Activity Guages

Activity Gauge (1)

The percentage activity of the disk with the highest read/write rates.

Total

The total amount of free space that has been allocated to this disk.

Used (MB/GB)

The amount of disk space that is currently being used by this disk.

Used (%)

The amount of disk space that is currently being used by this disk, expressed as a percentage.

Data flows between the Memory panel and the Disk Activity panel

Disk I/O (Memory to Disk Activity)

The number of writes that the system makes to disk per second.

Disk I/O (Disk Activity to Memory)

The number of reads that the system makes from disk per second.

Blocked Process Alarm

The Blocked Processes button in the CPU panel shows the number of processes waiting on information to become available in memory.

Processes can also become blocked when they are waiting for:

  • disk I/O completion,
  • network I/O completion, or
  • a shared resource.

A high level of blocked processes may indicate an under-configured machine.

The type of alarm that is activated is determined by the number of blocked processes waiting on information.
