Support for multi-routing-engine-item in XML #19

Closed Sparc0 closed 2 months ago

Sparc0 commented 5 months ago

When we try to export route engine metrics it works fine on single nodes or chassi based nodes with 2 route engines. But it cant export any metrics from e.g a SRX cluster because the XML output differs a little, and we endout with no metrics at all for the RE's.

MX with 2 RE's

Thanks for the detailed output! Multi-routing-engine-item is now supported in v1.4.0.
