Metrics in tia® Content Server core
- Stefan Franz
tia®Content Server can be be observed in detail with metrics. Currently there is prometheus exporter support under http://<HOST>:<PORT>/actuator/prometheus
This document describes some of the metrics based on tia® Content Server Core 3.5.0.
On your system the metrics can be partially available due to different system environments.
kgs reserves the right to adapt, add or remove the metrics in newer versions without prior notice
