Ceph » mgr

Hi,
I'm playing with the crush-compat balancer in 12.2.2, and it sends "foo" commands to the rest api:

2017-12-11 10:37:41.551009 7f224fc20700  1 mgr[balancer] Handling command: '{'prefix': 'balancer reset', 'target': ['mgr', '']}'
2017-12-11 10:37:41.551058 7f224fc20700  1 mgr.server reply handle_command (0) Success

2017-12-11 10:37:47.132941 7f224fc20700  1 mgr[restful] Unknown request 'foo'
2017-12-11 10:37:47.133106 7f224fc20700  1 mgr[restful] Unknown request 'foo'
...

Those seem to come from balancer/module.py, e.g.

result = CommandResult('foo')
            self.send_command(result, 'mon', '', json.dumps({
                'prefix': 'osd crush weight-set reweight-compat',
                'format': 'json',
                'item': 'osd.%d' % osd,
                'weight': [weight],
            }), 'foo')

Cheers, Dan
