Prometheus then stores these in a time=20 series database and provides easy query access against these data,=20 allowing applications like Grafana simply aggregating and visualizing=20 all them or configuring arbitrary kind of alerts. Summing it up it is very lightweight, simple to integrate but useful=20 only when there's a prometheus runnung for you. You'd not setup a=20 prometheus/grafana stack just because ipfire can run a node_exporter. In this first step, only general OS and IO stats are supported as=20 node_exporter is nativly shipping with. In a later step we can think=20 about adding metrics from log analyzis (number of packets=20 dopped/rejected, number of suspectibles by intrusion detections, ...) or=20 other custom stuff. These would be simply written regularly into a text file (ending with=20 .prom) and placed in some specific local folder on the ipFire file=20 system and would then be picked by node_exporter and simply appended to=20 the http://...:9100/metrics response. Yes, i'd like to maintain this package for the ipfire. I think this=20 would include beside others: - Keep track of and upgrade to new versions - Keep track especially on security alerts - Being reponsive on questions regarding the package - Testing for each supported architecture Kind regards Holger >=20 > I believe that the core devs will expect, if the addon is agreed to be a=20 > valuable additional package, a longer term commitment from yourself to=20 > take on the role of maintainer for the package.
