I have seen a couple other posts about this subject, but they don't appear to be answered. I am attempting to use the check_mysql plugin from 1.4.13 (plugin version 2034) with mysql client libraries from mysql 5.1. I don't want to pass the password via -p (whether it be through a $USER$ variable or not), but the plugin doesn't seem to see the password= value in the .my.cnf file present in ~nagios. This is being attempted on Sun SPARC Solaris 10. I have run a truss on the check_mysql command, and it certainly seems to be reading the ~/.my.cnf file that nagios seems to have (I see it open and read /usr/local/nagios/.my.cnf). I have even attempted to put the password in /etc/my.cnf in the [client] section, but no go (not that I'd want to run that way anyway). I am able to use the mysql client directly from the command line, and it reads the .my.cnf file without issue: Examples: (as user nagios) $ mysql -h <hostip> Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 54 Server version: 5.0.45-log MySQL Community Server (GPL) Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> Result: mysql client can connect to the server without issue $ /usr/local/nagios/libexec/check_mysql -H <hostip> Access denied for user 'nagios'@'<monitor server hostname>' (using password: NO) Has anyone run into this and found a way to make it work? Thank You
