I had a pre-existing host setup by someone long gone, and am trying to add 2 other new mysql servers to a basic check. I did my best to make the user appear to be setup exactly as I saw the original one was. check_mysql -H hostname -u nagios -p passwd works from the commandline, but then fails from the nagios check. Oddly the original host gives me a access denied from the commandline, but then works from the check nagios sends. Here is the lines from .cfg's pretty basic. commands.cfg # 'check_mysql' command definition define command{ command_name check_mysql command_line $USER1$/check_mysql -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ } services.cfg # Service definition define service{ use generic-service ; Name of service template to use host_name originalserver,newserver service_description MYSQL check_command check_mysql!nagios!NORTREALPASSWD } Newserver on commandline recieves the usual Uptime, threads, etc.. readout, but in nagios returns this error Access denied for user 'nagios'@'qeren.zacks.com' (using password: YES) And oddly it's the opposite for the original server which works in nagios, but returns same error on commandline. Here is what the current permissions are set to which is the same as on the original server as far as I can tell. User:nagios Host:server.domain.com Password:Yes GlobalPrivileges:<TT>U</TT>SAGE<TT> Grant:No</TT> </BODY> </HTML>
