- What's the prometheus version?
-> 2.15.2
- What's the scrape interval for this metric?
-> scrape_interval: 30m
- Does anything get logged by prometheus when you run this query and get
empty result? (e.g. "journalctl -eu prometheus" if running under systemd)
-> We run it in Kubernetes/Docker and the pod didn't generate logs when
I ran that query
- How many timeseries does this metric have? Does it make a difference if
you limit the query to a single TS, e.g.
elasticsearch_breakers_estimated_size{foo="bar"} ?
-> I'm not 100% to know how many time series it has. But Grafana says
we have 995 timeseries for that metric. I've tried to limit the most with
{es_master_node="true"} since we only have 2 masters and it still returns 0.
- What happens if you give an instant query with a range vector? This
should give you a matrix with the raw ingested data points
curl -g
'http://prometheus:9090/api/v1/query?query=elasticsearch_breakers_estimated_size_bytes[60m]'
-> This works; I see the raw data points.
