How to overlay a single static line against a timechart with multiple series without displaying each series as its own line?

[burras]

I have what should be a fairly simple timechart that I'm looking to do.

In our data, we have a field (util) that represents percent utilization at each of 3 sites. The sites are configured for (n+1) capacity so we want to have a manually entered capacity line at 66% (to show where if we had a site failure we'd still be able to maintain service on the 2 other sites). The general way I'd chart this without any sort of capacity line is |timechart max(util) by site. To add in the capacity line we'd generally do |eval capacity=66 |timechart max(util),capacity by site. However, when we do this, we end up with 3 separate capacity notations on the time chart: capacity:site1, capacity:site2, capacity:site3. And while we can pick all 3 as overlays so they show a single line, they still show as 3 separate notations in the legend.

What's the best way to overlay a single static line against a timechart with multiple series without showing as a per series result?

If the capacity=66 and max(util) are of same unit and can be plotted in same graph then can you try to add your eval command after timechart:

|timechart max(util) by site | eval capactity=66

That should keep one line of 66 on the timechart with all others the way you want.

Worked perfectly - thanks!

Hi burras,
I'm out so I cannot use my pc.
Every way, you can see the License usage Report to configure your overlay.
If you need Tomorrow morning I'll be again at work.
Bye.
