新部署的zabbix服务器，上线后在mointoring 页面就有“Too many processes on Zabbix server”的告警。在网上查看了很多资料没能解决。只能按照经验处理
1 ps -axf 查看进程情况，观察一下什么进程比较多。

观察我自己的服务器的时候，发现进程最多的居然就是zabbix自己的服务。
2 按照以往的经验，服务启动的进程数应该都可以在配置文件中配置。于是查看zabbix的配置文件，果然找到类似配置参数
#高级参数
### Option: StartPollers
# Number of pre-forked instances of pollers.
#
# Mandatory: no
# Range: 0-1000
# Default:
#说明;初始化时，启动子进程数量，数量越多，则服务端吞吐能力越强，对系统资源消耗越大
# StartPollers=5
### Option: StartDiscoverers
# Number of pre-forked instances of discoverers.
#
# Mandatory: no
# Range: 0-250
# Default:
说明：用于设置自动发现主机的线程数量，若单台代理所管理机器超过500台，可以考虑加大此数值（仅适用于直接AGENT场景）
# StartDiscoverers=1
类似以上的一些参数，具体情况要看ps的结果来对照参数处理。我的这些参数不知道什么原因导致的，都特别的高，实际上应该按照需要调整。
把对应进程的参数调整好后，重启zabbix服务即可解决问题。
