2. Quick Start

Step 1: initialize users and courses

nohup python -m app.utils.data_sync_init &

Step 2: start experiment

nohup locust --config=app/locust.conf &

Step 3: restart deployments and statefulsets

kubectl rollout restart deploy -n alms
kubectl rollout restart statefulset -n alms

3. Configuration

The experiment is separated into 14 days. The first two days are considered as the first stage and the other days are considered as the second stage. We use corresponding weights for different days and stages. So users should change weights and tasks in InstructorUser and StudentUser for different days of workload. To do this, you can simply modify EXPT_CONFIG and WORKLOAD_FILE in locustfile.py.

The desired configuration is:

Week	Monday	Tuesday	Wednesday	Thursday	Friday	Saturday	Sunday
1	DAY_1	DAY_2	DAY_OTHER	DAY_OTHER	DAY_OTHER	DAY_OTHER	DAY_OTHER
2	DAY_OTHER	DAY_OTHER	DAY_OTHER	DAY_OTHER	DAY_OTHER	DAY_OTHER	DAY_OTHER
