Best for: Teams that need comprehensive production incident investigation without replacing their existing observability, infrastructure or incident-response tools.
Sherlocks AI automatically gathers evidence, develops competing hypotheses and tests them against live production data. Its Awareness Graph connects telemetry with service dependencies, infrastructure state, deployments, code changes, operational knowledge and previous incidents.
More than 16 domain-specialized agents can investigate different parts of the environment in parallel, including:
The resulting RCA distinguishes the primary cause from contributing factors and includes confidence, affected services, blast radius, a causal timeline, supporting evidence, ruled-out hypotheses and remediation recommendations.
Investigations can begin from alerts, support tickets or proactive detections, or be started manually in Slack. Engineers can ask follow-up questions and select different investigation depths for initial triage or complex, multi-service failures.
Why it stands out: Sherlocks AI offers the broadest combination of full-stack evidence retrieval, parallel hypothesis testing, explainable RCA, deployment choice and reusable investigation memory in this comparison.
Security and deployment: Its Watson data agent uses read-only, least-privilege access. Options include managed SaaS, an agent inside the customer’s VPC, hybrid deployment, full self-hosting, air-gapped environments and private model endpoints.
Limitations:
Sherlocks AI works best when it has access to enough telemetry, infrastructure, code, and operational context to investigate incidents across the entire environment.
Best for: Engineering organizations investigating production failures that span multiple services, tools and infrastructure layers.
Resolve AI begins investigating when an alert fires. Domain-specialized agents pursue different root-cause hypotheses in parallel, while a separate verifier checks proposed conclusions against production evidence.
It can investigate:
The report separates impact, root cause, causal chain, supporting evidence and remediation. Engineers can inspect individual findings, question the analysis and redirect agents through Resolve’s Workbench. Background deployment monitoring can also compare post-deployment behavior with a rolling baseline and investigate anomalies.
Why it stands out: Resolve is designed for multi-step technical investigation rather than alert summarization. Parallel hypotheses and a distinct verification stage make it well suited to incidents with several plausible causes.
Limitations:
Pricing is custom, usage limits apply, and results depend on consistent integration metadata.
Best for: Organizations that want a PagerDuty incident to progress through evidence gathering, root-cause investigation and governed remediation.
PagerDuty’s SRE Agent combines PagerDuty incident context with evidence retrieved from connected observability, code and knowledge systems. It can use raw alerts, related incidents, recent changes and probable origin as the starting point for deeper investigation.
The agent can:
Connectors cover major observability, cloud, source-control and knowledge systems, including Datadog, New Relic, Dynatrace, Grafana, CloudWatch, Splunk, GitHub and Confluence.
Why it stands out: PagerDuty combines live technical investigation with alert context, service ownership and controlled remediation in one operational workflow.
Limitations:
Deep investigation requires the Advance add-on and depends on configured connectors and available AI Actions.
Best for: Teams that want autonomous technical investigation inside a Slack-native incident-response workflow.
incident.io Investigations begins debugging when an incident is declared. Its AI SRE connects telemetry, code changes, service relationships, deployment history and previous incidents to generate and test a root-cause hypothesis.
Investigations can examine:
Findings include a proposed cause, confidence score and links to supporting evidence. An adversarial agent challenges the initial conclusion, while an investigation timeline records how the analysis developed. Responders can ask follow-up questions or redirect the investigation from Slack.
Why it stands out: incident.io tightly connects technical investigation with service ownership, incident history and the live response channel.
Limitations:
Investigations typically start after incident declaration and depend on connected telemetry, service-catalog quality, and historical data.
Best for: Regulated or security-conscious organizations that need automated investigation inside customer-controlled infrastructure.
Hyground runs as a multi-agent investigation layer inside the customer’s Kubernetes cluster. When an alert fires, it selects relevant systems, queries them in parallel and correlates the evidence into a structured root-cause report.
It can investigate telemetry, Kubernetes events, deployments, configuration changes, cloud accounts, databases, dependencies, code repositories, tickets, runbooks and previous incidents.
Reports include the likely cause, affected services, confidence-ranked findings, supporting evidence and recommended actions. Queries, evidence and reasoning steps are recorded for auditing. Adapters are read-only by default.
