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.

Monitoring information presented in a graph shows an example of a graph with two series. The header of the graph contains its name and a set of icons to operate with it.

The icons in the header of a graph are:

  • image1: Pauses obtaining new monitoring data.
  • image2: Resumes obtaining new data, so the graph updates the information at a certain interval. You can change how often the data is refreshed.
  • image3: Removes the current data from the graph.
  • image4: Displays a menu with options to configure the graph:
    • Enable tracking: if selected, you can pass the cursor anywhere in the graph to obtain the current measure for all the series at this exact moment. If cleared, you only obtain the measure of one series when you place the cursor over it.
    • Show points: If selected, the graph displays a point at every moment the polling took new data.
    • 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.
  • image5: Unfolds 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:

  • image1: Stops refreshing the table.

  • image2: Starts refreshing the table. The countdown in the header of the table shows the time until the next refresh.

  • image3: Forces a refresh of the table.

  • image4: Displays 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.
  • image5: Unfolds a menu where you can choose which fields the table will display.

  • image12: 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.

    • IN: Applied to enumerated values, this filter defines a set of values with which to compare the field. You have to click on the image14 icon to add a value to the set or click on its image15 icon to remove it. The field must be equal to one of the values in the set to pass the filter.

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

    • 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.

Double-click on a row, or right click and select image19 View Row, to see all its fields. This is useful if you configured the table to display only some fields.

Some tabs have the image21 icon, which unfolds a menu with the following options:

  • image22: Collapses all the graphs and tables in the tab.
  • image23: Expands all the graphs and tables in the tab.
  • image2: Starts the monitoring of the graphs and tables in the tab.
  • image1: Stops the monitoring of the graphs and tables in the tab.
