Is there a way to change the colour of a link on a map if the link uitlisation goes above certain thresholds ?
No. What you're looking for is a feature found in Network Weathermap. If you would like to see this feature in a future version of Orion add your name this this Orion feature request.
We just had a similar discussion here at the NOC. I would LOVE to have a map that displays the links between the sites and then turn red when there is an issue. Want to get really crazy? Imagine being able to mouse over the links and have a pop up appear with teh current stats for that connection... I would have no clue how to do this, but man it would be cool if it was an option.
You could add labels the the links and they will dynamically display the input and output utilization. Just make sure the links are connected to the interfaces you want and add these labels to the line or interface.
When ever the page refreshes you will get the current values.
In Utilization - ${InPercentUtil}
Out Utilaztion - ${OutPercentUtil}
You may have already known this but just in case.
