Observability vs APM vs Monitoring Comparison

APM is a tool that monitors application performance and user experience by tracking metrics like load and KPIs. It allows seeing how applications are used by real users and identifying problems that impact sales or brand experience. Observability aggregates data from logs, metrics, and traces to assess overall system health, while APM directly focuses on gauging user experience. Both ensure good user experience but in different ways - APM actively collects data related to response time, while observability passively examines various data sources. Monitoring tracks predefined metrics over time to understand system status, but observability analyzes related data to determine the root cause of issues.
Observability vs APM vs Monitoring Comparison
- 2. What is APM? As its name suggests, application performance monitoring (APM) is a tool to locate the source of application performance issues. Even so, APM goes well beyond what might be expected from basic performance monitoring offerings. APM is often used with a modern application as a way of assessing the user experience. At a general level this might mean tracking an application's load, along with KPIs. Doing so not only enables an organization to monitor the user experience; it also provides visibility into how that experience changes as an application's workload increases.
- 3. What is use of APM? What makes APM so powerful are the abilities to: •See exactly what your applications are doing while interacting with real users •Discover problems that may be limiting sales, keeping customers from using your product successfully, or damaging your brand experience •Identify when your applications are struggling and why •Identify where applications are wasting resources so you can tune to reduce expenses and increase availability •See historical trends and proactively prevent service outages
- 4. Benefits of APM? 1.Understand how your applications are being used: how many users are using the system at once? for how long? where are they having problems? are specific subsets of users poorly served? what is causing a problem for a specific customer? 2.Understand your requests: how much traffic are you receiving? from where? how fast are you responding? which aspects of the application are slow? 3.Understand your resource usage: how much CPU are you using? is your application leaking memory? are processes bloated because of poor code execution? are you running unnecessary database queries? will your application scale gracefully with growth? 4.Track how things are changing: what are the impacts of new deploys? are you introducing new problems? are you fixing the problems you think you are? 5.Know what isn't working: is your application experiencing errors?
- 5. What is observability? Like APM, observability is a method used to determine the overall health of complex systems and IT workloads. While APM collects data for KPIs, observability aggregates data from various sources to paint a picture of the system's overall health. Observability data sources : 1.Metrics. These generally refer to raw performance data. Metrics might represent anything from the number of CPU cycles being consumed at a given moment to the amount of time an e-commerce application takes to complete a credit card transaction. 2.Traces. These help to monitor the interaction between the components making up a complex system. A network trace, for instance, can track the path packets take to their destination. An application trace can also track how the application's components are used. 3.Logs. Coming in many forms, logs can be informational or contain errors or warnings. An informational log entry might be generated, for example, when a process is created, while an error event might be added to a log if that process were to terminate unexpectedly.
- 6. What are the differences between APM and observability? APM and observability tools can ensure a good user experience, but they work toward that goal in different ways. Observability takes the data that exists in logs, metrics and traces, and then uses that information to form an overall health assessment. Even though the goal is to ensure a good user experience, observability doesn't directly focus on gauging the user experience. Instead, observability applies the principles of control theory, which essentially state that it's possible to understand what's going on with a system by examining its inputs and outputs. Examining logs, metrics and traces collectively enables a tool to assess the application's health, which can then be used to determine if users are having a good experience.
- 7. What are the differences between APM and observability? APM works by actively collecting internal state data and data related to application response time. This data correlates directly to the user experience. Some APM tools are designed to monitor the underlying infrastructure in addition to the application itself, which enables the tool to perform root cause analysis when problems occur.
- 14. Monitoring vs Observability The bottom line in the observability vs monitoring debate is that they’re both vital when managing microservice-based applications. While monitoring tracks the system’s health of your application, observability tells you why it’s performing a certain way. It could be argued that monitoring is simply a subset of observability or a part of the process. The issue with starting with monitoring alone is that without observability, you won’t be able to gain the data needed for contextualized analysis. Observability encompasses monitoring and allows DevOps professionals to understand the root cause of an error and how it is affecting your system. Thankfully, there are tools like Instana that collect and evaluate this data to make sense of your multicloud environment.
- 15. Monitoring vs Observability Monitoring is tooling or a technical solution that allows teams to watch and understand the state of their systems. Monitoring is done by gathering predefined sets of metrics or logs. Observability is tooling or a technical solution that allows teams to debug their system actively. Observability is exploring properties and patterns not defined in advance
- 16. Monitoring vs Observability Monitoring focuses on a set of predefined system health metrics and how they change with time. Logging provides separate data but is viewed in isolation generally. Monitoring helps one understand "WHAT" is changing. This is helpful when the points of failure of a system are well understood, and there are fewer unknowns. Observability is the ability to understand a system's internal state by analyzing the data it generates, such as logs, metrics, and traces. Observability takes monitoring to the next level, by not only highlighting "WHAT" is changing, but analyzing the related data sets to answer "WHY" did some metrics change and identify the root cause. Observability becomes especially important in distributed systems, where there could be many failures, and it's impossible to foresee the point of failures in advance.
- 18. Similarities between Observability and Monitoring • Fix Issues By locating and resolving problems, observability and monitoring both contribute contribute to the system's continued functionality and dependability. • Rely on Data Both use data to identify the problem, which is another characteristic they share. A share. A deeper exploration of both of these locations reveals differences. • Demand a Deeper Understanding Furthermore, whether you try to implement monitoring or observability, a comprehensive understanding of the system is required. Particularly in the case of case of monitoring because, in contrast to observability, it does not assist you in you in establishing connections between various system occurrences.
