Dtctl

Dynatrace Control with dtctl

Operate dtctl, the kubectl-style CLI for Dynatrace. Pattern: dtctl <verb> <resource> [flags].

Initialization

Run once to establish context, permissions, and the command catalog:

dtctl commands                          # compact overview: verbs, resources, subcommands (TOON default)# dtctl commands --brief                 # + mutating/access/scopes + flag types# dtctl commands --full                  # exhaustive catalog: descriptions, flag defaults, global flagsdtctl config current-context            # active contextdtctl config describe-context $(dtctl config current-context) --plain  # env URL + safety leveldtctl auth status --plain               # token type (OAuth vs API/platform) + safety leveldtctl inventory                         # what data exists HERE: fetchable objects, buckets, entity census, capabilities

Safety levels: readonly, readwrite-mine, readwrite-all, dangerously-unrestricted.

dtctl commands answers "what can I run?"; dtctl inventory answers "what is there to query?" — run it before exploratory DQL. It partitions catalog objects into fetchable vs query-only (never fetch metrics or fetch smartscape.*), and reports capabilities as present, absent (with the evidence checked — cite it instead of re-probing), or unknown (no verdict; not evidence of absence). Org-specific capability definitions: --definitions file.yaml.

Don't use dtctl auth whoami to test connectivity — it needs an OAuth token with app-engine:apps:run and returns a spurious 403 for plain API or read-scoped tokens even when reads work. Confirm with a real get/query.

DQL (required reading)

Before writing, modifying, or running any DQL (dtctl query, dtctl wait query, query files), consult references/DQL-reference.md and follow it over any assumption or memory.

dtctl query "fetch logs | filter status='ERROR' | limit 100" -o json --plaindtctl query -f query.dql --set host=h-123 --set timerange=2h -o json --plain   # Go-template varsdtctl wait query "fetch spans | filter test_id='test-123'" --for=count=1 --timeout 5mdtctl query "timeseries avg(dt.host.cpu.usage)" -o chart --plain

Billable fetch (logs, events, bizevents, spans) bills by bytes scanned and dashboard tiles re-bill on every refresh — read "Scan Cost" in references/DQL-reference.md before emitting DQL, and treat a PARTIAL or sampled result as incomplete.

Resources & verbs

Resources and aliases are discoverable via dtctl commands (run at init). They include: analyzer, anomaly-detector, app, aws/azure/gcp connection & monitoring, bucket, copilot-skill, dashboard, document, edgeconnect, environment, extension, extension-config, function, group, intent, license, license-settings, lookup, notebook, notification, sdk-version, segment, settings, settings-schema, slo, slo-template, trash, user, workflow, workflow-execution. Use IDs, not names — names may be ambiguous and fail.

Davis analyzers: before running one, dtctl describe analyzer <id> shows its required/optional inputs and result schema (add --doc for full docs, -o json for the raw schemas); dtctl verify analyzer <id> -f in.json validates an input without executing (exit 0 valid / 1 invalid).

Output for agents

--agent/-A is auto-detected in AI environments (implies --plain; opt out with --no-agent). It wraps output in {ok, result, context} (errors: {ok:false, error:{code,message}}, where context carries total, has_more, suggestions).

-o toon          # token-efficient structured output — prefer for agents-o json|yaml|csv # other machine formats-o jsonl|parquet # streaming / columnar export for large results (pipe to a file, query with DuckDB)-o chart|sparkline|barchart   # time series-o table|wide    # human-readable (table is the default)--jq '.[].id'    # filter structured output (json|yaml|toon; other formats auto-promote to json)

Prefer --agent plus -o toon and --jq to cut tokens. Agent-mode query trims metadata to cost/sampling fields by default; -M=all for the full block.

Query results: branch on result.kind

In agent mode dtctl query defaults to --spill=auto: large results spill to a local file and return a summary instead of dumping rows into context. Never assume result is an array — branch on result.kind:

Treat an unknown kind as opaque and fall back to context (decided, total, warnings, suggestions). Sampled results put stats in a sample_stats block (basis: "sample") — not population truth.

dtctl query "fetch logs | limit 1000000" --agent     # auto-spills if largedtctl query "fetch logs" --spill=never               # force every row inlinedtctl query "fetch logs" --spill-to ./out.jsonl      # explicit path: jsonl|json|csv|parquetdtctl query "fetch logs" --spill=auto --spill-threshold 100KB

Inline results are bounded too. String values are clipped to 500 chars by default and end in …(+N chars) (--max-field-chars 0 gives full values; add | fields <col> to fetch only that column). --max-output-tokens N / --max-output-bytes SIZE returns only the rows that fit. When context.truncated is true the result is incomplete: truncated_fields lists the clipped fields, and returned < total means rows were dropped. In that case run context.next (a dtctl inspect command) to continue at next_offset without re-querying.

