Why should you care?

Product leaders justify GPU spend with usage dashboards; compliance wants proof hospital staff override unsafe suggestions.

See it live — copy this example

Paste into an ASP.NET Core 8+ / AgentNest project, then run with dotnet run (set your API keys in user-secrets).

// AgentNest.Analytics/AiUsageRecorder.cs
public sealed class AiUsageRecorder(AgentNestDbContext db)
{
    public async Task RecordAsync(string tenantId, string feature, int tokens, bool thumbsUp, CancellationToken ct)
    {
        db.AiUsageDaily.Add(new AiUsageDaily
        {
            Day = DateOnly.FromDateTime(DateTime.UtcNow), TenantId = tenantId,
            Feature = feature, Tokens = tokens, PositiveFeedback = thumbsUp ? 1 : 0
        });
        await db.SaveChangesAsync(ct);
    }
}

What happened?

• AiUsageRecorder aggregates daily tokens and feedback per feature — CRM draft, hospital triage, ERP explain.
• Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

1. Create AiUsageDaily table partitioned by month.
2. Record usage in middleware after AI responses complete.
3. Build Power BI dataset from SQL or export to Synapse.
4. Add EditDistance metric comparing CRM draft to sent email.
5. Alert when tenant token growth exceeds 200% week over week.

Remember

Aggregate tokens, feature, and feedback per tenant daily. Analytics inform cost allocation and quality improvements. Avoid storing raw prompt text in analytics DB.
