Using Google Stackdriver in Grafana

Grafana ships with built in support for Google Stackdriver. You just have to add it as a datasource and you will be ready to build dashboards for your Stackdriver metrics.

Adding the data source to Grafana

1. Open the side menu by clicking the Grafana icon in the top header.
2. In the side menu under the Dashboards link you should find a link named Data Sources.
3. Click the + Add data source button in the top header.
4. Select Stackdriver from the Type dropdown.
5. Upload or paste in the Service Account Key (JWT) file. See below for steps to create one.

NOTE: If you're not seeing the Data Sources link in your side menu it means that your current user does not have the Admin role for the current organization.

Name	Description
Name	The datasource name. This is how you refer to the datasource in panels & queries.
Default	Default datasource means that it will be pre-selected for new panels.
Service Account Key	Service Account File for a GCP Project. Instructions below on how to create it.

Authentication

Service Account Credentials - Private Key File

To authenticate with the Stackdriver API, you need to create a Google Cloud Platform (GCP) Service Account for the Project you want to show data for. A Grafana datasource integrates with one GCP Project. If you want to visualize data from multiple GCP Projects then you need to create one datasource per GCP Project.

Enable APIs

The following APIs need to be enabled first:

• Monitoring API
• Cloud Resource Manager API

Click on the links above and click the Enable button:

Create a GCP Service Account for a Project

1. Navigate to the APIs & Services Credentials page.

2. Click on the Create credentials dropdown/button and choose the Service account key option.

   

3. On the Create service account key page, choose key type JSON. Then in the Service Account dropdown, choose the New service account option:

   

4. Some new fields will appear. Fill in a name for the service account in the Service account name field and then choose the Monitoring Viewer role from the Role dropdown:

   

5. Click the Create button. A Json Web Token (JWT) file will be created and downloaded to your computer. Store this file in a secure place as it allows access to your Stackdriver data.

6. Upload it to Grafana on the datasource Configuration page.

Metric Query Editor

Choose a metric from the Metric dropdown.

To add a filter, click the plus icon and choose a field to filter by and enter a filter value e.g. instance_name = grafana-1

Aggregation

The aggregation field lets you combine time series based on common statistics. Read more about this option here.

The Aligner field allows you to align multiple time series after the same group by time interval. Read more about how it works here.

Group By

Group by resource or metric labels to reduce the number of time series.

Alias Patterns

The Alias field allows you to control the format of the metric names in the legend. The default is to show the metric name, labels and the resource. This can be long and hard to read. Using the following patterns in the alias field, you can format the metric name in the legend the way you want it.

Example Pattern: {{metric.type}} - {{metric.labels.instance_name}}

Example Result: compute.googleapis.com/instance/cpu/usage_time - server1-prod

Table Format / Raw Data

Change the option Format As to Table if you want to show raw data in the Table panel.

Templating

Instead of hard-coding things like server, application and sensor name in you metric queries you can use variables in their place. Variables are shown as dropdown select boxes at the top of the dashboard. These dropdowns makes it easy to change the data being displayed in your dashboard.

Checkout the [Templating]({{< relref "reference/templating.md" >}}) documentation for an introduction to the templating feature and the different types of template variables.

Query Variable

If you add a template variable of the type Query, this allows you to query Stackdriver for things like metric names and filter keys. The Stackdriver datasource provides the following functions you can use in the Query input field:

Name	Description
metrics(project_id, filter expression)	Returns a list of metrics matching the filter expression.
label_values(project_id, path to label name, filter expression)	Returns a list of label values matching the filter expression.
groups(project_id)	Returns a list of groups.

Using variables in queries

There are two syntaxes:

• $<varname> Example: rate(http_requests_total{job=~"$job"}[5m])
• [[varname]] Example: rate(http_requests_total{job=~"job"}[5m])

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 a word. When the Multi-value or Include all value options are enabled, Grafana converts the labels from plain text to a regex compatible string, which means you have to use =~ instead of =.

Annotations

[Annotations]({{< relref "reference/annotations.md" >}}) allows you to overlay rich event information on top of graphs. You add annotation queries via the Dashboard menu / Annotations view.

Configure the Datasource with Provisioning

It's now possible to configure datasources using config files with Grafana's provisioning system. You can read more about how it works and all the settings you can set for datasources on the provisioning docs page

Here is a provisioning example for this datasource.

apiVersion: 1

datasources:
  - name: Stackdriver
    type: stackdriver
    jsonData:
      tokenUri: https://oauth2.googleapis.com/token
      clientEmail: stackdriver@myproject.iam.gserviceaccount.com
    secureJsonData:
      privateKey: "<contents of your Service Account JWT Key file>"
