LogQL query builder
Compose LogQL queries visually with Meridian's step-through builder. No hand-writing label matchers or regex filters.
Stream selector
Pick your log stream by namespace, container, or app label. The builder auto-completes valid label names from your cluster's active series.
{namespace="production", app="api-gateway"}Log pipeline
Chain operators visually — line filter, JSON parser, label formatter. Each step previews results against a sample window so you see matches before committing.
|= "error"
| json
| line_format "{{.method}} {{.path}} → {{.status}}"Aggregation
Switch to metric mode with a toggle. Choose rate, count-over-time, or quantile. The builder handles unwrapping and range vector syntax.
rate({app="api-gateway"} |= "5xx" [5m])Tip: Use the Live tail panel to drag-and-drop fields directly into your query pipeline.
