Rule/Cron blocking OpenHAB

So first of all, I am back to business:

I still need to re-incorporate 2-3 rules and run some experiments.
So far my take-aways are:

  • upgrade => clear cache
  • High CPU => top -H -p $(pgrep -x java) to dig in the specific process that goes rogue
  • issues with rules => Move them all to a disabled folder and bring them back in small batches until it breaks again
  • do monitor your cpu/load/temp to get an early alert if a “bad” rule is introduced

On the last point, I am using GIT to manage changes, this is very useful to keep track ot “what has changed recently”. I realize however that I almost never spot newly introduced issues right away unless the changes have a big impact (such as increasing the load significantly as shown on the graph above).
