mysql与nagios的结合使用

一、 对mysql建库建表，并测试数据

基本信息：
库名：nh_nagios
表名：nagios_alerts

[root@nhserver2 ~]# mysql -u root -p
Enter password:123456

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| cactidb            |
| mysql              |
| test               |
+--------------------+
5 rows in set (0.00 sec)

mysql> create database nh_nagios;

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| cactidb            |
| mysql              |
| nh_nagios          |
| test               |
+--------------------+
5 rows in set (0.00 sec)

mysql> use nh_nagios
Database changed

mysql> create table nagios_alerts
    -> (
    ->  nagios_id int not null auto_increment,
    ->  nagios_name char(50) not null,
    ->  nagios_number int not null,
    ->  primary key(nagios_id)
    -> )engine=innod default charset=utf8 auto_increment=1;
Query OK, 0 rows affected, 2 warnings (0.00 sec)

mysql> show tables;
+---------------------+
| Tables_in_nh_nagios |
+---------------------+
| nagios_alerts       |
+---------------------+
1 row in set (0.00 sec)

mysql> INSERT INTO nagios_alerts (nagios_name,nagios_number)  VALUES("serviceTotalsPROBLEMS",2);
Query OK, 1 row affected (0.00 sec)

mysql> select * from nagios_alerts;
+-----------+-----------------------+---------------+
| nagios_id | nagios_name           | nagios_number |
+-----------+-----------------------+---------------+
|         1 | serviceTotalsPROBLEMS |             2 |
+-----------+-----------------------+---------------+
1 row in set (0.00 sec)

mysql> INSERT INTO nagios_alerts (nagios_name,nagios_number)  VALUES("serviceTotalsPROBLEMS",10);
Query OK, 1 row affected (0.00 sec)

mysql> select * from nagios_alerts;
+-----------+-----------------------+---------------+
| nagios_id | nagios_name           | nagios_number |
+-----------+-----------------------+---------------+
|         1 | serviceTotalsPROBLEMS |             2 |
|         2 | serviceTotalsPROBLEMS |            10 |
+-----------+-----------------------+---------------+
2 rows in set (0.00 sec)

mysql> exit

二、在shell中执行插入数据进mysql的测试

[root@nhserver2 ~]# vim show_nh_nagios_alerts.sh
#!/bin/bash
mysql -uroot -hlocalhost -p123456 <<EOF
        use nh_nagios;
        #select * from nagios_alerts;
        INSERT INTO nagios_alerts (nagios_name,nagios_number)  VALUES("serviceTotalsPROBLEMS",30);
EOF

[root@nhserver2 ~]# chmod 700 show_nh_nagios_alerts.sh

[root@nhserver2 ~]# ./show_nh_nagios_alerts.sh
nagios_id       nagios_name     nagios_number
1       serviceTotalsPROBLEMS   2
2       serviceTotalsPROBLEMS   10

[root@nhserver2 ~]# mysql -u root -p
Enter password:123456

mysql> use nh_nagios
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> select * from nagios_alerts;
+-----------+-----------------------+---------------+
| nagios_id | nagios_name           | nagios_number |
+-----------+-----------------------+---------------+
|         1 | serviceTotalsPROBLEMS |             2 |
|         2 | serviceTotalsPROBLEMS |            10 |
|         3 | serviceTotalsPROBLEMS |            30 |
+-----------+-----------------------+---------------+
3 rows in set (0.00 sec)

mysql> exit

使用语句自动取nagios_number的数据，即nagios内serviceTotalsPROBLEMS的值
[root@nhserver2 ~]# vim 1.sh
#! /bin/sh
alerts=`curl -u nagiosadmin:password -s http://192.168.5.10/nagios/cgi-bin/status.cgi?host=all | \
grep serviceTotalsPROBLEMS |\
grep -o '[[:digit:]]'`
if [ "$alerts" = "" ]
then
        echo "alerts is empty"
else
        echo $alerts
fi

