feat: add comprehensive per-service statistics tracking

Browse source 
Add full support for tracking and analyzing data by service in multi-tenant deployments.

## Features Added

- **Service Statistics Tracking**: Track nouns, verbs, and metadata counts per service
- **Service Activity Monitoring**: Track first/last activity timestamps and operation counts
- **New API Methods**:
  - `listServices()`: List all services with their statistics and status
  - `getServiceStatistics(service)`: Get detailed stats for a specific service
  - Enhanced `getStatistics()` with service filtering and breakdown

- **Service Filtering**: Filter search results and queries by service
- **Storage Enhancements**: BaseStorageAdapter tracks service activity with timestamps
- **Type Definitions**: Added ServiceStatistics interface and extended StatisticsData

## Implementation Details

- Services automatically tracked via defaultService config or per-operation override
- Service status detection (active/inactive/read-only) based on activity
- Memory-efficient tracking at statistics level, not per noun/verb
- Backward compatible - existing data tracked under 'default' service

## Documentation

- Comprehensive guide in docs/guides/per-service-statistics.md
- Examples for multi-tenant apps, health monitoring, and auditing
- API reference and migration guide included

## Testing

- Full test suite in tests/service-statistics.test.ts
- Coverage of all new methods and filtering capabilities

This enables better observability, debugging, and management of multi-service Brainy deployments, addressing the need to track individual service performance when multiple services share storage.

# Per-Service Statistics and Tracking Guide
Brainy provides comprehensive per-service statistics tracking, allowing you to monitor and analyze data from different services sharing the same storage backend.

