Override Processor Plugin

The override processor plugin allows overriding all modifications that are supported by input plugins and aggregators:

• name_override
• name_prefix
• name_suffix
• tags

All metrics passing through this processor will be modified accordingly. Values of name_override, name_prefix, name_suffix and already present tags with conflicting keys will be overwritten. Absent tags will be created.

Use-case of this plugin encompass ensuring certain tags or naming conventions are adhered to irrespective of input plugin configurations, e.g. by taginclude.

Configuration:

# Add a global tag to all metrics
[[processors.override]]
  name_override = "new name_override"
  name_prefix = "new name_prefix"
  name_suffix = ":new name_suffix"
  [processors.tags.add]
    additional_tag = "tag_value"
    existing_tag = "new tag_value"
