Database monitoring
Redis monitoring that reads real server metrics
An open Redis port doesn't mean your cache is healthy: memory creeps toward maxmemory, the hit rate collapses, a replica falls behind, clients pile up. NoDisrupt connects the way your app does, reads Redis's own INFO metrics on a schedule, and alerts on what they say.
Monitor Redis freeWhat real Redis monitoring watches
"Is the port open" is the least informative signal a database can give you. NoDisrupt watches the things that actually predict an outage:
Connectivity & authentication
Connect with real credentials (AUTH) over TLS: proving auth and the network path, not just an open socket.
Memory & eviction pressure
Track used memory against maxmemory and watch for evictions: the early signal your cache is about to start dropping keys.
Cache hit rate
Alert when the keyspace hit rate drops, before the misses shift load onto your database.
Clients & replication lag
Watch connected and blocked clients and how far a replica is behind its master, so connection leaks and stale replicas surface early.
NoDisrupt monitors Postgres, MySQL and Redis the same way: connect, query, assert, alert.
Redis monitoring FAQ
How do I monitor Redis uptime?
NoDisrupt connects to your Redis instance with real credentials and reads its INFO metrics on a schedule. If Redis responds, connectivity, authentication and the server are all proven: a far stronger signal than a port check.
Can NoDisrupt alert on Redis memory or evictions?
Yes. Every check reads used memory against your maxmemory limit plus the eviction and hit-rate counters, so you are warned when the cache is under pressure before it starts dropping the keys your app depends on.
Does it need an agent installed on Redis?
No. NoDisrupt monitors Redis over a standard connection, the same way your application connects: no agent or module to install, and checks are read-only (INFO), never writing to your data.
What Redis metrics can I alert on?
Memory usage, connected and blocked clients, cache hit rate, evicted keys and replication lag, all read from Redis's own INFO output, with tunable thresholds per monitor.
Catch Redis problems before your users do
Connect, run a real query, and get alerted on latency and results: in under a minute, no agent.
