AdvFS performance analysis commands Performance Manager provides the following AdvFS Performance Analysis scripts. To execute one, from the main window's Execute menu choose AdvFS Performance Analysis, then one of the following scripts:
This script determines if AdvFS performance can be improved by tuning some parameters. It looks at the percentage of volumes used and checks if there is any uneven usage. The balance command should be used to do any necessary balancing. The advfsdomain script can limit the number of volumes if necessary.
This script determines if the node has excessive AdvFS I/O problems. It looks at the number of maximum read/write blocks and the I/O write flush threshold value and checks if any of these parameters need tuning.
This script determines if AdvFS performance can be improved by tuning some parameters. It looks at the percentage of volumes used and the buffer cache hit ratio. It checks whether the log needs to be moved to a less used volume and whether the cache needs any tuning.
