Cloud Monitoring Sample
Simple command-line program to demonstrate connecting to the Google Monitoring API to retrieve API data.
listresources demonstrates how to read the Google Cloud Monitoring v3 environment such as
Monitored Resources and Metric Descriptors.
custommetric demonstrates how to create a custom metric, write a timeseries value to it,
and read it back.
Prerequisites to run locally:
Create local credentials by running the following command and following the oauth2 flow:
gcloud beta auth application-default login
Set Up Your Local Dev Environment
go get the code and change into the directory:
go get -u github.com/GoogleCloudPlatform/golang-samples/monitoring/...
cd $GOPATH/src/github.com/GoogleCloudPlatform/golang-samples/monitoring
To run the example that prints the environment, run:
go run listresources/*.go <your-project-id>
To run the example that creates a custom metric and writes to it, run:
go run custommetric/*.go <your-project-id>
Running on GCE, GAE, or other environments
On Google App Engine, the credentials should be found automatically.
On Google Compute Engine, the credentials should be found automatically, but require that you create the instance with the correct scopes.
gcloud compute instances create --scopes="https://www.googleapis.com/auth/cloud-platform,https://www.googleapis.com/auth/compute,https://www.googleapis.com/auth/compute.readonly" test-instance
If you did not create the instance with the right scopes, you can still upload a JSON service account and set GOOGLE_APPLICATION_CREDENTIALS as described below.
Using a Service Account
In non-Google Cloud environments, GCE instances created without the correct scopes, or local
workstations if the gcloud beta auth application-default login command fails, use a Service
Account by doing the following:
- Go to API Manager -> Credentials
- Click 'New Credentials', and create a Service Account or click here.
- Download the JSON for this service account, and set the
GOOGLE_APPLICATION_CREDENTIALSenvironment variable to point to the file containing the JSON credentials.
export GOOGLE_APPLICATION_CREDENTIALS=~/Downloads/<project-id>-0123456789abcdef.json
