risingstack / example-prometheus-nodejs Goto Github PK

Hello,

I have followed this and have NodeJS services exposing metrics at http://application:9083/metrics. Then I tried to use https://github.com/RisingStack/example-prometheus-nodejs/blob/master/grafana-dashboard.json to have graphs on Grafana, but it always shows blank ( No Data Points ). I feel its because the JSON is not covering more than one containers. I am having two containers running exposing metrics. Can someone suggest me the needed changes in the dashboard JSON please.

Thank you

Hello!

README contains the following:

Average Memory Usage
In Megabyte.

avg(nodejs_external_memory_bytes / 1024) by (service)

but nodejs_external_memory_bytes is size in bytes, therefore, we need use avg(nodejs_external_memory_bytes / 1024 / 1024) in order to show size in megabytes?

thanks for this example!

Why the memory calculation is only divided by 1024?
avg(nodejs_external_memory_bytes / 1024 ) by (service)
isn't it suppose to be:
avg(nodejs_external_memory_bytes / 1024 / 1024 ) by (service)

Existing docs appear to be missing a hyphen, causing a syntax error for users.

docker run -p 9090:9090 -v "$(pwd)/prometheus-data":/prometheus-data prom/prometheus -config.file=/prometheus-data/prometheus.yml

Should be:

docker run -p 9090:9090 -v "$(pwd)/prometheus-data":/prometheus-data prom/prometheus --config.file=/prometheus-data/prometheus.yml
