instructions for integration with graphite

[cfregly]

are there instructions/examples on how to integrate servo with graphite?

i've got graphite setup per http://graphite.wikidot.com/installation, servo-graphite setup in my pom.xml file, my code instrumented with counters and such, and now i need to glue everything together.

i looked at the CloudWatchExample and i see the use of CloudWatchMetricObserver and PollCallable in a while(true) loop. i found the equivalent GraphiteMetricObserver, but still not clear on how to use it properly.

the following is the specific code that i'm trying to integrate:

pom.xml: https://github.com/cfregly/fluxcapacitor/blob/master/flux-core/pom.xml

instrumented code including DefaultMonitorRegistry.register() code:
https://github.com/cfregly/fluxcapacitor/blob/master/flux-edge/src/main/java/com/fluxcapacitor/edge/jersey/resources/EdgeResource.java

any tips would be very helpful.

thanks!

Chris,

The graphite module was contributed, we don't use it internally so I haven't used it that much. I tried it briefly when we got the submission and I may still have the basic example somewhere. I'll see if I can find it and check it in.

thanks, Brian! that would be very useful.

also, any info on the movement - and timing - of data would be useful.

this is the part I knew the least back at netflix as everything was wired up and ready by the time I got there... I just added more gauges/tracers/counters and they would magically show up.

I see that Hystrix has a custom observer that starts/stops/updates periodically. there's a lot if code there, as well, so it's hard to figure out what's going on, conceptually.

any info - and supporting examples - would be very helpful.

thanks!

I added a wiki page talking about graphite:

https://github.com/Netflix/servo/wiki/Publishing-to-Graphite

There is also a basic example app now:

https://github.com/Netflix/servo/blob/master/servo-example/src/main/java/com/netflix/servo/example/Main.java

You can run the example with:

./gradlew servo-example:run

By default it will log to local files. You can set some properties to enable reporting to graphite as well. When I get some time I'll add in the cloudwatch observer.
