If two agents collect data for the same node using different alias lists (e.g. one using a customized alias list, the other using the default blank list) the names of the servers will toggle between aliases or between aliased and unaliased as data from the different agents comes in.
解决办法
Multiple agents monitoring the same cluster need to use the same secondary property Host Alias list.
