Connectivity Polling value defaults
By default, the Connectivity Polling values are set as follows:
PollingInterval = 240 seconds
Retries = 3
Timeout = 700 milliseconds = 0.7 seconds
The time out grows exponentially. Retries do not include the initial poll.
"----------- 3 retries -------------"
1 1 2 3 Timeout
.7 .7 1.4 2.8
Event Time (seconds) Description:
Connectivity poll takes place 0 Connectivity monitor takes place for system
Poll fails 0.7 Poll request timeout
Wait to poll again 58.6 Poll interval
Poll fails 0.7 Poll request timeout
Wait to poll again 58.6 Poll interval
Poll fails 1.4 Poll request timeout
Wait to poll again 58.6 Poll interval
Poll fails 2.8 Poll request timeout
Wait to poll again 58.6
Wait time is calculated as: (240 - .7 -1.4 - 2.8)/4 = 58.6
The wait time to poll again is calculated by Poll interval divided by number of retries set + 1.
The 240 Polling interval also includes ping time. However, if ping fails the first or second time and succeeds the third time, then Ping and SNMP Poll gets separated.
Example:
If Ping and SNMP Poll have total of 4 minutes Poll interval, and ping takes 2 minutes to respond, then SNMP Poll gets another 4 minutes by itself to get the data. Ping interval is half the amount of Polling interval, and ping timeouts do not have exponential growth.
TCP Poller three way handshake and FIN
TCP Poller does a full three way handshake and FIN for both discovery and polling as shown
by the below packet capture:
