Hey Jeff, thanks for trying the Prometheus integration capability. Which NetScaler firmware version are you trying ? It should be 13.1-42.47 or later. Secondly, I want to ensure you are trying out the latest documentation - https://docs.netscaler.com/en-us/citrix-adc/current-release/ns-ag-appflow-intro-wrapper-con/prometheus-integration.html. From the error logs it seems, there is some issue either in the schema.json file. Check if there is no comment on the top that starts with /* in this file. Regards, Komal
