**Title:** Implement health monitoring across all tiers
|
||
|
|
|
||
|
|
**Status:** done
|
||
|
|
|
||
|
|
**Dependencies:** 33 ✓, 34 ✓
|
||
|
|
|
||
|
|
**Priority:** medium
|
||
|
|
|
||
|
|
**Description:** Extend health monitoring to track connectivity and status across mcplocal, mcpd, and individual MCP server instances.
|
||
|
|
|
||
|
|
**Details:**
|
||
|
|
|
||
|
|
1. Update mcplocal health monitor in `src/mcplocal/src/health.ts`:
|
||
|
|
```typescript
|
||
|
|
export class TieredHealthMonitor {
|
||
|
|
async checkHealth(): Promise<TieredHealthStatus> {
|
||
|
|
return {
|
||
|
|
mcplocal: {
|
||
|
|
status: 'healthy',
|
||
|
|
llmProvider: await this.checkLlmProvider(),
|
||
|
|
uptime: process.uptime()
|
||
|
|
},
|
||
|
|
mcpd: await this.checkMcpdHealth(),
|
||
|
|
instances: await this.checkInstancesHealth()
|
||
|
|
};
|
||
|
|
}
|
||
|
|
|
||
|
|
private async checkMcpdHealth(): Promise<McpdHealth> {
|
||
|
|
try {
|
||
|
|
const health = await this.mcpdClient.get('/api/v1/health');
|
||
|
|
return { status: 'connected', ...health };
|
||
|
|
} catch {
|
||
|
|
return { status: 'disconnected' };
|
||
|
|
}
|
||
|
|
}
|
||
|
|
|
||
|
|
private async checkInstancesHealth(): Promise<InstanceHealth[]> {
|
||
|
|
const instances = await this.mcpdClient.get('/api/v1/instances');
|
||
|
|
return instances.map(i => ({
|
||
|
|
name: i.name,
|
||
|
|
status: i.status,
|
||
|
|
lastHealthCheck: i.lastHealthCheck
|
||
|
|
}));
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
2. Add health endpoint to mcplocal HTTP server: `GET /health`
|
||
|
|
3. Update mcpctl status command to display tiered health
|
||
|
|
4. Add degraded state detection:
|
||
|
|
- LLM provider unavailable but mcpd reachable
|
||
|
|
- Some instances down but others healthy
|
||
|
|
5. Add health event notifications for state transitions
|
||
|
|
6. Add configurable health check intervals
|
||
|
|
|
||
|
|
**Test Strategy:**
|
||
|
|
|
||
|
|
1. Unit test: Health check correctly identifies all states
|
||
|
|
2. Unit test: Degraded state is detected correctly
|
||
|
|
3. Integration test: Full health check across all tiers
|
||
|
|
4. Test health endpoint returns correct format
|
||
|
|
5. Test mcpctl status displays health correctly
|
||
|
|
6. Test state transition events are emitted
