zabbix监控进程的CPU和内存占用量，进程数量
由于需要对公司特定服务进行监控，于是，通过编写脚本获取各个进程占用系统资源的信息，从而使用zabbix采集到这些数据进行特定进程的基础监控。
我这主要需要监控的程序如下：
nginx redis mysql tomcat sentinel mongodb openfire kafka zookeeper twemproxy mycat memcached php httpd
首先，在agent端编写监控脚本，脚本内容如下：
[root@monitor sbin]$ cat /data/zabbix/sbin/processstatus.sh
#!/bin/bash
#date:2015.06.15
nginxmem(){
ps aux|grep "nginx"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$6}; END{print sum}'
}
nginxcpu(){
ps aux|grep "nginx"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$3}; END{print sum}'
}

然后修改脚本的权限，使用：
chmod +x processstatus.sh
在zabbix_agentd.con.d/下面的配置文件中增加如下代码：
[9kgame@monitor zabbix_agentd.conf.d]$ cat /data/zabbix/etc/zabbix_agentd.conf.d/process_num_cpu_mem.conf #monitor process UserParameter=process.nginx.memory,/data/zabbix/sbin/processstatus.sh nginxmem UserParameter=process.nginx.cpu,/data/zabbix/sbin/processstatus.sh nginxcpu UserParameter=process.nginx.number,/data/zabbix/sbin/processstatus.sh nginxnum UserParameter=process.redis.memory,/data/zabbix/sbin/processstatus.sh redismem UserParameter=process.redis.cpu,/data/zabbix/sbin/processstatus.sh rediscpu UserParameter=process.redis.number,/data/zabbix/sbin/processstatus.sh redisnum UserParameter=process.mysql.memory,/data/zabbix/sbin/processstatus.sh mysqlmem UserParameter=process.mysql.cpu,/data/zabbix/sbin/processstatus.sh mysqlcpu UserParameter=process.mysql.number,/data/zabbix/sbin/processstatus.sh mysqlnum UserParameter=process.tomcat.memory,/data/zabbix/sbin/processstatus.sh tomcatmem UserParameter=process.tomcat.cpu,/data/zabbix/sbin/processstatus.sh tomcatcpu UserParameter=process.tomcat.number,/data/zabbix/sbin/processstatus.sh tomcatnum UserParameter=process.sentinel.memory,/data/zabbix/sbin/processstatus.sh sentinelmem UserParameter=process.sentinel.cpu,/data/zabbix/sbin/processstatus.sh sentinelcpu UserParameter=process.sentinel.number,/data/zabbix/sbin/processstatus.sh sentinelnum UserParameter=process.mongodb.memory,/data/zabbix/sbin/processstatus.sh mongodbmem UserParameter=process.mongodb.cpu,/data/zabbix/sbin/processstatus.sh mongodbcpu UserParameter=process.mongodb.number,/data/zabbix/sbin/processstatus.sh mongodbnum UserParameter=process.openfire.memory,/data/zabbix/sbin/processstatus.sh openfiremem UserParameter=process.openfire.cpu,/data/zabbix/sbin/processstatus.sh openfirecpu UserParameter=process.openfire.number,/data/zabbix/sbin/processstatus.sh openfirenum UserParameter=process.kafka.memory,/data/zabbix/sbin/processstatus.sh kafkamem UserParameter=process.kafka.cpu,/data/zabbix/sbin/processstatus.sh kafkacpu UserParameter=process.kafka.number,/data/zabbix/sbin/processstatus.sh kafkanum UserParameter=process.zookeeper.memory,/data/zabbix/sbin/processstatus.sh zookeepermem UserParameter=process.zookeeper.cpu,/data/zabbix/sbin/processstatus.sh zookeepercpu UserParameter=process.zookeeper.number,/data/zabbix/sbin/processstatus.sh zookeepernum UserParameter=process.twemproxy.memory,/data/zabbix/sbin/processstatus.sh twemproxymem UserParameter=process.twemproxy.cpu,/data/zabbix/sbin/processstatus.sh twemproxycpu UserParameter=process.twemproxy.number,/data/zabbix/sbin/processstatus.sh twemproxynum UserParameter=process.mycat.memory,/data/zabbix/sbin/processstatus.sh mycatmem UserParameter=process.mycat.cpu,/data/zabbix/sbin/processstatus.sh mycatcpu UserParameter=process.mycat.number,/data/zabbix/sbin/processstatus.sh mycatnum UserParameter=process.httpd.memory,/data/zabbix/sbin/processstatus.sh httpdmem UserParameter=process.httpd.cpu,/data/zabbix/sbin/processstatus.sh httpdcpu UserParameter=process.httpd.number,/data/zabbix/sbin/processstatus.sh httpdnum UserParameter=process.memcached.memory,/data/zabbix/sbin/processstatus.sh memcachedmem UserParameter=process.memcached.cpu,/data/zabbix/sbin/processstatus.sh memcachedcpu UserParameter=process.memcached.number,/data/zabbix/sbin/processstatus.sh memcachednum UserParameter=process.php.memory,/data/zabbix/sbin/processstatus.sh phpmem UserParameter=process.php.cpu,/data/zabbix/sbin/processstatus.sh phpcpu UserParameter=process.php.number,/data/zabbix/sbin/processstatus.sh phpnum
最后重启zabbix_agentd服务
service zabbix_agentd restart
然后在zabbix服务端使用zabbix_get看能否取到相应的数据，像下面这样就是成功获取到了数据。
[root@localhost zabbix]
# bin/zabbix_get -s 172.16.1.20 -p 10050 -k process.nginx.memory
184876
最后，需要在zabbix中定义模板。模板附件链接在下面。
zabbix模板下载
如果模板无法下载可以在附件中下载模板
需要注明的是内存取到的值得单位是KB，所以定义item的时候使用自定义倍数乘以1000，单位改成Byte，另外CPU占用率的值是带有小数点的一个数，所以在定义item的时候需要定义值得类型是浮点型，并且该值是占用逻辑单核的CPU占用率，所以需要定义自定义倍数，我实验中的服务器是2颗CPU，每颗CPU是8核16线程，所以自定义倍数是原来的基础上除以32，单位改成%就好。
下面是做好之后的显示效果：
注意这里MySQL占用cpu为0.0031%，表示占用1个核心的0.0031%，因为有32核心，所以mysql占总的cpu应该为
0.0031%*32=0.0992%
