The ICMP Echo operation measures end-to-end response time between a Cisco router and any devices using IP. Response time is computed by measuring the time taken between sending an ICMP Echo request message to the destination and receiving an ICMP Echo reply.
In the figure below ping is used by the ICMP Echo operation to measure the response time between the source IP SLAs device and the destination IP device. Many customers use IP SLAs ICMP-based operations, in-house ping testing, or ping-based dedicated probes for response time measurements.
You will the full guide to configure IP SLA ICMP Echo operation in the following link http://goo.gl/N0ihtv
Here is a sample of IP SLA ICMP Echo operation on Cisco router
ip sla 10 icmp-echo www.google.com source-ip 192.168.99.2 frequency 30 tag Egypt Office to Google exit ip sla schedule 10 life forever start-time now exit
Note: Frequency = Number of seconds between the IP SLAs operations. The default is 60.
Then we will use one of the following OIDs to create Active and Performance Custom SNMP Monitor
Label: iso.org.dod.internet.private.enterprises.cisco.ciscoMgmt.ciscoRttMonMIB.ciscoRttMonObjects.rttMonCtrl.rttMonLatestRttOperTable.rttMonLatestRttOperEntry.rttMonLatestRttOperCompletionTime Type: Gauge Access: Read Only Description: The completion time of the latest RTT operation successfully completed.
Label: iso.org.dod.internet.private.enterprises.cisco.ciscoMgmt.ciscoRttMonMIB.ciscoRttMonObjects.rttMonCtrl.rttMonLatestRttOperTable.rttMonLatestRttOperEntry.rttMonLatestRttOperSense Type: Enumeration Access: Read Only Description: A sense code for the completion status of the latest RTT operation.
I used the first OID (18.104.22.168.22.214.171.124.126.96.36.199.1.1) and the instance is 10. (instance = number of IP SLA operation/entry)