- [Configuration](#configuration)
- [Service Tracking](#service-tracking)
- [Statistics Methods](#statistics-methods)
- [Service Filtering](#service-filtering)
- [Use Cases](#use-cases)
- [API Reference](#api-reference)
## Overview
When multiple services (e.g., `bluesky-package`, `github-package`, `scout-search`) share the same Brainy storage, per-service statistics help you:
- **Track individual service performance** - Monitor how many nouns/verbs each service has stored
- **Debug service-specific issues** - Isolate problems to specific services
- **Monitor service health** - Track last activity timestamps and error counts
- **Audit data sources** - Know which service created which data
- **Analyze usage patterns** - Understand how different services use the database
## Configuration
### Setting a Default Service
When creating a Brainy instance, specify a default service name:
```typescript
const brainy = new BrainyData({
defaultService: 'github-package',
storage: {
// Storage configuration
}
})
```
### Specifying Service Per Operation
You can override the default service for individual operations:
```typescript
// Add data with explicit service
await brainy.add(
{ content: 'repository data' },
{ noun: 'Repository' },
{ service: 'github-service' }
)
// Create relationship with service tracking
await brainy.relate(
sourceId,
targetId,
{ verb: 'stars' },
{ service: 'github-service' }
)
```
## Service Tracking
### Automatic Tracking
Brainy automatically tracks for each service:
- Total nouns created
- Total verbs created
- Total metadata entries
- First activity timestamp
- Last activity timestamp
- Operation counts (adds, updates, deletes)
- Error counts
### Service Activity States
Services can have three states:
- **`active`** - Had activity within the last hour
- **`inactive`** - No recent activity
- **`read-only`** - Only performs read operations (no writes)
## Statistics Methods
### List All Services
Get a list of all services that have written data:
```typescript
const services = await brainy.listServices()
// Returns:
[
{
name: 'bluesky-package',
totalNouns: 12450,
totalVerbs: 34820,
totalMetadata: 12450,
firstActivity: '2024-01-01T00:00:00Z',
lastActivity: '2024-01-06T16:30:00Z',
status: 'active',
operations: {
adds: 12450,
updates: 230,
deletes: 0
}
},
{
name: 'github-package',
totalNouns: 45230,
totalVerbs: 89420,
totalMetadata: 45230,
lastActivity: '2024-01-06T16:25:00Z',
status: 'active'
}
]
```
### Get Service-Specific Statistics
Get detailed statistics for a single service:
```typescript
const stats = await brainy.getServiceStatistics('github-package')
// Returns:
{
name: 'github-package',
totalNouns: 45230,
totalVerbs: 89420,
totalMetadata: 45230,
firstActivity: '2024-01-01T00:00:00Z',
lastActivity: '2024-01-06T16:25:00Z',
status: 'active',
operations: {
adds: 45230,
updates: 1250,
deletes: 50
},
errorCount: 5
}
```
### Filter Global Statistics by Service
Filter the global statistics to specific services:
```typescript
// Single service
const stats = await brainy.getStatistics({
service: 'bluesky-package'
})
// Multiple services
const stats = await brainy.getStatistics({
service: ['bluesky-package', 'github-package']
})
// Returns statistics with serviceBreakdown:
{
nounCount: 57680,
verbCount: 124240,
metadataCount: 57680,
serviceBreakdown: {
'bluesky-package': {
nounCount: 12450,
verbCount: 34820,
metadataCount: 12450
},
'github-package': {
nounCount: 45230,
verbCount: 89420,
metadataCount: 45230
}
}
}
```
## Service Filtering
### Filter Search Results
Filter search results to only include data from specific services:
```typescript
const results = await brainy.search('javascript', 10, {
service: 'github-package'
})
```
### Filter Noun Queries
Get nouns only from specific services:
```typescript
const nouns = await brainy.getNouns({
filter: {
service: 'bluesky-package',
nounType: 'Post'
}
})
```
### Filter Verb Queries
Get verbs only from specific services:
```typescript
const verbs = await brainy.getVerbs({
filter: {
service: 'social-service',
verbType: 'follows'
}
})
```
## Use Cases
### Multi-Tenant Applications
When multiple applications share the same Brainy storage:
```typescript
// Application A
const brainyA = new BrainyData({
defaultService: 'app-a',
storage: sharedStorage
})
// Application B
const brainyB = new BrainyData({
defaultService: 'app-b',
storage: sharedStorage
})
// Monitor usage per application
const services = await brainyA.listServices()
for (const service of services) {
console.log(`${service.name}: ${service.totalNouns} nouns`)
}
```
### Service Health Monitoring
Monitor the health and activity of different services:
```typescript
async function monitorServiceHealth() {
const services = await brainy.listServices()
for (const service of services) {
if (service.status === 'inactive') {
console.warn(`Service ${service.name} is inactive`)
}
if (service.errorCount && service.errorCount > 100) {
console.error(`Service ${service.name} has high error count: ${service.errorCount}`)
}
// Check for stale services
if (service.lastActivity) {
const lastActivity = new Date(service.lastActivity)
const daysSinceActivity = (Date.now() - lastActivity.getTime()) / (1000 * 60 * 60 * 24)
if (daysSinceActivity > 7) {
