One thing which we'd really love to see more of is graphing and reporting. Currently, the graphing is very closely tied into hosts and services, and I'm not aware of any way that we can bring in data from the same service across multiple hosts, on one graph. For example, it'd be neat if we could have the ram usage for ten servers running the same software put onto one graph.
The graphing also seems to be very focused on 'performance data', which is understandable, as thats what its designed for. However, we've started using it to provide capacity data (e.g. disk space and database size), so it'd be very cool if we could get some other graph types, maybe Pie charts? The 'Metrics' section on XI looks *extremely* promising, and I'd be interested to see how this develops. We'd love to be able to get our own plugins and checks feeding data into there.
Configuring custom graphs is also quite complicated at the moment from what I can see. A wizard for configuring custom graphs would be brilliant.
As for reporting, the standard reports are great, but don't really have enough customisability. I'd like to get to a stage where we do all our capacity and customer reporting out of Nagios, and have it fully automated. I can't really say specifically what we want, but I think if we had the ability to create custom graphs / charts, and include them all on one page (with some custom text next to it), our requirements would be met. Even if this was to become a sperate (paid-for) add on for Nagios, we'd probably go for it as it would save a lot of time.
Once again, thanks for the amazing support so far.
Thanks,
Gavin
