dynatrace-appmon-docker-monitor-plugin's Issues

Plugin crashes with 32 bit JVM

since you just bundle the 64 bit .so it fails to start on 32 bit

Exception "Recevied null value from the docker query for container and image count in UnixSocketDataCollector"

When I try to run the plugin on a machine where a Dynatrace Collector is running with configuration SSH-Local, I get the following error, although the socket is available.

~$ ls -al /var/run/docker.sock
srw-rw---- 1 root docker 0 Jul  7 21:50 /var/run/docker.sock

Making the socket-file read/writeable for all did not make it work. When I try to connect via ssh I get "2015-07-22 06:39:34 SEVERE [DockerMonitor@Docker Monitor_0] There was a problem while connecting to localhost:22"

Error details are:
