Having issues with HA Proxy Monitor

[CommunityUser]

I have been using the appdynamics java and standalone agent with no issues in our environment, but now that we are attempting to monitor our HA Proxy servers I am running into issues. I installed the HA Proxy Monitor from under monitor folder of the standalone agent:

http://community.appdynamics.com/t5/eXchange-Community-AppDynamics/HA-Proxy-Monitoring-Extension/idc...

However it fails to load the HA Proxy Monitor due to a missing library file:

[Agent-Monitor-Scheduler-2] 28 Apr 2015 16:54:47,868  INFO PeriodicTaskRunner - Periodic Task - setup metric feed for [HAProxy Monitor Run Task]

[Agent-Monitor-Scheduler-2] 28 Apr 2015 16:54:47,869  INFO HAProxyMonitor - Starting the HAProxy Monitoring Task

[Agent-Monitor-Scheduler-2] 28 Apr 2015 16:54:48,220 ERROR PeriodicTaskRunner - Error creating environment task

java.lang.NoClassDefFoundError: org/apache/commons/httpclient/HttpConnectionManager

        at com.appdynamics.extensions.haproxy.HAProxyMonitor.execute(HAProxyMonitor.java:104)

I checked the jar that is associated with the monitor and don't actually see http client under there. I am specifying the default value for the host as localhost with port 80. Any ideas why I am having this missing library issue? Thanks!

Thanks for the reply. I was able to get it working after I contacted AppDynamics support and they provided me with a new AppDynamics jar that included the missing files.
