9 Best Cloud Logging Services for Log Management, Analysis, Monitoring & More [2021 Comparison]

Rafal Kuć Rafal Kuć on

Log management stopped being a very simple operation quite some time ago. Long gone are the “good old days” when you could log into the machine, check the logs, and grep for the interesting parts. Right now things are better. With the observability tools that are now a part of our everyday lives, we can easily troubleshoot without the need to connect to servers at all. With the right tools, we can even predict potential issues and be alerted at the same time an incident happens.

This is where log analysis tools come into play – especially cloud logging services. Cloud logging services aim to provide a service that lets you ship your logs and store them securely, aggregate, and analyze them so that you can take actions based on the current and historical data and correlate it with other information that is part of the whole observability solution – like metrics and traces.

If you’re interested in such a solution, look no further. In this post, we’re going to compare some of the best cloud logging services available out there to help you get started.

Why Do You Need Cloud Log Management Services

In the modern software era, it is close to impossible to keep an eye on everything, especially in medium and large-scale systems. The number of systems, servers, and IoT devices that are a part of such systems makes it impossible to manually manage, monitor, and analyze their logs. Add to those different business requirements, different compliance requirements and we quickly run into a situation where a well configured and maintained log centralization solution is a necessity.

Keeping the data in-house with one of the available log management tools may seem like an easier and cheaper choice at first, but as the amount of data grows managing the data store used for logs becomes a job on its own. It is not unusual to have a dedicated team managing the clusters responsible for the whole observability pipeline – which logs are a part of.

The cost of housekeeping and managing the logs yourself can be mitigated to one of the commercial vendors that provide SaaS products that allow us to send, store, manage and analyze logs.

What Cloud Logging Service Will You Use?

Choosing the right cloud logging service is not a simple task. You need to look at the features that you need at the moment and that you may potentially need in the future. For example, your use case may require you to have the live-tail with filtering support, so that you can look for certain log events live. You may need to have alerting with anomaly detection so that unusual patterns can be caught and reported to the destination of your choice.

Yes, available ChatOps integrations are also important, because getting the alert to the destination that is close to the on-call person is crucial when issues happen. Those of us that are legally bound to keep data for auditing will require long-term storage, such as S3 compatible storage that can be configured and automatically used. The ability to connect logs with metrics is a crucial enabler for faster troubleshooting, shorter downtimes, and faster MTTR.

Finally, the price may be an important factor – the more logs you store, the higher the invoice will be and different vendors have different prices – for a similar amount of data.

Look for cloud log management solutions that:

  • Let you jump between logs and metrics easily and quickly. That’s one of the keys for faster troubleshooting and making your job and life easier.
  • Offer powerful log search syntax so you can more quickly and more easily find data you need.
  • Offer easy setup, save you time with out-of-the-box dashboards and alert rules.
  • Have attractive and flexible pricing. Avoid vendors whose pricing involves per-user and per-usage pricing because that will force you to start thinking about who, and how many people have access to your logs, which is a complication you do not need.
  • Can collect logs not only from various backend infrastructure, but also collect mobile application logs, for example.

Remember that migrating to another vendor may not be easy and may end up losing the possibility of searching through your data archive. Such migration will require reconfiguration of your log shipping software or even applications if you have chosen to ship the data directly from them. For large, highly distributed environments such operation can take a vast amount of time and is not negligible.

If you’re looking for a cloud logging service give Sematext Logs a try. Our log management service allows you to stay on top of your application, system, and platform logs. There’s a 14-day free trial for you to test all its functionalities. Give it a try!
