Your Exinda 3062 performance is suboptimal because it has exceeded the appliance's capacity. You find that CPU usage often at 100%, Edge Cache is causing a Kernel dump event related to collectord, and Bridge PPS and Edge Cache are double the capacity of what the appliance can handle.
- See the High CPU Utilization Suggestions article
- Implement the ddos tcp ignore command to increase available resources for the TCP ignored and aborted connections
- Disable Edge Cache by navigating to Configuration > System > Optimization > Edge Cache. You can continue to enable Manage Optimization Services. Turning off Edge Cache will lower CPU utilization.
- Navigate to Configuration > Traffic Policies > Optimizer. Select the Optimizer tab. Change the Oversubscription management of the Virtual Circuit to Automatic for both Inbound and Outbound. This allows the VC to share bandwidth proportionally with other "Automatic" VCs.
- Balance the traffic among the bridges to prevent a scenario where only one bridge is handling most of the traffic.
- If the above steps do not resolve the capacity issue, please contact GFI Sales to find a model better suited for your needs. The path to fully solve capacity issues is to acquire a new box with upgraded capabilities. Capacity issues are not handled as an RMA since there are no hardware or software defects on the appliance.
Check to see if the CPU, Edge Cache, and TCP Health Charts, and Bridge PPS are operating below the device's capacity.
If the Exinda is instead experiencing hardware or software defects, contact Exinda Support to help diagnose and send the following:
- Sysdumps: Under Configuration > System Diagnostics > Diagnostics, click on Generate Diagnostics, wait for the Diagnostics to be generated and refresh the page after a few minutes for the new sysdumps, and click on the Sysdumps to download.
- PDF report: Under Monitor > Scheduled reports, add a new report with all the options selected for a period of the last 7 days [or last 24 hours if issue within this period]. After adding, click on the Adobe icon to download the PDF report. Please wait on the same page until the report is generated.
- Upload to GFI FTP Server: Please compress the above files into a single .zip file and upload it to the GFI FTP server. Once uploaded please share the filename so we can download it.
