dash0.gen_ai.cache_tokens.input is a synthetic metric computed
on-the-fly from the ingested span data.
Each span contributes the value of its
gen_ai.usage.cache_read.input_tokens attribute to the per-bucket
sum.
Deprecated PromQL alias: dash0_gen_ai_cache_tokens_input_total.
Synthetic metrics do not expose attributes by default. Attributes are materialised through PromQL aggregations.

dash0.gen_ai.conversations.info
Identity / metadata mapping for a GenAI conversation.
View the dash0.gen_ai.conversations.info metric in Dash0
| Property | Value |
|---|---|
| Instrument | Gauge |
| Unit | 1 |
| Stability | |
dash0.gen_ai.conversations.info is a synthetic metric computed on-the-fly
from the ingested span data. The value is always 1; the info-style
series exists to carry the conversation's metadata labels
(gen_ai.conversation.id, gen_ai.agent.name, gen_ai.provider.name,
gen_ai.request.model, service.name) so display-layer queries can
join other GenAI metrics against it via PromQL group_left.
Mirrors the pattern established by dash0.slo.info (ENG-7637). Not
intended for alerting or trending — use the per-span counters /
histograms (dash0.gen_ai.chats.*, dash0.gen_ai.tokens.*, etc.) for
that.
Deprecated PromQL alias: dash0_gen_ai_conversations_info.
