Nonlinear Workload - Decimal Ramp Rate

[Zakaria-Kofiro]

Nonlinear Workload - Decimal Ramp Rate
An update to the nonlinear workload model to allow for decimal ramp rates, allowing for more granularity in both the ramp as well as the target steady state concurrent users. This involved the following changes:

• Adding a new field to the DB, target_rate to take in decimal ramp rate and save ramp rate per project
• Limit the ramp rate between 0.001 and 1.000 and pass the ramp rate directly to agents. This is different from before where the overall ramp rate was divided amongst the number of agents, allowing individual agents to ramp to any rate with staggered start. Now each agent is an isolated non-linear ramp ramping anywhere between 0.001 and 1.000 users/sec.
• Each agent will now start ramping nonlinear ramp immediately, they no longer have a staggered start. This will allow the overall ramp to hit its steady state at the correct time when before it was delayed by the staggered start of agents.
• Updated UI to accommodate the changes including limiting ramp rate entry (0-1 user/sec) and QOL changes to Job Details

Example:

• Agent Ramp Rate: 0.61 user/sec
• Total Ramp Rate: 4.27 users/sec
• Number of Agents: 7
• Ramp Time: 13 min
• User Duration: 13 min

Expected Steady State Concurrent Users: Ramp Time (secs) x Total Ramp Rate = ~3325 users (475 users per agent)