[root@nhserver2 ~]# ./1.sh
2
测试成功

[root@nhserver2 ~]# vim show_nh_nagios_alerts.sh
#!/bin/bash
test_get_nagios_service_alerts=`curl -u nagiosadmin:password -s http://192.168.5.10/nagios/cgi-bin/status.cgi?host=all | \
grep serviceTotalsPROBLEMS |\
grep -o '[[:digit:]]'`

#此处加入判断当无报警时，设get_nagios_service_alerts=0
if [ "$test_get_nagios_service_alerts" = "" ];
then
        get_nagios_service_alerts=0
else
        get_nagios_service_alerts=$test_get_nagios_service_alerts
fi

mysql -uroot -hlocalhost -p123456 <<EOF
        use nh_nagios;
        #select * from nagios_alerts;
        INSERT INTO nagios_alerts (nagios_name,nagios_number)  VALUES("serviceTotalsPROBLEMS",$get_nagios_service_alerts);
EOF

写入3条数据进mysql中
[root@nhserver2 ~]# ./show_nh_nagios_alerts.sh
[root@nhserver2 ~]# ./show_nh_nagios_alerts.sh
[root@nhserver2 ~]# ./show_nh_nagios_alerts.sh

[root@nhserver2 ~]# mysql -u root -p
Enter password:123456

mysql> use nh_nagios
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed

mysql> select * from nagios_alerts;
+-----------+-----------------------+---------------+
| nagios_id | nagios_name           | nagios_number |
+-----------+-----------------------+---------------+
|         1 | serviceTotalsPROBLEMS |             2 |
|         2 | serviceTotalsPROBLEMS |            10 |
|         3 | serviceTotalsPROBLEMS |            30 |
|         4 | serviceTotalsPROBLEMS |             2 |
|         5 | serviceTotalsPROBLEMS |             2 |
|         6 | serviceTotalsPROBLEMS |             2 |
|         7 | serviceTotalsPROBLEMS |             2 |
|         8 | serviceTotalsPROBLEMS |             2 |
|         9 | serviceTotalsPROBLEMS |             1 |
|        10 | serviceTotalsPROBLEMS |             1 |
|        11 | serviceTotalsPROBLEMS |             1 |
|        12 | serviceTotalsPROBLEMS |             1 |
|        13 | serviceTotalsPROBLEMS |             0 |
|        14 | serviceTotalsPROBLEMS |             0 |
|        15 | serviceTotalsPROBLEMS |             0 |
|        16 | serviceTotalsPROBLEMS |             0 |
|        17 | serviceTotalsPROBLEMS |             0 |
|        18 | serviceTotalsPROBLEMS |             0 |
|        19 | serviceTotalsPROBLEMS |             0 |
|        20 | serviceTotalsPROBLEMS |             0 |
|        21 | serviceTotalsPROBLEMS |             2 |
|        22 | serviceTotalsPROBLEMS |             2 |
|        23 | serviceTotalsPROBLEMS |             0 |
|        24 | serviceTotalsPROBLEMS |             0 |
|        25 | serviceTotalsPROBLEMS |             0 |
|        26 | serviceTotalsPROBLEMS |             2 |
|        27 | serviceTotalsPROBLEMS |             2 |
|        28 | serviceTotalsPROBLEMS |             2 |
|        29 | serviceTotalsPROBLEMS |             2 |
|        30 | serviceTotalsPROBLEMS |             2 |
+-----------+-----------------------+---------------+
30 rows in set (0.00 sec)

mysql> exit

到此，通过shell写入nagios的数据进mysql成功。后继可考虑将shell写入cron，让它每隔一分钟就写入数据进mysql中。

三、取服务状态为CRITICAL的IP地址与服务名

[root@nhserver2 ~]# curl -u nagiosadmin:password -s http://192.168.5.10/nagios/cgi-bin/status.cgi?host=all | grep CRITICAL | \
grep -E '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' > nagios.txt

