## browser

### browser.bfcache.frame
- Brief: Which frame in the page's frame tree a back/forward cache not-restored reason originated from: the top document or a child frame.
- Type: string
- Apply Scrubbing: manual
- Examples:
  - top
  - child

### browser.bfcache.not_restored_reason_count
- Brief: The number of reported reasons a page was not restored from the back/forward cache on a back/forward navigation. 0 when the browser reported no reasons (e.g. non-Chromium browsers).
- Type: integer
- Apply Scrubbing: manual
- Examples:
  - 2

### browser.bfcache.outcome
- Brief: Whether a back/forward navigation was restored from the browser's back/forward cache (bfcache). 'hit' means the page was restored; 'miss' means it was reloaded.
- Type: string
- Apply Scrubbing: manual
- Examples:
  - hit
  - miss

### browser.bfcache.reason
- Brief: A browser-reported reason a page was not restored from the back/forward cache on a back/forward navigation, taken from the notRestoredReasons API. Reported per reason (a single miss can have several). Currently Chromium-only.
- Type: string
- Apply Scrubbing: manual
- Examples:
  - unload-listener
  - websocket
  - idbversionchangeevent
  - response-cache-control-no-store

### browser.name

- Type: string
- Apply Scrubbing: manual
- Example: Chrome
- Aliases: sentry.browser.name

### browser.navigation.id
- Brief: The identifier of the navigation the measurement belongs to, incremented by the browser for each navigation within a page's lifetime.
- Type: integer
- Apply Scrubbing: manual
- Examples:
  - 1
  - 3
  - 0
- Additional context:
  - Sourced from `PerformanceEntry.navigationId`, defined by the Soft Navigations spec. Despite its origin it is not soft-navigation specific: the field is set on the `PerformanceNavigationTiming` entry of a hard navigation too.
  - The value starts at 1 for the initial page load and increments for each subsequent navigation. It is only unique within a single page lifetime, not globally.
  - A value of 0 is a fallback rather than a real navigation id: web-vitals reports 0 when the browser does not expose `PerformanceEntry.navigationId`, so 0 means the id is unknown.
  - Pairs with `browser.navigation.type`: the type says how the browser arrived at the page, the id says which navigation of that page a measurement belongs to.
  - Not to be confused with the Navigation API's `NavigationHistoryEntry.id`, which is an opaque string identifying a history entry rather than a counter, and is not interchangeable with this value.
  - Also distinct from the `router.navigation.*` attributes, which describe the client-side router's own view of a navigation. Those come from the framework, this one comes from the browser, and both can be set on the same span.

### browser.navigation.type
- Brief: The type of navigation the browser performed to arrive at the page the metrics were measured on.
- Type: string
- Apply Scrubbing: manual
- Examples:
  - navigate
  - reload
  - back-forward
  - back-forward-cache
  - prerender
  - restore
  - soft-navigation
- Additional context:
  - Carries the `navigationType` value reported by the web-vitals library verbatim. web-vitals hyphenates the Navigation Timing `PerformanceNavigationTiming.type` value (`back_forward` becomes `back-forward`) and adds states that API does not cover: `back-forward-cache` for a restore from the back/forward cache, `prerender`, `restore` for a discarded tab being reloaded, and `soft-navigation`.
  - `back-forward-cache` is only set when the page was actually restored from the back/forward cache. A back/forward navigation that missed the cache is a full document load and reports `back-forward`. Use the `browser.bfcache.*` attributes to diagnose misses.
  - `prerender` pages finish painting before activation, so their paint timings are offset by `browser.performance.navigation.activation_start`. Keep them separate when aggregating web vitals.
  - Not to be confused with `router.navigation.type`, which holds the client-side router's own vocabulary (`link`, `goto`, `router.push`). The two are independent and can both be set on the same span.

### browser.paint.type
- Brief: The type of paint timing entry reported by the browser.
- Type: string
- Apply Scrubbing: manual
- Examples:
  - first-paint
  - first-contentful-paint

### browser.performance.navigation.activation_start

- Aliases: sentry.browser.version

### browser.web_vital.cls.report_event
- Brief: The event that caused the SDK to report CLS (pagehide or navigation)
- Type: string
- Apply Scrubbing: manual
- Example: navigation
- Deprecated: yes (The JavaScript SDK stopped setting this in v11. With per-navigation web vitals, web-vitals decides when the CLS value is final, so there is no report event to record. No replacement.)

