The System Monitor display allows for viewing the status of the system. The behaviour of the System Monitor is different depending on the use of the system, i.e. whether you are using the system in Stand Alone mode or as an Operator Client.
In the Stand Alone Standalone mode the System Monitor will display the Log Browser and Batch Forecast tab. On overview of the tabs available in the System Monitor of a Standalone system is illustrated below.
In an Operator Client the System Monitor will show a number of tabs for monitoring various aspects of the live system. On overview of the tabs available in an Operator Client when logged into a live system is illustrated below.
Each of the System Monitor tab tabs is detailed in the following paragraphs.

The Log Browser contains a spreadsheet like form with a list of system messages. Messages can be sorted based on user defined criteria. Fatal and severe system errors can be acknowledged as being reviewed by the forecaster. If all errors within the past 48 hours are acknowledged the system status icon at the lower right of the FEWS explorer will become green again.

With \[Refresh\] the browser is updated with new messages in the system. Please note that the query settings (see below) define what messages will be displayed. With \[Close\], a user can leave the Log Browser. |
Upon opening, the same information is displayed as in the Log Viewer. Per message, the Log Browser provides the following information:
...
Log level | Icon | Description |
Fatal | | Severe errors that cause premature termination |
Error | | Other runtime errors or unexpected conditions |
Warn | Events that are undesirable or unexpected, but not necessarily wrong | |
Info | Runtime events (startup/shutdown) that allow tracking of the progress of the system |

Double click a message to view the message details (see example below). The message can then be saved to file or printed.

When all ERROR messages are acknowledged, the status icon in explorer will change to green.
Debug messages
Please note that a System Manager can configure the system to also provide Debug Messages . These are used to log application internal events for system development and management. Typical debug events are the creation of a database connection or exceptions that occurred due to programming or configuration errors. Debug messages are not displayed in the Log Viewer but only written to a log file called log.txt in the regional configuration folder.

The Scheduled Forecasts tab includes a list with all scheduled forecasts together with some critical information of these forecasts. The following information is included:
- Task ID: The Task ID is a unique ID generated by the Master Controller
- Description The description is given by the user that scheduled the forecast
- Workflow ID The Workflow ID is the id of the workflow that is scheduled. The workflow id's can include Forecasting Shell workflows and Master controller workflows.
- MC ID ID of the Master Controller where the task is scheduled on
- Priority This can be a high or normal priority
- Repeat Time The repeat time of the task in minutes
- Next Due Time The next time when the task is scheduled to run
- Task Status The status can be suspended or pending. Suspended tasks normally depend on an action to trigger them, such an action can be a threshold crossing.
The Scheduled Forecast tab allows to cancel, pause or suspend tasks. By that it's possible to change the start time of ascheduled forecast.
In the Scheduled Forecast tab a user can...

You can undo the pausing by resetting the number of runs for which a task has been paused to '0'.

The Running Forecasts Tab includes a list with all tasks that are currently running on a Forecasting Shell. The list includes information on the task that is running and the Forecasting Shell it is running on.
From the example below can be seen that the first task is a Rolling Barrel task, running on the Master Controller. The second task is a Riverflow Forecast running on forecasting Shell FSS00.
