How do I configure system logging?
The GPA 2G makes a great deal of logging information available to customers and their developers. Information from log files is always useful, never more so than when troubleshooting problems or changes to configurations. However, it is important to recognize that best practices, when using the GPA 2G, involves using a limited set of logging so that you can get the maximum performance from the device on a day-to-day basis.
Best practices are to use the GPA 2G's web interface (the “Gcom Management Console” or “GMC”) and set the following parameters [Note: Any or all of these may already have defaulted to these values, depending on the version of your software.]
- Click the "Applications" button. It is along the top on every screen and also in the middle of the work area when you first login.
- Click the "Load SSD" button. It is found along the left.
- Select the SSD that you intend to use.
- In the “Logging Options” section, set the Log Size to any amount (don't leave it blank). We suggest “10000”, which is 10MB, as being usually sufficient. Sizes much larger than that may affect performance.
- In the “Logging Options” section, set the Logging Options to “0x40”.
- In the “Logging Options” section, set the Log File to “ssd.log”.
- In the “Connection Name” section, select the “Log” linktext next to the “gpi.0” connection. Now “gpi.0” will appear up in the “Logging Options” section.
- Making sure that “gpi.0” is selected in the drop-down menu in the “Logging Options” section, set it's Log File to “gpi.log”.
- Making sure that “gpi.0” is selected in the drop-down menu in the “Logging Options” section, set it's Logging Options to “0x00” (zero).
- For each connection added thereafter, we suggest that you create a unique log file name. This is done similarly to Steps #7 and #8 above.
NOTE: Logs are also part of our dump file. Please see the next section titled “Troubleshooting and Dump Analysis” for more information.
