Quickstart for Compute Engine

This page shows you how to monitor a Compute Engine virtual machine (VM) instance with Cloud Monitoring. If you want to monitor an Amazon EC2 VM instance, see Quickstart for Amazon EC2.

In this quickstart, you do the following:

  1. Create a Compute Engine VM instance.
  2. Install Apache HTTP Server.
  3. Install the Cloud Monitoring and Logging agents.
  4. Create an uptime check with an alerting policy.
  5. Create a custom dashboard and chart.
  6. View your logs.
  7. Clean up.

Before you begin

To use Cloud Monitoring, you need to create a Google Cloud project, enable billing for your project, and associate your project with a Workspace.

To create a project and enable billing, do the following:

  1. In the Cloud Console, go to New Project:

    Create a New Project

  2. In the Project Name field, enter Quickstart and then click Create.

  3. Go to Billing:

    Go to Billing

  4. Select your Quickstart project if it isn't already selected at the top of the page.

  5. You are prompted to choose an existing payments profile or to create a new one.

Create a Compute Engine instance

  1. In the Cloud Console, go to Compute and then select Compute Engine:

    Go to Compute Engine

  2. To create a VM instance, click Create.

  3. Fill in the fields for your instance as follows:

    • In the Name field, enter lamp-1-vm.
    • In the Machine type field, select Small.
    • In the Firewall field, select both Allow HTTP traffic and Allow HTTPS traffic.

    Leave the rest of the fields at their default values.

  4. Click Create. Wait a couple of minutes for your instance to launch on the VM Instances page.

  5. To open a terminal to your instance, in the Connect column, click SSH.

  6. Update the package lists on your instance.

    sudo apt-get update
  7. Set up the Apache2 HTTP Server.

    sudo apt-get install apache2 php7.0
  8. Open your browser and connect to your Apache2 HTTP server by using the URL http://[External IP]. Replace [External IP] with the external IP address of your Compute Engine instance. You see the Apache2 default page:

    Display the Apache2 default page.

Install agents

The Cloud Monitoring and Logging agents pass logs and metrics from your VM instance to Monitoring and Logging:

  1. Switch to the terminal connected to your VM instance or create a new one.

  2. Install the Cloud Monitoring agent.

    curl -sSO https://dl.google.com/cloudagents/install-monitoring-agent.sh
    sudo bash install-monitoring-agent.sh
  3. Install the Cloud Logging agent.

    curl -sSO https://dl.google.com/cloudagents/install-logging-agent.sh
    sudo bash install-logging-agent.sh --structured

    The --structured flag lets the Logging agent send structured data to Cloud Logging. For more information, see Structured logging operations.

Create an uptime check

Uptime checks verify that your web server is accessible from locations around the world. The alerting policy controls who is notified if the uptime checks should fail.

To create an uptime check, do the following:

  1. Go to Monitoring:

    Go to Monitoring

    The first time you access Monitoring for a Google Cloud project, Monitoring creates a Workspace and associates it with your project. This process is automatic unless you have a multi-project Workspace. In this case, a dialog appears that asks you to select between creating a Workspace and adding the project to an existing Workspace. Select the option to create a Workspace.

  2. If you see the invitation Create an Uptime Check on the dashboard, then click it. Otherwise, go to Uptime Checks and then select Create Uptime Check.

  3. Fill in the following fields for the new uptime check:

    • In the Title field, enter My Uptime Check.
    • In the Check type menu, select HTTP.
    • In the Resource Type menu, select Instance.
    • In the Applies To field, enter Single, lamp-1-vm.
    • Leave the other fields with their default values.

      Display of new uptime check dialog with default fields.

  4. To verify that your uptime check is working, click Test. If you see a "Connection error - refused" message, you might have not installed the Apache HTTP Server or you might have specified the HTTPS check type rather than HTTP. For other errors, see Verify your uptime check.

  5. Click Save. The confirmation dialog displays:

    Display of the Uptime Check Created dialog.

Create an alerting policy

  1. In the Uptime Check Created pane, click Create Alerting Policy.

  2. In the Untitled Condition field, enter a title for the alert policy condition. All other fields are in the conditions pane are automatically populated from the uptime check you created.

    Display of the create condition dialog with default settings.

  3. Click Save.

  4. Enter My Uptime Check Policy as the Name for the alerting policy.

    Display of the create new alerting policy dialog with default settings.

  5. (Optional) To configure an email notification, click Add notification channel, select Email from the menu, enter your email address, and then click Add.

  6. Click Save. You see a summary of the policy.

Create a dashboard and chart

To display the metrics collected by Monitoring, create a chart and a dashboard:

  1. Go to Monitoring

    Go to Monitoring

  2. Select Dashboards and then select Create dashboard.

  3. Enter Quickstart dashboard as the name for the dashboard and click Confirm.

  4. Click Add Chart.

  5. Ensure the Metric tab is selected.

    Display the add chart dialog with default settings.

  6. Under Find resource type and metric heading, click instance, cpu, usage, etc.:

    • Select G​C​E VM Instance for the resource type.
    • Enter CPU, and then select CPU load(1m) for the metric.
  7. Click Save.

    Display of the configured chart.

  8. To create a second chart, click Add Chart.
