• Deploying snmp_exporter via Ansible Oct 18, 2023 - 3 min read

  A previous post described how to monitor a Synology NAS with SNMP and Prometheus. This post goes over the Ansible role created to deploy the snmp_exporter. I’m rather dissatisfied with the way I’m doing testing with molecule at the moment, so I’m not releasing the full role in a repo at this time. However the important files are layed out.

  It would probably be nicer to build an image with the SNMP exporter and deploy a container, but this Ansible deployment was quick and easy to bang out.

• Monitoring Synology NAS with Prometheus & SNMP Oct 17, 2023 - 6 min read

  My Synology NAS is a very important part of my home network, and until recently it was practically unmonitored. Synology doesn’t make it easy to monitor their NAS devices out of the box. It’s possible to get Prometheus’ node exporter running, but that doesn’t export all of the metrics of interest and is generally a pain to deal with. I also prefer to minimize the number of things running on my NAS. It’s under enough load as is.

• Documenting my current home network Sep 29, 2023 - 3 min read

  My home network setup currently allows me to host multiple useful services in a K3S cluster, as well as access my security footage or any other service remotely over Wireguard. All host level resources are deployed with Ansible for automation. No manual changes allowed.

  That is to say, no manual changes other than OS install. That part still needs to be automated in order to make all hosts truly replaceable.

  Application level automation is largely through helm for services deployed in K3S, and docker-compose managed through Ansible for those special cases.

• Introducing colby.gg Sep 27, 2023 - 2 min read
  The goal of colby.gg is to document the things I find interesting. This includes my HomeLab setup, software practices, and other bits and pieces that may be useful to reference in the future.
