module - Zabbix IBM MQM 可加载模块阻止 Zabbix Agent 服务

Question

我正在尝试测试 ZABBIX 的 IBM MQ 模块，所有代码都发布在 the ZABBIX share ，但是由于我是新手并且没有解释的步骤来做到这一点，所以我被卡住了。
所以我正在使用 ZABBIX 3.4 的源代码和 MQM 8 试用版的 header (在 Centos7 64 位上运行)。
首先，当我尝试编译文件 mq.c 时，有变量 argc 我认为它不应该存在!错误是这样的:

[root@osboxes dummy]# make
gcc -fPIC -shared -o mq.so mq.c -I../../../include -I/opt/mqm/inc
mq.c: In function ‘mq_q_depth’:
mq.c:61:9: error: ‘argc’ undeclared (first use in this function)
     if (argc > 1) strncpy(queue, param, (size_t)MQ_Q_NAME_LENGTH);
         ^
mq.c:61:9: note: each undeclared identifier is reported only once for each funct                              ion it appears in
make: *** [mq] Error 1

我在有 argc 的地方评论了这一行:

if (argc > 1) strncpy(queue, param, (size_t)MQ_Q_NAME_LENGTH);

编译成功，但是当我尝试在 ZABBIX 代理配置上上传模块时，代理无法启动并给我这个错误:

[root@osboxes dummy]# service zabbix-agent start

Job for zabbix-agent.service failed because a configured resource limit was exceeded. See "systemctl status zabbix-agent.service" and "journalctl -xe" for details.

我希望你能给我一些帮助。
谢谢

好的。因此，为 Zabbix 的 mq.c 编写代码的人很懒惰，并从他们的 qdepth.c 示例中复制了它。

I commented this line where there is the argc :

馊主意。看起来应该是:

if (request->nparam == 1) strncpy(queue, param, (size_t)MQ_Q_NAME_LENGTH);

我无法访问 Zabbix 的 SDK，所以这只是一个猜测。

Job for zabbix-agent.service failed because a configured resource limit was exceeded. See "systemctl status zabbix-agent.service" and "journalctl -xe" for details.

嗯，错误信息很清楚。是时候阅读文档/手册来了解最低资源设置或推荐资源设置了，因为您显然没有足够的资源来运行所有内容。
