# PromQL Prometheus UI: <http://127.0.0.1:9090> (loopback only). ## API - Instant: `curl '<http://127.0.0.1:9090/api/v1/query?query=up>'` - Range: `curl '<http://127.0.0.1:9090/api/v1/query_range?query=up&start=...&end=...&step=15s>'` ## Metric cheat sheet - `up`, `scrape_duration_seconds`, `scrape_samples_scraped` - `vault_*` (Vault `/v1/sys/metrics`), `consul_*` (Consul `/v1/agent/metrics`) - `pg_*` (postgres-exporter), `redis_*` (redis-exporter) - `kafka_connect_*` / `debezium_*` (JMX exporter for Kafka Connect) - Prometheus self: `prometheus_tsdb_*`, `prometheus_engine_*` ## Common patterns - Jobs with a down target: `count(up == 0)` - Error rate: `sum(rate(<metric>_total[5m])) by (job)` - Latency p95: `histogram_quantile(0.95, sum(rate(<metric>_bucket[5m])) by (le))`
