# GCP Cloud Monitoring

> Google Cloud monitoring for metrics, logs, and alerts

## Overview

Connect GCP Cloud Monitoring to give TierZero access to your Google Cloud metrics, logs, and alerting data. TierZero queries Cloud Monitoring during investigations to analyze service health and correlate events.

## Prerequisites

* A [GCP integration](/integrations/gcp) configured with a service account
* Cloud Monitoring enabled in your GCP project

## Setup Instructions

### Step 1: Configure GCP Integration

If you haven't already, set up the [GCP integration](/integrations/gcp) first. Cloud Monitoring access is provided through the GCP service account.

### Step 2: Navigate to Integration Settings

1. Go to **Settings → Integrations**
2. Click **Connect** next to GCP Cloud Monitoring
3. Select the GCP project(s) to monitor

### Step 3: Verify Access

TierZero will validate access to Cloud Monitoring using the configured service account.

## Required Roles

The service account must have:

* `roles/monitoring.viewer`: Read metrics and alerting policies
* `roles/logging.viewer`: Read Cloud Logging data

## What TierZero Accesses

* **Metrics**: Custom and system metrics, timeseries data
* **Logs**: Cloud Logging entries and log-based metrics
* **Alerts**: Alerting policy configurations and incidents

## Security

* Access through GCP service account impersonation
* Read-only roles only
* Revoke by removing the monitoring/logging roles from the service account

## Troubleshooting

### Missing Metrics

* Verify the service account has `roles/monitoring.viewer`
* Check that metrics exist in the selected GCP project
* Ensure the correct project is selected in the integration settings