### browser.web_vital.cls.source.<key>
- Brief: The HTML elements or components responsible for the layout shift. <key> is a numeric index from 1 to N
- Type: string
- Apply Scrubbing: manual
- Example: body > div#app
- Aliases: cls.source.<key>
- Has dynamic suffix: yes

### browser.web_vital.cls.value
- Brief: The value of the recorded Cumulative Layout Shift (CLS) web vital
- Type: double
- Apply Scrubbing: manual

- Type: double
- Apply Scrubbing: manual
- Example: 477.1926
- Aliases: fp

### browser.web_vital.inp.input_delay
- Brief: The time between the user interacting with the page and the browser starting to run the event handlers, for the interaction INP was reported on, in milliseconds
- Type: double
- Apply Scrubbing: manual
- Examples:
  - 120
- Additional context:
  - One of the three INP subparts, which add up to `browser.web_vital.inp.value`: input delay, processing duration and presentation delay. Named after `inputDelay` in the web-vitals attribution build.
  - Measured from the interaction's `PerformanceEventTiming` entry as `processingStart` minus `startTime`.
  - Omitted when INP is reported without an interaction to attribute it to, like `browser.web_vital.inp.target`.

### browser.web_vital.inp.interaction_type
- Brief: The kind of user interaction INP was reported on
- Type: string
- Apply Scrubbing: manual
- Examples:
  - click
  - hover
  - drag
  - press
- Additional context:
  - One of `click`, `hover`, `drag` or `press`, derived from the DOM event name of the Event Timing entry: pointer, mouse and touch events map to `click`, `mouseover` and similar to `hover`, drag and drop events to `drag`, and keyboard and `input` events to `press`. The same value forms the suffix of the span's `ui.interaction.*` op.
  - Not to be confused with the `interactionType` of the web-vitals attribution build, which only distinguishes `pointer` and `keyboard`.
  - Omitted when INP is reported without an interaction to attribute it to, see `browser.web_vital.inp.target`. The op of such a span still falls into `ui.interaction.click` so that it stays within the interaction span family, which makes this attribute, not the op, the way to tell a real click from a value with no interaction.

### browser.web_vital.inp.presentation_delay
- Brief: The time between the event handlers finishing and the browser presenting the next frame, for the interaction INP was reported on, in milliseconds
- Type: double
- Apply Scrubbing: manual
- Examples:
  - 100
- Additional context:
  - One of the three INP subparts, which add up to `browser.web_vital.inp.value`. Named after `presentationDelay` in the web-vitals attribution build.
  - Measured from the interaction's `PerformanceEventTiming` entry as `startTime` plus `duration` minus `processingEnd`.
  - Omitted when INP is reported without an interaction to attribute it to, like `browser.web_vital.inp.target`.

### browser.web_vital.inp.processing_duration
- Brief: The time it took the event handlers to run, for the interaction INP was reported on, in milliseconds
- Type: double
- Apply Scrubbing: manual
- Examples:
  - 140
- Additional context:
  - One of the three INP subparts, which add up to `browser.web_vital.inp.value`. Named after `processingDuration` in the web-vitals attribution build.
  - Measured from the interaction's `PerformanceEventTiming` entry as `processingEnd` minus `processingStart`.
  - Omitted when INP is reported without an interaction to attribute it to, like `browser.web_vital.inp.target`.

### browser.web_vital.inp.target
- Brief: The HTML element selector or component name of the element the user interacted with, for the interaction INP was reported on
- Type: string
- Apply Scrubbing: manual
- Examples:
  - body > div#app > button.submit
  - SubmitButton
- Additional context:
  - Named after `PerformanceEventTiming.target`, the way `browser.web_vital.lcp.element` is named after `LargestContentfulPaint.element`. The value uses the same format as that attribute.
  - Omitted when INP is reported without an interaction to attribute it to. web-vitals reports such a value for a soft navigation whose interactions all stayed below the Event Timing duration threshold, so there is no element to name. The span is still named and still carries `browser.web_vital.inp.value`.

### browser.web_vital.inp.value
- Brief: The value of the recorded Interaction to Next Paint (INP) web vital
- Type: double
- Apply Scrubbing: manual
- Example: 200
- Aliases: inp

### browser.web_vital.lcp.element

- Aliases: lcp.element

### browser.web_vital.lcp.element_render_delay
- Brief: The time between the LCP resource finishing loading and the LCP element being rendered, in milliseconds
- Type: double
- Apply Scrubbing: manual
- Examples:
  - 410
- Additional context:
  - One of the four LCP subparts, which add up to `browser.web_vital.lcp.value`. Named after `elementRenderDelay` in the web-vitals attribution build.
  - Measured as the LCP value minus the LCP resource's `responseEnd`. When the LCP element is text, it covers all time after TTFB.
  - For a prerendered page, timestamps are measured from `activationStart`.

### browser.web_vital.lcp.id

- Type: string
- Apply Scrubbing: manual
- Example: #gero
- Aliases: lcp.id

- Example: 1685
- Aliases: lcp.renderTime

### browser.web_vital.lcp.report_event
- Brief: The event that caused the SDK to report LCP (pagehide or navigation)
- Type: string
- Apply Scrubbing: manual
- Example: pagehide
- Deprecated: yes (The JavaScript SDK stopped setting this in v11. With per-navigation web vitals, web-vitals decides when the LCP value is final, so there is no report event to record. No replacement.)

