>                 Key: GEODE-2270
>                 URL: https://issues.apache.org/jira/browse/GEODE-2270
>             Project: Geode
>          Issue Type: Improvement
>          Components: docs, gfsh, management
>            Reporter: Wes Williams
>            Priority: Major
>              Labels: ManagementService, MemberMXBean, gfsh, jmx
>
> GIVEN:
> 1) The GfshParser and CommandResult are internal classes.
> 2) CommandResult returns headings, line.separator's and UI concerns along with the answer
> WHEN:
> I pass a gfsh command into a public gfsh API from code
> THEN:
> I get back an XML or JSON representation of the core results without the headings, line.separator's and UI concerns
> EXAMPLE (idea node and not actual implementation):
> WHEN:
>         String gfshResults = gfshPublicAPI("list regions");
>         return gfshResults;
>     String gfshPublicAPI(String gfshCommand) {
>         ParseResult parseResult = gfshParser.parse(gfshCommand);
>         String results = (String) parseResult.getMethod()+"Json"
>           .invoke(parseResult.getInstance(), parseResult.getArguments())
>        return results;
>     }
>     CommandResult gfshInternalAPI(String gfshCommand) {
>         ParseResult parseResult = gfshParser.parse(gfshCommand);
>         CommandResult results = (CommandResult) parseResult.getMethod()
>           .invoke(parseResult.getInstance(), parseResult.getArguments())
>        return results;
>     }
> Another option is to include a new property --output=json into gfsh commands that return the core results without the UI concerns, per Anthony Baker's comment on Fri, 04 Nov, 20:31 at: https://mail-archives.apache.org/mod_mbox/incubator-geode-dev/201611.mbox/browser
