Dynatrace Observability

Dynatrace Observability with dtctl

What this skill does

Use this skill to investigate Dynatrace telemetry and security findings with reproducible DQL and dtctl workflows. It is a standalone package: copy the whole folder when deploying it to another project.

The skill favours progressive disclosure: start here, then load only the reference, example, template, or DQL resource needed for the task.

When to use it

Use this skill for:

• production incident response and root cause analysis;
• deployment impact and release health validation;
• production error triage across Davis problems/events, spans, logs, traces, metrics, and user events;
• performance regression checks against baseline behaviour;
• vulnerability and compliance finding review;
• DQL query writing, validation, and troubleshooting;
• Dynatrace terminal workflows with dtctl;
• evidence hand-off into Dynatrace Workflows, dashboards, notebooks, or API automation.

When not to use it

Do not use this skill for:

• generic DevOps advice with no Dynatrace evidence source;
• product marketing, licensing, or procurement questions;
• architecture-only discussions with no operational validation;
• non-Dynatrace observability platforms.

Operating rules

• Evidence first: state what was queried and what the result supports.
• Always set a bounded timeframe before querying high-volume data.
• Optimise DQL in this order: narrow timeframe, filter early, select fields early, transform/parse, aggregate, then sort/limit.
• For service failures, expand span.events and inspect exception records before concluding.
• For Davis analysis, prefer dt.davis.problems and dt.davis.events examples over guessed problem fields.
• For security and compliance posture, use latest-scan or deduplicated current-state patterns, not broad historical counts.
• For Runtime Vulnerability Analytics, state monitoring-mode and deep-monitoring limitations when evidence is incomplete.
• Use entityName(dt.entity.service) for readable service names while filtering by stable entity identifiers where possible.
• Check dtctl context, safety level, and required scopes before running mutating operations.
• If access fails, diagnose context, command capability, token scopes, and safety level before changing the query or conclusion.
• If service, entity, environment, timeframe, or deployment markers are ambiguous, discover candidates or narrow scope before querying high-volume telemetry.
• If correlations are incomplete or contradictory, state evidence gaps and confidence instead of claiming confirmed root cause.
• Prefer --plain, --output json, or --output yaml for automation; do not parse formatted tables.
• Do not include secrets, platform tokens, tenant-specific URLs, or private trace/log payloads in reports.

Reference routing

Load the smallest matching file first:

Bundled resources

• Reusable DQL templates live in resources/dql/.
• Report templates live in resources/templates/.
• Worked examples live in examples/.
• A portable context check helper lives at scripts/validate-dtctl-context.sh.

Validated source areas

This package is aligned to the public Dynatrace documentation areas below. Treat external docs as verification sources, not runtime dependencies.

• Dynatrace Query Language guide, reference, commands, and best practices.
• Logs on Grail examples and DQL timeseries examples.
• Dynatrace Intelligence DQL examples for Davis problems and events.
• Application Security and Runtime Vulnerability Analytics guidance.
• Dynatrace Workflows overview and Dynatrace API reference.

Default workflow

1. Identify the user's intent and select the reference file from the routing table.
2. Establish context: environment, timeframe, service/entity, deployment time, or finding type.
3. Validate access and command capability if dtctl is needed.
4. If access, scope, entity, timeframe, or correlation evidence is incomplete, use references/fallback-guidance.md.
5. Build or adapt DQL from the relevant reference and resources/dql/ template.
6. Run the smallest safe query first, usually with | limit 1 or a narrow timeframe.
7. Correlate at least two relevant sources before stating root cause.
8. Produce an evidence-based report using the relevant template.

Minimal setup

Before deep analysis, establish command and access context.

# Install dtctl (macOS/Linux)
brew install dynatrace-oss/tap/dtctl

# Authenticate (OAuth recommended)
dtctl auth login --context my-env --environment "https://<env>.apps.dynatrace.com"

# Verify config, context, token, connectivity, auth
dtctl doctor

For token-based contexts (for CI/CD or headless runs):

dtctl config set-context my-env \
  --environment "https://<env>.apps.dynatrace.com" \
  --token-ref my-token \
  --safety-level readwrite-mine

dtctl config set-credentials my-token --token "$DT_API_TOKEN"
