Zabbix 历史数据存储到 Elasticsearch

Zabbix 3.4.6 版本开始支持历史数据存储到 Elasticsearch, 早就想测试这个功能，最近有个需求需保存 zabbix 的历史数据上达十亿条，因此决定测试这功能的实用性，事实证明确实效果挺好。从今以后 zabbix 也支持大量的历史数据。

安装 elasticsearch

这里就不说明安装教程了，详情请参考以前的教程

添加 Elasticsearch mapping

Elasticsearch 支持 Zabbix 的监控项类型：uint，dbl，str，log，text，对应如下

Zabbix 监控项数据类型	对应 Zabbix 表	对应 Elasticsearch 类型
Numeric(unsigned)(无符号整型)	history_uint	uint
Numeric(float)（浮点型）	history	dbl
Character（字符）	history_str	str
Log（日志）	history_log	log
Text	history_text	text

# curl -H "Content-Type:application/json" -XPUT http://192.168.1.231:9200/uint -d ' { "settings" : { "index" : { "number_of_replicas" : 1, "number_of_shards" : 5 } }, "mappings" : { "values" : { "properties" : { "itemid" : { "type" : "long" }, "clock" : { "format" : "epoch_second", "type" : "date" }, "value" : { "type" : "long" } } } } } '

# curl -H "Content-Type:application/json" -XPUT http://192.168.1.231:9200/dbl -d ' { "settings" : { "index" : { "number_of_replicas" : 1, "number_of_shards" : 5 } }, "mappings" : { "values" : { "properties" : { "itemid" : { "type" : "long" }, "clock" : { "format" : "epoch_second", "type" : "date" }, "value" : { "type" : "double" } } } } } '

# curl -H "Content-Type:application/json" -XPUT http://192.168.1.231:9200/log -d ' { "settings" : { "index" : { "number_of_replicas" : 1, "number_of_shards" : 5 } }, "mappings" : { "values" : { "properties" : { "itemid" : { "type" : "long" }, "clock" : { "format" : "epoch_second", "type" : "date" }, "value" : { "fields" : { "analyzed" : { "index" : true, "type" : "text", "analyzer" : "standard" } }, "index" : false, "type" : "text" } } } } } '

# curl -H "Content-Type:application/json" -XPUT http://192.168.1.231:9200/text -d ' { "settings" : { "index" : { "number_of_replicas" : 1, "number_of_shards" : 5 } }, "mappings" : { "values" : { "properties" : { "itemid" : { "type" : "long" }, "clock" : { "format" : "epoch_second", "type" : "date" }, "value" : { "fields" : { "analyzed" : { "index" : true, "type" : "text", "analyzer" : "standard" } }, "index" : false, "type" : "text" } } } } } '

# curl -H "Content-Type:application/json" -XPUT http://192.168.1.231:9200/str -d ' { "settings" : { "index" : { "number_of_replicas" : 1, "number_of_shards" : 5 } }, "mappings" : { "values" : { "properties" : { "itemid" : { "type" : "long" }, "clock" : { "format" : "epoch_second", "type" : "date" }, "value" : { "fields" : { "analyzed" : { "index" : true, "type" : "text", "analyzer" : "standard" } }, "index" : false, "type" : "text" } } } } } '

配置 zabbix 服务器

Zabbix 安装过程忽略

配置 zabbix_server.conf 文件

在 /etc/zabbix/zabbix_server.conf 文件下添加 elasticsearch 配置，指定历时数据使用 elasticsearch。 vim /etc/zabbix/zabbix_server.conf

HistoryStorageURL=http://192.168.1.231:9200

HistoryStorageTypes=uint,dbl,str,log,text

配置 zabbix.conf.php 文件在 /etc/zabbix/web/zabbix.conf.php 文件下添加 elasticsearch 配置 vim /etc/zabbix/zabbix_server.conf

// Elasticsearch url (can be string if same url is used for all types).

$HISTORY['url'] = 'http://192.168.1.231:9200';

// Value types stored in Elasticsearch.

$HISTORY['types'] = ['uint', 'text', 'log', 'str', 'dbl'];

多台 elasticsearch 集群可按以下格式配置

$HISTORY['url'] = [ 'uint' => 'http://192.168.1.230:9200 ', 'text' => 'http://192.168.1.234:9200', 'log' => 'http://192.168.1.235:9200'];

$HISTORY['types'] = ['uint', 'text','log'];

验证数据

启动 zabbix 后，使用 kibana 查看 es 集群是否有相关索引，方法这里就忽略。
