我已经用我的 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日志级别和警报。
一切正常,我在我的松弛频道上正确收到警报。
唯一担心的是我收到的警报中的信息/数据。elastalert 插件正在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。我只关心一些特定的属性。
这是我的规则的一个例子:
# 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 Slack 频道上收到的警报如下所示:
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 ETC...
我想自定义此警报消息,以便它仅向我提醒我关心的那些属性。(对于前时间线、日志级别等。)
有没有办法做到这一点?非常感谢您提供一点帮助或追求的方向。
