I checked with meta and apparently this is the best place to ask!
The company I work at have many environments, and as such, many Nagios/Icinga etc boxes in each environment. We currently have a dashboard, but it was created quickly many moons ago and needs replacing. It currently scrapes the HTML of every box, builds a static HTML file and repeats.
I put together a proof of concept using PHP/MySQL (as I'm good at it) which has a page which is dynamically generated from a MySQL DB, and then there's a background script which fetches data from Nagios/Icinga API's (or resorts to scraping where no API present). This works fine, but I've been itching to learn Node.JS and from what I've read it's good for dashboards - especially as I may want interaction in future.
So, my question is where abouts in this does Node.JS site, and where abouts does it not sit? For example, should I be using Node.JS for the dashboard itself sat on something like MongoDB (never used it, but would like to try NoSQL for once) to show people the current problems etc and then I have a script in the background in PHP/Perl that does the fetching scraping? Or (option 2) does Node do the dashboard AND the fetching of data? Do I have two instances of Node? I'd also like to have a web-based config page (like an admin settings page) rather than flat file settings - again, is this something easily done in the same Node structure or is Node quite single purpose (just display a dashboard, just fetch, just do forms etc)
I could accomplish all of the above with PHP/MySQL fairly easily and quickly, but Node.JS and MongoDB seem really popular nowadays and I feel like I'm missing out.
