I am using LibreNMS for quite some time now and I am loving it, especially the prompt help I get from its developers when I encounter challenges. We use LibreNMS to poll Enterasys switches and while a lot of issues we have had with them have resolved by the developers, we have a need to be able to poll and graph Internal Storage utilization on the N-series plartform of these devices. As can be seen in the picture below the information is being graphed on the C-series switches.
Upon quick glance of the discovery debug, it looks like this information is being discovered, see github issue #6225;
