OutWit.Common.Logging.Loki

Grafana Loki backend for OutWit.Common.Logging.Query.

Contents

  • LokiHttpClient — typed HttpClient over /loki/api/v1/*. Handles basic auth and the X-Scope-OrgID multi-tenancy header.
  • LokiOptions — BaseUrl, TenantId, basic-auth creds, DefaultLabels (always applied as stream selectors), MaxResultLimit, MaxRange.
  • LokiLogQueryProvider : ILogQueryProvider — translates LogQuery to LogQL via LogQL/LogQlBuilder, parses the streams / matrix responses back to LogEntry and LogStatistics.
  • Response/* — JSON DTOs.

LogQL mapping

Neutral query LogQL output
DefaultLabels = { service_name = "WitIdentity" } {service_name="WitIdentity"}
LogFilter on stream label (service.name, level, …) folded into the stream selector
LogFilter on JSON attribute ... \| json \| attr op "value"
FullTextSearch = "passkey" ... \|~ "passkey"
From..To start=<unix-ns>&end=<unix-ns>
PageSize &limit=N (capped to LokiOptions.MaxResultLimit)
SortOrder &direction=forward|backward

For GetStatisticsAsync, the provider issues sum by (level) (count_over_time({...} | json [range])) and aggregates per-level counts (Trace/Debug → DebugCount; Error/Critical/Fatal → ErrorCount).

Known limitations

Method Behavior
FindOffsetAsync Loki has no row-offset concept — returns -1. UI callers should narrow the time window instead.
GetStorageInfoAsync Loki's HTTP API doesn't expose ingestion volume. Returns an all-null LogStorageInfo. Operators wanting quota data should integrate with the Loki admin metrics endpoint or Prometheus directly.
GetDistinctValuesAsync Backed by /loki/api/v1/label/{name}/values — works for stream labels (cheap) but not for arbitrary JSON-body attributes.

Usage

services.AddSingleton(new LokiOptions
{
    BaseUrl = "http://loki:3100",
    DefaultLabels = new Dictionary<string, string> { ["service_name"] = "WitIdentity" }
});
services.AddHttpClient<LokiHttpClient>();
services.AddSingleton<ILogQueryProvider, LokiLogQueryProvider>();
