Logz.io has dedicated itself to encouraging and supporting cloud-native development. That has meant doubling down on support for AWS and Azure, but also increasing our tie-ins with Google Cloud Platform – GCP. Recently, our team added dozens of new integrations for metrics covering the gamut of products in the GCP ecosystem. 

GCP Metrics

Google Cloud comprises many services that generate their own metrics: BigQuery, Google Compute Engine, GKE (Kubernetes), Pub/SUB, and more. This data is exposed via dedicated namespaces for each of the services. With our new integration, you can easily ship metrics from all Google Cloud services using an easy-to-configure setup with Telegraf.

We’ve added over two dozen integrations for Logz.io Infrastructure Monitoring. Here is the full list:

Google AI Platform
Google API Gateway
Google Apigee
Google App Engine
Google Assistant Smart Home
Google BigQuery
Google BigQuery BI Engine
Google BigQuery Data Transfer Service

Telegraf

Telegraf is a common DevOps tool that enables you to ship a variety of metrics to Logz.io using a simple plugin configuration. In fact, many of Logz.io integrations have been made possible thanks to Telegraf (like Apache Solr, Influxdb, Haproxy, Puppet, and even YouTube to name a few). Let’s have a look at how this works for Google Cloud.

Configuring GCP Project Integration

To begin with, we need to set credentials in the GCP project that we will be collecting metrics from. In the Service account details screen we need to provide a unique name for the service account. 

On the next screen – Grant this service account access to project – we add the following roles: Compute Viewer, Monitoring Viewer, and Cloud Asset Viewer. Note that you must be a Service Account Key Admin to select Compute Engine and Cloud Asset roles.

Creating the Project Key

Now we need to create a key that we will use to authorize the data export. 

To create the key, we need to select our project in the Service accounts for project list, navigate to Keys > Add Key > Create new key, choose JSON as the type and save the file to a dedicated location on our local machine.

The next step is adding an environment variable to the key that we have just created. This is done by running:

export GOOGLE_APPLICATION_CREDENTIALS=<<PATH-TO-YOUR-GCP-KEY>>

Next, replace <<PATH-TO-YOUR-GCP-KEY>> with the path to the directory where we saved our key. 

Telegraf Setup

If you don’t have Telegraf on your machine, you will need to install it. As of this writing, the latest release is Telegraf v1.20.4. Just note that in this tutorial, examples will utilize Telegraf 1.19. You’ll need at least Telegraf v1.17 or higher to feed data into Logz.io. We install Telegraf as follows:

For Windows:

wget https://dl.influxdata.com/telegraf/releases/telegraf-1.19.2_windows_amd64.zip

After downloading the archive, extract its contents into C:\Program Files\Logzio\telegraf\.

For MacOS:

brew install telegraf

For Linux:

Ubuntu & Debian

sudo apt-get update && sudo apt-get install telegraf

RedHat and CentOS

sudo yum install telegraf

SLES & openSUSE

# add go repository
zypper ar -f obs://devel:languages:go/ go
# install latest telegraf
zypper in telegraf

FreeBSD/PC-BSD

sudo pkg install telegraf

Configuring Telegraf

Telegraf is a plugin-driven agent orchestrated by the telegraf.config file. The configuration file is located at C:\Program Files\Logzio\telegraf\ on Windows, /usr/local/etc/telegraf.conf on MacOS, and /etc/telegraf/telegraf.conf on Linux. We basically need two plugins for this job: input and output. 

The input plugin that we will be using across all Google Cloud services is inputs.stackdriver. This is what it looks like:

[[inputs.stackdriver]]
  project = "<<YOUR-PROJECT>>"
  metric_type_prefix_include = [
    "<<NAMESPACE>>",
  ]
  interval = "1m"

Here we need to define the name of our GCP project and a namespace that we will collect metrics from. We can specify as many namespaces as there are. The full list is available here.

The outputs plugin looks like this:

[[outputs.http]]
  url = "https://<<LISTENER-HOST>>:8053"
  data_format = "prometheusremotewrite"
  [outputs.http.headers]
     Content-Type = "application/x-protobuf"
     Content-Encoding = "snappy"
     X-Prometheus-Remote-Write-Version = "0.1.0"
     Authorization = "Bearer <<PROMETHEUS-METRICS-SHIPPING-TOKEN>>"

Here we need to replace <<PROMETHEUS-METRICS-SHIPPING-TOKEN>> with a token for our Logz.io Metrics account and <<LISTENER-HOST>> with the Logz.io Listener URL for our region, configured port 8053 for https traffic.

Running Telegraf

Our last step is to start Telegraf, which will automatically fetch the config file where we configured our logins. For MacOS, however, we need to explicitly provide the path to the config file. This is what we need to run, depending on our operating system:

On Windows:

telegraf.exe --service start

On MacOS:

telegraf --config telegraf.conf

On Linux:

Linux (sysvinit and upstart installations)

sudo service telegraf start

Linux (systemd installations)

systemctl start telegraf

Conclusion

That’s it. No additional configuration is needed, so now you can just navigate to your Logz.io account and see all your GCP metrics there. To assist you further, we created a dedicated set of instructions for each namespace, which you can find on our documentation page either in the app or on docs.logz.io. Just filter the list by Google Cloud and you will see all applicable documents.
