Viewing Diagnostic Messages for a Component
Viewing Messages from Multiple Components
The EIQ Diagnostics Tool is used to view diagnostic messages from EIQ Product Suite components. This diagnostic trace aids users and developers in tracking down and diagnosing any issues with EIQ Product Suite components.
Each EIQ Product Suite component (executables and libraries) writes diagnostic messages to Windows message sinks. The EIQ Diagnostics Tool taps into these message sinks and displays messages as they arrive. Users must open a diagnostic window for each component they are interested in monitoring.
Users don't have to setup the diagnostic message sinks. Components create message sinks when they are loaded for the first time. These message sinks are local to the machine, so the Diagnostics tool must run on the same machine where the components are running.
Note: A single library component may be loaded at the same time by different components. For example, the WhamNAPI component may be loaded by both the EIQ Server and the EIQ Query Tool components. Each loaded instance of the component creates its own sink identified with a unique name composed of its own name and the name of the loading component. In the above example, 'User1_WhamNAPI_EIQServer' and 'User1_WhamNAPI_EIQQueryTool' could be two sink names for the two loaded instances of WhamNAPI library.
· Start the 'EIQ Diagnostics Tool'.
· Sign in with your username and password.
· Select the application name from the drop-down list of registered EIQ Product Suite components.
· Click 'OK'.
· The EIQ Diagnostics Tool opens a message window where the diagnostics messages are displayed for the selected component.
· User can see any diagnostic messages as they are posted by the component in the window.
To watch messages for more than one component at the same time, click 'File->New' and select the component name. It opens a new message window for diagnostic messages from the selected component.
Users can save messages to a log file.
When users select a component, by default the 'Write diagnostics to log file' option is selected. This writes diagnostic messages to a log file named after the component under the 'WhamTech\log' folder in the install path.
Users can also save messages to a log file by clicking 'File->Save'.
The diagnostic level can be changed in both the component selection window and in the main program window. There are five levels.
Level 1 – FATAL: A very serious error has occurred that can lead to the application aborting.
Level 2 – ERROR: An error has occurred but the application may still continue to run.
Level 3 – WARNING: There is a potentially harmful situation occurring.
Level 4 – INFO: Provides informational messages highlighting the procedures of the application.
Level 5 – DEBUG: Provides details on informational events that are useful in debugging the application.
Levels 1-5 can be selected from the main program window after loading the component being diagnosed. Levels 4-5 can be selected from the second drop-down bar in the main window or from the component selection window.
To clear messages from the currently highlighted window, use
the 
icon on the toolbar. To clear the messages
from all the windows that are open in the current session, click the 
icon on the toolbar.
To filter-out unwanted messages, select 'View->Filter Messages' and enter a keyword that must be present in a diagnostic message. All messages without the keyword will not appear in the message window.
By selecting 'Windows->Cascade' or 'Windows->Tile', users can re-arrange multiple message windows.
Users can pause or resume receiving messages in a message window by clicking the icons for pause and resume. Selecting 'pause' for an active window halts diagnostic message retrieval for that window. ‘Resume’ starts receiving diagnostic messages from that point in time. Even after a resume, a message window does not display any messages output by its application during the 'pause' period.
