Настройка мониторинга лог-файлов в Nagios

Январь 16th, 2016

Evgeniy Kamenev

1.Установка плагина для проверки лог-файлов (как на Nagios-сервере, так и на клиентском сервере)

# wget https://labs.consol.de/assets/downloads/nagios/check_logfiles-3.7.4.tar.gztar xvzf check_logfiles-3.7.4.tar.gz

1	# wget https://labs.consol.de/assets/downloads/nagios/check_logfiles-3.7.4.tar.gztar xvzf check_logfiles-3.7.4.tar.gz

# cd check_logfiles-3.7.4/

1	# cd check_logfiles-3.7.4/

# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios --with-perl=/usr/bin/perl

1	# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios --with-perl=/usr/bin/perl

config.status: creating t/Makefile
                       --with-perl: /usr/bin/perl
                       --with-gzip: /usr/bin/gzip
              --with-seekfiles-dir: /var/tmp/check_logfiles
              --with-protocols-dir: /tmp
               --with-trusted-path: /bin:/sbin:/usr/bin:/usr/sbin
                --with-nagios-user: nagios
               --with-nagios-group: nagios

config.status: creating t/Makefile

--with-perl: /usr/bin/perl

--with-gzip: /usr/bin/gzip

--with-seekfiles-dir: /var/tmp/check_logfiles

--with-protocols-dir: /tmp

--with-trusted-path: /bin:/sbin:/usr/bin:/usr/sbin

--with-nagios-user: nagios

--with-nagios-group: nagios

# make

# make

# make install

1	# make install

# ls -al /usr/lib64/nagios/plugins/ | grep check_logfiles

1	# ls -al /usr/lib64/nagios/plugins/ \| grep check_logfiles

-rwxr-xr-x 1 root root   203754 Jan 14 23:12 check_logfiles

1	-rwxr-xr-x 1 root root 203754 Jan 14 23:12 check_logfiles

2.Тестирование плагинов с командной строки Просмотр справки

# /usr/lib64/nagios/plugins/check_logfiles --help | less

1	# /usr/lib64/nagios/plugins/check_logfiles --help \| less

В самом простом случае достаточно вызвать команду с необходимыми параметрами Например

# /usr/lib64/nagios/plugins/check_logfiles -t 15 --tag=system --logfile=/var/log/messages --criticalpattern='OOM killed process'

1	# /usr/lib64/nagios/plugins/check_logfiles -t 15 --tag=system --logfile=/var/log/messages --criticalpattern='OOM killed process'

OK - no errors or warnings|system_lines=0 system_warnings=0 system_criticals=0 system_unknowns=0

1	OK - no errors or warnings\|system_lines=0 system_warnings=0 system_criticals=0 system_unknowns=0

Принцип работы плагина подразумевает, что проверка будет происходить первый раз полностью всего […]

Настройка мониторинга MySQL в Nagios средствами Percona Monitoring Plugins

Январь 14th, 2016

Evgeniy Kamenev

1.Установка Percona Nagios Monitoring Plugins на Nagios-сервере (будет использоваться удаленное подключение к MySQL для снятия статистики) (в случае использования NRPE эти плагины необходимо установить на каждом клиенте, который будет мониториться)

# yum install http://www.percona.com/downloads/percona-release/redhat/0.1-3/percona-release-0.1-3.noarch.rpm

1	# yum install http://www.percona.com/downloads/percona-release/redhat/0.1-3/percona-release-0.1-3.noarch.rpm

# yum install percona-nagios-plugins

1	# yum install percona-nagios-plugins

Plugins are installed to /usr/lib64/nagios/plugins

1	Plugins are installed to /usr/lib64/nagios/plugins

2.Создание файла с учетными данными пользователя для удаленного доступа

# mkdir /etc/nagios/

1	# mkdir /etc/nagios/

# nano /etc/nagios/mysql.cnf

1	# nano /etc/nagios/mysql.cnf

[client]
user = nagiosuser
password = nagiospassword

[client]

user = nagiosuser

password = nagiospassword

# chown root:nagios /etc/nagios/mysql.cnf

1	# chown root:nagios /etc/nagios/mysql.cnf

# chmod 640 /etc/nagios/mysql.cnf

1	# chmod 640 /etc/nagios/mysql.cnf

3.Создание пользователя с необходимыми привилегиями

mysql>grant PROCESS, SUPER, REPLICATION CLIENT on *.* to nagiosuser@'<IP-address-Nagios-server>' identified by 'nagiospassword';

1	mysql>grant PROCESS, SUPER, REPLICATION CLIENT on . to nagiosuser@'<IP-address-Nagios-server>' identified by 'nagiospassword';
