Filebeat 本身不直接提供报警功能,但你可以结合其他工具(如Elasticsearch的Watcher、Logstash的Output插件等)来实现报警功能。以下是一个使用Elasticsearch的Watcher来设置报警规则的示例:
在Kibana中,打开Dev Tools控制台,创建一个新的Watcher。
PUT _watcher/watch/your-watch-name
{
"trigger": {
"schedule": {
"interval": "1m"
}
},
"input": {
"search": {
"request": {
"indices": ["your-index-name"],
"body": {
"query": {
"bool": {
"must": [
{
"match": {
"your-field-name": "your-expected-value"
}
}
]
}
}
}
}
}
},
"condition": {
"compare": {
"ctx.payload.hits.total": {
"gt": 0
}
}
},
"actions": {
"email_admin": {
"email": {
"to": "admin@example.com",
"subject": "Filebeat Alert",
"body": "Alert triggered! There are new logs matching the criteria."
}
}
}
}
确保Filebeat配置文件(通常是/etc/filebeat/filebeat.yml)中正确配置了Elasticsearch的输出。
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/your-application/*.log
output.elasticsearch:
hosts: ["localhost:9200"]
index: "your-index-name-%{+yyyy.MM.dd}"
确保Filebeat服务已经启动并运行。
sudo systemctl start filebeat
sudo systemctl enable filebeat
通过以上步骤,你可以在CentOS上使用Filebeat结合Elasticsearch的Watcher来实现日志报警功能。
