FXServer Performance Monitor

Collect and display (using D3.js) the performance of an FXServer.

Foot Note... ish

I wrote some code to help me build the heatmap for txAdmin, but it ended up acceptable so why not share it?!
I do not have the intention to update this repository... unless some people find it useful.
Also I am fully aware that I could use Grafana for this, but it wouldn't work for txAdmin.

Here's the grafana query:

histogram_quantile(0.95, sum(rate(tickTime_bucket[5m])) by (le))

Here is an example of the data we are scraping (svMain only):

# HELP tickTime Time spent on server ticks
# TYPE tickTime histogram
tickTime_count{name="svMain"} 873550
tickTime_sum{name="svMain"} 242.026000
tickTime_bucket{name="svMain",le="0.005000"} 873534
tickTime_bucket{name="svMain",le="0.010000"} 873538
tickTime_bucket{name="svMain",le="0.025000"} 873547
tickTime_bucket{name="svMain",le="0.050000"} 873548
tickTime_bucket{name="svMain",le="0.075000"} 873548
tickTime_bucket{name="svMain",le="0.100000"} 873548
tickTime_bucket{name="svMain",le="0.250000"} 873549
tickTime_bucket{name="svMain",le="0.500000"} 873550
tickTime_bucket{name="svMain",le="0.750000"} 873550
tickTime_bucket{name="svMain",le="1.000000"} 873550
tickTime_bucket{name="svMain",le="2.500000"} 873550
tickTime_bucket{name="svMain",le="5.000000"} 873550
tickTime_bucket{name="svMain",le="7.500000"} 873550
tickTime_bucket{name="svMain",le="10.000000"} 873550
tickTime_bucket{name="svMain",le="+Inf"} 873550
