LMS 2.6 does not have Availability Reports like there was in 2.2.
You can look at RME - Reports - Report Generator or DFM - Fault History to see there's anything you can use from there. However, nothing will be an exact match to Availability Reports like those in LMs 2.2.
Not in LMS proper, but we will be releasing an add-on to LMS that will encompass features from MRTG, and will bring back some of the old availability capabilities. This is tentatively scheduled for release in the summer of this year.
Does this mean that you have to have MRTG setup seperately and you will install the new LMS add-on and will have to configure it to import information from MRTG to generate Availability report?
This new component will be all self-contained, and will allow for ad hoc polling (like MRTG does) amongst other things.
