This report shows the number of VMware disk commands that were aborted, whether through excessively high storage demands or when storage is not properly configured to handle the I/O load. Improper storage configurations are major factor in VMware performance.
Note: This metric is not available if the virtual machine is using an NFS (network file system) datastore.
When storage devices are overloaded, operation time-outs can cause commands already issued to disk to be aborted. This can lead to serious VMware application-level performance problems. If a storage device is experiencing VM disk command aborts, the cause must be identified and corrected immediately.
See the Oracle VMware and SQL Server VMware Tips on Overloaded Storage.
Confio IgniteVM helps identify the impact of aborted disk commands for sites running Oracle on VMware, SQL Server on VMware, and other virtual databases. IgniteVM helps DBAs maintain performance and availability on virtual servers. IgniteVM is the only virtualization-aware database monitoring solution.
