Syntax

graphql
queryAnalysis(
      viewName: string,
      queryString: string!, 
      isLive: boolean!,
      languageVersion: LanguageVersionEnum!
   ): queryAnalysis!

For the input, you'll need to provide the name of the view or repository, the query itself, whether the query is live, and the language version (e.g., legacy). For the results, you might want to know if it's suitable for an aggregate alert and any diagnostic information — by way of the drill down.

Example

Raw
graphql
query {
  queryAnalysis(
     queryString: "host:localhost", 
     languageVersion: legacy, 
     isLive: true, 
     viewName:"humio")
  {filterPart, isAggregate, isSinglePhase}
}
Mac OS or Linux (curl)

    -H "Content-Type: application/json" \
    -d @- << EOF
{"query" : "query {
  queryAnalysis(
     queryString: \"host:localhost\", 
     languageVersion: legacy, 
     isLive: true, 
     viewName:\"humio\")

}"
}

Input Parameters

The input datatype is used to indicate the language version (e.g., legacy). Below is a list of choices along with a description of each:

Table: LanguageVersionEnum

ParameterTypeRequiredDefaultStabilityDescription
Some input parameters may be required, as indicated in the Required column. For return values, this indicates that you are assured a value if the field is requested for the results.
Table last updated: Oct 29, 2025
federated1boolean  Long-TermIndicates if Federated version of the LogScale query is used.
filteralertboolean  DeprecatedThis has no effect and is no longer used internally. It will be removed at the earliest in version 1.189.
legacyboolean  Long-TermWhether legacy LogScale query language is used.
xdr1boolean  Long-TermWhether XDR1 is used.
xdrdetects1boolean  Long-TermWhether XDR Detects 1 query language is used.

Returned Values

For the returned datatype, through the drilldowns , you can get any diagnostic information. The table below lists the parameters available and links to sub-parameters:

Table: queryAnalysis

drilldownsdrilldownsyes PreviewThe number associated with the type of page. See drilldowns.
filterPartstringyes PreviewThe query string up to the first aggregator.
isAggregatebooleanyes PreviewWhether the query contains an aggregator.
isSinglePhasebooleanyes PreviewWhether the query doesn't contain a join-like function.
isValidFilterAlertQuery(viewName: string): booleanmultipleyes Preview

Checks if a query is fit for use for a filter alert.

This is deprecated and is no longer used internally. It will be removed in version 1.207. Use instead the analyzeQuery() query with the suggestedAlertType parameter.
