TEST RESULTS OVER TIME 

Stats gathered currently (note, seeding hammers the server badly so data is gathered as a representative eyeball test level after seeding has completed when it has levelled out and is stable):
APPDEX average ( 0.85 or higher is the goal)
APPDEX worst / route
PASS %
CPU avg percentage during test phase not seeding
MEM avg representative during actual test phase
LOAD avg representative 5 minute load value during test (not super relevant but maybe in conjunction with other values a good representative)
RESTARTS number of times ayanova was restarted due to dotnet exit w error


Test parameters, user count only change between runs, 20 minutes each run. 5 minutes "soak" time between data generation and start of test run
./jmeter/bin/jmeter.bat -f -n -t stressdevops.jmx -l ./results/results.jtl -e -o ./results -JayServer=3312.onayanova.com -JaySeedLevel=large -JayUserCount=20 -JayDuration=1200 -JayProtocol=https


GOALS
Don't crash the server (no restarts of AyaNova)
Don't run out of memory
Average appdex of .85 or better
REasonable cpu overhead (which corelates to desired appdex around max )
True (test not seeding) pass rate of 98% or higher


All tests were on same droplet: 3312.onayanova.com in NYC1 data center - Ubuntu 22.04 x64
Sized it up and ran through each level of testing
Tests are a what I hope is a fairly representative simulation of users hitting it pretty hard in a real world manner (e.g. random brief pauses between page loads, not just serially hammering it in a machine like manner).
