Returns true for rows of the given OpenTelemetry signal type - "span", "log" or "metric".
Syntax
isoteltype(signal)Parameters
Prop
Type
Given a dynamic field
This parameter is string-only. In permissive mode — the default — almost every field arrives as a dynamic, so passing one works because Berserk injects asstring: extract-or-null, the value when it really is a string and null otherwise, so the call yields null (a predicate yields false). A property bag or array is therefore not matched, and tostring() is never applied implicitly — use it explicitly to match a bag's JSON text, keys included. Strict mode rejects the dynamic instead of coercing it. See String coercion and the asXXX family.
Returns: bool
Examples
Example 1 — Count spans by name
default
| where isoteltype("span")
| summarize count() by span_name| span_name (dynamic) | count_ (long) |
|---|
Example 2 — Logs for one service
default
| where isoteltype("log") and resource['service.name'] == "ui"
| take 10| $raw (dynamic) | timestamp (datetime) | ingest_time (datetime) | start_time (datetime) | end_time (datetime) |
|---|
