Some examples of #PromQL queries

• Get the average CPU usage for all pods:

avg(container_cpu_usage_seconds_total{container=~".*"})

• Get the number of requests per second to the web service:

rate(http_request_total{service="web"})

• Get the 95th percentile of response times for the web service:

quantile(0.95, http_request_duration_seconds{service="web"})

• Get the number of errors per second for the database:

rate(database_errors_total{database="mysql"})

• Get the total amount of memory used by all pods:

sum(container_memory_usage_bytes{container=~".*"})

• Get the percentage of requests that took longer than 100ms to respond

(rate(http_request_duration_seconds{service="web"} > 0.1) / rate(http_request_total{service="web"})) * 100
