Feature Request - Remove swap dashlet if there is no swap
Posted: Wed Jun 08, 2016 12:29 pm
I'm posting this here, but it should apply to any Nagios product that does a dashboard that includes local swap usage.
We've got swap turned off on our test cluster Nagios server. Swapping is bad for some things, but since they all share a physical host, it makes more sense to overcommit memory and let the hypervisor deal with swapping than it does to have the guest machines swap.
So since there is NO swap on our NNA box, the dashlet under Administration | System Dashboard sees zero available swap and displays as 100% usage. While technically correct, better UI would suggest that if there is no swap, then there should be no dashlet.
