Hi Team,

We are doing the availability by sending the ping request. If the network has any fluctuation, the server/Network device is reported to be down. But the server is still available, it’s just that network is either down or it has fluctuation. If I go to uptime of the server, it is still 100%. But availability shows there is a drop. and this is impacting out SLA report. Could you please advise the best possible solution here to address this concern. thanks.

Do the ping requests time out completely, or do they just end up taking longer? The reason I ask, is because you may just be able to adjust your warning / critical thresholds if it's just a spike in latency.

Hi Kennedy,

It times out completely. please advise how can achieve 100% SLA. thanks.

100% server uptime doesn't necessarily mean it's been reachable on the network 100% of the time. If you feel these alerts stem from very short periods of high network latency, then definitely increase the warning and critical thresholds as rkennedy mentioned.

Hi Team,

Is there any way that I can get the information on "snmpEngineTime" of CISCO devices. I am also looking into editing the thresholds for the above said solution.

This plugin should work for snmpEngineTime:

Take not of this disclaimer "If you are using Cisco device please be aware of bug CSCeh49492, this will cause the snmpEngineTime to reset when sysUpTime will rollover. You can fix this with an IOS upgrade. "
