| 2015-01-19 12:02:46 josnyder hi rob_, t0m | |
| 2015-01-19 12:03:19 josnyder i indeed overlooked that we should be using a sensu agent socket to send messages | |
| 2015-01-19 12:05:46 josnyder rob_: I'm specifically thinking of a use case where a job gets scheduled over a chronos cluster and sends results to sensu | |
| 2015-01-19 12:06:39 josnyder so any of 100s of machines could run the job, and then want to report the same client/check pair to the sensu aggregator | |
| 2015-01-19 12:06:52 rob_ josnyder: hey :) | |
| 2015-01-19 12:07:29 rob_ josnyder: sounds like you could just send it to a sensu-agent somewhere then, right? | |
| 2015-01-19 12:07:38 josnyder yeah, each of the nodes will have a sensu agent | |
| 2015-01-19 12:07:40 rob_ could even have a few sensu agents running and load balance them :) | |
| 2015-01-19 12:07:44 josnyder yep | |
| 2015-01-19 12:07:58 josnyder but there's no guarantee that the job will be scheduled or run correctly |
