I've seen this in some XML parser scripts, but can't find documentation for it. A few questions if I may?

1. What does it do?

2. Is it available for the json parser too?

3. Is there any more cool stuff hidden away? :)

4. Could you please update the documentation?


1. By default, if a monitoring command does not parse any metrics nor dynamic variables -- because of either missing or malformed data -- it will fail. This allows one to declare that the command will not fail in such a scenario.

2. Yep.

3. Perhaps :) (and thus the hunt for hidden easter eggs begins)

4. Just did (in both the XML and JSON operators' documentation pages).
