Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dt-obs-frontends scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Frontend Observability (RUM)

Monitor web and mobile frontends using Real User Monitoring with DQL. Targets the New RUM Experience only — do not use classic RUM data.

Concepts and data model: https://docs.dynatrace.com/docs/observe/digital-experience/new-rum-experience/concepts

Data Model

Three data sources, each for a different question:

Source Use for Granularity
timeseries dt.frontend.* Trends, dashboards, alerting Aggregated metric
fetch user.events Root cause, individual page views / requests / clicks / errors Per-event
fetch user.sessions Bounce rate, session duration, session-level aggregates Per-session

Rule of thumb: start with metrics for the shape of the problem, drill into events for the why. Use sessions when the question is about user journeys, not individual interactions.

Full event model: https://docs.dynatrace.com/docs/semantic-dictionary/model/rum/user-events

DQL language reference (functions, syntax, operators): https://docs.dynatrace.com/docs/platform/grail/dynatrace-query-language

Key dt.frontend.* metrics (all support dimensions: frontend.name, device.type, geo.country.iso_code, browser.name, os.name, dt.rum.user_type, dt.smartscape.frontend):

  • dt.frontend.web.page.largest_contentful_paint / dt.frontend.web.page.interaction_to_next_paint / dt.frontend.web.page.cumulative_layout_shift / dt.frontend.web.page.first_input_delay — Core Web Vitals
  • dt.frontend.web.navigation.time_to_first_byte / dt.frontend.web.navigation.dom_interactive / dt.frontend.web.navigation.load_event_end — Navigation timing
  • dt.frontend.error.count — Error counts
  • dt.frontend.request.count / dt.frontend.request.duration — Request volume and latency
  • dt.frontend.user_action.count / dt.frontend.user_action.duration — User action volume and duration
  • dt.frontend.session.active.estimated_count / dt.frontend.user.active.estimated_count — Active sessions and users (cardinality metrics; use countDistinct() aggregation)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
