2.4. Monitoring
The real-time performance of cOS Core can be monitored in a number of ways. They are:
• Using the real-time monitoring functionality in InControl.
• cOS Core real-time monitor alerts.
• The cOS Core link monitor.
• Monitoring through an SNMP client.
• Hardware monitoring for specific hardware models.
2.4.1. Real-time Monitoring Counters
cOS Core status and operational statistics are available to InControl for graphical display in a
variety of display formats. This is achieved by InControl routinely polling cOS Core to gather the
latest values of operational parameters. The following counters are available through this
feature:
Throughput Statistics
CPU – The percentage load on the gateway CPU.
Forwarded bps - The number of bits forwarded through the gateway per second.
Forwarded pps - The number of packets forwarded through the gateway per second.
Buf use – Percentage of gateway packet buffers used.
Conns – The number of connections opened via Allow or NAT rules. No connections are opened
for traffic allowed via FwdFast rules; such traffic is not included in this statistic.
Timers – The amount of timers used by the system.
Total mem usage – Percentage of the RAM memory that is currently being used.
Connection Rate Statistics
Conns opened per sec – The number of connections opened per second.
Conns closed per sec – The number of connections closed per second.
State Engine Statistics
ICMP Connections - Total number of ICMP connections.
UDP Connections - Total Number of UDP connections.
OPEN TCP - Total number of open TCP connections.
