我创建一条规则
name: Metricbeat CPU Spike Rule
type: metric_aggregation
# How often ElastAlert will query Elasticsearch
# The unit can be anything from weeks to seconds
run_every:
minutes: 1
es_host: localhost
es_port: 9200
index: metricbeat-*
buffer_time:
hours: 1
metric_agg_key: system.cpu.user.pct
metric_agg_type: avg
query_key: beat.hostname
doc_type: metricsets
bucket_interval:
minutes: 5
sync_bucket_interval: true
#allow_buffer_time_overlap: true
#use_run_every_query_size: true
min_threshold: 0.5
filter:
- range:
system.cpu.user.pct:
from: 0.05
to: 0.07
# (Required)
# The alert is use when a match is found
alert:
- "email"
# (required, email specific)
# a list of email addresses to send alerts to
email:
- "[email protected]"
我认为该规则行之有效,因为当我尝试通过运行
elastalert-test-rule test.yaml
对其进行测试时,我得到了:Successfully loaded Metricbeat

Would have written the following documents to writeback index (default is elastalert_status):
silence - {'rule_name': u'Metricbeat.SenzoServer', '@timestamp': datetime.datetime(2018, 3, 20, 4, 38, 38, 277518, tzinfo=tzutc()), 'exponent': 0, 'until': datetime.datetime(2018, 3, 20, 4, 39, 38, 277508, tzinfo=tzutc())}
elastalert_status - {'hits': 155, 'matches': 16, '@timestamp': datetime.datetime(2018, 3, 20, 4, 38, 38, 279438, tzinfo=tzutc()), 'rule_name': 'Metricbeat', 'starttime': datetime.datetime(2018, 3, 19, 4, 38, 38, 173884, tzinfo=tzutc()), 'endtime': datetime.datetime(2018, 3, 20, 4, 38, 38, 173884, tzinfo=tzutc()), 'time_taken': 0.09930419921875}
所以然后我尝试使用
python -m elastalert.elastalert --verbose --rule test.yaml
运行它,我得到了:Traceback (most recent call last):

我的 flex 安装有问题吗?我尝试安装requirements.txt已经无法正常工作。
最佳答案
在命令i.s,config.yaml.example
的elastalert python -m elastalert.elastalert --verbose --rule example_rules/example_frequency.yaml --config config.yaml.example
中提及配置文件。
