3.2.1.8 Enhancements to pmgrd Daemon and collect Utility

Patches in this kit provide enhancements to the performance manager metrics server daemon,

pmgrd, and the collect utility.

3.2.1.8.1 Performance Manager Metrics Server Daemon (pmgrd)

The following features have been added to pmgrd:

• Support for monitoring the disk I/O rates.

Enables pmgrd to provide details on disk I/O rates, such as the average number of bytes

transferred per second and the average number of transfers completed per second over the

past 1 minute, 5 minutes, 30 minutes, and 60 minutes.

• Support for monitoring the AdvFS statistics.

Enables pmgrd to provide the following types of details on AdvFS file systems:

— The domain name

— The fileset name

— Number of files and blocks

— Soft and hard limits of files

— Soft and hard limits of blocks

— The status of user and group quotas

— Grace time and fileset clone information

It can also provide AdvFS volume details such as available blocks, percentage of volume

used, I/O consolidation mode, and the number of read/write blocks. The new MIB file

pmAdvfs.mib has been added to provide these statistics.

The collect utility displays these new AdvFS statistics. (See “New Features Added to

collect Utility”).

As a result of the improvements made to pmgrd, we recommend that you use the SysMan Menu

to manage AdvFS file systems rather than the dtadvfs graphical user interface and the advfsd

daemon. To use SysMan Menu, select Storage - File System Management Utilities - Advanced

File System (AdvFS) Utilities. You can also enter the following command:

# sysman advfs
