Grafana custom variable key value

Current implementation of custom template variable in grafana only expects cofiguration as a comma separated list of values, which is used later in dropdown widget component. This works nicely in simple cases, but not if one wants to display user-friendly text in dropdown and use internal var value in queries and human-friendly - in label or title.

With a proposed extended format missing attribute can be set to an empty string or entered value string in such case. I think you can do what you want already. If you use MySQL as the data source for your template variable then you can do something like this:. Thank you, this looks like a partial solution though.

Which version of Grafana supports this template var syntax? Does it work with MySQL datasource only? It only works with the MySQL data source although Clickhouse could easily implement this feature which was released in Grafana 4.

Postgres which will be included in 4. Interesting stuff. What should I do to make it work? Oh, you are right - sorry about leading you down the wrong path. I have the same request for SqlServer. After define the mytest query variable, how can i access it in my sql? Docs Grafana. You can create a dummy MySQL data source, you do not need a db. Hope that clears everything up. Not sure if that is exactly what you are looking for. Using Grafana v4. Thanks very much. Finally ,I found the solution.

When enabled this feature will allow you to specify an tags query and a tags value query for a template variable. I was just about to post a feature request for something like that.

Might be very usefull. This looks awesome! I pulled down the latest nightly build but i having trouble working out how to use the feature with influxdb 0. Never mind i worked it out for others knowledge, and works as i expect based on description above. If i could just assign arbitrary sets of variables arbitrary tags in the GUI that'd be great for my use case, without having to create fake 'metrics' in the graphite database. Ah, just realized i could select a different datasource for the template variable.

Still, might be nice to be able to assign in the grafana GUI, since it's really a presentation layer thing. Finally got to try this feature and it's not quite what I expected I rather thought about what benh57 was saying, just pick up a few different values, say that this is now a group and give it a name.

Here is a very simple use case. Now, I want to group them, and see "Load average" for backend servers only for example, or "Memory free" graph for database servers only and so on.

Use Case: You may store metrics based on an 'ID' property but wish to have the template variable selection UI use a more human friendly label.

Configuration

I was thinking an initial implementation could be adding a config value in the dashboard JSON that defines the mapping function. UI support could be added later to handle more trivial mappings with pre built mapping functions e. You could do this with scripted dashboards. I too could use at least a simpler version of this.

In my scenario I want to select an entity name in the variable dropdown CustomerName1, CustomerName2, etc. Merging from This is especially common when using repeated rows and a custom variable to reduce duplication, but the top level metrics may not be user-friendly. One could potentially support this for queried template values e. Regex support already exists, but it applies to both the value used and the label.

Having it used for the value only would be valuable. For example, if a graphite query expands kafka. But when used in the actual panels, the prefix should be included. This can be worked around in Grafana 2. Once these "label" values exist, it would be useful to be able to access them inside the panels as well. Either we can make it use the label by default if embedded in a title fieldor perhaps with some alternate syntax e. Can this be closed? Is this possible for the 3. It looks like a feature many people are waiting for.

Including me You can use this. The options in the dropdown will have a text and value that allows you to have a friendly name as text and an id as the value. An example query with hostname as the text and id as the value:. Because graphite can not store Chinese character. So we have to use English in Graphite, but we would really like to show the Chinese in the grafana dashboard, so the user experience would be much better.

The first variable lists all possible IDs value while the second variable lists the name display text that matches the ID. It's not the ideal or pretty, but it does the trick.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Sign in to your account. What do you think about implementing additional template variable type in key-value s format? The issue title is not very accurate i thinkbecause the current templating system i key value, the text you see when you pick a variable value is not the same as the underlying value for example for All.

No, but I succesfully use it for many different cases. The problem is that I would like to manually describe groups apart from the metrics inspection which don't contain required piece of information, e. Is this PR solved for your case? Do you have a plan to merge the PR?

Open Source is at the heart of what we do at Grafana Labs. Variables allows for more interactive and dynamic dashboards.

Using AWS CloudWatch in Grafana

Instead of hard-coding things like server, application and sensor name in your metric queries you can use variables in their place. Variables are shown as dropdown select boxes at the top of the dashboard.

These dropdowns make it easy to change the data being displayed in your dashboard. A variable is a placeholder for a value.

You can use variables in metric queries and in panel titles. Why two ways? The first syntax is easier to read and write but does not allow you to use a variable in the middle of word.

How To Setup A Grafana Dashboard Step By Step

Use the second syntax in expressions like my. Before queries are sent to your data source the query is interpolatedmeaning the variable is replaced with its current value.

During interpolation the variable value might be escaped in order to conform to the syntax of the query language and where it is used. For example, a variable used in a regex expression in an InfluxDB or Prometheus query will be regex escaped. Read the data source specific documentation article for details on value escaping during interpolation. The formatting of the variable interpolation depends on the data source but there are some situations where you might want to change the default formatting.

For example, the default for the MySql data source is to join multiple values as comma-separated with quotes: 'server01','server02'.

In some cases you might want to have a comma-separated string without quotes: server01,server This is now possible with the advanced formatting options. Formats single- and multi-valued variables into a comma-separated string, escapes ' in each value by '' and quotes each value with '. Test the formatting options on the Grafana Play site. A variable is presented as a dropdown select box at the top of the dashboard. It has a current value and a set of options.

The options is the set of values you can choose from. This opens up a list of variables and a New button to create a new variable. This variable type is the most powerful and complex as it can dynamically fetch its options using a data source query.

Using the Regex Query Option, you filter the list of options returned by the Variable query or modify the options returned. One thing to note is that query expressions can contain references to other variables and in effect create linked variables.

Interpolating a variable with multiple values selected is tricky as it is not straight forward how to format the multiple values to into a string that is valid in the given context where the variable is used. Grafana tries to solve this by allowing each data source plugin to inform the templating interpolation engine what format to use for multiple values. Note that the Custom all value option on the variable will have to be left blank for Grafana to format all values into a single string.

Graphitefor example, uses glob expressions. InfluxDB and Prometheus uses regex expressions, so the same variable would be interpolated as host1 host2 host3.

Deafening silence in a sentence

Every value would also be regex escaped if not, a value with a regex control character would break the regex expression. Elasticsearch uses lucene query syntax, so the same variable would, in this case, be formatted as "host1" OR "host2" OR "host3".
