mod/node-core/pkg/services/version/types.go (1)
28-30: LGTM! The interface addition is well-designed.
The new SetGauge method is a good addition to support version telemetry metrics. The method signature is clean and follows metric naming conventions.
mod/execution/pkg/client/client.go (2)
85-85: LGTM! Field initialization is correct.
The initialization of Capabilities and Connected fields is properly done with appropriate default values.
Also applies to: 88-88
137-137: 🧹 Nitpick (assertive)
Consider handling disconnection scenarios.
While setting Connected = true after successful verification is correct, consider handling scenarios where the connection might be lost after initial connection. This could lead to stale connection state.
Suggestions:
- Add connection state handling in error paths
- Consider implementing a connection monitor that periodically verifies the connection status
Let's verify if there are any connection monitoring implementations in the codebase:
mod/execution/pkg/client/engine.go (1)
Line range hint 180-197: Verify telemetry implementation completeness.
While the capability exchange is properly implemented, let's verify that all necessary telemetry points are covered for the Grafana dashboard requirements.
✅ Verification successful
Based on the gathered information, I can now provide the final response:
Telemetry implementation is complete and well-structured
The capability exchange telemetry is properly integrated with the existing metrics system:
- Version metrics are tracked via
SetGaugein the version service - Engine client has comprehensive metrics for payload operations
- Capabilities are properly logged and tracked
- All supported capabilities (V3 methods and version checks) are well-defined in constants
The implementation aligns with the Grafana dashboard requirements by providing both logging and metrics coverage for capability exchange and version tracking.

139-141: 🛠️ Refactor suggestion
Consider improving error handling in the surrounding context.
While the mutex protection is correct, there's an issue in the error handling of the surrounding function. The defer block in verifyChainIDAndConnection assigns the error from Client.Close() but doesn't handle it:
defer func() {
if err != nil {
- err = s.Client.Close()
+ if closeErr := s.Client.Close(); closeErr != nil {
+ s.logger.Error("failed to close client", "err", closeErr)
+ // Optionally wrap both errors
+ err = errors.Wrap(err, closeErr.Error())
+ }
}
}()Likely invalid or redundant comment.

30-30: LGTM!
The addition of the go-ethereum beacon engine import is appropriate for using the ClientVersionV1 type.
Line range hint 184-193: Verify client version compatibility
The implementation looks good and aligns with the PR objectives for telemetry. However, we should verify compatibility with different execution clients.
✅ Verification successful
Based on the search results, I can generate the final response as we have sufficient information about client version compatibility. The code shows that:
- The implementation includes proper client version checks and compatibility handling
- There's a dedicated
GetClientVersionV1method that follows the Engine API spec - The code has proper error handling and logging for version compatibility
- The codebase supports all major Ethereum execution clients as documented in README.md
- The
Code: "GE"parameter is a required field as noted in the comments, and some clients enforce this
Client version compatibility implementation is correct
The current implementation properly handles client version compatibility:
- It uses the standard
engine_getClientVersionV1method - Includes the required
Code: "GE"parameter that some clients enforce - Has proper error handling and logging
- Supports all major Ethereum execution clients (Geth, Erigon, Reth, Besu, Nethermind, EthereumJS)

