Hi Mike,

 

I cannot give you any advice on this issue, but I am still curious,

 

Would you like negative values to be colored green – or perhaps some other color? Having negative latency is maybe a situation you would like to be aware of.

 

Can you share the URL to your MaDDash?

 

Best,

Rade

Subject: [perfsonar-user] Negative Latency Times on MaDDash

 

I know that this issue has been raised before, but perhaps someone has a solution to it. For some reason the latency times between several of the nodes in my mesh are negative. I've been told before that this is likely due to the close proximity of the nodes in the mesh (most are less than a mile apart). This wouldn't really be a problem except for the fact these negative times show up red in the MaDDash latency grid. The legend states that only time of 10ms and greater will have the color red, but clearly the negative values are showing up red as well. Here is a screenshot of my latency grid on MaDDash:

Has anyone found a solution to this annoying problem? I would appreciate any help.

Thanks,

Mike Reece
