Google Cloud Load Balancing

Ship Google Cloud platform load balancing logs from Pub/Sub to Logstash

Step 1 - Confirm Google Cloud Load Balancing Logs

If you already have logging enabled for your Google Cloud load balancing you can skip to step 2. Instructions on how to configure Google Cloud load balancing can be found here.

Google Cloud provides a basic log viewer, in order to get the logs into your Stack we need to configure a Pub/Sub sink, from where Logstash can collect the logs.

Step 2 - Export Logs to Google Pub/Sub

Having located the logs you wish to export, choose the option to CREATE SINK. You will be prompted with the following options. Choose the Cloud PubSub topic option.

Select sink service

You will be then be prompted for:

Sink name
Sink Service (choose Pub/Sub)
Sink Destination (choose create new Cloud Pub/Sub topic)

Fill in edit sink form

Create new Cloud Pub/Sub topic

Once you've entered these details choose create sink. This will ensure that the logs you have specified are directed to the Pub/Sub sink

Step 3 - Create Google Pub/Sub

Locate your newly created Pub/Sub topic.

Find topic in Topics menu

On your topic, click the ellipsis to the right.

Go to topic settings

Enter a suitable subscription ID and make sure delivery type is set to pull.

Scroll to the bottom of the page and press create.

Create subscription for topic

Step 4 - Create Service Account

Visit service accounts and choose the project you want to add the service account to. This will be used to retrieve logs from the GooglePubSub and send to Logstash.

Select create a new service account.

Create new service account

Give your service account a name and add the relevant Pub/Sub permissions for the service account.

Configure new service account

Now we need to create a key for the service account, this will be used by Logstash to access the service account in order to retrieve logs.

Click into the newly created service account.

View new service account

Choose the option to add a key and then select create a key option, remember to download the service key as json when prompted.

Add key using dropdown

Step 5 - Configuring Logstash

To start pulling Logs from the Google Cloud Platform pub/sub to your Stack a Logit.io engineer will configure the Logstash input for you. You can share the following details with our engineers securely over intercom using the button below.

project_id => The complete ID of your project
topic => The name of the topic you created
