I have written a series of articles recently on tool to graph timeseries data. Nagios is the most complex; it is comprised of Nagios core (which is OSS) and Nagios XI (which is not OSS, but is the server), and as many plugins as you need 1. Nagios is owned by Nagios Enterprises; and real use of Nagios normally requires a licence 2, pricing from 2019 3. AFAIK Nagios is always on-prem install, as it needs access to too many internal systems for it to be external. Nagios setup is not a simple task, mostly as its scope is bigger than just time-series graphs.

With respect to timeseries charts, Nagios:

  • Runs on mobile 4 5.
  • Can monitor blogs and CMS 6, but doesn't includes these features.
  • By itself, Nagios has no user authentication; but as it normally runs inside a webserver, the webserver can supply this 7 8.
  • Is mostly a unicode supporting tool (over the last decade there have been many small bugs where support wasn't complete). The documentation has been ported to quite a few languages 9.
  • [NOTE] The best graphing option I can see is installing highcharts 10 11. Highcharts gives you many options 12 13.
  • Has poor native GIS, but plugins are available 14 15.
  • [NOTE] Has a range of maths features 16 however Nagios is designed with minimal features and lots of plugins.
  • Some data prediction is possible 17
  • [NOTE] The main website only has a short range of supported databases 18 19, and nothing for bigdata. There is a section for PG in the plugin shop 20; and if you look many big data options, e.g. 21 22 etc
  • This item has come up much shorter, I will need to extend
