Best Cloud Monitoring Tools

One of the big advantages of cloud services is that your company doesn’t need to operate servers on your premises in order to run key business software and services. However, you still need to track the performance of service delivery.

If you signed up for cloud infrastructure because you don’t want to run your own servers or hire technicians, then the news that you need to monitor that infrastructure might be an unwelcome revelation. It would be tragic if you were expected to buy servers and hire IT staff just to monitor the IT assets that you subscribe to on the Cloud. However, there are plenty of cloud-based services that will help you to monitor your cloud-based system. You still don’t need to start up an in-house IT section.

Here is our list of the eight best cloud infrastructure monitoring tools:

Why monitor Cloud infrastructure?

The sales pitches of cloud services explain that the hosting company takes all of the hassles of running servers off your shoulders. So, why are you then expected to monitor them?

There is less pressure on you over the physical performance of cloud servers. However, there are still aspects of cloud services that are your responsibility. Ultimately, you are responsible for all of your business’s infrastructure and strategies. If your business fails, you carry the can. So, you have the duty to ensure that everything is working smoothly.

Many cloud services offer performance guarantees. However, if you read the fine print, you will notice that those “guarantees” are not backed with financial compensation, so they are aspirations, not guarantees. Where providers offer refunds for missed performance targets, they frequently specify that each customer has to put in a claim – the compensation is not awarded automatically. So, how do you know if performance drops to a level where you are entitled to a refund? You need to check the performance of the service yourself.

Automated cloud infrastructure monitoring

Fortunately, cloud infrastructure monitoring isn’t as time-consuming or as complicated as you might think. There are automated tools available that do all of the work for you. These tools incorporate an alerting mechanism. That means that you can be sure of peak performance unless you are notified otherwise.

Another big help when monitoring cloud services is that those resources are not based on your own premises and so the monitoring tools that you use don’t need to be hosted in your offices either. A lot of cloud infrastructure monitoring services are cloud-based themselves.

If you are monitoring a website, then the best location to launch your status checks from is anywhere in your office. No doubt, your staff and you check on the website many times a day. Part of the daily tasks of running a website involves referring to the pages on the site. So, manual availability checking is a built-in side benefit of those tasks. However, that doesn’t mean that your site is available everywhere in the world.

Increasingly, governments and internet service providers are blocking websites. As a site owner, you don’t know that your site might not be available in another part of the country or to subscribers to ISPs other than your own or in other countries. So, getting someone else to check whether your website is available from somewhere else is an important performance test. Your new page might load quickly on the computers in your offices, but how is it performing for visitors accessing it from the other side of the world?

There are many performance checks that can be carried out off-site and there are many cloud-based service providers that are ready to provide those monitoring systems.

The best cloud monitoring tools

Our methodology for selecting a cloud monitoring system

We reviewed the market for cloud monitoring tools and analyzed the options based on the following criteria:

  • Integration with native cloud platform event recording utilities
  • Monitoring platform services as well as application performance
  • Application and service dependency mapping
  • Performance alerts
  • SLA tracking
  • A free trial or a demo system to allow testing and assessment before paying
  • Value for money that is represented by a multi-level monitor at a reasonable price

Using this set of criteria, we looked for a range of monitoring services for cloud systems. We looked for monitoring services that are also cloud-based as well as on-premises systems for reaching out to the cloud.

You can read more about each of these tools in the following sections.

If a threshold gets tripped, you get notified by an alert, so you can leave AppOptics to monitor regular service and then get your attention when problems emerge.

As well as monitoring cloud servers, the AppOptics Infrastructure system is capable of supervising your on-premises servers, no matter where they are. This means that the package has on-premises/cloud hybrid monitoring capabilities. There aren’t many network monitoring features in AppOptics as it is designed with cloud services in mind; where the Internet takes the role of the network.

The dashboard for AppOptics is accessed through any standard web browser and so it is possible to check on server performance from anywhere. The main screen of the system offers a summary of all servers included in the monitoring. This gives a consolidated check on all servers, no matter where they are.

The AppOptics system can be customized by activating specialized service add-ons. These extra services are free and they are called inclusions. They add extra sensors to the monitoring system and specialist service screens to the dashboard. Two important examples of these add-ons are the integrations available for AWS and Azure.

Choosing a cloud monitoring tool

If you opted for cloud-based services, the chances are that you don’t have an IT department to look after technical resources. Therefore, you will need to focus your search on monitoring services that optimize those scarce technical human resources that you have.

If you are a sole trader or small business and you don’t have the volume of technical work that justifies hiring a specialist employee, you will need to find a cloud infrastructure monitor that anyone can set up and run. Such systems do exist.

When researching the market, we looked for cloud infrastructure monitors that are suitable for all types of business. We identified monitoring tools that work well for businesses with their own team of technicians and also tools that are suitable for use by sole traders with little to no technical expertise.

All businesses large and small need to save time and money, so we prioritized cloud infrastructure monitoring tools that automate supervision tasks and offer very good value for money.
