Retrieving monitoring information

To access monitoring functions, select Monitoring from the main menu bar, and select
the category and function of interest. Results are displayed in tabular format, with the
ability to page to more results. In some cases the information is color coded to
facilitate easier analysis. The reload button re-issues the monitoring query, facilitating ad-hoc snapshots of monitoring data.
