Want to make your Grafana dashboards truly shine? It is not enough to just throw some metrics on the screen and call it a day. The right visualization can make all the difference in how quickly you spot trends, detect problems, and understand your data. Grafana has lots of ways to show your data, and some of them are amazing.
In this article, I am going to walk you through nine of the best Grafana visualization panels. Each one has its own special skill for different kinds of data. By the end of this article, you will have ideas on how to make better dashboards that are more useful and easier to read. Get ready to make your data come to life.
Time Series: The Heartbeat of Your Data
The Time Series panel is the go-to for showing how data changes over time. Think of it as the heartbeat of your metrics. It can show you the ups and downs of your system’s performance, traffic, or anything else that fluctuates.
When to Use
You should use the Time Series panel when you want to track how a value changes over a time period. This is very useful for watching trends or finding problems that happen over time. For instance, think of CPU use, memory use, or the number of requests coming to your server.
How to Make the Most of It
- Choose the right time range: Pick a time that shows what you need to see, be it the last hour, day, week, or more.
- Use clear labels: Make sure axes and data points are well-labeled. This helps anyone reading your dashboard quickly grasp what is going on.
- Use different line styles and colors: This makes it simple to spot each value. For example, use a solid line for one metric and a dashed line for another.
- Add annotations: Use annotations to show when events happened. Like when you deployed new code or when a server went offline.
- Overlay data: You can show many metrics on one graph. This helps you see how they relate to one another.
Stat: A Quick Look at Key Numbers
The Stat panel is all about showing one or two key numbers. It gives you quick insights without having to look at charts or read lots of data. It is great for tracking how well your system is working or hitting certain goals.
When to Use
Use the Stat panel when you want to show one or two numbers that matter the most. For instance, you may want to see the total number of errors for today, the number of active users, or how long a process usually takes. This panel is best when you need to know a quick status update.
How to Make the Most of It
- Use threshold colors: Set up colors for when values go above or below certain levels. Red for critical issues, for example.
- Show sparklines: You can show a tiny graph under the main number. This gives you a quick look at how the value has changed over time.
- Add prefixes and suffixes: Adding the right units (like %, MB, or ms) makes the values easier to read.
- Change font size: Use a bigger font for the main value and a smaller one for the sparkline or labels. This helps you focus on the most important number.
- Use different value formats: You can show numbers as decimal, percent, or with added units.
Gauge: Track Progress Toward Goals
The Gauge panel helps you track your progress. It is a visual way to see how close you are to hitting a goal or how full your cup is. It uses a dial or bar to show how far along you are, which makes it easy to understand.
When to Use
Use the Gauge panel when you want to show how close you are to meeting your aim. This is great for watching progress on a KPI (key performance indicator). For example, how much storage is left, or how much of a job is done.
How to Make the Most of It
- Set clear min and max values: Define the min and max for your gauge. This makes sure the range of your gauge is right for your data.
- Use thresholds for different zones: Set up colors for parts of the gauge. For example, green when everything is good, yellow when you are getting close to the limit, and red when you have hit it.
- Use a dial or bar gauge: Pick the type of gauge that best fits your data and look.
- Add value labels: Place the current and min/max numbers on the gauge to give more context.
- Add a subtitle: Use a subtitle to explain what the gauge is measuring.
Bar Chart: Compare Data Points
The Bar Chart panel is good for comparing different values side by side. It uses bars of different heights or lengths to show each value. This makes it easy to spot the biggest and smallest values in your data set.
When to Use
You should use the Bar Chart panel when you have to compare different categories or values. This is useful for comparing the amount of traffic to different pages, or the performance of different servers.
How to Make the Most of It
- Use clear category labels: Make sure each bar has a clear label.
- Use color to show different groups: If you have many groups, use different colors to tell them apart.
- Sort bars: Sort bars by size to make the chart easy to read.
