WebSocket & Stream Ready

Real-Time
Monitoring

// FOR LIVE APPLICATIONS
Monitor WebSockets, Socket.io, gRPC, and WebRTC streams. Detect latency spikes, connection drops, and handshake failures before your users do.

The Real-Time Challenge

Connection Stability

Persistent connections are fragile. Mobile network switches and timeouts kill sessions instantly.

Message Delivery

Fire-and-forget isn't enough. You need to know if critical events actually reached the client.

State Sync

When connections drop, state gets desynchronized. Detect when clients see stale data.

Global Latency

WebSocket handshake time varies wildly by region. Monitor from where your users are.

Scalability

10k concurrent connections behave differently than 100. Load test your limits.

Protocol Overhead

Monitor the size of your frames and the efficiency of your serialization (JSON vs Protobuf).

Platform Capabilities

WebSocket Handshake Monitoring

Verify connection establishment, protocol switching (101), and SSL/TLS handshake times.

expect: 'status_101'

Pub/Sub Channel Validation

Subscribe to specific channels and verify that messages are received within expected latency windows.

subscribe: 'channel_v1'

Message Content Matching

Parse incoming JSON frames and validate specific fields using JSONPath assertions.

assert: '$.status == ok'

Multi-Path Routing Analysis

500+ concurrent traceroutes from edge networks. Map routing paths to identify why WebSocket handshakes are slow in specific regions.
