Identify your Landscape version

Note

Landscape beta versions run ahead of the Landscape SaaS version, and the Landscape SaaS version runs ahead of of self-hosted Landscape versions.

You may need to know what version of Landscape you’re running. To identify your Landscape Server and Landscape Client versions:

  • Landscape Server: Add /about to the URL of your Landscape account. For example, https://landscape-server.domain.com/about. If you’re using Landscape SaaS, the URL is https://landscape.canonical.com/about. If you’re using self-hosted Landscape, you can also run apt policy landscape-server in the command line on the server machine.

  • Landscape Client: Run apt policy landscape-client in the command line on the client machine.

  2. Click the desired tag from the left column. This will select only the computers associated with the selected tag.

  3. Click Packages

Activities - Upgrade pending approval

Note: While the upgrade tasks are now in the queue, they will not be executed until you approve them. To approve the tasks, click All, then click Approve.

Keep a set of machines automatically up to date

  3. Specify a title for your new access group

  4. Click Save.

You must then add computers to the access group:

  1. Click Computers in the header

  2. Select all of the machines you want to keep updated by:

    • using a tag if one exists

    • using search to find the machines

    • selecting them individually

  3. Click Info

  4. In the Access group section, select the access group you want to move the machines to

  5. Click Update access group.

Once you’ve added machines to an access group, you’ll need to create an upgrade profile:

  1. Click on your organization’s name in the header

  2. Click Profiles

  3. Click Upgrade Profiles

  4. Click Add upgrade profile

  5. Complete the Create an upgrade profile form, defining:

Keep Landscape from upgrading a certain package on one of my servers

  4. Click the triangle on the left of the listing line of the package you want to hold, which expands the information for that package.

Create a custom graph

Suppose you want to monitor the size of the PostgreSQL database on your database servers, you may use tags to group these machines together. Now you can create a graph to provide information from all of these servers:

  1. Click on your organization’s name in the header

  2. Click Graphs

  3. Click Add graph

  4. Complete the Create graph form. In our example, we could do something like:

    • Title: PostgreSQL database size

    • Provide a “Y-axis title” and define the machines you want the graph created for.

    • Run as user: postgres

    • Code:

      #!/bin/bash
psql -tAc "select pg_database_size('postgres')"

  5. Click Save

Create custom graph

To view the graph, click Computers in the header, then click Monitoring. You can select the monitoring period from the dropdown menu at the top of the window.

Ensure all computers with a given tag have a common list of packages installed

Manage them via a Package profile.
