Can you include the Juniper JunOS poller as a default for all Juniper devices in Solarwinds NPM and a default reports to show all versiuon of JunOS like the Cisco IOS reports.
There is a guide to manually add this on your website, link below, but I think it should be part of the default polling. The only difference from the standard poller is the ability to display the JunOS version in the Software version field, as such this then allows a report rto be created to shows the version of JunOS.
