MongoDB Observability Made Simple
Coroot captures every operation on the wire with eBPF and reads MongoDB's own diagnostics to deliver DBA-grade coverage: query performance, replication, oplog, WiredTiger internals, and backups. All with a quick setup.
Complete MongoDB Visibility
Coroot gives you end-to-end insight into MongoDB performance. eBPF captures every operation on the wire, while the engine's own diagnostics explain exactly why the replica set behaves the way it does.
Full Query Transparency
See every query shape, its latency, and success rate on the wire - no instrumentation, no driver changes, no overhead.
Root-Cause Clarity
Internal metrics pinpoint why performance drops: a lock holder, WiredTiger cache eviction, exhausted concurrency tickets, or a lagging secondary.
Works With Encrypted Traffic
Coroot monitors TLS connections safely by observing traffic with eBPF before encryption and after decryption.
Per-Application Insights
Understand how each service talks to MongoDB - connection counts, open transactions, and query behavior, broken down by client application.
Correlation That Matters
Connect wire-level latency with WiredTiger, replication, and oplog internals for the complete performance story.
Runs Anywhere
Works with any replica set - the Percona Operator, self-managed clusters, or managed MongoDB in the cloud - with a quick setup.
Built-in Health Checks, Zero Configuration
Beyond query performance, Coroot runs the checks a seasoned DBA would - and tells you the root cause, not just that something is wrong.
Availability
Detects an unreachable instance, a replica set with no primary, and members stuck in RECOVERING, ROLLBACK, or DOWN.
Query latency
Flags read, write, and command latency regressions seen on the wire and in the engine, and ranks the likely causes.
Connections
Warns before you exhaust maxIncomingConnections and names the client application driving a connection storm.
Replication lag
Splits lag into blocked vs slow apply and names the cause: a fsyncLock backup, a lock holder, slow disk, or a network partition.
Oplog window
Catches an oplog window too small to survive a restart or maintenance, before a member falls off and needs a full resync.
Saturation
Detects operations queuing and distinguishes exhausted WiredTiger tickets (storage bottleneck) from a lock holder blocking.
WiredTiger cache
Surfaces cache pressure - application-thread eviction and bytes read from disk - when the working set outgrows the cache.
Checkpoints & journal
Tracks checkpoint time, journal write rate, and the amount of journal to replay on crash recovery.
Storage fragmentation
Estimates reclaimable free space per collection so you know when a compact is worth running.
Backups
Catches overdue, failed, or stale backups from the Percona Operator and explains the failure in plain language.
From Database to Application
MongoDB doesn't live in isolation. Coroot shows how query performance impacts the services that depend on it.
Application-Aware Monitoring
See which services issue the slowest queries and how their behavior changes over time.
Deployment Correlation
Instantly connect application releases with shifts in query patterns and database load.
End-to-End Performance
Trace latency from the application layer down to MongoDB to understand the full user impact.
Deep insights into database performance + AI
See how applications talk to MongoDB and why queries slow down. Every connection, every operation, every bottleneck - visible with minimal setup.
AI Root Cause Analysis
When latency or errors spike, Coroot investigates for you: it traces the impact across your services, correlates it with what's happening inside MongoDB, and explains the root cause in plain language. No dashboards to hunt through, no guesswork.
Query Performance Analysis
Coroot collects per-query-shape statistics from the database profiler - executions, total time, and documents and index keys examined versus returned - to surface your most expensive queries and spot collection scans and in-memory sorts.
Query Tracing & Performance
eBPF captures every MongoDB operation on the wire with detailed tracing - latency heatmaps, error rates, and individual operations per client application - without any driver instrumentation, even over TLS.
MongoDB Health & Metrics
Monitor availability, operation latency, connections, replication lag, and the oplog window with real-time charts and built-in health checks. Get instant visibility into replica set health.
Replication & Oplog
Track every secondary's lag alongside the oplog window and apply rate. When a member falls behind, Coroot doesn't just alert - it names the cause right in the alert: a fsyncLock backup, a lock holder, a slow disk, or a broken network path, with the evidence charts attached.
WiredTiger Internals & Saturation
The engine internals that quietly cause latency: concurrency tickets, queued operations, cache eviction, checkpoints, and journal writes. When operations start queuing, Coroot tells you whether you're out of WiredTiger tickets (a storage bottleneck) or blocked on a lock, and points at the backup, long transaction, or index build responsible.
Backups & Recovery
For clusters managed by the Percona Operator, Coroot tracks the backup schedule, point-in-time recovery status, and recent runs, and catches overdue, failed, and stale backups - surfacing the operator's reason when something breaks.
Logs & Automatic Pattern Detection
Coroot collects MongoDB logs out of the box and groups similar messages into patterns automatically, turning a flood of noise into a short, ranked list. Errors and warnings are detected without any manual rules, so a recurring lock, a failed authentication, or a dropped connection stands out at a glance.
Replica-Set & Operator Aware
Coroot understands how your replica set is run. It detects primary, secondary, and arbiter roles automatically, reads backup state from the Percona Operator, and flags risky configurations.
Percona Operator
Backups and point-in-time recovery via Percona Backup for MongoDB, plus cluster status, straight from the custom resources.
Role detection
Primary, secondary, and arbiter roles read from the replica set - no labels or manual configuration required.
Configuration checks
Flags risky topologies (PSA/arbiter, an even number of voters) and a disabled profiler that would hide per-query stats.
Works With All MongoDB Deployments
From Kubernetes replica sets to managed cloud databases - monitor MongoDB anywhere with consistent visibility
Kubernetes
Percona Server for MongoDB and self-managed replica sets, with automatic pod and service discovery
Cloud
Managed and self-managed MongoDB on any cloud, monitored through a read-only cluster-monitor user
Self-Hosted

Why MongoDB Monitoring Is Usually a Pain
Traditional monitoring tools only see one side of the story - either application metrics or database internals, but never how they connect.
How Coroot Solves This
Coroot's dual-layer approach combines wire protocol capture with MongoDB's own diagnostics for complete visibility.
