I acquired this Paul Waechter microscope a while back. It was in quite a rough shape, most of the brass plated parts had the brass rust off or corroded. I decided to only fix the severely broken parts and keep as much of it original, as possible. I’m generally not a fan of making old things look new and shiny again, old things have the right to look old and used.
So I got this Thales MEZ a while back which was in a super bad shape: In particular after a general outside clean I redid the paint on the front-panel, as the majority was rusted off: However, I did not clean it on the inside at the time and just put it into my shelf to sit there. Now I decided to finish what I started and repair the rest of it.

For a couple of machines it was fine, but as soon as it got more collectd caused a constant load on my disks due to all the RRD files that need to be written. In order to reduce this I decided to use rrdcached, which comes with the default RRD install on FreeBSD. It can be configured for collectd on FreeBSD as follows:
