The Engine charts show performance details of
NetMon's packet-processing component (the
Engine).

Packet Processing Statistics | Displays number of packets per second processed and filtered out. Statistics include: - Internal PCAP Failed. The packets per second that the PCAP (packet capturing) component failed to send to the packet routing components.
- Internal Worker Failed. The packets per second that the packet processor (the Worker) failed to process.
- Filtered Out. The packets per second that NetMon filtered out. NetMon filters out and discards packets based on IP filter and application filter configuration settings.
- Internal Capture Failed. The packets per second that the NetMon packet routing components failed to send to the ixEngine worker components.
- Processed. The packets per second that NetMon successfully processed.

| Engine Queue Usage | Displays the percentage usage of queue capacity. Queue sizes are Small (S), Medium (M), and Large (L). |
Sessions Started | Displays the number of client-server sessions started per second on the network. |
Sessions Active | Displays total number of currently active sessions across the network. |
Packet Deviance Statistics | Displays the average number of CPU cycles it takes to process a packet on the network. "Average Deviant Packet Time" represents the CPU cycles necessary to process "deviant" packets (any that are more than 500 times more CPU-intensive than "average" packets). It is common at startup to witness deviance, as an average has yet to be established. |
Packet Thread Distribution | Displays the number of packets processed per engine thread. |
Failure Thread Distribution | Displays the number of failed packets per engine thread. |
