I/O activity charts

Admin panel

The Read and Write charts show the history of the cluster I/O activity as the speed of read and write I/O operations in megabytes per second, and the number of read and write I/O operations per second (IOPS). For example:

Command-line interface

Use the following command:

vstorage -c <cluster_name> top

For example, to view the I/O activity in the cluster cluster1, take a look at this line from the command output:

IO:       read 30.5MB/s (523ops/s), write  108MB/s (5.9Kop/s)

IO

Disk I/O activity in the cluster:

• Speed of read and write I/O operations, in bytes per second
• Number of read and write I/O operations per second
