Monitoring¶

The goal of monitoring is to be aware of the state of your Virtual DataPort servers in real-time and detect malfunctions as soon as possible so you can take action to solve them.

The Diagnostic & Monitoring Tool displays the status of the Virtual DataPort servers using graphs and tables that are updated every few seconds.

You can visualize with graphs the resources information of a monitored server, for instance, like in the figure below.

Monitoring information presented with graphs¶

Discovering the actual values in the graphs is as easy as moving the mouse over a graph. Graphs are synchronized, so you can track all their series data at once. You only need to move the mouse over one of the graphs, and a tooltip will appear in all the visible graphs showing the values for their measures at that instant. You can click on a graph and the tracking will freeze, ignoring the mouse movement, so you can inspect the frozen instant for all the graphs. Click again, and the tracking will resume. In addition, if the series points are visible, graphs will highlight which points are considered for the tracking.

For each graph, its header contains its name and a set of icons to operate with it:

• : Pauses obtaining new monitoring data.

• : Resumes obtaining new data, so the graph updates the information at a certain interval. You can change how often the data is refreshed.

• : Removes the current data from the graph.

• : Unfolds a menu with the following option to configure the graph:

  • Max visualization time interval: Maximum number of minutes can pass between the first and the last measures until the graph starts discarding data. The graph will discard those measures that are older than this value.

• : Displays a menu where you can choose which series the graph will display.

The figure below shows an example of monitoring information displayed as a table. As with the graph, the header shows the name of the table and a set of icons to operate with it. You can click on the header and the table will collapse.

Monitoring information presented in a table¶

The icons in the header of a table are:

• : Stops refreshing the table.

• : Starts refreshing the table. The countdown in the header of the table shows the time until the next refresh.

• : Forces a refresh of the table.

• : Unfolds a menu with the following options:

  • Refresh interval: Number of seconds between automatic refreshes of the content of the table.

  • Max rows: For the tables that hold historical data, maximum number of rows of the table.

• : Displays a menu where you can choose which fields the table will display.

• : Displays a dialog to define a condition to filter the contents of the table. Depending on the type of the field selected, the type of condition is different:

  • MIN-MAX: Applied to numbers or dates, it sets the minimum and/or maximum value the field can take.

    

    Dialog of a MIN-MAX filter¶

  • IN: Applied to enumerated values, this filter defines a set of values with which to compare the field. You have to click on the icon to add a value to the set or click on its icon to remove it. The field must be equal to one of the values in the set to pass the filter.

    

    Dialog of an IN filter¶

  • TRUE-FALSE: Applied to boolean values, this filter checks if the field is true or false, according to the value that is selected.

    

    Dialog of a TRUE-FALSE filter¶

  • LIKE: Applied to texts, this filter sets the value with which to compare the field. If Exact is selected, the whole text must be equal to this value to pass the filter. When cleared, the value is interpreted as a regular expression and only a substring of the text must match it to satisfy the filter.

    

    Dialog of a LIKE filter¶

Double-click on a row, or right-click and select View Row, to see all its fields. This is useful if you configured the table to display only some fields.

The information dialog shows the values for all the fields of a row¶

Some tabs have the icon, which unfolds a menu with the following options:

• : Collapses all the graphs and tables in the tab.

• : Expands all the graphs and tables in the tab.

• : Starts the monitoring of the graphs and tables in the tab.

• : Stops the monitoring of the graphs and tables in the tab.
