1.5.1 New Behavior
This plugin allows to reject offers. Possible use-cases are:
- Maintenance. Mark agent as going to maintenance and reject new offers from it.
- Analytics. If task fails, for example, 5 times for 5 minutes, we can assume that it will fail again and reject new offers for it.
- Binding to agents. For example, agents can be marked as included into primary or secondary group. Task can be marked with group name. Plugin can schedule task deployment to primary agents. If all primary agents are busy, task can be scheduled to secondary agents
