Observability is vital when it comes to producing and maintaining modern
applications. Ironically, there are still a lot of obscurities when it comes to
Monitoring and observability are often mixed up, which is not quite right. This
could be due to the level of abstraction surrounding the concept. Many search
results providing an answer to "what is observability?" are tailored to fit
marketing purposes. DevOps.com identified this trend
Monitoring is tooling or a technical solution that allows teams to watch and understand the state of their systems. Monitoring is based on gathering predefined sets of metrics or logs.
Observability is tooling or a technical solution that allows teams to debug their system actively. Observability is based on exploring properties and patterns not defined in advance.
The main difference lies in the fact that monitoring requires prediction -
engineers must configure a monitor to check if a specific thing goes out or not.
Observability allows you to spot performance trends and issues and unexpected
service behavior, so it helps you to find places where monitoring is needed.
Observability platform vs. observability tool
Logs, Metrics, and Traces, also known as the three pillars of observability,
enable developers to reach observability in complex distributed services. Thus,
log management, monitoring, or tracing applications are observability tools that
offer only a partial insight due to how platforms handle ingested data.
Another issue is that it's still a relatively new concept. Most vendors offering
such platforms have been on the market for years, but the term observability
surfaced only recently. This can be illustrated with market giants like Datadog
and New Relic since they do not offer the same "observability" while both being
10 Best Observability Tools in 2023:
Logtail is a log management solution based on ClickHouse, which allows it to be

monitoring compliance with standards like HIPAA or GDPR)
Dynatrace is an end-to-end observability platform offering an entire
observability toolkit from Infrastructure monitoring, Log management, and APM.
Dynatrace's Application monitoring is one of the best available. It allows you
to monitor the performance and security of cloud applications. It's also fairly
easy to work with, thanks to the One-Agent data collection and agent
configuration directly from the Web UI. You can find more information about
Dynatrace in our comparison article with Datadog, where
we deployed, tried, and tested both.
A feature that stands out: Davis, the AI-engine
Davis, the AI engine from Dynatrace, handles most of the data processing and
provides insights extracted from data across the stack. This can make the
pricing a bit confusing, mainly due to the Davis-unit pricing.
4. New Relic
New Relic is an observability platform with a toolkit divided into 16 main tools
covering everything from Infrastructure monitoring, Logging, APM, and RUM to
Security monitoring. It's been on the market since 2008 and is one of the most
renowned platforms out there. New Relic is mainly praised for top-notch APM
features, well integrated into the observability stack, and fairly easy
maintenance. Needless to say, really mastering the platform is not an easy or
cheap task. If you want to learn more about New Relic, make sure to check out
our Datadog vs. New Relic Comparison.
