Chapter 2: Management and Maintenance 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. Note: The Clavister Pinpoint product The Clavister Pinpoint product is a separate, proprietary software monitoring product which is used with some older versions of cOS Core. In the current version of cOS Core, the Pinpoint product's functionality is now built into the Clavister InControl product. 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. 82
Chapter 2: Management and Maintenance 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. TCP SYN - Total number of TCP connections in the SYN phase. TCP FIN - Total number of TCP connections in the FIN phase. Other - Total number of other connections types such as IPsec. TCP Buffer Statistics Total small receive window usage - The number of small TCP receive windows currently being used. Total large receive window usage - The number of large TCP receive windows currently being used. Total small send window usage - The number of small TCP send windows currently being used. Total large send window usage - The number of large TCP send windows currently being used. Rule Usage Statistics Each of the rules in a rule set has a counter associated with it which has the same name as the rule type. These counters indicates the number of matches that have taken place for each rule. The rule sets that exist are: • IP Rules • PBR Rules • DHCP Rules • User-authentication rules Interface/VLAN/VPN Statistics Rx/Tx Ring counters - Some drivers support plotting of FIFO-errors, saturation, flooding and other values depending on the driver. Pps counters – The number of packets received, sent and summed together. Bbs – The number of bits received, sent and summed together. Drops – The number of packets received by this interface that were dropped due to rule set 83
