Compared to bamboo.agent_status(), which provides a response. But I need active agents, while agent_status() provides some list of inactive old agents hence trying to use activity() instead to see not building agents.

Also tried using rest api, but it doesn't show if an agent busy/not..

curl -H "Authorization: Bearer XXX" https://bamboo.example.com/rest/api/latest/agent/123456/status
{"online": "true"}%
