Hi Brian Candler,
Thanks for your response. I tried the below syntax, no errors in the
configuration but metrics are not getting dropped.
remoteWrite:
- url: "http://test.com/push";
write_relabel_configs:
- source_labels: [__name__]
regex: "node_xfs.*"
action: 'drop'
I also tried below syntax but getting error "parsing YAML file
/etc/config/prometheus.yml: yaml: unmarshal errors:\n line 15: field
relabel_configs not found in type config.plain"
remoteWrite:
- url: "http://test.com/push";
relabel_configs:
- action: labeldrop
regex: "node_context_switches_total|node_cooling.*"
Please let me know if i need to try anything different
