Delivering modern software applications requires complex assemblages of web servers, databases, CDNs, ephemeral containers, load balancers, and so much more. Tools like New Relic provide instrumentation that gives you deep visibility into your applications and their underlying infrastructure, but sometimes you need to look at the logs created by these systems.

Logs hold chronological lists of events about performance, security, activity, and more that IT admins, DevOps teams, site reliability engineers, and software developers use every day to troubleshoot and audit systems. Logs need to be parsed, normalized, and combined; log data needs to be exposed so dev and ops teams can perform live ad-hoc searches, set up log-level alerts for proactive troubleshooting, and secure specific historical reports in order to gain insight into trends in system performance, usage, and security.

Logs contain vast numbers of events that teams need to combine, sift, sort, analyze, and be alerted on. Thankfully, there are many tools designed to help modern software teams get the most out of their logs. We looked at 15 lead logging tools—including full-service solutions and single-purpose tools—to help you choose the right ones to meet your logging needs.

Full-service logging solutions

The tools in this category come with a wide range of functionality designed to cover the majority of logging use cases, including advanced searching, archiving, and alerting.

Logs contain critical insight into the performance of your applications, databases, and infrastructure. Every logging tool has its own strengths, weaknesses, and learning curves, so the goal is to find the one that best matches the needs of organization.

In fact, it’s likely that you’ll want more than one—think Fluentd + Elasticsearch. Or consider how to complement your logging tool with New Relic for full-stack visibility into your applications, infrastructure, and—most importantly—your customer experience.
