DESCRIPTION

The gstat utility can be used to monitor I/O transactions of geom(4) devices.

The options are as follows:

  Only display providers that are at least 0.1% busy.
-b
  Batch mode. Collect numbers, print and exit. Default if stdout is not a tty.

-d
  Enable display of statistics for delete ( BIO_DELETE) operations.

-o
  Enable display of statistics for other operations ( BIO_FLUSH).
-s
  Enable blocks' size statistics.
-I interval
  Refresh the gstat display every interval microseconds. Adding a suffix of s, ms, or us (the default) indicates that the update interval is specified in seconds, milliseconds, or microseconds, respectively.
-p
  Only display physical providers (those with rank of 1).
