If you have set up security on your Nagios®
Remote Plugin Executor (NRPE) agents by limiting the IP address of the servers
permitted to interrogate them, then do not forget to include the new server’s
If you limit Simple Network Management
Protocol (SNMP) communication from a specific IP address, then ensure that your
devices have been updated to allow the new server to receive communication.
Likewise, if you send SNMP traps to the Opsview Monitor master, ensure the traps are
redirected to the new server. To do this, simply edit the nsc.ini file on
Windows or nrpe.cfg on Linux and change the ‘allowed hosts’ directive to
include the IP address of the Opsview Monitor master server.
If you have setup a firewall for web access
to the Opsview Monitor master, this will need to be updated to allow access to the new
Opsview Monitor master’s IP address.
