ZABBIX web端 显示 server 运行状态 不

一 环境

1.1 操做系统

[root@host-xxxsoft]# lsb_release -a
LSB Version:    :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID: CentOS
Description:    CentOS release 6.6 (Final)
Release:        6.6
Codename:       Final
[root@host-xxx soft]# 

1.2 zabbix 版本 agent 和server 以及webfront 都市2.4.6

[wls81@host-xxxx sbin]$ ./zabbix_agent --version
Zabbix agent v2.4.6 (revision 54796) (10 August 2015)
Compilation time: Nov  2 2015 21:29:13
 

1.3 目前我这边监控了791台虚拟机

二 问题

特此说明：此问题不是zabbix web页面　出现红色的　zabbix server is not running

2.1 web 端

页面显示zabbix_server 不在运行

zabbixserver 还报以下错误

Less than 25% free in the trends cache

2.2 agent 端日志

 28079:20161012:121243.196 active check configuration update from [192.168.176.25:10051] started to fail (cannot connect to [[192.168.176.25]:10051]: [4] Interrupted system call)
 28079:20161012:122102.894 active check configuration update from [192.168.176.25:10051] is working again

 28079:20161012:160811.493 active check configuration update from [192.168.176.25:10051] started to fail (ZBX_TCP_READ() failed: [4] Interrupted system call)
 28079:20161013:104855.178 active check configuration update from [192.168.176.25:10051] is working again

而且  从agent端　telent server端 10051 不通

2.3 zabbix server

zabbix_server 进程是活的，端口10051 也是监听的。

 

三解决思路 

仍是看日志 

最后是定位这个配置，默认小了致使的。

### Option: TrendCacheSize #       Size of trend cache, in bytes. #       Shared memory size for storing trends data. # # Mandatory: no # Range: 128K-2G # Default: # TrendCacheSize=4M  TrendCacheSize=400M
