Flink 指标的 Prometheus 查询示例

Question

Need a help. Does any one of you have an example Prometheus query for following metrics. These are gaugue metrics, I am not sure, which operator to use for these metrics.

flink_taskmanager_job_task_numRecordsInPerSecond flink_jobmanager_job_fullRestarts/flink_jobmanager_job_fullRestarts flink_taskmanager_job_task_isBackPressured flink_jobmanager_job_numberOfFailedCheckpoints flink_jobmanager_job_lastCheckpointDuration

thanks.

Answer 1

I think it would be good if you look some official Prometheus APIexamples and Grafanadocs if you use it.

Here the query that I use:

sum by(job_name)(flink_jobmanager_job_totalNumberOfCheckpoints{job_name=~"myJobName_.+"})
