zabbix监控进程的CPU和内存占用量

fewrwe

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

首先，在agent端编写监控脚本，脚本内容如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141

[zabbix@localhost ~]$ cat zabbix-2.4.4/scripts/processstatus.sh #!/bin/bash #license:GPL #mail:admin@huxianglin.cn #date:2015.06.02 nginx(){ 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}' } redis(){     ps aux|grep "redis"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$6}; END{print sum}' } rediscpu(){     ps aux|grep "redis"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$3}; END{print sum}' } mysql(){     ps aux|grep "mysql"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$6}; END{print sum}' } mysqlcpu(){     ps aux|grep "mysql"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$3}; END{print sum}' } tomcat(){     ps aux|grep "tomcat"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$6}; END{print sum}' } tomcatcpu(){     ps aux|grep "tomcat"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$3}; END{print sum}' } sentinel(){     ps aux|grep "sentinel"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$6}; END{print sum}' } sentinelcpu(){     ps aux|grep "sentinel"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$3}; END{print sum}' } mongodb(){     ps aux|grep "mongod"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$6}; END{print sum}' } mongodbcpu(){     ps aux|grep "mongod"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$3}; END{print sum}' } openfire(){     ps aux|grep "openfire"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$6}; END{print sum}' } openfirecpu(){     ps aux|grep "openfire"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$3}; END{print sum}' } kafka(){     ps aux|grep "kafka"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$6}; END{print sum}' } kafkacpu(){     ps aux|grep "kafka"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$3}; END{print sum}' } zookeeper(){     ps aux|grep "zookeeper"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$6}; END{print sum}' } zookeepercpu(){     ps aux|grep "zookeeper"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$3}; END{print sum}' } twemproxy(){     ps aux|grep "twemproxy"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$6}; END{print sum}' } twemproxycpu(){     ps aux|grep "twemproxy"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$3}; END{print sum}' } mycat(){     ps aux|grep "mycat"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$6}; END{print sum}' } mycatcpu(){     ps aux|grep "mycat"|grep -v "grep"|grep -v "processstatus.sh"|awk '{sum+=$3}; END{print sum}' } case "$1" in nginx) nginx ;; nginxcpu) nginxcpu ;; redis) redis ;; rediscpu) rediscpu ;; mysql) mysql ;; mysqlcpu) mysqlcpu ;; tomcat) tomcat ;; tomcatcpu) tomcatcpu ;; sentinel) sentinel ;; sentinelcpu) sentinelcpu ;; mongodb) mongodb ;; mongodbcpu) mongodbcpu ;; openfire) openfire ;; openfirecpu) openfirecpu ;; kafka) kafka ;; kafkacpu) kafkacpu ;; zookeeper) zookeeper ;; zookeepercpu) zookeepercpu ;; twemproxy) twemproxy ;; twemproxycpu) twemproxycpu ;; mycat) mycat ;; mycatcpu) mycatcpu ;; *) echo "Usage: $0 {nginx|nginxcpu|redis|rediscpu|mysql|mysqlcpu|tomcat|tomcatcpu|sentinel|sentinelcpu|mongodb|mongodbcpu|openfire|openfirecpu|kafka|kafkacpu|zookeeper|zookeepercpu|twemproxy|twemproxycpu|mycat|mycatcpu}" esac

然后修改脚本的权限，使用：

chmod +x processstatus.sh

在zabbix_agentd.con配置文件中末尾增加如下代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

[zabbix@localhost ~]$ tail -23 zabbix-2.4.4/etc/zabbix_agentd.conf #monitor process UserParameter=process.nginx.memory,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh nginx UserParameter=process.nginx.cpu,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh nginxcpu UserParameter=process.redis.memory,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh redis UserParameter=process.redis.cpu,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh rediscpu UserParameter=process.mysql.memory,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh mysql UserParameter=process.mysql.cpu,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh mysqlcpu UserParameter=process.tomcat.memory,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh tomcat UserParameter=process.tomcat.cpu,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh tomcatcpu UserParameter=process.sentinel.memory,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh sentinel UserParameter=process.sentinel.cpu,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh sentinelcpu UserParameter=process.mongodb.memory,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh mongodb UserParameter=process.mongodb.cpu,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh mongodbcpu UserParameter=process.openfire.memory,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh openfire UserParameter=process.openfire.cpu,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh openfirecpu UserParameter=process.kafka.memory,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh kafka UserParameter=process.kafka.cpu,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh kafkacpu UserParameter=process.zookeeper.memory,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh zookeeper UserParameter=process.zookeeper.cpu,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh zookeepercpu UserParameter=process.twemproxy.memory,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh twemproxy UserParameter=process.twemproxy.cpu,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh twemproxycpu UserParameter=process.mycat.memory,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh mycat UserParameter=process.mycat.cpu,/home/zabbix/zabbix-2.4.4/scripts/processstatus.sh mycatcpu

最后重启zabbix_agentd服务

1 2	pkill zabbix zabbix-2.4.4/sbin/zabbix_agentd

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。

1 2	[iyunv@localhost zabbix-2.4.4]# 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。

百度云附件：zabbix模板.xml   

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。