Inspect a spilled file (no Grail re-query)

dtctl inspect <file> reads the rows the summary left out — bounded, streaming, agent-context-friendly — so you never re-run the Grail scan. Pick exactly one primitive per call:

dtctl inspect <path> --head 20                          # first N rows (the manifest never carried rows)dtctl inspect <path> --tail 10                          # last N rowsdtctl inspect <path> --page --offset 1000 --limit 50    # a window deep in the result (file order)dtctl inspect <path> --head 20 --fields timestamp,content  # project columns (composable)dtctl inspect <path> --schema                           # re-derive columns + types + null countsdtctl inspect <path> --stats                            # re-derive the per-column profile (or --stats=col,col)dtctl inspect --list                                    # lost the path? enumerate spilled files in this context

It is not a query engine — no filter/SQL/GROUP BY. For aggregates, push the work back into DQL (… | summarize …); for complex local analysis, hand the file to your preferred local analytics tooling. An oversized inspect window re-spills to a new file rather than flooding context, and refuses files from another context/tenant.

Log pattern analysis (token-frugal)

For free-text log triage, don't dump raw content — extract the taxonomy server-side, then drill:

1. dtctl exec analyzer dt.statistics.clustering.LogPatternExtractor --input '{"logQuery":"<DQL>","numberOfExamples":2}' → DPL templates + match counts. logQuery is a plain DQL string (not an object) yielding timestamp+content. Projects well with --jq to {patternExpression, numberOfMatches}.
2. Lift a patternExpression verbatim into parse content, "..." (rename captures f_1→meaningful), then summarize … by:{field} to extract/count at row scale. Unmatched lines yield null captures.
3. Need raw rows? Drill with fetch … --agent and let it spill (above), then read them with dtctl inspect <path> --head/--page (above).

Apply & templates

dtctl apply is idempotent: POST when new, PUT when the file has an id. YAML/DQL files support Go templates filled via --set:

title: "{{.environment}} Deployment"cron: "{{.schedule | default "0 0 * * *"}}"

dtctl apply -f file.yaml --set environment=prod --set schedule="0 6 * * *"

Dashboards

Create/update: dtctl apply -f dashboard.yaml. Export for reference: dtctl get dashboard <id> -o yaml --plain. Full schema + visualizationSettings: references/resources/dashboards.md [blocked].

name: "Dashboard Name"type: dashboardcontent:  settings:    defaultTimeframe: { enabled: true, value: { from: now()-2h, to: now() } }  layouts:    "1": { x: 0, "y": 0, w: 12, h: 6 }    # 24-col grid (full=24); quote "y" (YAML bool)  tiles:    "1":      title: "Tile"      type: data                          # data | markdown      query: "fetch logs | limit 10"      visualization: lineChart            # singleValue|lineChart|areaChart|barChart|pieChart|table|honeycomb|scatterplot      davis: { enabled: false, davisVisualization: { isAvailable: true } }

Gotchas: set davis.enabled: false on data tiles; makeTimeseries for log/span series, timeseries for metrics; id present → update, absent → create; the version warning on create is benign.

Permissions & safety

• Verify before mutating: dtctl auth can-i <verb> <resource>. Scopes: TOKEN_SCOPES.md.
• Destructive ops may be blocked by safety level — switch with dtctl config use-context <name>, or raise the level when creating the context.
• Prefer get/describe first; --mine scopes to resources you own; --plain for all machine consumption.

Credentials & teardown

Credentials are dtctl's business: read and remove them only through dtctl.

dtctl config delete-context <name> --delete-credentials  # context + its credentialdtctl config delete-credentials <token-ref>              # credential alone (shared, or context already gone)dtctl auth status --plain                                # presence check — never prints the token

Never invoke OS keychain tooling — security (macOS), secret-tool (Linux), cmdkey (Windows) — for any purpose, cleanup included. Their delete verbs miss most of what a credential occupies; their read verbs print secrets, and security dump-keychain covers every keychain on the machine, not just dtctl's. Never verify a deletion by reading the secret back — a teardown step that prints a token has leaked exactly what it was told to destroy.
