Notes

  • After replacing the name of a particular field with a new name, you cannot search for the new name.
  • You cannot rename an existing (single) field with multiple names. For example, with an existing field X, you cannot replace X with Y and then replace X with Z in one search string.

    Example of an invalid syntax
    ... | chgname COMPID with site, COMPID with report
  • You cannot rename the default fields HOST, COLLECTOR_NAME, and DATA_PATTERN.

  • You cannot use default field names to specify a target field.
  • You cannot click a renamed field (or tag) to add it to the Fields section (on the Filters panel) or to your search criteria. However, you can use it in a subsequent search command by adding it to your search criteria.
