Native gRPC Protocol Support
gRPC Health Check Monitoring
Most monitoring tools can't speak gRPC. Uptimy uses native protocol support to health check your gRPC services. No HTTP gateway required.

Why gRPC Services Need Specialized Monitoring
gRPC uses HTTP/2 and Protocol Buffers. Standard HTTP monitoring tools can't understand the protocol. You end up adding an HTTP gateway just for health checks, introducing another failure point.
Native Protocol
Speak gRPC directly, no HTTP proxy needed.
Method Validation
Call specific RPCs and validate responses.
mTLS Support
Client certificates for secure service mesh.
Health Protocol
Native support for grpc.health.v1.Health.
03:08 · where it breaks
gRPC Failures HTTP Can't Catch
gRPC services fail in ways that HTTP monitoring completely misses:
- ✗Proto schema mismatch where client and server disagree on message format
- ✗Streaming failures where connection opens but stream immediately errors
- ✗Deadline exceeded because service is too slow for its configured timeout
- ✗Auth failures where metadata/credentials rejected by interceptor

How Uptimy Monitors gRPC
Uptimy connects to your gRPC services using native protocol support:
Health Check Protocol
Automatic support for grpc.health.v1.
Custom RPC Calls
Call any unary method with custom request data.
Server Reflection
Auto-discover methods without uploading protos.
Response Validation
Check response fields match expected values.

Getting Started
Set up gRPC monitoring in the dashboard:
- 1
Create a gRPC Monitor
Select gRPC as your monitor type and enter your service host and port.
- 2
Choose Your Method
Use the standard grpc.health.v1.Health/Check or specify any unary RPC method to call.
- 3
Configure TLS and Auth
Enable TLS for secure connections. Add metadata headers for authentication if needed.
- 4
Set Response Expectations
Define which gRPC status codes indicate success and validate specific response fields.

Frequently Asked Questions
Uptimy uses native gRPC protocol support to connect to your services. We support both secure (TLS) and insecure connections, with optional mTLS for services that require client certificates.
It helps but isn't required. If your service implements the standard gRPC Health Checking Protocol, we use it. Otherwise, you can specify any unary RPC method to call as a health check.
Yes. For streaming RPCs, Uptimy can verify the stream opens successfully and optionally validate the first message received. This catches connection and auth issues.
For services with server reflection enabled, Uptimy discovers methods automatically. Otherwise, you can upload your .proto files or provide them as a URL.
Uptimy monitors for all gRPC status codes. By default, anything other than OK is a failure, but you can configure expected status codes for specific health check scenarios.
