nagios监控日志脚本check_logfile

2025-02-06 技术教程

nagios 自带的Plugin check_log监控日志比较单一，对于对日志监控比较高的生产环境下还是不行的。consol.de 出的check_logfile很不错很强大，支持正则表达式。详细官方说明如下:http://labs.consol.de/lang/de/nagios/check_logfiles/我以监控apache日志为例说明下这个怎么用。wgethttp://labs.consol.de/wp-content/uploads/2012/02/check_logfiles-3.4.7.1.tar.gz
tar xf check_logfiles-3.4.7.1.tar.gz
cd check_logfiles-3.4.7.1
./configure --prefix=/usr/local/nagios/ --with-nagios-user=nagios --with-nagios-group=nagios --with-seekfiles-dir=/usr/local/nagios/var/tmp/ --with-protocols-dir=/usr/local/nagios/var/tmp/ --with-perl=/usr/bin/perl --with-gzip=/bin/gzip
make && make install

#我们利用调用文件来监控，这样方便些
#创建log.conf
vim /usr/local/nagiso/etc/log.conf
@searches = (
{
tag => 'test_http',
logfile => '/var/log/httpd/access_log',
rotation => 'CentOs',
criticalpatterns => [
'.*401\s*571.*',

],
warningpatterns => [
'404'
]

},
);
#具体的详细配置可以看下官方介绍
在nrpe添加
command[check_logfiles]=/usr/local/nagios/libexec/check_logfiles --config=/usr/local/nagios/etc/log.cfg

#执行

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d好了被监控端配置完成了
