It's recommended to use a StatefulSet to load test a scrape based Prometheus backend. To scale up and down load simply increase the replicas up and down as desired.
Here's an example StatefulSet configuration that adds Prometheus scrape annotations:
apiVersion: apps/v1
kind: StatefulSet
metadata:
annotations:
labels:
app: promremotebench
name: promremotebench
namespace: default
spec:
replicas: 1
selector:
matchLabels:
app: promremotebench
serviceName: promremotebench
template:
metadata:
annotations:
prometheus.io/port: "4242"
prometheus.io/scrape: "true"
labels:
app: promremotebench
spec:
containers:
- env:
- name: PROMREMOTEBENCH_SCRAPE_SERVER
value: 0.0.0.0:4242
- name: PROMREMOTEBENCH_NUM_HOSTS
value: "500"
- name: PROMREMOTEBENCH_INTERVAL
value: "10"
- name: PROMREMOTEBENCH_BATCH
value: "128"
- name: PROMREMOTEBENCH_LABELS_JSON_ENV
value: '{"generator":"PROMREMOTEBENCH_POD_NAME"}'
- name: PROMREMOTEBENCH_POD_NAME
valueFrom:
fieldRef:
apiVersion: v1
fieldPath: metadata.name
- name: PROMREMOTEBENCH_NEW_SERIES_PERCENTAGE
value: "0.005"
