Grafana gauge tutorialWhen working with Grafana and Graphite, it is quite common that I need to calculate the percentage of a total from Graphite time series. There are a few variations on this that are solved in different ways. With the SingleStat panel in Grafana, you need to reduce a time series down to one number. For example, to calculate the available memory percentage for a group of servers we need to sum all available memory for all servers and sum total memory for all servers and then divide the available memory total by the total memory total. The way to do this in Grafana is to create two queries, A for the total and B for the subtotal and then divide B by A. Graphite has a function divideSeries that you can use for this. Then hide A you can see that is grayed out below and use B for the SingleStat value. The divideSeries function can be used in a Graph panel too, as long as the divisor is a single time series for example, it will work for the sum of all servers but not when grouped by server. In this case, divideSeries will not work. One way to solve this is to use a different graphite function called reduceSeries. In the example, there are two values, capacity the total and usage the subtotal. First, a groupByNode function is applied, this will return a list with the two values for each server e. The mapSeries and reduceSeries take this list and for each server applies the asPercent reduce function to the two values. The result is a list of percentage totals per server. The reduceSeries function can also apply two other reduce functions: a diff function and a divide function. Another function worth checking out is the AsPercent function which might work better in some cases. The example below uses the same two query technique that we used for divideSeries but it works with multiple time series! I did not know them before so I think they will help others too.

Grafana gauge query exampleIf you need a solution for querying and visualizing time series and metrics probably your first choice will be Grafana. At present it is becoming very popular to integrate with InfluxDB as a data source. This is a solution specifically designed for storing real-time metrics and events and is very fast and scalable for time-based data. It also includes a metrics service with gauge and counter support. Gauge records a single value, counter records incremented or decremented value in all previous steps. We can also define our own custom metrics. Spring Boot has not build-in metrics exporter for InfluxDB, so we have add influxdb-java library into pom. The metrics should be read from Actuator endpoint, so we should declare MetricsEndpointMetricReader bean. We can customize exporting process by declaring properties inside application. In the code fragment below there are two parameters: delay-millis which set metrics export interval to 5 seconds and includeswhere we can define which metric should be exported. The first step is to create InfluxDB data source. Now, we can create our new dashboard and add some graphs. Of course there is also a possibility of writing text queries, but not all of query language features are available. On the second picture below you can see enlarged graph with average REST methods processing time. We can always implement our custom service which generates metrics sent to InfluxDB. Below, there is example of GaugeService usage, where the random value between 0 and is generated in ms intervals. This feature is available from 4. If you have already created graph for gauge. There you can define alerting condition by selecting aggregating function for example avg, min, maxevaluation interval and threshold value. For my sample visible in the picture below I selected alerting when maximum value is bigger than 95 and conditions should be evaluated in 5 minute intervals. After creating alert configuration we should define notification channel. There are some interesting supported notification types like email, Hip Chat, webhook or Slack. Then, add new notification for your alert sent to Slack in Notifications section. Like Like. Good job. You can also use cloud-based solution e. Like Liked by 1 person.

Learn about Grafana the monitoring solution for every database. Open Source is at the heart of what we do at Grafana Labs. If you use a password for your data sources please read the upgrade notes. Check out the demo dashboard of some the new features in v6. Data sources now store passwords and basic auth passwords in secureJsonData encrypted by default. Existing data source with unencrypted passwords will keep working. Read the upgrade notes on how to migrate existing data sources to use encrypted storage. To mitigate the risk of Clickjackingembedding Grafana is no longer allowed per default. Read the upgrade notes for further details of how this may affect you. To mitigate the risk of sensitive information being cached in browser after a user has logged out, browser caching is now disabled for full page requests. Grafana v6. The main difference is that the Bar Gauge uses both horizontal and vertical space much better and can be more efficiently stacked both vertically and horizontally. Read the preview article to learn more about the design and features of this new panel. Retro LED display mode. Gradient mode. We have been working on improving table support in our new react panels Gauge and Bar Gauge and this is ongoing work that will eventually come to the new Graph and Singlestat and Table panels we are working on. But you can see it already in the Gauge and Bar Gauge panels. Without any config, you can visualize any number of columns or choose to visualize each row as its own gauge. This has been one of the most requested features for many years and is now finally here! Lazy loading of panels means Grafana will not issue any data queries for panels that are not visible. This will greatly reduce the load on your data source backends when loading dashboards with many panels. Sometimes your panels do not need a title and having that panel header still take up space makes singlestats and other panels look strange and have bad vertical centering. In v6.

Hi, It's will be nice if we could use a variable as min and max value in gauge panel. In my case, I monitor utilization of data and have data formatted like this :. So "space used" is the query result and "Quota" should be Max value of gauge. Ohh, i want exact this! I wan this too! Number of user login inside an application Maximum value : Grab the highest value of user login since 7 days. I'd love this feature to be able to display the number of "up" devices out of a total instead having 2 individual stats, "up" and "down". Any defined milestone? Last update was for 4. It would be nice to see this get reworked into a new milestone since v4. So it would really be nice to be able to define a separate query for getting the max value, shouldn't be too hard! Hello, can this be done with a custom plugin? To the people having to adjust every gauge when something like disk space changes, why not display a usage in percentages? I can still see how this feature request is an improvement to that, but I thought it could help in the meantime. Today, we end up sprinkling tons of repeat graphs for the same variable just to get the numbers clearly displayed. Perhaps this is the thing where this needs to be done? Although, what I'm after is mainly a way to get a dynamic max value
