Our gateway components can act as a data source for Prometheus metrics for time-series-based real-time events and alert monitoring.
When enabled, metrics are available without authentication via HTTPS under:
https://mgt-apache/metrics
Airlock-specific metrics in Prometheus format
The following table lists Airlock-specific metrics that are exposed i.e. for monitoring licensed throughput and common gateway indicator values. Prometheus supports different metric types such as counter, gauge, histogram, and summary.
Read more about metrics types here https://prometheus.io/docs/concepts/metric_types/.
The scope of exposed Prometheus metrics also includes a set of standard low-level general-purpose system metrics.
A metric is published when there has been at least one sample point. The reason is that a sample is required before any output can be generated.
- Note the following:
- Statistically relevant statements always require a sufficient basis such as a certain number of requests, e.g. if
http_requests_duration_seconds_count>1000. - Some metrics provide mapping names as metadata in the form of labels that can be used to assign metrics per mapping.
- Read more here about labels here: https://prometheus.io/docs/concepts/data_model/#metric-names-and-labels

Metric name | Metric type | Unit | Description |
|---|---|---|---|
| Gauge | integer | The number of currently processed requests. |
| Gauge | integer | The duration of request processing in seconds. |
| Counter | integer | The number of requests that are used for This counter is also used as the base for the timing statistics for |
| Histogram | floating point | Timing statistics (percentiles) for request processing durations. The histogram is calculated in quantiles, as described here https://prometheus.io/docs/practices/histograms/#quantiles. |
| Counter | integer | The number of allowed requests. |
| Counter | integer | The number of blocked requests. |
| Counter | integer | The number of rejected requests. |
| Gauge | integer | The number of currently active sessions. |
| Gauge | integer | The number of currently active authenticated sessions. |
| Gauge | floating point | Ratio indicating the workload of the pod/system.
The load values can be interpreted as percentage information between 0–100% load. |
| Gauge | integer | The throughput rate of processed calls in calls/s averaged over one-minute time windows. Only valid calls (requests) forwarded to protected services are counted. Corresponds to the calculated throughput logged-in message with |
