• μMon: Stupid simple monitoring
  9 projects | news.ycombinator.com | 24 Sep 2023

  https://collectd.org/ does the gathering (and writing to RRDTool database, if you so desire) part very well. Many plugins, easy to add more (just return one line of text)

  Still need RRD viewere but that's not a huge stack

  And it scales all the way to hundreds of hosts, as on top of network send/receive of stats it supports few other write formats aside from just RRD files.

  why not use https://collectd.org/ which is in C and used by openwrt's luci already along with rrdtool, small in size, low on resource, and has so many plugins already?

  Then you will have same problems but now you can bother manufacturer about it!

  Also unless there is something horribly wrong about how often data is written, that SSD should run for ages.

  We ran (for a test) consumer SSDs in busy ES cluster and they still lasted like 2 years just fine

  The whole setup was a bit of overcomplicated too. RAID10 with 5+1 or 7+1 (yes Linux can do 7 drive RAID10) with hotspare woud've been entirely fine, easier, and most likely faster. You need backups anyway so ZFS doesn't give you much here, just extra CPU usage

  Either way, monitoring wait per drive (easy way is to just plug collectd [1] into your monitoring stack, it is light and can monitor A TON of different metrics)

• CPU Performance of a docker minecraft java server on Raspberry Pi 4
  4 projects | /r/admincraft | 4 Oct 2021

  For metrics storage I'm using a Graphite database and the graph UI itself is Grafana. To get these I'm using the Debian repos they supply with mostly off-the-shelf configs. For collecting metrics from the Pi to send to Graphite I use collectd. It has a lot of off-the-shelf plugins you can use to grab metrics like CPU usage & load average, network in/out, memory stats etc. The Minecraft-specific stuff you can get from configuring collectd plugins as well, like the tick lag graph I use the "tail" plugin to follow and parse the server log.

• Lightweight alternative to Grafana

  For monitoring, personally I use collectd and Collectd Graph Panel (sadly the latter is abandoned, but it still works fine)
