Overview of DNCA maintenance
The maintenance utility performs routine maintenance and logging tasks for Discover DNCA. You can use the utility to help maintain the ability of the DNCA to perform DNCA.
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 Unica Discover Network 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 Unica 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).