console.warn(`Service ${service.name} hasn't been active for ${daysSinceActivity} days`)
}
}
}
}
```
### Data Source Auditing
Track which service created specific data:
```typescript
// Add data with service tracking
const docId = await brainy.add(
{
content: 'Important document',
timestamp: new Date().toISOString()
},
{
noun: 'Document',
createdBy: { augmentation: 'audit-service' }
},
{ service: 'audit-service' }
)
// Later, verify the source
const stats = await brainy.getServiceStatistics('audit-service')
console.log(`Audit service created ${stats.totalNouns} documents`)
```
### Performance Analysis
Analyze ingestion rates and patterns per service:
```typescript
async function analyzePerformance() {
const services = await brainy.listServices()
for (const service of services) {
if (!service.firstActivity || !service.lastActivity) continue
const start = new Date(service.firstActivity)
const end = new Date(service.lastActivity)
const durationHours = (end.getTime() - start.getTime()) / (1000 * 60 * 60)
const nounsPerHour = service.totalNouns / durationHours
const verbsPerHour = service.totalVerbs / durationHours
console.log(`${service.name} performance:`)
console.log(` Nouns/hour: ${nounsPerHour.toFixed(2)}`)
console.log(` Verbs/hour: ${verbsPerHour.toFixed(2)}`)
}
}
```
## API Reference
### Configuration Options
```typescript
interface BrainyDataConfig {
/**
* Default service name for all operations
*/
defaultService?: string
// Other configuration options...
}
```
### Operation Options
```typescript
interface OperationOptions {
/**
* Override the default service for this operation
*/
service?: string
// Other operation options...
}
```
### Service Statistics Type
```typescript
interface ServiceStatistics {
/**
* Service name
*/
name: string
/**
* Total number of nouns created by this service
*/
totalNouns: number
/**
* Total number of verbs created by this service
*/
totalVerbs: number
/**
* Total number of metadata entries
*/
totalMetadata: number
/**
* First activity timestamp
*/
firstActivity?: string
/**
* Last activity timestamp
*/
lastActivity?: string
/**
* Error count for this service
*/
errorCount?: number
/**
* Operation breakdown
*/
operations?: {
adds: number
updates: number
deletes: number
}
/**
* Service status
*/
status?: 'active' | 'inactive' | 'read-only'
}
```
## Best Practices
1. **Always specify a defaultService** when creating Brainy instances to ensure proper tracking
2. **Use consistent service names** across your application
3. **Monitor service health regularly** using `listServices()`
4. **Use service filtering** when debugging service-specific issues
5. **Track error counts** to identify problematic services
6. **Archive inactive services** periodically to maintain performance
## Migration Guide
If you have existing data without service tracking:
```typescript
// Set a default service for untracked data
const stats = await brainy.getStatistics()
// All existing data will be under the 'default' service
console.log(stats.serviceBreakdown['default'])
// Going forward, specify explicit services
const brainy = new BrainyData({
defaultService: 'my-app-v2',
// ...
})
```
## Limitations
- Service tracking is done at the statistics level, not embedded in each noun/verb
- Service filtering in search operations depends on metadata structure
- Historical service activity may not be available for data created before enabling tracking
- Service names should be kept reasonably short for performance
## Examples
### Complete Example: Multi-Service Dashboard
```typescript
import { BrainyData } from '@soulcraft/brainy'
async function createServiceDashboard() {
const brainy = new BrainyData({
defaultService: 'dashboard',
storage: {
// Your storage configuration
}
})
await brainy.init()
// Get all services
const services = await brainy.listServices()
// Sort by most active
services.sort((a, b) => {
const aTime = a.lastActivity ? new Date(a.lastActivity).getTime() : 0
const bTime = b.lastActivity ? new Date(b.lastActivity).getTime() : 0
return bTime - aTime
})
// Display dashboard
console.log('=== Service Dashboard ===')
console.log(`Total Services: ${services.length}`)
console.log('')
for (const service of services) {
console.log(`Service: ${service.name}`)
console.log(` Status: ${service.status}`)
console.log(` Nouns: ${service.totalNouns}`)
console.log(` Verbs: ${service.totalVerbs}`)
if (service.lastActivity) {
const lastActivity = new Date(service.lastActivity)
console.log(` Last Active: ${lastActivity.toLocaleString()}`)
}
if (service.operations) {
console.log(` Operations:`)
console.log(` Adds: ${service.operations.adds}`)
console.log(` Updates: ${service.operations.updates}`)
console.log(` Deletes: ${service.operations.deletes}`)
}
console.log('')
}
// Get aggregate statistics
const totalStats = await brainy.getStatistics()
console.log('=== Total Statistics ===')
console.log(`Total Nouns: ${totalStats.nounCount}`)
console.log(`Total Verbs: ${totalStats.verbCount}`)
console.log(`Total Metadata: ${totalStats.metadataCount}`)
}
createServiceDashboard().catch(console.error)
```
This comprehensive per-service statistics feature enables better observability, debugging, and management of multi-service Brainy deployments.
