npx skills add redis/agent-skills --skill redis-observability
Redis observability guidance — which metrics to monitor (memory, connections, hit ratio, ops/sec, rejected connections), which built-in commands to reach for during incident triage (SLOWLOG, INFO, MEMORY DOCTOR, CLIENT LIST, FT.PROFILE), and when to use the Redis Insight GUI. Use when setting up monitoring or alerts for a Redis instance, diagnosing a performance regression, profiling a slow FT.SEARCH query, or wiring Redis metrics into Prometheus, Datadog, or similar.

What to watch, what to run, and what to alert on. Covers the metrics every Redis deployment should monitor and the built-in commands for ad-hoc diagnosis.
FT.SEARCH or pipeline.These come from INFO and should be exported to your monitoring system.
| Metric | What it tells you | Alert when |
|---|---|---|
used_memory | Current memory usage | > 80% of maxmemory |
connected_clients | Open connections | Sudden spikes or drops |
blocked_clients | Clients waiting on blocking ops | > 0 sustained |
instantaneous_ops_per_sec | Current throughput | Significant drops |
keyspace_hits / keyspace_misses | Cache hit ratio | Hit ratio < 80% |
rejected_connections | Hit maxclients cap | > 0 |
rdb_last_save_time | Last persistence snapshot | Too old vs. RPO |
Reach for these when something looks off.
| Topic | Command |
|---|---|
| Slow commands | SLOWLOG GET 10 / SLOWLOG LEN / SLOWLOG RESET |
| Server snapshot | INFO all (or INFO memory / INFO stats / INFO clients / INFO replication) |
| Memory diagnostics | MEMORY DOCTOR / MEMORY STATS / MEMORY USAGE <key> |
| Connections | CLIENT LIST / CLIENT INFO |
| RQE / Search | FT.INFO <idx> / FT.PROFILE <idx> SEARCH QUERY "..." |
The two most useful for incident triage:
SLOWLOG GET to find queries that exceeded the slowlog-log-slower-than threshold (10ms by default). The output shows the exact command and duration in microseconds.MEMORY DOCTOR for memory pressure — it returns a one-paragraph summary of what's unusual about memory usage right now.For interactive use (running queries, browsing keys, profiling indexes), Redis Insight is the official GUI. It surfaces the same SLOWLOG / INFO / FT.PROFILE data visually and includes Redis Copilot for natural-language queries. Useful during development and incident response; not a replacement for exporting metrics to your monitoring system.
