Check permitted connections settings
At installation time, the DNCA sets the maximum permitted connections for each DNCA instance.
By default, these values are set as:
- Current connections max:
5000 - SYN/WAIT connections max:
1000
Note: The settings define the maximum permitted connections for each
DNCA instance. If the actual number of connections exceeds these values,
data can be lost. Any analysis of DNCA performance that is based on
the current state can be skewed depending on the volume of the non-captured
data. You must review these settings as soon as possible.
You can check the current state of these settings in the Statistics tab of the DNCA web console. For each DNCA instance, the statistics to compare are:
- Current
- Maximum
Current connectionsCurrent connections maxSYN/WAIT connectionsSYN/WAIT connections max
If either of the current metrics is near the corresponding maximum, you must consider raising the maximum for all affected DNCA instances. It ensures that data is effectively captured.
