# 1. 报错描述： #

打开`apache`的状态页面正常：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNjUyMjA5OQ_size_16_color_FFFFFF_t_70]  
但是配置apache模板后，并给相应的远程主机添加apache的监控模板，发现监控项大部分都是不支持！！！

查看服务端的zabbix日志文件，发现报错，监控项显示不支持，如图：

回想一下，为了监控客户端上的`apache`服务，我们在apache的配置文件中添加了一个apache状态的页面，然后使用已经定义好的模板来进行监控的，那么出问题了，那不是**apache状态页面的问题**就是**zapache模板的问题**。  
而从第一张图，可以看到`apache`状态页面是可以访问的，那就**只可能是zapache的问题**了。

# 3. 验证结果 #

把原来的`apache`模板删除掉，重新导入。并为对应的主机添加该模板。  
查看最新数据：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNjUyMjA5OQ_size_16_color_FFFFFF_t_70 4]  
没最新数据，刷新多几次`apache`监控状态页面。然后点击“应用”。或者等一会也行。  
从下图可以看到，已经有最新的监控数据了。

随便点一个图形，可以看到已经出图了。虽然只有一点点。

至此，监控远程主机的`apache`服务终于成功了。
