The HPS Monitoring Application is a Java Swing GUI application which provides an online data monitoring framework for the experiment.
Installation
The application is part of the HPS Java project, so the Installing HPS Java instructions should be followed to build it.
You may also find an hps-distribution jar using a Nexus repository search and download it through the web interface.
Running
The application is activated through its main method and takes only one command line argument, which is the name of a settings properties file.
java -jar hps-distribution-bin.jar org.hps.monitoring.application.Main -c settings.prop
The settings files are not typically hand edited but created by saving settings from the GUI's menu.

Starting and Stopping a Session
Saving and Loading Settings
Settings can be saved under Save Settings in the Settings menu.
Previously saved settings may also be loaded in the application under Load Settings in the Settings menu. You should give these files the extension of .prop to indicate that they are Java properties files. The settings will not take effect until a new session is started. If there is a currently active session, it will not be affected.
Configuring Settings
Settings can be configured in the GUI by clicking on Open Settings Window under the Settings menu.
The first tab contains settings for configuring the application's connection to an ET server.
| Setting | Description | Notes |
|---|---|---|
| ET Name | name of the ET buffer file | |
| Host | ET server's TCP/IP hostname | |
| Port | port for connection to server | |
| Blocking | block when reading from ET system | usually should be deselected |
| Verbose | run ET station in verbose mode | |
| Station Name | the name of the ET station used by the monitoring application | should not exist already |
