- Capture health check
The maintenance utility monitors the capture processes to determine whether they are in good health.
- Capture restart
According to a predefined schedule, the maintenance utility stops the capture processes, clears the runtime statistics that are collected, then restarts the processes.
- Log file location
For the HCL DiscoverNetwork Capture Application, log files are located in the following directories:
- Statistics logging
Statistics log files are generated in the DNCA log directory.
- Time synchronization
The utility synchronizes the current date and time with the current date and time of a HCL Discover server that is running the Discover Transport Service. The maintenance log file contains the output of the time synchronization task if it is enabled.
- Manual configuration
You can manually configure the maintenance utility by editing the configuration file for the utility.
- Protecting memcached data from unauthorized access
An attacker with access to the memcached port (port 11211
by default) on the DNCA, can read memcached operational data, read TLS session state for any active sessions, and cause the denial of service by writing specially crafted data (or just clearing the cache).
