prom query again..

[mysterytree]

Hi @juliusv
I want to monitor the container memory used rate.
I write this query

sum(container_memory_usage_bytes{name!=""})by(name)/machine_memory_bytes 

And respones no date.
Maybe both

sum(container_memory_usage_bytes{name!=""})by(name)

and

machine_memory_bytes 

return a list.
So I have to write

sum(container_memory_usage_bytes{name!=""})by(name)/16829906944*100

I have two vm with same the memory
So it can works.
But if they are different ,what should I do ?

[roman-vynar]

sum(container_memory_usage_bytes{name!=""})by(name)/ on (LABEL) machine_memory_bytes
where LABEL is common label between those metrics, i.e. jobname or some host definition.

@roman-vynar where container_memory_usage_bytes metrics is coming from? I would like to have this metric too but could not find where I should scrape to get this metric.

@cemo cadvisor

@roman-vynar I am using https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus-kubernetes.yml but I could not be sure that this configuration contains scraping kubelets as well. Is there a part for kubelet inside it?

[roman-vynar]

@cemo We are not using Kubernetes, we run cadvisor standalone on each docker host.

[juliusv]

@cemo This part should be the one that scrapes the kubelets: https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus-kubernetes.yml#L50-L78
