I had 11 rollup jobs running with no problems for a few months. Just checking on the actual jobs, there were all gone! I do not believe this was malice, but it certainly could have been an accident by someone. Are the rollup jobs themselves stored in an index, and if so, where? We are also using some ILM rules and possibly we got too aggressive on some pattern matching. All the jobs were set up in the GUI via Kibana.
