perfSONAR User Q&A and Other Discussion

[Jeremy Palmer <>]

Is it possible to make PerfSonar Dashboard ignore negative latency numbers so 
they don't show up as CRITICAL/RED squares on the PerfSONAR Dashboard?
Our OWAMP dashboard is configured to return Critical status if latency is > 
60ms. However, some of our sites are very close to eachother (less then 0.5ms 
one-way) and due to NTP clock skew, they sometimes return negative results 
(example: -0.016ms). Unfortunately these negative numbers cause the dashboard to 
alarm Critical/red for that check. This confuses our TAC guys and can also mask 
real latency issues.
Any way to make the dashboard ignore negative latency numbers so they don't 
return CRITICAL status?
