zabbix3.2监控rabbitmq集群

监控模板和脚本github地址：https://github.com/jasonmcintosh/rabbitmq-zabbix/tree/master/scripts/rabbitmq

.将rabbitmq监控相关的文件拷贝到/usr/local/zabbix_agents_3.2.0/scripts目录下

[root@eus_pe_web02:/usr/local/zabbix_agents_3.2.0/scripts]# ls -la rabbitmq/
total
drwxr-xr-x  root root   Oct  : .
drwxr-xr-x  root root   Oct  : ..
-rwxr-xr-x  root root  Oct  : api.py
-rwxr-xr-x  root root    Oct  : list_rabbit_nodes.sh
-rwxr-xr-x  root root    Oct  : list_rabbit_queues.sh

-rw-r--r--  root root    Oct  : .rab.auth
-rwxr-xr-x  root root    Oct  : rabbitmq-status.sh

.添加api配置文件(rabbitmq的账户信息)
.rab.auth

USERNAME=admin
PASSWORD=admin
CONF=/usr/local/zabbix_agents_3.2.0/conf/zabbix_agentd.conf
LOGLEVEL=INFO
LOGFILE=/var/log/zabbix/rabbitmq_zabbix.log
PORT=

.添加配置文件
[root@eus_pe_web02:/usr/local/zabbix_agents_3.2.0/scripts]# cat ../conf/zabbix_agentd/zabbix-rabbitmq.conf
UserParameter=rabbitmq.discovery_queues,/usr/local/zabbix_agents_3.2.0/scripts/rabbitmq/list_rabbit_queues.sh
UserParameter=rabbitmq.discovery_shovels,/usr/local/zabbix_agents_3.2.0/scripts/rabbitmq/list_rabbit_shovels.sh
UserParameter=rabbitmq.discovery_nodes,/usr/local/zabbix_agents_3.2.0/scripts/rabbitmq/list_rabbit_nodes.sh
UserParameter=rabbitmq[*],/usr/local/zabbix_agents_3.2.0/scripts/rabbitmq/rabbitmq-status.sh $ $ $

.导入rabbitmq模板

.重新启动zabbix-agent，并在被监控机器添加监控模板即可

上面的方法如果当rabbitmq的队列很多，自动发现会有几百个监控项，对服务器造成很大压力，有一种简单的方式获取队列

# 获取rabbitmq积压队列个数
UserParameter=queues_num,/usr/sbin/rabbitmqctl list_queues | grep -v delay | grep -v queues >> /tmp/rabbitmq.txt && awk '{total+=$2}END{print total}' /tmp/rabbitmq.txt

可以配置当队列数大于30或根据业务配置合适的值触发报警

上面的方法在zabbix_get的时候会报错

[root~]# zabbix_get -s 1.1.1.1 -k 'queues_num'
erlexec: HOME must be set
0

采用下面的方法获取队列

1.配置计划任务

# 3分钟获取一次rabbitmq的队列
*/3 * * * * /usr/sbin/rabbitmqctl list_queues | grep -v delay | grep -v queues > /tmp/rabbitmq.txt

2.配置item

UserParameter=queues_num,awk '{total+=$2}END{print total}' /tmp/rabbitmq.txt

# 有时候通过rabbitmqctl命令获取不到数据，此时我们可以通过 rabbitmqadmin 这个工具来输入账号密码来获取具体的信息
# cd /usr/bin/
# wget https://raw.githubusercontent.com/rabbitmq/rabbitmq-management/v3.7.8/bin/rabbitmqadmin

/usr/bin/rabbitmqadmin -H 1.1.1.1 -P 15672 -u rabbit -p 'pass' -f tsv -q list queues >> /tmp/rabbitmq.txt && awk '{total+=$2}END{print total}' /tmp/rabbitmq.txt

# 获取rabbitmq积压队列个数

可以配置当队列数大于30或根据业务配置合适的值触发报警

采用下面的方法获取队列

1.配置计划任务

*/3 * * * * /usr/bin/rabbitmqadmin -H 172.20.73.208 -P 15672 -u rabbit -p 'pass' -f tsv -q list queues > /tmp/rabbitmq.txt