### browser.web_vital.lcp.resource_load_delay
- Brief: The time between the first byte of the document arriving and the browser starting to load the LCP resource, in milliseconds
- Type: double
- Apply Scrubbing: manual
- Examples:
  - 320.5
- Additional context:
  - One of the four LCP subparts, which add up to `browser.web_vital.lcp.value`: TTFB (`browser.web_vital.ttfb.value`), resource load delay, resource load duration and element render delay. Named after `resourceLoadDelay` in the web-vitals attribution build.
  - Measured as the LCP resource's `requestStart` (or `startTime` when `requestStart` is not exposed) minus TTFB. It is 0 when the LCP element is text, since no resource is loaded.
  - For a prerendered page, timestamps are measured from `activationStart`.

### browser.web_vital.lcp.resource_load_duration
- Brief: The time it took to load the LCP resource, in milliseconds
- Type: double
- Apply Scrubbing: manual
- Examples:
  - 780.2
- Additional context:
  - One of the four LCP subparts, which add up to `browser.web_vital.lcp.value`. Named after `resourceLoadDuration` in the web-vitals attribution build.
  - Measured as the LCP resource's `responseEnd` minus its `requestStart` (or `startTime` when `requestStart` is not exposed). It is 0 when the LCP element is text, since no resource is loaded.

## cache

### cache.hit
- Brief: If the cache was hit during this span.
- Type: boolean
- Apply Scrubbing: manual
- Example: true

### cache.item_age
- Brief: The age of the cache entry in seconds, measured at read time.
- Type: integer
- Apply Scrubbing: manual
- Examples:
  - 5
  - 3600
- Search alias: cache.item_age (second)
- Additional context:
  - Set on reads that return an entry. Absent on a miss, or when the cache does not report a write time.
  - Clamped to 0. On a shared cache, the writer's clock and the reader's clock can drift far enough to make the age negative.
  - Can exceed `cache.ttl`. A cache that discards an expired entry on read still reports the age of that entry, with `cache.hit: false`.

### cache.item_size
- Brief: The size of the requested item in the cache. In bytes.
- Type: integer
- Apply Scrubbing: manual
- Example: 58
- Search alias: cache.item_size (byte)

- Apply Scrubbing: manual
- Example: ["my-cache-key","my-other-cache-key"]

### cache.operation
- Brief: The operation being performed on the cache.

- Apply Scrubbing: manual
- Examples:
  - get
  - put
  - remove

### cache.tags
- Brief: The tags attached to the cache entry. Tags group entries so a cache can invalidate them together.
- Type: string[]
- Apply Scrubbing: auto (Applications pick tag values freely and often build them from record identifiers such as a user id.)
- Examples:
  - ["blog-posts","post-42"]
  - ["products"]
- Additional context:
  - Cache library examples that support tags: Next.js `cacheTag()`, Symfony `ItemInterface::tag()`, Laravel `Cache::tags()`.
  - HTTP caches take tags from a response header. Cloudflare reads `Cache-Tag`, Fastly reads `Surrogate-Key`.
  - Record only the tags the application declared. Leave out implicit tags that the framework adds itself, for example one tag per route.
  - The tags describe the entry, not the operation. Take them from the entry the cache returned or stored.

### cache.ttl
- Brief: The TTL (maximum lifetime) of the cache entry in seconds
- Type: integer
- Apply Scrubbing: manual
- Example: 120
- Additional context:
  - Counted from the write. On a read, the value is the full TTL, not the time that remains.
  - A value of 0 means the entry expires immediately, as with HTTP `max-age=0`. Round a fractional TTL up, so 0.3 seconds becomes 1, not 0.
  - Omit the attribute when the entry never expires, the TTL is unknown, or each read restarts the TTL.

### cache.write
- Brief: If the cache operation resulted in a write to the cache.
- Type: boolean
- Apply Scrubbing: manual
- Example: true

  - For `gen_ai.decide` operations, the array holds one object `{state: ..., questions: {...}}`. `state` is the evaluated state. `questions` holds the questions keyed by name, as the caller passed them. Replace binary data in `state`, including `data:` URLs, with the string `"[Blob substitute]"`. The second example shows this shape.
  - For `gen_ai.extract` operations, the array holds one object `{state?: string, fields: {<name>: <field spec>}, images?: string[], reference_date?: string, options?: {...}}`. This object is the request body as the caller passed it, without `model`. Do not change the values, and leave out the keys that the caller did not set. Do not record the image data. Replace each image with the string `"[Blob substitute]"`. `state` is the text that the model reads. `fields` holds the field specs keyed by field name. Set the model in `gen_ai.request.model`. The third example shows this shape.
