Zabbix報錯:"Zabbix http poller processes more than 75% busy"的解決

1、釘釘收到告警

主機名稱：Zabbix服務端-172.28.18.75
IP地址 ：127.0.0.1
告警時間：2019.10.22 13:34:39
告警信息：Zabbix http poller processes more than 75% busy
告警級別：Average
檢查項 ：zabbix[process,http poller,avg,busy]
當前狀態：PROBLEM
值=100 %
故障已持續8m

Zabbix的http輪詢實例告警

2、修改配置文件

http poller processes跟配置文件中的StartHTTPPollers參數相關

打開配置文件搜索:StartHTTPPollers

[root@zabbix_server etc]# vim zabbix_server.conf

241 
242 ### Option: StartHTTPPollers
243 #   Number of pre-forked instances of HTTP pollers.
244 #
245 # Mandatory: no
246 # Range: 0-1000
247 # Default:
248 # StartHTTPPollers=1

系統仍是默認配置，初始實例數爲1，修改成10

242 ### Option: StartHTTPPollers
243 #   Number of pre-forked instances of HTTP pollers.
244 #
245 # Mandatory: no
246 # Range: 0-1000
247 # Default:
248 # StartHTTPPollers=1
249 StartHTTPPollers=10

3、重啓Zabbix_server服務

[root@zabbix_server etc]# service zabbix_server restart
Shutting down zabbix_server: [肯定]
Starting zabbix_server:  [肯定]
[root@zabbix_server etc]# 

4、再次查看最新監控數據

 http poller 這一項最新數據已經降到17.18%了，告警解決。

 

5、Zabbix性能告警項對應的配置文件參數

當某個進程負載太高時調整相應的值：

Zabbix busy trapper processes, in % StartTrappers=5 
Zabbix busy poller processes, in % StartPollers=5 
Zabbix busy ipmi poller processes, in % StartIPMIPollers=0 
Zabbix busy discoverer processes, in % StartDiscoverers=1 
Zabbix busy icmp pinger processes, in % StartPingers=1 
Zabbix busy http poller processes, in % StartHTTPPollers=1 
Zabbix busy proxy poller processes, in % StartProxyPollers=1 
Zabbix busy unreachable poller processes, in % StartPollersUnreachable=1 
Zabbix busy java poller processes, in % StartJavaPollers=0 
Zabbix busy snmp trapper processes, in % StartSNMPTrapper=0 
Zabbix busy vmware collector processes, in % StartVMwareCollectors=0

當某項buffer不夠時增大容量到合適的值：

Zabbix-server: Zabbix trend write cache, % free TrendCacheSize=4M 
Zabbix-server: Zabbix configuration cache, % free CacheSize=8M 
Zabbix-server: Zabbix text write cache, % free HistoryTextCacheSize=16M 
Zabbix-server: Zabbix history write cache, % free HistoryCacheSize=8M 
Zabbix-server: Zabbix value cache, % free ValueCacheSize=8M 
Zabbix-server: Zabbix vmware cache, % free VMwareCacheSize=8M
