Snapshot of dlmon, or the current state-of-health of the TA network. Sortable by column heading, arrow direction signifying forward or reverse sort. Click a value to observe the graphical trends for this parameter over mulitple time periods. The arrows below the table allow you to view 'pages' of the table. Modify the value in the drop-down menu to alter the number of table rows shown per page. Default is 25 rows.

The table is initially sorted on data latency (dltncy column). Data is regenerated every 5m. Refresh the page to see the latest data.
