Understanding Dashboards

The Metrics Monitor tool provides a historical view of metrics that are critical to a database server. Time-based graphs are separated into dashboards by themes: some are related to MySQL or MongoDB, others provide general system metrics.

Opening a Dashboard

The default PMM installation provides more than thirty dashboards. To make it easier to reach a specific dashboard, the system offers two tools. The Dashboard Dropdown is a button in the header of any PMM page. It lists all dashboards, organized into folders. Right sub-panel allows to rearrange things, creating new folders and dragging dashboards into them. Also a text box on the top allows to search the required dashboard by typing.

With Dashboard Dropdown, search the alphabetical list for any dashboard.

Viewing More Information about a Graph

Each graph has a descriptions to display more information about the monitored data without cluttering the interface.

These are on-demand descriptions in the tooltip format that you can find by hovering the mouse pointer over the More Information icon at the top left corner of a graph. When you move the mouse pointer away from the More Information button the description disappears.

Graph descriptions provide more information about a graph without claiming any space in the interface.

Rendering Dashboard Images

PMM Server can’t currently directly render dashboard images exported by Grafana without these additional set-up steps.

Part 1: Install dependencies

  1. Connect to your PMM Server Docker container.

    docker exec -it pmm-server bash
    
  2. Install Grafana plugins.

    grafana-cli plugins install grafana-image-renderer
    
  3. Restart Grafana.

    supervisorctl restart grafana
    
  4. Install additional libraries.

    yum install -y libXcomposite libXdamage libXtst cups libXScrnSaver pango atk adwaita-cursor-theme adwaita-icon-theme at at-spi2-atk at-spi2-core cairo-gobject colord-libs dconf desktop-file-utils ed emacs-filesystem gdk-pixbuf2 glib-networking gnutls gsettings-desktop-schemas gtk-update-icon-cache gtk3 hicolor-icon-theme jasper-libs json-glib libappindicator-gtk3 libdbusmenu libdbusmenu-gtk3 libepoxy liberation-fonts liberation-narrow-fonts liberation-sans-fonts liberation-serif-fonts libgusb libindicator-gtk3 libmodman libproxy libsoup libwayland-cursor libwayland-egl libxkbcommon m4 mailx nettle patch psmisc redhat-lsb-core redhat-lsb-submod-security rest spax time trousers xdg-utils xkeyboard-config alsa-lib
    

Part 2 - Share your dashboard image

  1. Navigate to the dashboard you want to share.

  2. Open the panel menu (between the PMM main menu and the navigation breadcrumbs).

  3. Select Share to reveal the Share Panel.

  4. Click Direct link rendered image.

  5. A new browser tab opens. Wait for the image to be rendered then use your browser’s image save function to download the image.

If the Grafana plugins are not installed, a message in the Share Panel will say so.
