tidb -如何解决node_exporter up超时

Question

当使用tidb node_exporter up时，我得到以下输出：

fatal: [tidb@172.17.3.226]: FAILED! => {"changed": false, "elapsed": 309, "msg": "Timeout when waiting for search string 200 OK in tidb@172.17.3.226:9100"}
fatal: [tidb@172.17.3.225]: FAILED! => {"changed": false, "elapsed": 309, "msg": "Timeout when waiting for search string 200 OK in tidb@172.17.3.225:9100"}

我该如何解决这个问题呢？

2. 检查node_exporter进程是否正在运行(ps -ef | grep http://172.17.3.226:9100/metrics)
