When Operations Sentinel receives a response on its periodic spo_ping interface, it generates a message to report that success. Included in the message is a report of the success as well as the round-trip time in milliseconds for the ping operation and the hop count. These messages occur approximately once every 15 seconds.
If no response is received, a message is generated to report that failure. Operations Sentinel makes three successive attempts, approximately 6 seconds apart, to get a response from a spo_ping target. It generates a failure message for each failed attempt. After it detects the third failure, it marks the connection as failed.
Note: You cannot use PASSWORD and COMMAND actions in a pattern that matches a spo_ping message, since SP-AMS does not have a connection to the host.
Text of Successful spo_ping Message
The text of a successful spo_ping message is
Single Point ANSI X3.64 spo_ping OK RTT:tttt HOPS:nn
where:
tttt
is the round-trip time in milliseconds it took for Operations Sentinel to receive a response to the ping operation.
nn
is the number of hops it took to send and receive the response to the ping.
SP-AMS should receive one of these messages approximately every 15 seconds.
Text of Failed spo_ping Message
The text of a failed spo_ping message is
Single Point ANSI X3.64 spo_ping FAIL
When a failed spo_ping operation occurs. Operations Sentinel receives three successive messages, approximately 6 seconds apart.
