Class QueryRequest

java.lang.Object

io.zipkin.QueryRequest

public final class QueryRequest
extends Object

Invoking this request retrieves traces matching the below filters.

Results should be filtered against endTs, subject to limit and lookback. For example, if endTs is 10:20 today, limit is 10, and lookback is 7 days, traces returned should be those nearest to 10:20 today, not 10:20 a week ago.

Time units of endTs and lookback are milliseconds as opposed to microseconds, the grain of Span.timestamp. Milliseconds is a more familiar and supported granularity for query, index and windowing functions.

Field Detail

serviceName

public final String serviceName

Mandatory Endpoint.serviceName and constrains all other parameters.

spanName

@Nullable
public final String spanName

When present, only include traces with this Span.name

annotations

public final List<String> annotations

Include traces whose Span.annotations include a value in this set.

This is an AND condition against the set, as well against binaryAnnotations

binaryAnnotations

public final Map<String,String> binaryAnnotations

Include traces whose Span.binaryAnnotations include a String whose key and value are an entry in this set.

This is an AND condition against the set, as well against annotations

minDuration

@Nullable
public final Long minDuration

Only return traces whose Span.duration is greater than or equal to minDuration microseconds.

maxDuration

@Nullable
public final Long maxDuration

Only return traces whose Span.duration is less than or equal to maxDuration microseconds. Only valid with minDuration.

endTs

public final long endTs

Only return traces where all Span.timestamp are at or before this time in epoch milliseconds. Defaults to current time.

lookback

public final long lookback

Only return traces where all Span.timestamp are at or after (endTs - lookback) in milliseconds. Defaults to endTs.

limit

public final int limit

Maximum number of traces to return. Defaults to 10
