There're 800 hosts been monitored, Is it possible to bulk modify host alias? or other plugin can do this?

Host1 alias abc01
Host2 alias abc02
......

change to

Host1 alias abc01_HQ
Host2 alias abc02_HQ
......

This doesn't appear to be an option in the bulk modification tool, but you could script something to modify the alias lines found in the configs(/usr/local/nagios/etc/hosts/) and then use the import tool(Configure > Core Config Manager > Tools > Import Config Files) to import the modified configs.
