Description

Prom web print metrics like below

fs_namesystem_blocks_total{context="dfs",enabledecpolicies="RS-6-3-1024k",hastate="active",totalsynctimes="10 43 ",hostname="xxx"} 3674006 

getTotalSyncTimes return String, so totalsynctimes will change to tag.

It is difficult to show in grafana. We may get wrong panel, though only one metric is set.
