Zabbix服务器对接器不连接到zabbix代理，反之亦然。

Question

这是我的docker-compose文件：

version: "3.7"

services:
  zookeeper:
    image: 'confluentinc/cp-zookeeper:latest'
    container_name: pooyesh-zookeeper
    ports: 
      - 2181:2181
    env_file: 
      - zookeeper.env  
  kafka:
    image: 'confluentinc/cp-kafka:latest'
    container_name: pooyesh-kafka
    env_file:
      - kafka.env
    ports: 
      - 9093:9093
    depends_on:
      - zookeeper

  postgres:
    image: 'postgres:latest'
    container_name: pooyesh-postgres
    env_file: 
      - postgres.env
    ports:
      - 5342:5432
    volumes: 
      - pooyesh-postgres:/var/lib/postgresql/data/
    
  zabbix-server:
    image: 'zabbix/zabbix-server-pgsql:latest'
    container_name: pooyesh-zabbix-server
    env_file: 
      - zabbix-server.env
    ports: 
      - 10051:10051
    depends_on: 
      - postgres
  zabbix-frontend:
    image: 'zabbix/zabbix-web-nginx-pgsql:latest'
    container_name: pooyesh-zabbix-frontend
    env_file: 
      - zabbix-frontend.env
    ports:
      - 8090:8080
    depends_on:
      - zabbix-server
      - postgres
  zabbix-agent:   # Zabbix agent service that tracks usage and send to zabbix server
    image: zabbix/zabbix-agent:latest
    container_name: pooyesh-zabbix-agent
    privileged: true   #access mode for allowing resource access
    environment:
      - ZBX_SERVER_HOST=zabbix-server #the IP/Dns of Zabbix server
    volumes:
      - pooyesh-zabbix-agent:/etc/zabbix/

volumes: 
  pooyesh-postgres:
  pooyesh-zabbix-agent:
  pooyesy-zabbix-server:

这些也是它们相关的env文件：

postgres.env

POSTGRES_USER=pooyesh
POSTGRES_PASSWORD=2110320982
POSTGRES_DB=pooyesh

zabbix-server.env

DB_SERVER_HOST=postgres
DB_SERVER_PORT=5432
POSTGRES_USER=pooyesh
POSTGRES_PASSWORD=2110320982
POSTGRES_DB=pooyesh
ZBX_TIMEOUT=10

zabbix-frontend.env

DB_SERVER_HOST=postgres
DB_SERVER_PORT=5432
POSTGRES_USER=pooyesh
POSTGRES_PASSWORD=2110320982
POSTGRES_DB=pooyesh
ZBX_SERVER_HOST=zabbix-server
ZBX_SERVER_PORT=10051

当我运行docker-组合文件时，这是我从pooyesh-zabbix-server容器中获得的日志：

213:20210929:180535.655 cannot send list of active checks to "172.18.0.3": host [9de9d2980576] not found
198:20210929:182416.233 item "Zabbix server:vfs.fs.size[/,pused]" became not supported: Value of type "string" is not suitable for value type "Numeric (unsigned)". Value "92.887666"

这也是我从pooyesh-zabbix-agent容器中获得的日志：

76:20210929:194155.572 active check configuration update from [zabbix-server:10051] started to fail (cannot resolve [zabbix-server])
    76:20210929:194255.588 active check configuration update from [zabbix-server:10051] is working again
    76:20210929:194255.588 no active checks on server [zabbix-server:10051]: host [23d448ba463e] not found

也许可以说，我有从这两个容器到另一个容器的telnet。例如，在pooyesh-zabbix-server上，我有telnet telnet zabbix-agent 10050

所有这些集装箱都在同一个码头组成的网络中，我不知道出了什么问题。我还放置了zabbix-server配置文件这里和zabbix-agent配置文件这里。

Answer 1

我终于能解决我的问题了。abbix-agent有一个名为ZBX_HOSTNAME的环境变量，它应该是zabbix主机选项卡中主机名的名称。在我的例子中，是Zabbix server。因此，当我将ZBX_HOSTNAME=Zabbix server添加到zabbix-agent的环境变量并将其依赖于zabbix-server时，一切都很好。
