Troubleshooting a slow probe system
If a probe is overloaded, consider whether any of the following affect the system. You can clear these one at a time to see if that resolves the system’s issue.
Although all of the settings discussed in this section are configured in Observer , they are saved to the probe.
A scheduled capture can be causing a system slow down. Determine if any scheduled capture is occurring. On the Home tab, in the Capture group, click Live > Packet Capture and then Settings > Schedule.
Some extra processing happens when you have triggers and alarms configured. Determine what alarms are enabled by clicking the Alarm Settings button in the lower left.
Are you running real-time Expert Analysis? Observer requires some processing resources to get through the data, which could be a lot of data. Real-time expert processes data as it is received. This requires continuous processing of incoming data while the real-time expert is running.
Are you collecting combined station statistics or protocol distribution summary for your network? If so, these could be causing the system to slow down. To determine if you are, click the File tab, and click Options > General Options. Scroll to Startup and runtime settings and clear these settings, if necessary:
Collect combined station statistics at all times
Collect protocol distribution for the whole network
Are you collecting network trending statistics? If so, is the sampling divider less than 10? If so, increase the sampling divider to 10 or greater. To determine your sampling divider, on the Home tab, in the Capture group, click Network Trending > Network Trending. Then click Settings > General tab. In the Collection Settings section, change the sampling divider.
