Description

This dashboard monitors a Loki + Promtail deployment, focusing on log ingestion health, resource usage, and alerting status. It highlights log flow reliability with metrics like loki_distributor_lines_received_total, loki_distributor_bytes_received_total, and error/warn levels via loki_log_messages_total across level, warn, and error. It also tracks resource consumption and efficiency with % of memory and CPU usage for both Loki and Promtail, and surfaces ingestion failures through loki_distributor_ingester_append_failures_total and dropped entries via promtail_dropped_entries_total to pinpoint bottlenecks in the pipeline.