- Use stacked or grouped bars: Use grouped bars to compare related values. Use stacked bars to show the total of parts that make a whole.
- Add data labels: Show numbers at the top of each bar to make it more precise.
Pie Chart: Show Parts of a Whole
The Pie Chart panel is great for showing how the parts make up the whole. It uses slices of a circle to show each part. The size of the slice shows how big that part is. This is easy to understand because most people know about pie charts.
When to Use
Use the Pie Chart panel when you want to show how a total amount is split into parts. For example, if you want to show the breakdown of traffic by device type (desktop, mobile, tablet). Or, if you want to show how much of your cloud expenses go into specific services.
How to Make the Most of It
- Use clear labels for slices: Make sure each slice has a clear name, so users know what part it is.
- Use different colors: Pick colors that are easy to see and tell apart.
- Keep slices to a reasonable number: A pie chart with too many slices is hard to read. Try not to go over five to seven slices.
- Add percentages: Show percentages in or next to each slice. This gives users a better idea of how big each part is.
- Add a legend: A legend can help users know which slice is which.
Table: See Raw Data
The Table panel is where you show the actual data in a structured way. It displays your data in rows and columns. It is useful when you want to see the exact numbers, or when you have more complicated data that other panels can’t show.
When to Use
Use the Table panel when you need to see the exact data or when other panels do not fit. This is great for showing log data, lists of servers, or other details that you would not want to turn into a chart.
How to Make the Most of It
- Use clear headers: Make sure each column has a clear label that tells what data it holds.
- Format data: Use clear formats for numbers, dates, and text. This makes the table easier to read.
- Use filters: Set up filters to see only the data you need.
- Add sorting: Allow users to sort the table by different columns.
- Use thresholds for different colors: Use color to highlight values that are very important, or that do not meet criteria.
Heatmap: Spot Patterns in Dense Data
The Heatmap panel uses color to show where data points are more or less dense. This lets you quickly see patterns and outliers in big data sets. This method is helpful when you have data spread over two axes.
When to Use
Use the Heatmap panel when you have to find patterns in dense data or look for outliers. For example, this could be how often different errors happen at different times. Or, it could be when certain users use your platform.
How to Make the Most of It
- Choose the right color scale: Pick a color scale that fits your data well.
- Adjust the size of the cells: The size of each square matters. Adjust it to show your data well.
- Add axis labels: Make sure both axes have clear names. This lets users know what they are looking at.
- Use tooltips: Show detailed information when the user hovers over a square.
- Adjust the aggregation method: Pick the way the data is summed or counted. The default might not be the right pick for you.
Worldmap: Track Geographic Data
The Worldmap panel lets you show data on a world map. You can place data points or regions on the map and color them based on the values. This is good for data that has to do with geography.
When to Use
Use the Worldmap panel when you have data that is linked to a location. This panel can show where your users are coming from. Or, where your servers are located, and how they are doing.
How to Make the Most of It
- Use clear color codes: Pick colors that clearly show the different values.
- Use location names: Name each point or region clearly on the map.
- Set up zoom: You can let users zoom in on different parts of the map.
- Use different marker sizes: If you have points, use sizes to show how big the value is.
- Use tooltips: When the user hovers over the point or region, show more data.
Text: Show Information and Guides
The Text panel is good for adding notes, instructions, and other details to your dashboard. You can use it to show information that is not from the metrics themselves. It is where you can write about the dashboard or give extra context.
When to Use
Use the Text panel when you want to add notes or guides to your dashboard. For example, it can describe what metrics mean, tell people what to do, or give an explanation of the dashboard.
How to Make the Most of It
- Use headers and lists: Break up the text to make it easier to read.
- Use bold or italic text: Use different text styles to mark important parts of the text.
- Add links: Link to related documents or other dashboards.
- Use HTML: You can add basic HTML to your text to give it more style.
- Update often: Check your text panels often to make sure they are still right and useful.
Choosing the Right Panels for Your Data
