I like it. And dont be discouraged by anyone who says, "but Jmeter can do X".
More fundamentally, the load testing space feelsnlong overdue for a shakeup. I feel its like network tracing was before Wireshark/ethereal showed up. You had ludicrously pricey fixed tools like Sniffer, weird point tools like ms netmon, and then one day wireshark showed up and totally upended the market. Today i see similar on testing, i mean ixia, landslide, jmeter...time for a revolution?
For the things that I've work on, in addition to regular health checks, we always write custom load generators that _really_ understand the domain and were configurable to realistic traffic levels. You can always leave them running, instrument them with metrics, and plug it into your alerting infrastructure so that you can page based on "realistic" client-side observable behavior. It's a super useful addition to the occasional time you need to do a performance/scale test.
Is there a generic load tester that allows you to define enough calling information about the APIs to get the same level of value out that I described?
Your mac download appears to be broken. Downloads as loadjitsu-mac-0.0.2 but my Mac doesn't know what to do with it. Tried appending .dmg and .zip with no luck. Excited to try out the app when it's fixed :)
Mac download is not a .dmg, cannot open w/o adjustment.
Download for mac = Access Denied aws S3 page.
Should’ve called it jjitsu
JMeter has literally hundreds more features than this. This tool (apart from the non-free licence) seems more similar to `ab` and the dozens other http benchmarking tools (like siege, wrk, httperf, and others I haven't tried), with an added basic GUI.
The last time I used JMeter to load test a site, I simulated many users: each thread logged into the site with its own account, selected a course (it was a LMS, Learning Management System), then opened a quiz, randomly answered all the questions, etc. Various metrics and graphs (e.g. RPS, 1%-quantiles of latency...) were used to estimate the maximal capacity of the web site. I also had a JMeter plugin that extracted perf data from the HTML responses. JMeter is a complex beast, and I'm not fan of its XML config and Java/Beanshell scripts... but I don't see this as a replacement in any way.
