Zabbix報錯信息及遇到的問題

1.　頁面報錯  Error connecting to database: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

個人數據庫sock文件在這     /data/mysql/mysql.sock

[root@bash-5 ~]# mkdir /var/lib/mysql/

[root@bash-5 ~]# ln -s /data/mysql/mysql.sock /var/lib/mysql/mysql.sock  

[root@bash-5 ~]# ll /var/lib/mysql/mysql.sock  
lrwxrwxrwx 1 root root 22 Feb 14 19:30 /var/lib/mysql/mysql.sock -> /data/mysql/mysql.sock

 

2.　Zabbix ( proxy ) poller processes more than 75% busy 問題

一：重啓zabbix-server 結合定時任務

service zabbix-server restart

 crontab -e 新加一個定時任務：

@daily service zabbix-server restart > /dev/null 2>&1

 

二：編輯Zabbix Server的配置文件/etc/zabbix/zabbix_server.conf，找到配置StartPollers的段落：

### Option: StartPollers

#       Number of pre-forked instances of pollers.

#

# Mandatory: no

# Range: 0-1000

# Default:

# StartPollers=5

 直接在這增長一行：   StartPollers=10

 

Proxy的在這裏: 

### Option: StartProxyPollers
# Number of pre-forked instances of pollers for passive proxies.
#
# Mandatory: no
# Range: 0-250
# Default:
# StartProxyPollers=1
StartProxyPollers=5

將參數配置改爲多少取決於服務器的性能和監控的數量。內存足夠的話能夠設置高些

 

3.　Zabbix value cache working in low memory mode

[root@localhost zabbix] vi /etc/zabbix/zabbix_server.conf
### Option: CacheSize
# Size of configuration cache, in bytes.
# Shared memory size for storing host, item and trigger data.
#
# Mandatory: no
# Range: 128K-2G
# Default:
# CacheSize=8M
CacheSize=256M

[root@localhost zabbix]# systemctl restart zabbix-server

 

4.　Zabbix value cache working in low memory mode 

修改 zabbix_server.conf配置文件，定位到ValueCacheSize，而後調高ValueCacheSize大小，大小根據本身環境調整

### Option: ValueCacheSize
# Size of history value cache, in bytes.
# Shared memory size for caching item history data requests.
# Setting to 0 disables value cache.
#
# Mandatory: no
# Range: 0,128K-64G
# Default:
ValueCacheSize=64M       ####默認爲8M
