Frequently Asked Questions About Google Cloud Monitoring

What are Google Cloud Monitoring Tools?

Google Cloud monitoring tools are tools that can be used to monitor the performance and availability of components of the Google Cloud Platform, a suite of cloud computing services offered by Google.

These can range from simple service availability monitors to more sophisticated tools that can deliver deep insight into the performance of your applications and services running or hosted on the GCP.

Keep in mind that the GCP is composed of literally tens of services, and most tools aren’t capable of monitoring every single one of them. However, most support the “core” services, like the Compute Engine, Cloud Storage, Filestore, or Kubernetes Engine. We recommend that you check with the developer of each tool for more information on specific features.

Google offers its own GCP monitoring solution called “Google Cloud Operations“, formerly known as Stackdriver. However, in this article, we are focusing on third-party tools, which may offer features that better integrate with a heterogeneous IT infrastructure, like multi-cloud or hybrid monitoring, application performance monitoring (APM), and more.

Why Should You Invest in Google Cloud Monitoring?

There are many reasons to invest in Google Cloud Monitoring. Here are five of them, in no particular order.

  1. Performance optimization: continuous monitoring can help you pinpoint issues and identify opportunities for optimization that will improve the performance of your infrastructure, sometimes without the need for hardware or resource upgrades.
  1. Security: monitoring allows you to spot early signs of uncommon behavior or usage patterns indicative of an intrusion attempt or ongoing attack. This will give you time to react and deploy countermeasures before a data breach occurs.
  1. Resource allocation: find out where resources are being underutilized or overutilized, allowing you to redistribute them according to real needs to ensure the most effective usage of your systems.
  1. Proactive maintenance: monitoring allows you to detect and fix potential issues before they become critical and result in outages that may affect the performance of your applications or even the profitability of your business.
  1. Regulatory compliance: businesses that handle sensitive information, like financial or healthcare data, need to meet strict regulatory standards that specify how this information is stored and handled. Monitoring will allow you to prove compliance with these standards and secure approvals that may be crucial to keep your business running.

What to Look for When Choosing Google Cloud Monitoring Tools?

Broadly speaking, there are 5 main features you need to look out for when choosing Google Cloud monitoring tools. Keep in mind that this may vary according to your specific needs.

  • The capability to monitor many aspects of your Google Cloud infrastructure at once.
  • A centralized display of information from many sensors for better observability.
  • Customizable alerts and automated notifications when alerts are triggered.
  • Native and automated reporting features, so you can keep co-workers and management “in the loop”.
  • A free trial period, so you can attest to how the tool works with your network infrastructure.

How to do Google Cloud Monitoring?

There is no “right” way to do it, as it all depends on your needs. There are many Google Cloud monitoring tools, from as many different vendors, which may focus solely on a single aspect of the task or offer this capability as a subset of a broader range of features. We present a few of them below, in no particular order.
