riemann-jmx's Introduction

riemann-jmx-clj

A Clojure clone of riemann-jmx.

Building

Use lein uberjar to build the standalone jar. You can download leiningen here.

Usage

Pass each of the riemann-jmx-config.yaml as command line options, e.g.:

java -jar riemann-jmx-clj-standalone.jar jvm-config-1.yaml jvm-config-2.yaml jvm-config-3.yaml

Note that passing multiple config files is the same as running a separate copy of riemann-jmx for each config file, except that it uses fewer resources.

Supports composite mbeans as well, unlike the current riemann-jmx.

See riemann-jmx.yaml.example for an example of how to write a configuration file.

riemann-jmx's Issues

IP resolution error in hostname is a number

We have the client running on some servers called "1.", "2.", "3." etc.

Since the latest Java upgrade (now running on 1.8.0_65-b17) we got the following error:
java.rmi.ConnectIOException: Exception creating connection to: 0.0.0.4; nested exception is:
java.net.SocketException: Invalid argument or cannot assign requested address

That looks connected to the Java issue: https://bugs.openjdk.java.net/browse/JDK-8191991
(there is a similar issue on the Oracle JDK too).
The Riemann client seems also unable to pickup a different server name from the yaml file.

add default host

Is it a little better to have local hostname as the default "host" param for jmx in *.yaml file ?
Such as when the user doesn't give riemann-jmx a specific host param, riemann-jmx get local hostname as "host" param automatically.
If you agree with this please let me know and I can give a PR.

is it possible to disable netty epoll and rebuild with lein

our centos image has restrictive policies for /tmp, and I cannot seem to force the java process to use an alternate tmp dir. It could also be umask related, but first I would like to to build riemann-jmx-clj without netty epoll. the error i'm getting while trying to start the service is

i have forked the riemann repo and commented out the epoll lines in https://github.com/rojomisin/riemann/blob/epolldisabled/src/riemann/transport/tcp.clj

Can I now build this by pointing the project.clj url at this branch?
https://github.com/twosigma/riemann-jmx/blob/master/project.clj#L3

thanks for any help!
