JCR content

The Environments subsection displays information related to JCR content for your DX Cloud project. From here, you can see metrics on the size of frontend environments within JCR workspaces as well as query or count node types on a workspace.

In this section, you need to select your desired Release and Pod as the metrics and results are related to the choices there.

jcr content tab

JCR workspaces

In this JCR workspaces tab, you can see the number of nodes from the nt:base type per JCR workspace. The table displays the name of the workspace and the size of the associated frontend environment.

JCR query

In the JCR query tab, you can see the most common node types in the applicable workspace including those shown below. You can also use the Query generator to count or query a certain node type per selected workspace.

Query generator

To use the JCR Query generator:

  1. Go to Environments > JCR content > JCR query (tab).

  2. Scroll to the Query generator.

    1. Select a Workspace.

    2. Select a Node type.

    3. Select Count or Query.

      Count counts the number of node types per workspace.

      Query queries the node types in a workspace to show you the paths.

Persistence database

The Persistence database gives you an area to quickly see the size of the database. This is displayed under Database size at the top of the page. You can also see the size per table which is shown in the table on the tab.

Here, you can see:

  • The namespace

  • The database name.

  • The number of rows in the database.

  • The size of the database.

  • The relation size.

  • The index size.

  • The total size of the database.

Vacuum database

If you want to vacuum your database and keep things running a little tighter, you can do that by simply clicking the accordion symbol to the right of your chosen database and clicking the Vacuum button. You’ll be prompted to be sure that’s what you want to do before officially hoovering up that unwanted space.

For more on the VACUUM command, see here.

Publications

The Publications tab under Environments lets you view publishing operations from the Cockpit. Publishing operations consist of publishing content from Author to Public.

  1. From your Cockpit, go to Environments > Publications (tab).

  2. Choose your desired Release from the dropdown menus.

  3. Choose your desired actions from the available tabs.

    • Overview

    • Repartition

    • Logs

    • Error logs

    View the publication operations in this tab.

    1. publishing requests when content is published from Author to Public.

    2. unpublishing requests when content is unpublished.

    3. errors when a publishing error occurs.

    4. committed transactions when content is committed.

    5. rolled back transactions when content is rolled back from Public back to Author.

    6. published content size shows in bytes the total value for publish content

    7. published content time shows in milliseconds how much time it took to publish content

You can add, adjust levels, and delete Loggers from the Cockpit.

  1. First, in your Cockpit go to Environments > Loggers.

  2. Select your Release and Pod to display your Loggers.

Manage your environments

Manage your environments via the Cockpit by going to Environments and selecting Manage. You can manage both your integration and production (prod) environments here. Within the environment, you are able to manage your DX Cloud backend and frontend separately.

The examples and descriptions below apply to both backend and frontend environments as well as both author/public instances.
manage environments
No Item Description

1

Start

Start your environment.

2

Stop

Destroys all instances down to 0 replicas.

3

Delete indexes

Delete the environment’s indexes. See Delete Indexes for instructions.

Deleting an index shuts down Magnolia. The subsequent restart will be slower, because Magnolia is rebuilding the index.

4

All containers

Display a list of all containers associated with the environment. Information such as the following is available:

  • State: The current state of the container (e.g., running, terminated)

  • Ready: Whether the container is ready or not. A signals the container is ready.

  • Name: The name of the container.

  • Started: The date and time when the container was started.

  • Finished: The date and time when the container finished.

  • Reason: The reason why the container stopped.

  • Message: A message about the container (if any messages were added).

environment all containers

See logs

Takes you directly to any applicable log information. See Logs for more details.

Delete an environment

You can delete an environment directly from the Cockpit.

This action permanently deletes the selected environment and cannot be undone.

Instructions

  1. Go to Environments > Manage.

  2. Go to the environment that you want to delete.

  3. Click Delete environment.

  4. Follow any on-screen instructions for confirming the deletion.

Delete Indexes

You may want to completely delete the indexes for an environment. This can be done directly through the Cockpit.

What happens when I delete an index? 🤔

After deleting an index, the system restarts and rebuilds them based on the data found in the persistence database.

Downtime varies depending on the amount of data associated with an index. This duration ranges from seconds to hours depending. To help reduce this downtime, we use the rollingUpdate approach.

To delete the index folders:

  1. Go to Environments > Manage.

  2. Click Delete indexes for the desired environment.

1. The levels available are standard Log4J log levels: ALL; TRACE; DEBUG; INFO; WARN; ERROR; FATAL; OFF.
