Troubleshoot Errors: VMware ESX/ESXi – Virtual Machine Filesystem High Disk Utilization


The virtual machine filesystem on host is now 95.04 percent used, as of 2015-09-29 08:21:02 PDT

This error scenario is common when monitoring VMware ESX and/or ESXi hosts. These type of errors are easy to diagnose for they generate a single alert per incident.

The resolution is as straightforward as to clean up disk space on the disk volume in question. If this issue is not addressed, eventually the system will crash.

Deploying Intelligent Monitoring on ESX/ESXi hosts provides a lot of detailed information about both the ESX/ESXi host as well as the guests running on the host. This information includes ESX/ESXi host CPU utilization, guest logical volume usage, ESX hardware health (including cooling fans, disk drives, and power supplies), and network interface statistics – just to name a few metrics available.

VMware ESX/ESXi hosts will generated alerts for errors and critical events so that your IT team can be proactive. You IT staff has access to both current and historical performance data and alerts as with any other monitored device.