165-168: LGTM! Type parameters align with telemetry requirements.
The addition of *ExecutionPayload and *PayloadAttributes type parameters to ReportingService correctly supports the PR's objective of adding telemetry for beacon and eth version tracking.
165-168: Document the type parameters
The previous review comment about documenting type parameters is still valid. Consider adding documentation to explain how these parameters relate to the telemetry functionality:
+// ReportingService is a type alias for the version reporting service.
+// Type parameters:
+// - ExecutionPayload: Used for tracking execution client payload versions
+// - PayloadAttributes: Used for tracking payload attribute versions
ReportingService = version.ReportingService[
*ExecutionPayload,
*PayloadAttributes,
]mod/node-core/pkg/services/version/version.go (5)
43-46: Excellent Use of Generics in ReportingService
The introduction of generic type parameters ExecutionPayloadT and PayloadAttributesT with appropriate constraints in the ReportingService struct enhances flexibility and type safety. This allows the service to handle various execution payloads and attributes seamlessly.
88-142: Efficient Connection Handling and Periodic Reporting
The Start method effectively waits for the execution client to connect before proceeding with telemetry reporting. By using a goroutine and checking the connection status, it ensures that telemetry data is only reported when the client is ready. The periodic fetching of the Ethereum version at the specified reportingInterval keeps the telemetry information up-to-date, accommodating scenarios where the execution client may change versions independently.
146-165: Enhanced Console Output with Informative Details
The printToConsole method provides a user-friendly console output that includes the beacon node version, Ethereum client details, and system information. This improves the user's visibility into the running versions and can aid in troubleshooting or verifying the environment.
167-193: Robust Retrieval of Ethereum Client Version with Proper Error Handling
The GetEthVersion method checks for the execution client's capability to provide version information and handles scenarios where this capability is absent. By initializing ethVersion with default "unknown" values and updating it only when the information is successfully retrieved, it ensures that the application remains stable even if the execution client lacks certain functionalities.
Line range hint 195-221: Comprehensive Telemetry Logging and Metric Reporting
The logTelemetry method effectively logs the versions and system information to both the console and the telemetry sink. By including labels for the beacon node version and Ethereum client details, it enhances the granularity and usefulness of the telemetry data collected. This can significantly aid in monitoring, analytics, and the creation of dashboards for visualizing node versions across the network.

🛠️ Refactor suggestion
Enhance version telemetry during capabilities exchange.
Since this PR aims to create a Grafana dashboard for version tracking, consider capturing the execution client version information during capabilities exchange.
// Capture and log the capabilities that the execution client has.
for _, capability := range result {
s.logger.Info("Exchanged capability", "capability", capability)
s.Capabilities[capability] = struct{}{}
+ // Extract and set version information if the capability contains version details
+ if version := extractVersionFromCapability(capability); version != "" {
+ s.metrics.SetGauge("execution_client_version", 1, map[string]string{
+ "version": version,
+ "client": s.Client.Name(),
+ })
+ }
}This enhancement will help populate the Grafana dashboard with version information from connected execution clients.

Enhance field documentation and consider access patterns
The documentation and organization of the fields could be improved:
- The Capabilities documentation should explain why it's public and its intended usage patterns

✅ Verification successful
Public Capabilities field is justified, but documentation can be improved
The public visibility of the Capabilities field is warranted as it's used by external services (version service) to check for supported features. The current usage patterns show:
- External read access in version service for feature detection
- Internal management during capability exchange
Suggested documentation improvement:
-// Capabilities is a map of capabilities that the execution client has.
+// Capabilities is a map of capabilities that the execution client has.
+// This field is exposed publicly to allow external services to check
+// for supported features (e.g., version service checks GetClientVersionV1).🏁 Scripts executed

95-107:
Prevent potential goroutine leak by adding a connection timeout
The goroutine in the Start method waits indefinitely for the client to connect. If the client never connects, this could lead to a goroutine leak and resource exhaustion. Consider implementing a timeout mechanism to handle scenarios where the client fails to connect within a reasonable timeframe.
Apply this diff to add a timeout to the connection wait loop:
connectedTicker := time.NewTicker(time.Second)
+connectionTimeout := time.After(30 * time.Second) // Set a timeout duration
go func() {
// wait until the client is connected
connected := false
for !connected {
select {
case <-connectedTicker.C:
connected = rs.client.IsConnected()
+ case <-connectionTimeout:
+ connectedTicker.Stop()
+ rs.logger.Error("Timeout while waiting for client connection")
+ return
case <-ctx.Done():
connectedTicker.Stop()
return
}
}
Context
This PR adds telemetry for logging the beacon node and the connected eth execution client. With this telemetry data we should be able to produce a grafana dashboad of a running network to see which nodes are running which version. I also updated the console reporting to include the eth client version once its connected. The implementation should support the case where the execution clients gets restarted using a newer version.
The metric looks like this:
Test plan
I started a local beacon node, and after it connects to the eth execution client it outputs the eth version to console:
Tested when using Geth
Tested when using Reth
