1. 下载nagios监控插件 # wget http://www.percona.com/redir/downloads/percona-monitoring-plugins/LATEST/percona-monitoring-plugins-1.0.3.tar.gz 2. 监控命令定义 define command{ command_name check-mysql-processlist command_line $USER1$/pmp-check-mysql-processlist -l $USER9$ -p $USER10$ -H $HOSTADDRESS$ -P $ARG1$ -w $ARG2$ -c $ARG3$ } define command{ command_name check-mysql-status-pct command_line $USER1$/pmp-check-mysql-status -l $USER9$ -p $USER10$ -H $HOSTADDRESS$ -P $ARG1$ -x $ARG2$ -o $ARG3$ -y $ARG4$ -T pct -w $ARG5$ } define command{ command_name check-mysql-status-4-single-var command_line $USER1$/pmp-check-mysql-status -l $USER9$ -p $USER10$ -H $HOSTADDRESS$ -P $ARG1$ -x $ARG2$ -w $ARG3$ -c $ARG4$ } define command{ command_name check-mysql-status-incr command_line $USER1$/pmp-check-mysql-status -l $USER9$ -p $USER10$ -H $HOSTADDRESS$ -P $ARG1$ -x $ARG2$ -I $ARG3$ -w $ARG4$ -c $ARG5$ } define command{ command_name check-mysql-status-compare command_line $USER1$/pmp-check-mysql-status -l $USER9$ -p $USER10$ -H $HOSTADDRESS$ -P $ARG1$ -x $ARG2$ -o $ARG3$ -y $ARG4$ -C '$ARG5$' -w $ARG6$ -c $ARG7$ } 说明：$USER9$是监控用户名，$USER10$密码。 在resource.cfg文件中定义。 3. 数据库授权 mysql> grant super,porcess, REPLICATION CLIENT ON *.* TO 'nagiosuser'@'10.1.1.1' IDENTIFIED BY 'nagiospassword'; 4. 添加主机监控项 define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-processlist-3306 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-processlist!3306!16!32 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-processlist-3308 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-processlist!3308!16!32 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-status-pct-connection-3306 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-pct!3306!Threads_connected!/!max_connections!80 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-status-pct-connection-3308 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-pct!3308!Threads_connected!/!max_connections!80 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-Threads_running-3306 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-4-single-var!3306!Threads_running!20!40 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-Threads_running-3308 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-4-single-var!3308!Threads_running!20!40 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-Created_tmp_disk_tables-3306 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-incr!3306!Created_tmp_disk_tables!10!10!30 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-Created_tmp_disk_tables-3308 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-incr!3308!Created_tmp_disk_tables!10!10!30 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-Created_tmp_files-3306 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-incr!3306!Created_tmp_files!10!10!30 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-Created_tmp_files-3308 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-incr!3308!Created_tmp_files!10!10!30 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-Created_tmp_tables-3306 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-incr!3306!Created_tmp_tables!10!10!30 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-Created_tmp_tables-3308 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-incr!3308!Created_tmp_tables!10!10!30 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-Table_locks_waited-3306 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-incr!3306!Table_locks_waited!10!10!30 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-Table_locks_waited-3308 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-incr!3308!Table_locks_waited!10!10!30 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-key_hit_rate-3306 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-compare!3306!Key_reads!/!Uptime!<!20!10 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-key_hit_rate-3308 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-compare!3306!Key_reads!/!Uptime!<!20!10 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-full_table_scan-3306 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-compare!3306!Handler_read_rnd_next!/!Handler_read_rnd!>!20!30 } define service{ use mysql host_name xxx.xxx.xxx.xxx service_description check-mysql-full_table_scan-3308 normal_check_interval 2 contact_groups admin_4 check_command check-mysql-status-compare!3306!Handler_read_rnd_next!/!Handler_read_rnd!>!20!30 } 5. 展示 提供一个快速添加监控项脚本。 使用方法 perl mysql_jk.pl 监控文件目录 服务器列表 组名 如： perl mysql_jk.pl /usr/local/nagios/etc/conf/ttlsa.com serverlist.txt admin_4 serverlist.txt格式如下： 1.1.242.50,10.1.242.50,3306,3308 [codesyntax lang="perl"] #!/usr/bin/perl use strict;
