I have been trying to configure the Prometheus pump using the Tyk helm chart by setting up the environment variables as instructed in the documentation available at Tyk Pump Environment Variables.
However, I have noticed that the TYK_PMP_PUMPS_PROMETHEUS_META_DISABLEDMETRICS environment variable is not functioning as expected. We intended to disable some of the default metrics using this environment variable.
Welcome to Tyk Community.
TYK_PMP_PUMPS_PROMETHEUS_META_DISABLEDMETRICS is the correct environment variable. You can define it your values.yaml under pump section as extraEnvs.
Actually can you double check using comma-separated values? I can see the "Processing metric:tyk_http_status" message stripped in pump logs when debug mode is enabled.
