Grafana Status Panel: A Comprehensive Introduction

Grafana Status Panel is a versatile plugin designed to provide a comprehensive snapshot of the status of various components at a glance. This tool is particularly useful for organizations that need to monitor multiple metrics across numerous servers or components simultaneously. Unlike the Single Stat panel in Grafana, the Status Panel can handle multiple values from the same data source, offering a more detailed and customizable monitoring experience.

Overview and Purpose

Suppose you need to keep an eye on multiple statistics for several servers. The Grafana Status Panel allows you to monitor these stats efficiently by providing a centralized view. It supports various customization options to mark different states of the components:

• Severity Marker: Allows you to set thresholds to indicate the severity level (OK, Warning, Critical) of a component. The panel highlights the state with colors—green for OK, yellow for Warning, and red for Critical.

• Disable Marker: Designates a specific value as an indicator that a component is disabled, turning the panel gray.

• Text Display: Provides additional information about the component on the panel.

Installation Guide

To install the Grafana Status Panel for debugging purposes, follow these steps:

1. Copy the "Grafana_Status_panel" contents to the "/var/lib/grafana/plugins" directory on your server.
2. Restart Grafana by executing the command service grafana-server restart.
3. The panel should now be available for use in Grafana.

How to Utilize the Panel

1. Add Queries: Include the desired queries in the panel, assigning each a unique alias.

2. Panel Title: Choose an appropriate name for the panel in the Panel Title field. This field is template-compatible, meaning when the panel is repeated, the correct name will display.

3. Configure Options: Navigate to the Options tab to manage each metric's treatment:

   • For severity display, select a Threshold type (Number, String, or Date). Set Warning and Critical thresholds, and adjust display settings as needed.

   • For disable display, utilize the Disable Criteria option, specifying the Disable Value for each query.

   • For simple text display, choose the Text Only option type. The panel will show the metric's alias and value.

4. Data Aggregation: If queries return multiple values, select an aggregation type. Choosing None will use the first item from the result.

Additional Features

• Remove Prefix: Simplifies panel names when repeated by removing specified prefixes, allowing for clearer display information.

• Display Value by Regex: Facilitates the display of specific value portions by matching regex patterns, showing only the first match or the original value.

• Measurement URL: Provides actionable links for users to access additional information or instructions, especially useful for Warning or Critical states.

• Threshold Preferences: Customize display settings (such as colors and text formatting) based on metric states (ok, warning, critical, disabled).

• Show Disable for No Data: Enables the panel to appear disabled (gray) in the absence of data if Make panel gray when no data is checked.

Supported Data Sources

Currently, the Grafana Status Panel supports InfluxDB and Graphite. Expansion to other data sources is possible upon request.