[root@nhserver2 ~]# cat nagios.txt
<TD ALIGN=LEFT valign=center CLASS='statusBGCRITICAL'><A HREF='extinfo.cgi?type=2&host=192.168.5.110&service=SSH'>SSH</A></TD></TR>
<TD ALIGN=LEFT valign=center CLASS='statusBGCRITICAL'><A HREF='extinfo.cgi?type=2&host=192.168.5.110&service=check-host-alive'>check-host-alive</A></TD></TR>

[root@nhserver2 ~]# awk -F'&' '{print $2,$3}' nagios.txt
host=192.168.5.110 service=SSH'>SSH</A></TD></TR>
host=192.168.5.110 service=check-host-alive'>check-host-alive</A></TD></TR>

[root@nhserver2 ~]# awk -F'&' '{print $2,$3}' nagios.txt | sed 's#</A></TD></TR>##g'
host=192.168.5.110 service=SSH'>SSH
host=192.168.5.110 service=check-host-alive'>check-host-alive

[root@nhserver2 ~]# awk -F'&' '{print $2,$3}' nagios.txt | sed 's#</A></TD></TR>##g' | sed "s#\'>.*##g"
host=192.168.5.110 service=SSH'>SSH
host=192.168.5.110 service=check-host-alive'>check-host-alive

[root@nhserver2 ~]# awk -F'&' '{print $2,$3}' nagios.txt | sed 's#</A></TD></TR>##g' | sed "s#\'>.*##g" > nagios2.txt

[root@nhserver2 ~]# cat nagios2.txt
host=192.168.5.110 service=SSH'>SSH
host=192.168.5.110 service=check-host-alive'>check-host-alive

[root@nhserver2 ~]# sed "s/'>.*$//g" nagios2.txt
host=192.168.5.110 service=SSH
host=192.168.5.110 service=check-host-alive

四、对nagios_alerts表加入一记录生成时间的字段，并成功记录数据

#新增一生成时间字段
mysql> alter table nagios_alerts add COLUMN createtime datetime NOT NULL;
Query OK, 0 rows affected (0.06 sec)
Records: 0  Duplicates: 0  Warnings: 0

#查看表结构
mysql> show columns from nagios_alerts;
+---------------+----------+------+-----+---------+----------------+
| Field         | Type     | Null | Key | Default | Extra          |
+---------------+----------+------+-----+---------+----------------+
| nagios_id     | int(11)  | NO   | PRI | NULL    | auto_increment |
| nagios_name   | char(50) | NO   |     | NULL    |                |
| nagios_number | int(11)  | NO   |     | NULL    |                |
| createtime    | datetime | NO   |     | NULL    |                |
+---------------+----------+------+-----+---------+----------------+
4 rows in set (0.04 sec)

========================================

#生成时间的shell，但在mysql中，可以使用NOW()函数来做
[root@nhserver2 ~]# var=`date "+%Y-%m-%d %H:%M:%-S"`
[root@nhserver2 ~]# echo $var
2014-03-30 21:36:53
========================================

[root@nhserver2 ~]# vim show_nh_nagios_alerts.sh
#!/bin/bash
test_get_nagios_service_alerts=`curl -u nagiosadmin:skylink -s http://192.168.5.10/nagios/cgi-bin/status.cgi?host=all | \
grep serviceTotalsPROBLEMS |\
grep -o '[[:digit:]]'`

create_time=`date "+%Y-%m-%d%H:%M:%-S"`

if [ "$test_get_nagios_service_alerts" = "" ];
then
        get_nagios_service_alerts=0
else
        get_nagios_service_alerts=$test_get_nagios_service_alerts
fi

mysql -uroot -hlocalhost -p123456 <<EOF
        use nh_nagios;
        #select * from nagios_alerts;
        INSERT INTO nagios_alerts (nagios_name,nagios_number,createtime)  VALUES("serviceTotalsPROBLEMS",$get_nagios_service_alerts,NOW()); #加入生成时间
EOF

====================================

#显示表内容

[root@nhserver2 ~]# vim show_nh_nagios_alerts_mysql.sh

#!/bin/bash
mysql -uroot -hlocalhost -p123456 <<EOF
        use nh_nagios;
        select * from nagios_alerts;
EOF
