Health test result for NODE_MANAGER_WEB_METRIC_COLLECTION has become bad

Hi,

 

Sometimes i will get the alert from Cloudera management UI, only one of my active name node can not get self monitoring metric. I checked and pasted logs of cloudera-scm-agent log file. 

 

I think this issue should have no impact to my production, but do you guys have any reolutions to aviod this only?
