Logscape makes use of Hawt IO in order to allow the user internal visibility of what is currently happening in their environment. Hawt IO is capable of showing JMX attributes in an attrictive GUI as well as showing information on Threads, and overall system health.
Hawt IO can be acessed via the 'Systems' tab of the Logscape settings menu, simply click the 'System Admin Console' button.
Clicking through to the Admin console, you're welcomed by the Hawt IO connection screen.
Name : Manager Scheme : HTTP Host: (Default is localhost) Port: (Logscape default is 11006) Path: jolokia Username: Admin username Password: Admin password
Onced logged in you will be greeted by the Hawk IO Dashboard, from here you can choose to navigation to the JMX or threads tabs, or simply monitor metrics about the Java processes within your environment.
Hawt IO Allows a system adminstrator easy access to information relating to the Java Virtual Machine through their entire environment, allowing another form of metrics. It is especially useful for monitoring, and debugging Logscape performance, as it will become clear when the JVM is becoming overloaded due to Logscape processes.
If you believe that scaling is negatively impacting your Logscape installations performance, then please read the Sizing Guide.
By default your configuration will allow you to monitor localhost, meaning you are able to see the java process for the manager, however it is possible to monitor remote machines through proper configuration. On your remote host navigate to and open your boot.properties. The following shows a default Hawt configuration.
jolokia.agent=-javaagent:downloads/jolokia-agent.jar=port=11006,host=localhost
If you wish you can modify the port.
From here, return to your manager and with it, the system admin console.
At this screen rather than choosing 'localhost' as your Host value, simply enter the IP or Hostname of your remote host and connect as per normal.
Hawt IO is configured in the Logscape boot.properties file, all settings relating to Hawk IO can be found in the following line
jolokia.agent=-javaagent:downloads/jolokia-agent.jar=port=11006,host=localhost
