So do we have any performance monitoring tool to find when it goes high and get reduced to low ?
From what you describe I would presume that the /drbackup FS is used for a backup which is copied after completion to another storage system (such as TSM) and then deletet from the /drbackup FS.

So you want to know what is going on in the FS when it gets full and at what time this happens.
You might start by configuring NMON to monitor the Filesystems, write the data into a file and use the NMON-Analyser to convert the data into an Excel sheet. Choose the monitoring intervall according to the time needed to register the backup process. For details about NMON read the man page and look into the information in the NMON wiki. The NMON output should give you a good picture of when this process takes place and to what extent the FS gets filled.

envmond(8)						      System Manager's Manual							envmond(8)

NAME

       envmond - Environmental Monitoring daemon

SYNOPSIS

       /usr/sbin/envmond

DESCRIPTION

       Environmental  Monitoring  provides  a  means of detecting system threshold conditions, that if exceeded, could result in a loss of data or
       damage to the system itself.  Using the envmond daemon, thresholds levels can be checked and corrective action can ensue before any  damage
       occurs.

       The envmond daemon performs the following: Queries the system for exceeded threshold levels.  Broadcasts a message to users warning of high
       threshold conditions or fan failure, and suggests corrective action.  Sends a message to users when a high temperature condition  has  been
       resolved.  Notifies all users that an orderly shutdown is to be initiated if recovery is not possible.

       To  enable  Environmental  Monitoring, the envmond daemon must be started during the system boot, but after the eSNMP and Server System MIB
       agents have started.  Before starting Environmental Monitoring, a system check is performed.  If the system hardware does not support Envi-
       ronmental Monitoring, the envmond daemon and Server System MIB are not started.

       You can customize, start, and stop the envmond daemon using the envconfig utility.  For more information, see the envconfig reference page.

FILES

       A database that contains the values of the Environmental Monitoring variables.
