Hi team, I have two queries as mentioned below:
*Query1:* I am using PrometheusReporter to expose metrics to Prometheus Server. What should be the minimum recommended scrape interval to be defined on Prometheus server? Is there any interval in which Flink reports metrics? *Query2:* Is there any way I can fetch the metrics of all vertices (including subtasks) of a job through a single Monitoring Rest API of Flink. As of now what I have tried is first finding the vertices and then querying individual vertex for metrics as below: *Step 1:* Finding jobId (http://<IP>:<Port>/jobs) *Step 2:* Finding vertices Id (http://<IP>:<Port>/jobs/<jobId>) *Step 3:* Finding aggregated metrics (including parallelism) of a vertex (http://<IP>:<Port>/jobs/<jobId>/vertices/<vertexId>/subtasks/metrics?get=<metric1>,<metric2>) So like wise I have to invoke multiple rest apis for each vertex id . Is there any optimised way to get metrics of all vertices? Thanks & Regards, Ashutosh
