No its a custom in-house developed script (Its actually a WAN link latency check, not bandwidth)

The issue is when there is an outage then the client is expecting to see a gap in the graph - but currently they see the latency stay at a constant number - so it looks like there were no outages when infact the entire line was dead

This is an example-
The graph looks fine but actually the check was in critical failure between those two red marks

Its used to look like this-
Where the gaps were easy to spot


Don't get me wrong - its a really cool feature, something we will definitely be trying to implement - but if there is no recording system keep track of what the numbers actually are it cant just "have a guess"

Can it be turned off for active checks but not passive ones?

There is not a way to turn it off and the drawing of the line from the last performance data point received to the current one has been there for a long time.

The Used to look graph is typically what a graph looks like when the processes that gather the performance data are not running so it does not plot any data at all. Not even zero.

One suggestion is to edit the plugin and it detects that the line is down, have it output a 0 for the performance data.
