Zabbix Server端配置文件说明(2)

#说明;zabbix初始化时占用多少系统共享内存用于存储配置信息，HOST,ITEM,TRIGGER数据，视监控主机数量和监控项调整，建议调整到32M或者更大

# CacheSize=8M

### Option: CacheUpdateFrequency

#   How often Zabbix will perform update of configuration cache, in seconds.

#

# Mandatory: no

# Range: 1-3600

# Default:

#说明：zabbix更新操作系统CACHE频率，若管理页面操作不频繁，可以考虑加大参数值

# CacheUpdateFrequency=60

### Option: StartDBSyncers

#   Number of pre-forked instances of DB Syncers

#

# Mandatory: no

# Range: 1-100

# Default:

#说明:将采集数据从CACHE同步到数据库线程数量，视数据库服务器I/O繁忙情况，和数据库写能力调整。数值越大，写能力越强。对数据库服务器I/O压力越大。

# StartDBSyncers=4

### Option: HistoryCacheSize

#   Size of history cache, in bytes.

#   Shared memory size for storing history data.

#

# Mandatory: no

# Range: 128K-2G

# Default:

#说明：用于设置划分多少系统共享内存用于存储采集的历史数据，此数值越大，数据库读压力越小

# HistoryCacheSize=8M

### Option: TrendCacheSize

#   Size of trend cache, in bytes.

#   Shared memory size for storing trends data.

#

# Mandatory: no

# Range: 128K-2G

# Default:

#说明：用于设置划分多少系统共享内存用于存储计算出来的趋势数据，此参数值从一定程度上可影响数据库读压力

# TrendCacheSize=4M

### Option: HistoryTextCacheSize

#   Size of text history cache, in bytes.

#   Shared memory size for storing character, text or log history data.

#

# Mandatory: no

# Range: 128K-2G

# Default:

#说明:指定划出多少系统共享内存用于存储 character, text or log history数据，若二级代理内存足够，建议可适当扩大此数值，可很大程度上解决系统I/O压力，和数据库读压力

# HistoryTextCacheSize=16M

### 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:

#说明：划出系统多少共享内存用于已请求的存储监控项信息，若监控项较多，建议加大此数值

# ValueCacheSize=8M

### Option: NodeNoEvents

#   If set to '1' local events won't be sent to master node.

#   This won't impact ability of this node to propagate events from its child nodes.

#

# Mandatory: no

# Range: 0-1

# Default:
