Monitoring Metrics

​
Endpoint Metrics

On each endpoint’s dashboard:
MetricDescription
RequestsTotal requests over time
Success RatePercentage of successful requests
Avg LatencyAverage response time
Token UsageTotal tokens consumed
CostTotal estimated cost

​
Charts

  • Request Volume — Requests over time
  • Latency Distribution — P50, P95, P99 latencies
  • Error Rate — Failures over time
  • Model Usage — Breakdown by model

​
Setting Up Alerts

Custom alerting is available on Pro and Enterprise plans.
Configure alerts for:
  • Error rate exceeds threshold
  • Latency exceeds threshold
  • Daily cost exceeds budget
  • Unusual traffic patterns

​
Debugging Common Issues

​
High Latency

  1. Check the model — Some models are slower
  2. Check input size — Large inputs take longer
  3. Check time of day — Provider congestion varies
  4. Check max tokens — Higher limits may cause longer generation

​
High Error Rate

  1. Check validation errors — Are inputs malformed?
  2. Check provider status — Is OpenAI/Anthropic down?
  3. Check rate limits — Are you exceeding limits?
  4. Check prompt — Is it producing valid JSON?

​
Unexpected Outputs

  1. View rendered prompt — Is the template rendering correctly?
  2. Check temperature — Too high may cause variations
  3. Review recent changes — Did the prompt change?
  4. Replay request — Reproduce the issue
