FAQPage Schema
How do I query and analyze Grafana Loki logs using LogQL?▼

To query Loki logs, you compose LogQL statements to filter log streams and extract metrics. This skill guides agents in building log and metric queries and interacting with the Loki HTTP API to retrieve results.

Can I scope Loki log queries to a specific tenant using X-Scope-OrgID?▼

Yes, tenant scoping is supported by passing the X-Scope-OrgID header. The skill handles tenant-aware API usage by requiring the LOKI_ORG_ID environment variable to configure multi-tenant access for your queries.

Do I need specific environment variables configured to connect to a Loki cluster?▼

Yes, you must define the LOKI_ADDR and LOKI_ORG_ID environment variables. These prerequisites allow the skill to establish connectivity to your Loki endpoint and execute queries safely.

How do I troubleshoot Loki performance and cardinality issues?▼

You can troubleshoot Loki performance by running diagnostic workflows for label discovery and cardinality analysis. The skill provides guided steps to identify high-cardinality labels and optimize query performance across clusters.

What is the best way to discover available labels in a Loki deployment?▼

The best way to discover labels is by querying the Loki API endpoints for label names and values. This skill facilitates label discovery workflows to help you understand the structure of your log data before writing complex LogQL queries.
