History

Go back in time to see historical parameter values

CloudTruth offers the ability to see a project's historical parameter or template values on demand. These values can visualized by entering a date-time stamp or environment tag (effectively a date-time stamp).

Parameter History

• Open the parameter value history view by expanding Reports, via the left-hand navigation menu, and clicking the History option.

• Based on the currently selected project and environment shown in the global project selector, the project's parameter list table will be displayed. Here we have selected MyFirstProject and the production environment:

Once the page has been accessed we can now view the history by either selecting a date and time or choosing an existing environment tag.

Viewing by date and time

• Clicking in the Select date field will open a date-time picker or the date and time can be entered manually following the YYYY-MM-DD hh:mm:ss format

• Clicking OK then Apply will submit the data and retrieve the historical values. The image below shows param_2 was modified (overridden) after the selected date:

Viewing by Tag

Environment Tags represent a date and time stamp with the added convenience of being identified by name. We've already created an environment tag representing the same date and time we selected when viewing by date and time in the previous section.

• Select the existing environment tag then click Apply to submit the tag and retrieve the historical values. As above, the image below shows param_2 was modified (overridden) after the set date within the environment tag:

Template History

In the example above we demonstrated how to view the historical differences between a project's parameter values. We can also view the historical differences between a project's templates. Choosing the environment tag or selecting a date and time stamp is the same, but the view needs to change. In this example we will check the project's default environment and an environment tag to see the template differences.

• Select the Templates option to change to the template view:

• Select the existing environment tag then click Apply to submit the tag and retrieve the historical values and list any existing templates:

• Click the Show differences expander to view the differences between the current and tagged template versions (in this case we only have a single template available):
