自定义elastalert插件收到的弹性搜索警报中的信息

Question

我已经使用elasticsearch主机配置了elastalert实例.我还创建了一个示例规则,它将在日志中匹配该模式时检查loglevel和alert.

一切都工作正常,我正在收到我的松弛通道上的警报.

唯一关心的是我收到的警报中的信息/数据.elastalert插件发送与我正在寻找的模式相关的所有属性; 但我对所有信息都不感兴趣.我所关心的只是一些特定的属性.

以下是我的规则示例:

# Alert when the rate of events exceeds a threshold

# (Optional)
# Elasticsearch host
 es_host: 

# (Optional)
# Elasticsearch port
 es_port: 

# (OptionaL) Connect with SSL to elasticsearch
#use_ssl: True

# (Optional) basic-auth username and password for elasticsearch
#es_username: someusername
#es_password: somepassword

# (Required)
# Rule name, must be unique
 name: DB2 test Rule

# (Required)
# Type of alert.
# the frequency rule type alerts when num_events events occur with timeframe time
 type: frequency

# (Required)
# Index to search, wildcard supported
 index: logstash-* # logstash-2016.04.05 #logstash-YYYY.MM.DD # logstash-*

# (Required, frequency specific)
# Alert when this many documents matching the query occur within a timeframe
 num_events: 1

# (Required, frequency specific)
# num_events must occur within this amount of time to trigger an alert
 timeframe:
  hours: 12

# (Required)
# A list of elasticsearch filters used for find events
# These filters are joined with AND and nested in a filtered query
# For more info: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl.html
 filter:
 - query:
    query_string:
      query: "type: db2 AND logLevel: Warning"

# (Required)
# The alert is use when a match is found
 alert:
 - "slack"
 slack:
 slack_webhook_url: "XYZ"

我在松弛频道上收到的警报看起来像这样:

DB2 test Rule
DB2 test Rule

At least 1 events occurred between 2016-04-29 07:51 UTC and 2016-04-29 19:51 UTC

@timestamp: 2016-04-29T19:51:45.940Z
@version: 1
_id: 
_index: logstash-2016.04.29
_type: db2
apphdl: 
appid: 
authid: 
day: 29
db: NEO
eduid: 
eduname: 
function: 
host: 
hostname: 
hour: 14
id: 
instance: 
logLevel: Warning
logMessage: 
LOADID: 
DATA #2 : 
Completed 
message:       LEVEL: Warning

和ETC等......

我想自定义此警报消息,以便它仅提醒我关注的那些属性.(对于ex时间轴,loglevel和其他几个.)

有没有办法做到这一点？我们非常感谢您的一点帮助或指导.

根据ElastAlert文档,您可以将警报限制为仅包含文档中的某些字段include.

在你的情况下,它将是:

include: ["@timestamp", "logLevel", "message"]