Why it stands out: Hyground provides the strongest customer-controlled data boundary in the comparison. Operational data, credentials and investigation history remain within the customer’s infrastructure.
Limitations:
Hyground requires customer-managed Kubernetes and model infrastructure, while engineers remain responsible for production changes.
Best for: Organizations that want dependency-aware causal investigation inside a full-stack observability platform.
Dynatrace Intelligence correlates metrics, logs, traces, topology, transaction flows, anomalies and change events to identify production problems and their probable causes.
An investigation can surface:
Smartscape supplies the real-time dependency graph, while Grail provides the telemetry foundation. Dynatrace Assist adds conversational, multi-step analysis of active problems.
Why it stands out: Dynatrace’s established topology and causal-analysis engine is particularly effective at distinguishing an initiating failure from its downstream symptoms.
Limitations:
Investigation is strongest in Dynatrace-instrumented environments and depends on the broader Grail and Smartscape platform.
Best for: European and regulated teams that want traceable production investigation inside an alerting and on-call platform.
ilert AI SRE investigates incidents using live telemetry, code and recent-change data. An engineer can launch an investigation from an alert, incident or natural-language description.
The agent can inspect:
Each investigation produces a root-cause hypothesis, confidence label, evidence-linked findings, ruled-out causes and a proposed next action. Service topology can come from existing traces or ilert’s eBPF collector.
Why it stands out: ilert delivers concise, evidence-linked findings while supporting European data handling and human control over production changes.
Limitations:
Investigations require manual initiation and depend on connected observability, repository, and CI/CD systems.
Best for: Engineering teams that already use New Relic and want investigation grounded in application telemetry.
New Relic Autopilot can investigate an alert, determine whether it represents a genuine production problem and identify likely causes.
It can:
Operational documentation and previous incident knowledge can supplement live evidence through New Relic AI Knowledge.
Why it stands out: New Relic combines APM-native investigation with direct access to the underlying telemetry, making findings easier to verify than a standalone AI summary.
Limitations:
Investigation is strongest with New Relic telemetry, while some causal features remain in preview and remediation requires approval.
Best for: Enterprise ITOps teams investigating high-volume incidents through correlated alerts, topology and change data.
BigPanda Automated Incident Analysis groups related monitoring signals into incidents and enriches them with service topology, business context, recent changes and historical incident data.
Its Root Cause Changes capability compares active incidents with CI/CD, change-management and audit data. Potentially causal changes are scored using timing, affected resources and alert coverage, helping responders identify the change that preceded downstream failures.
Why it stands out: BigPanda combines enterprise-scale event normalization with change causality, making it useful when the central investigation problem is separating an initiating change from alert noise.
Limitations:
Results depend on normalized monitoring and change data, and a human must confirm the suspected root-cause change.
We assessed whether each product can investigate live production incidents, retrieve technical evidence and produce a supportable root-cause finding.
To qualify, a product must perform technical investigation of live production incidents. Alert correlation, incident coordination, postmortem generation, monitoring and automated remediation alone are insufficient.
The evaluation considered:
Only currently documented capabilities were considered. Roadmap promises, preview functionality and unsupported performance claims were treated cautiously.
| Environment | Prioritize | Platforms to consider |
|---|---|---|
| Single observability stack | Native telemetry access and minimal setup | Dynatrace for Dynatrace environments; New Relic for New Relic environments |
| Multi-cloud or fragmented stack | Tool-neutral retrieval across observability, cloud, code and deployment systems | Sherlocks AI, Resolve AI, PagerDuty |
| Kubernetes-heavy environment | Workload topology, cluster state and deployment awareness | Sherlocks AI, Hyground, Dynatrace |
| Regulated or air-gapped systems | Self-hosting, private models, data boundaries and auditability | Sherlocks AI, Hyground |
| Large microservice estate | Dependency traversal, blast-radius analysis and change correlation | Sherlocks AI, Dynatrace, BigPanda |
| Fast-moving deployment environment | Code, pull-request, CI/CD and configuration analysis | Sherlocks AI, Resolve AI, incident.io |
