Hi All,
I am trying to deploy a small application in a tomcat docker container and 
trying to monitor the container using Prometheus with the help of node 
exporter. But I am unable scrape metrics even though metrics is actually 
being pulled as i can see the output from browser or by using curl or wget 
command. 

Prometheus error : *context deadline exceeded*

Below is my Dockerfile :






*FROM jatayu99/my-tomcat:latestADD prometheus-jmx-config.yml 
/prometheus-jmx-config.ymlADD jmx_prometheus_javaagent-0.13.0.jar 
/jmx_prometheus_javaagent-0.13.0.jarCOPY ConferenceRoomCapstoneB35.war 
/usr/local/tomcat/webappsENV JAVA_OPTS="$JAVA_OPTS 
-javaagent:/jmx_prometheus_javaagent-0.13.0.jar=9830:/prometheus-jmx-config.yml"EXPOSE
 
9830 8080*

sarbajit@UBUNTU:~/expr/proj-ansi-roles$ cat roles/03-build-image/files/
prometheus-jmx-config.yml


*ssl: falselowercaseOutputName: falselowercaseOutputLabelNames: false*

But if I try to use port 8080 for jmx_prometheus_javaagent-0.13.0.jar then 
prometheus is able to pull the metrics but my application is not running in 
that scenario. 

Can anyone please help regarding this problem ??

Thanks & Regards,
Sarbajit Das
