Environment

    2. Take a backup copy for oid2metrics-linux.json from apmia/extensions/hostmonitor-DD/config/ folder. 
    3. Copy the attached "oid2metrics-linux.json" or "oid2metrics-solaris.json into apmia/extensions/hostmonitor-DD/config/ folder. 

NOTE: You need to replace the oid2metrics-linux.json file If customer running APMIA Hostmonitor on linux OS or  oid2metrics-solaris.json file If customer running APMIA Hostmonitor on Solaris OS.
