Working with the History and Peak Value Files

The 61000/41000 Security System periodically saves historical system performance and peak value data. New history files are created based on a predefined interval (Default = every 4 hours). New peak value files are created whenever a new peak value is detected. These files are located at /var/log/asgstats.

The system saves these files until a predefined maximum number of files is reached, after which files are deleted on an oldest first basis. You can also delete all history and peak value files manually.

System performance data includes these parameters:

• Throughput
• Packet rate
• Connection rate
• Concurrent connections
• Acceleration load
• Firewall load
• Memory consumption

You can collect the data contained in the historical peak value files and save them into two comma-separated-value text files. There is one combined file for historical system performance data and another for peak values. You can export these files and analyze them in a spreadsheet or statistical analysis application. The combined files are saved at $FWDIR/conf/asgpeaks.conf.

To create the combined text files, run:

> asg perf -k --last

> asg perf -k --hist

To delete the history and peak value files, run:

> asg perf -k -e
