[analyzer] update get_execute_time()

[Tanyy]

we cannot get execute time if head node not a worker.
so, we shall use one of the ceph mon node to get execute time .

nice catch, how about we use the first client? Since cetune is also able to test on non-ceph cluster, so I think client is a must-exist item when extract execute time. What do you think?

cetune还能使用在无ceph节点的场景咯？cool。 我也试过用client节点的时间做为时间戳，但是时间上好像有一点偏差，所以我没选择用client节点。 不过具体的偏差我已经记不清楚了，我再做一些测试看看。或者看看能否有其他的办法。 2017-03-15 13:38 GMT+08:00 Chendi.Xue <[email protected]>:
