The aws_sadmin service is responsible for processing all SNMP requests coming in from the various CA Technologies components and for the generation of SNMP traps. In addition to these functions, the aws_sadmin service also maintains the awsAdmin MIB and the associated awsAdmin agent. The awsAdmin MIB contains the following categories of information:
The statistical information is collected in the following different groups:
The maintenance of the statistical information within the awsAdmin MIB represents an appreciable amount of work for the aws_sadmin service. Up to 40 percent of the CPU time that the aws_sadmin process soends is updating all of these statistics.
As a performance-enhancing feature, the following environment variables have been added to control the collection of the statistical information within the awsAdmin MIB. These environment variables let you turn off the collection of any (all) statistics, resulting in the reduction in CPU (and increased performance) for the aws_sadmin service. The environment variables, with their possible values, are as follows:
AW_ADMIN_STAT_AGENT=ON/OFF AW_ADMIN_STAT_SNMP=ON/OFF/NOTOTAL AW_ADMIN_STAT_PERF=ON/OFF AW_ADMIN_STAT_SOURCE=ON/OFF
The default value for each variable is ON. If you want to change this value (to improve performance and reduce CPU overhead), define the environment variable within the agentworks.profile file in the root Agent Technology directory ($AGENTWORKS_DIR) of your zFS.
