We are thrilled to announce an enhancement to Instana® with the introduction of the probable root cause capability, now available in public preview starting from release 277. This capability delivers superior insights, allowing quick identification of the source of a system fault—with little to no investigation time.

Probable root cause

Working with IBM Research®, we designed an algorithm that use causal AI and differential observability to analyze data modalities such as traces and topology to identify unhealthy entities after an incident has been triggered. An entity refers to any component within a system that is monitored using Instana’s support for over 300 technologies. By analyzing various data modalities across your infrastructure, applications and services, we are able to identify the likely causes of application outages and point you toward dashboards that will expedite your investigation.

Additionally, we enrich this information by showcasing possible reasons that this entity may have failed, by showing all of the recent events on the identified probable root cause entity. We also present clear explainability as to why our AI identifies an entity as Probable Root Cause. Probable Root Cause also seamlessly directs you toward relevant metrics, traces and logs to speed up further diagnosis of the problem.

Currently, probable root cause automatically runs on all incidents triggered by smart alerts on the following entity types:

• Application Perspectives
• Services
• Endpoints
• Service Levels Objectives on Application Perspectives (currently Public Preview)

Key benefits

• Immediate intelligence: Unlike traditional approaches that require extensive setup and training, probable root cause works out-of-the-box almost immediately. Whether you’re using software as a service or self-hosted deployment, you can start benefiting from enhanced observability without delay.
• Comprehensive insights: Gain unparalleled visibility into your entire stack with Instana’s comprehensive data coverage. From frontend to backend, microservices to databases, probable root cause considers all aspects of your environment to deliver accurate diagnostics.
• Explainable outputs: Instana’s approach is rooted in transparency. We provide clear visibility into the data sources and methodologies used to determine probable root causes, empowering your teams with actionable insights they can trust.
• Secure data protection: Probable Root Cause delivers insights without the data ever leaving Instana, ensuring the sanctity and security of your valuable information.

Probable root cause in action

Here’s a sneak peek about how probable root cause can assist you in the Instana incident dashboard to quickly identify a problem.

In this example, an application smart alert is triggered in case of a sudden increase in number of erroneous calls.

Instana automatically identifies the root cause entity from the smart alert (in this case, an endpoint), provides additional explainability of that fault, as well as any associated events that occur on that entity. This allows the user to efficiently find the cause and prioritize resolving the incident.
