Cause

This is a known issue (Internal bug DCA-7406 -- Not resolved when the article was created) with healthmond subagents and values were not updated to reflect the change after you delete the core files.

Solution

Restart snmpd service on master and all the segments and issue should get resolved . If not then contact Pivotal support.

Here is a KB article that explains how to restart SNMP services on DCA
