Multi-Port Monitor consists of multiple processes, or daemons, that capture packets, calculate metrics, inspect packets, and perform automatic system maintenance. The Process Information section provides frequently updated status information for the following processes:
The packet-capture daemon. Its log file name is nqnapacapd.log.
Tip: To reset port statistics, restart the nqcapd process.
The metric-computation engine is roughly equivalent to the Metric Compute Module on the CA Application Delivery Analysis single-port monitor. Its log file name is nqMetricReader.log.
The inspector daemon is roughly equivalent to the SA Monitor service on a single-port monitor. Its log file name is nqInspectorAgentd.log.
The watchdog process monitors the status of other processes and restarts them if necessary. Its log file name is nqwatchdog.log.
The system-maintenance daemon. Its log file name is nqmaintd.log.
The Data Transfer Manager process receives and transfers data from a Cisco Wide-Area Application Services deployment. This process has a status of Stopped when Multi-Port Monitor is not configured as a CA Application Delivery Analysis monitoring device. After you configure the monitoring device, this process is always running, even if it is not used. The log file name is saDataTransferManager.log.
Tip: You can also see the status of these processes on the Process Status page at Administration, Processes.
