Run a Loki range query through Grafana datasource proxy.

Args: query: LogQL expression, e.g. {app="myservice"} |= "error". limit: Maximum number of log lines to return (1–5000, default 100). direction: "backward" (newest first, default) or "forward". start: Start of the time range. RFC 3339 or Unix nanosecond string. end: End of the time range. RFC 3339 or Unix nanosecond string.

Returns: JSON payload from Loki with streams and log entries.

Run a Loki instant query through Grafana datasource proxy.

Args: query: LogQL expression. limit: Maximum number of log lines to return (1–5000, default 100). at: Evaluation timestamp. RFC 3339 or Unix nanosecond string. Defaults to now when omitted.

Returns: JSON payload from Loki with matching log entries.

List available Loki label names from the configured datasource.

Args: start: Optional start of the time range for filtering. end: Optional end of the time range for filtering.

Returns: JSON array of label name strings.

List available values for a given Loki label.

Args: label: Label name, e.g. "app" or "namespace". start: Optional start of the time range for filtering. end: Optional end of the time range for filtering.

Returns: JSON array of label value strings.

Run an instant PromQL query against Thanos.

Args: query: PromQL expression, e.g. rate(http_requests_total[5m]). time: Optional evaluation timestamp. Accepts RFC 3339 strings (2024-01-01T00:00:00Z) or Unix timestamps as strings. Defaults to now when omitted.

Returns: JSON payload from Thanos containing resultType and result.

Run a PromQL range query against Thanos.

Args: query: PromQL expression. start: Start of the time range. RFC 3339 or Unix timestamp string. end: End of the time range. RFC 3339 or Unix timestamp string. step: Query resolution step width. Duration string (60s, 5m) or float seconds.

Returns: JSON payload with resultType: "matrix" and the time-series data.

List all metric label names available in Thanos.

Args: start: Optional start of the time range for label filtering. end: Optional end of the time range for label filtering.

Returns: JSON array of label name strings.

List time-series matching a PromQL selector.

Args: match: One or more comma-separated series selectors, e.g. {job="prometheus"} or up,{job="api"}. Each comma-separated value is sent as a separate match[] parameter. start: Optional start timestamp for the look-up window. end: Optional end timestamp for the look-up window.

Returns: JSON array of label-set objects describing each matching series.
