在Ubuntu上设置Filebeat报警阈值,通常需结合Elastic Stack的Kibana来实现,步骤如下:
sudo apt-get update和sudo apt-get install filebeat进行安装。/etc/filebeat/filebeat.yml,确保配置了正确的日志输入和Elasticsearch输出,如output.elasticsearch: hosts: ["localhost:9200"]。filebeat.yml中添加xpack.enabled: true,以启用告警功能。"trigger": {"schedule": {"interval": "1m"}}。"condition": {"compare": {"ctx.payload.aggregations.log_count.value": {"gt": 100}}}。"actions": {"email": {"email": {"to": "your_email@example.com", "subject": "Alert", "body": "Threshold exceeded"}}}。
