Ping latency

Question

ipMonitor 8.5

I want to trigger an alert when the latency exceeds a certain threshold.  Am I looking right over it?  The ping monitor only fails when it gets no response.

I think I'm just going to try to create a little script that returns an error code of the average is > 100ms or so and run it as external process

Unless someone already has something like that handy...

Good point, wildblue.  I'm seeing the same issue in 9.0.1.  The dashboard's 'Top 10 Devices by Ping' shows each device's response time but you can't seem to set any thresholding or alarms on response time (or latency).  You could have a device that is returning 800ms ping responses but you wouldn't know it unless you were glancing at the dashboard.  It'll always be green so you have to be vigilant to spot the excessive times.

Yes. To some degree this can be 
accomplished.   A “ping” monitor can be adjusted to fail at any time increment 
you choose.   This is done by making a combination of adjustments in the 
properties of the monitor itself.   In the “Timing” parameters, you will want to 
adjust the “Maximum Test Duration” from its default value of 300 seconds to 
something more aggressive say in the 10 - 30 seconds range.  Next you should 
look at the Notification control section and specifically at the value set for 
“Accumulated Failures per Alert”.   This value is set to “3” by default, 
however, if you wish hasten the alert notification process you will want to set 
this to a value of “1”.  This will cause the test to occur just once in the 
“Warn” state and then drop to a fail state.   Please note that ipMonitor is only 
able to trigger alerts from a “failed” state and can never do so from a “Warn” 
state.
 
I hope this is 
helpful.
