監控系統nagios+nconf+pnp4

配置Nconf管理NAGIOS更簡單且效率更高

參照上一篇NAGIOS之SNMP方式監控系統的博文,安裝好LAMP環境和NAGIOS.

一.本文的案例所需軟件

nconf-1.2.6-0.tgz

pnp4nagios-0.6.18.tar.gz

NSCLIENT++

cgilib-0.6.tar.gz

rrdtool

pnp4nagios-0.6.7.tar.gz

二.安裝nconf

1.解壓安裝包

tar -xf nconf-1.2.6-0.tgz -C /var/www/html/

2.配置nconf所需的數據庫級授權用戶

mysql> CREATE DATABASE nconf;
Query OK, 1 row affected (0.01 sec)

mysql> GRANT ALL ON nconf.* TO 'nconf'@'localhost' IDENTIFIED BY 'nconf';
Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

3.修改目錄用戶權限

chown -R apache.apache config/ temp/ static_cfg/ output/

4.訪問nconf http://ip/nconf

…………

5.按照需求刪除以安裝文件

6.測試登錄

二.配置NCONF

1.無法連接數據庫

2.配置NCONF鏈接數據庫及執行腳本

ln -s /usr/local/nagios/bin/nagios bin/nagios
chmod +x /var/www/html/nconf/bin/generate_config.pl
chown -R apache.apache bin/
chmod +x /usr/local/nagios/bin/nagios
chmod +x /var/www/html/nconf/ADD-ONS/deploy_local.sh

vim /var/www/html/nconf/ADD-ONS/deploy_local.sh //根據環境修改裏面的nagios路徑,此處無需修改

3.執行腳本,在/usr/local/nagios/etc/下生成兩個目錄Default_collector 與global 用於存放通用nconf定義的監控資源

cd ADD-ONS/
./deploy_local.sh
Running configuration check...done.
Reloading nagios configuration...done

4.添加至crontab中讓其每隔一分鐘執行一次

*/1 * * * * /bin/sh /var/www/html/nconf/ADD-ONS/deploy_local.sh

5.修改nagios.cfg配置文件加註釋,添加如下兩行

vim /usr/local/nagios/etc/nagios.cfg

6.重啓Nagios

7.以上Nconf 配置完成,安裝客戶端手動添加監控資源測試

8.在被監控機上安裝Windows客戶端.

9.配置ini文件填入nagios地址,後重啓客戶端

10.添加監控資源

11.此處省略只列出各屬性的參數值

CPU

Memory

12.自定義端口

13.配置郵件告警,將等三方程序sendEmail 傳入監控機並添加執行權限(用法請參考上一篇NAGIOS之SNMP監控的博文,這裏不再贅述)

14.分別填入以下內容

/usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/local/bin/sendEmail -f [email protected] -t $CONTACTEMAIL$ -s 1.1.1.1 -u "** $NOTIFICATIONTYPE$ Address: $HOSTADDRESS$ is $HOSTSTATE$ **"

/usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /usr/local/bin/sendEmail -f [email protected] -t $CONTACTEMAIL$ -s 1.1.1.1 -u "** $NOTIFICATIONTYPE$ Address:$HOSTADDRESS$ ServiceAlert:$SERVICEDESC$ is $SERVICESTATE$ **"

15.測試郵件通知功能,這裏先定義參數值爲20 警告,30嚴重 (郵件通知有點延遲)
