirements first. But for quick & dirty information this way is pretty handy. This metric shows the amount of storage that is being used on the datastore. Also keep in mind that this is only useful on ESX where you have a command line, so if you are running ESXi, or thinking about it, a PowerCLI or other API-based solution would probably be better. Keep in mind that you’re seeing the disk space used by everything in that folder, including swap files (.vswp), snapshots, etc. If you want to sort by space used, use the -n parameter, which tells it to treat the sort fields as numbers: # du -s /vmfs/volumes/netapp-*/* | sort -n The -k parameter tells it what field to sort on. A refresh will update the correct storage space temporarily before the incorrect space is. The ‘-t’ parameter changes how sort detects fields, specifically that the field delimiter is a different character than a tab (t). When logged directly onto the ESXi via Host client or CLI the correct space is reported however when logged into the vCenter Server using vSphere Client the displayed values for the free space & used space may be different or change randomly. Use the ‘sort’ command: # du -s /vmfs/volumes/netapp-*/* | sort -k 5 -t '/' If you’d like the output with human-readable numbers, try using ‘-h’ with du: # du -sh /vmfs/volumes/netapp-*/*Ģ6G /vmfs/volumes/netapp-linux-1/Ĥ0G /vmfs/volumes/netapp-linux-1/Ĥ8G /vmfs/volumes/netapp-linux-2/Ĥ7G /vmfs/volumes/netapp-linux-2/Ħ7G /vmfs/volumes/netapp-linux-3/ Want to find out how much space is being consumed in your datastores, and by what? You can do this from the VMware ESX CLI using the ‘du’ command.įor example, if you have a set of datastores named with the prefix “netapp-” you can display the disk usage for all of the virtual machines in them with: # du -s /vmfs/volumes/netapp-*/*Ģ6214528 /vmfs/volumes/netapp-linux-1/Ĥ0952192 /vmfs/volumes/netapp-linux-1/Ĥ9340800 /vmfs/volumes/netapp-linux-2/Ĥ8292224 /vmfs/volumes/netapp-linux-2/Ħ9263744 /vmfs/volumes/netapp-linux-3/
