Thanks for your replies. In iostat i could find the following fields

disk name of the disk

r/s reads per second

w/s writes per second

Kr/s kilobytes read per second

Kw/s kilobytes written per second

wait average number of transactions waiting for service (Q length)

actv average number of transactions actively

being serviced (removed from the

queue but not yet

completed)

%w percent of time there are transactions waiting

for service (queue non-empty)

%b percent of time the disk is busy (transactions

in progress)


can somebody explain what is the svc_t - service time and q-length are they inter-related?
thanks

NAME

       pmdabonding - Linux bonded interface performance metrics domain agent (PMDA)

DESCRIPTION

       pmdabonding is a Performance Metrics Domain Agent (PMDA) which exports metric values from bonded network interfaces in the Linux kernel.

INSTALLATION

       If you want access to the names and values for the bonding performance metrics, do the following as root:

	       # cd $PCP_PMDAS_DIR/bonding
	       # ./Install

       If you want to undo the installation, do the following as root:

	       # cd $PCP_PMDAS_DIR/bonding
	       # ./Remove

       pmdabonding is launched by pmcd(1) and should never be executed directly.  The Install and Remove scripts notify pmcd(1) when the agent is
       installed or removed.

FILES

       $PCP_PMDAS_DIR/bonding/Install
	   installation script for the pmdabonding agent

       $PCP_PMDAS_DIR/bonding/Remove
	   undo installation script for the pmdabonding agent

       $PCP_LOG_DIR/pmcd/bonding.log
	   default log file for error messages from pmdabonding

SEE ALSO

       pmcd(1) and ifenslave(8).
