You will need to use a jitter operation to be able to use this object. Right now you're just doing an ICMP echo. For that, you could monitor rttMonLatestRttOperSense (126.96.36.199.188.8.131.52.184.108.40.206.1.2.111). If the value is something other than 1, then an error occurred (e.g. the round-trip response time was over the threshold, a timeout occurred, etc.).
