Let’s brief on Observability vs. Monitoring: Observability is proactive, flagging issues before they affect users. Furthermore, it provides teams with greater insight into how the system operates so that they can spot issues more precisely.
Observability typically draws its insights from logs, metrics and distributed tracing; however, advanced observability platforms go well beyond these basic functions by offering more comprehensive data and analysis for contextual indication and advanced anomaly detection.
What Is Observability?
Observability refers to the ability of a system to reveal its internal state by analyzing external outputs. To accomplish this task, data must be gathered from various sources – logs, metrics and traces are all essential – while instrumentation must also be utilized in order to gather telemetry from each container, service and application on an infrastructure for complete visibility across its entirety.
Gaining an in-depth view of your infrastructure helps you identify and understand incidents as they arise, providing visibility into when and why things went wrong. Furthermore, having this level of visibility gives you the confidence to modify applications and services without jeopardizing availability or performance risks, enabling faster product deliveries while improving end-user experiences and driving revenue growth.
Organizations with mature observability practices are more than two times as likely to report that their annual return on investment in observability is two or more times greater than organizations without such practices. Furthermore, observability has helped organizations enhance security by incorporating DevSecOps practices into its workflow and thus helping organizations improve security overall.
What is Monitoring?
Monitoring is the practice of collecting and analyzing predefined metrics to detect when systems aren’t performing as anticipated. Monitoring has been around since almost as long as computer technology itself and is an essential element of SRE/ops engineering.
Monitoring isn’t an effective tool for troubleshooting complex systems and requires SRE and ops engineers to manually sort through log data in order to gain contextual insights into performance issues – this process can be time consuming and laborious – especially on teams with multiple applications requiring monitoring.
Observability solutions enable automating log collection and analysis as well as providing actionable visualizations of key system metrics like latency and response times, suppress alert noise, pinpoint root causes quickly using distributed tracing, machine learning and metric/log correlation services, while at the same time eliminating alert fatigue using distributed tracing services or machine learning algorithms. By enabling observability across all layers of an IT stack, problem identification becomes faster and simpler while development processes that incorporate observability can detect application issues earlier and potentially avoid their production release.
Observability vs. Monitoring: Differences
Monitoring is focused on alerting when issues occur; observability seeks to understand why things go wrong and helps IT and DevOps teams identify problems more rapidly, improving user experiences faster. For it to work efficiently, however, observability requires ample data – both from complementary systems (like CI/CD pipelines or help desks) as well as from IT environments themselves in terms of logs metrics or distributed traces – in order to be effective.
These tools include log aggregators, metrics platforms and distributed tracing tools; these can help reduce time to resolve and detect new issues faster, helping prevent downtime and revenue loss. Observability tools offer all of the information necessary for understanding what’s happening within IT environments – pinpointing problems quickly while understanding their root cause helps resolve them swiftly; furthermore they make spotting patterns and relationships in complex multi-tiered infrastructure easier – a feature which sets them apart from simple monitoring solutions.
Monitoring vs. Telemetry
Monitoring is an indispensable tool for maintaining an efficient IT infrastructure. Utilizing data collection techniques, monitoring can detect potential problems early enough so you can take corrective actions as soon as they arise.
Observability goes beyond just monitoring. In order to detect and address problems in complex distributed systems, it takes more than simply keeping an eye on them. Observability solutions collect telemetry data from across the entire stack — application logs, metrics and distributed tracing — in order to detect issues that would otherwise go undetected.
Observability differs from traditional monitoring in that it provides context to collected data. While traditional monitoring collects and analyzes IT infrastructure data for spot checks, observability analyzes that same data with an eye toward debugging, troubleshooting, and diagnosing issues – for instance a monitoring solution might detect an issue with an IT service, but wouldn’t know whether its source was due to software glitches or flaws in networking infrastructure; while observability solutions aim to answer such questions.
Observability vs. Telemetry
Observability involves gathering and analyzing large volumes of data – including metrics, logs and distributed traces – which allows DevOps teams to better understand what’s happening in production, reducing incident response times. By instrumenting apps with observability metrics early enough, potential SLO deltas can be identified before reaching production, helping improve app performance while mitigating customer impact. Furthermore, centralised observability platforms can organize incident information in an organized fashion, filtering out alert noise for faster root cause analysis.
An observability solution provides another useful mechanism for controlling complexity by linking knock-on effects in complex chains, so you can quickly pinpoint the source of problems. Think of it like sending information about different body parts directly to a central brain for instant differentiation of problems; traditional monitoring tools only do this on an aggregated, global level and require engineers manually correlating disparate data sources – leading to many false positives that make finding solutions challenging.
Observability vs. Visibility
The observer effect, or simply put, occurs when observation alters the outcome of what’s being observed; this phenomenon can be found across scientific fields and manifests in paradoxes in which seemingly identical processes appear different when seen from different points of view, defying common sense.
Today’s synoptic observing stations typically use automated visibility sensors and operate fully automatically; however, at certain stations (particularly air traffic services) a trained weather observer still determines representative visibility values on days with changing atmospheric conditions.
Example: On days where there are numerous snow showers north and west of a station, significantly reducing observation coverage (and hence visibility), an observer will record a less-than-ideal representative visibility reading. By contrast, clear days when an entire panoramic view around a station can be clearly seen will result in reporting very good representative visibility values from an observer – making representative visibility values an integral component of quality assurance criteria for bext and PM2.5 measurements.
Observability vs. APM
Observability can supplement monitoring rather than replace it, providing deeper insights into infrastructure that may not be detected by simple monitoring tools alone. Its usefulness in multicloud environments containing microservices, containers and serverless functions cannot be underestimated.
Observability solutions also focus on tracking dependencies among components, which is difficult with monitoring tools that rely on predefined metrics. They’re great for spotting issues caused by changes to production systems; moreover, observability tools allow faster responses when potential issues arise.
Dynatrace provides IT teams with a scalable observability platform to quickly detect and resolve multicloud environments with minimal interruptions to business operations. These platforms feature causal AI engines which sift through large volumes of disparate, high-velocity data from complex IT infrastructure – they analyze this information as one source of truth to create a single source of truth, breaking down information silos that exist within modern IT environments.
Observability vs. Monitoring: Which Is Better?
Answering this question depends entirely upon each organization’s individual requirements. In general, observability tools provide more granular and comprehensive views of IT system health than monitoring tools can. They allow engineers to quickly identify problems within complex software architecture, helping to pinpoint their source.
Observability solutions also provide critical context when it comes to understanding why IT issues arise and how best to resolve them, unlike monitoring tools that use dashboards with predetermined data pulled from IT systems – often limited in scope, showing only performance metrics or usage information your IT team can anticipate.
Observability consists of three main components: logs, metrics and distributed traces. While observability tools do offer some monitoring features, they should not be seen as replacements to your current IT infrastructure – instead they should be utilized as part of an end-to-end solution to monitor and manage complex IT environments, providing teams with an ability to trace issues back from cause to effects and vice versa.
