Creating dashboards for stress testing in Prometheus involves utilizing Grafana to visualize the metrics collected by Prometheus. Grafana provides powerful dashboarding capabilities that allow you to display time-series data in a user-friendly format. To effectively monitor stress testing results, you might want to focus on key performance indicators such as response time, error rates, throughput, and system resource utilization.
Here's a basic example of how you can set up a Grafana dashboard for stress testing metrics collected by Prometheus:
{
"panels": [
{
"type": "graph",
"title": "HTTP Response Time",
"targets": [
{
"expr": "http_response_time_seconds{job=\"stress_test\"}",
"format": "time_series"
}
]
},
{
"type": "graph",
"title": "HTTP Error Rate",
"targets": [
{
"expr": "rate(http_requests_total{job=\"stress_test\", status!=\"200\"}[5m])",
"format": "time_series"
}
]
},
{
"type": "graph",
"title": "Throughput",
"targets": [
{
"expr": "rate(http_requests_total{job=\"stress_test\"}[5m])",
"format": "time_series"
}
]
},
{
"type": "graph",
"title": "CPU Usage",
"targets": [
{
"expr": "rate(process_cpu_seconds_total{job=\"stress_test\"}[5m])",
"format": "time_series"
}
]
},
{
"type": "graph",
"title": "Memory Usage",
"targets": [
{
"expr": "process_resident_memory_bytes{job=\"stress_test\"}",
"format": "time_series"
}
]
}
]
}
