jmxtrans docker-compose run

The following is a simple demo, using jmxtrans be jmx indicators of treatment, the use of docker-compose the project running
simultaneously writing data to the graphite

Configuration instructions

• jmx service app
  is mainly configured by jmx start running, specific reference docker-entrypiont.sh
• jmxtrans
  by docker run, mainly Profile jmxtrans.json added several inquiries by GraphiteWriter while
  writing data to the Graphite
  illustrate several parameters, if you read the official wiki and code will find that there are several parameters that must be write, but it is not very clear wiki
  mainly rootPrefix, flushStrategy,typeNames

Start && test

• start up

 

docker-compose up -d

• effect

 

Explanation

The above is a simple docker-compose run, in fact, we can expand, add more jmx indicators for operation mode kuberntes, refer to a similar manner, but
we can use localhost to run multiple containers in the pod resolved, it is quite easy
