Plot more metrics in real-time

[nakabonne]

It would be nice if it's able to press Ctrl-i to switch between charts.

• Plot 50th, 90th, 95th, and 99th percentiles percentiles chart #66
• Bytes In and Bytes Out
• Status Codes
• Histogram Histogram bar chart #63
• Workers running in concurrent

What do you think about we clicking on each option and showing them (changing the current line chart?)?

I wish we had tabs on termdash, but it doesn't have tabs unfortunately :(

[nakabonne]

@brenol Sorry, I completely missed your message. termdash is capable of switching dynamically the layouts like this.

[brenol]

@nakabonne no problem. I started work on percentiles and I think I'll be able to open a PR this weekend :)

That would help. I'm wondering if we can do that with Histogram which is commented out now.

Line 14 in ec2b6b4

// Histogram *vegeta.Histogram `json:"buckets,omitempty"`

I'll take a look at histogram. However, vegeta.Metrics calculating quantiles is actually okay (??).

This is how it looks (wip) [p50, p75, p90, p95 & p99]. My test server is running Sleep(rand.Intn(1000 * Millisecond)):

I'm not done yet, as I want to show legend like in this issue mum4k/termdash#188

Just didn't get the time, but I'll finish this one soon and I'll try to make it as reusable as possible so we can support bytes in/bytes out & status codes as well.

Closing because I opened each issue individually; label:new-chart
