接上一篇,我们继续解释如何把ELK跟钉钉及发送邮件功能结合起来,让我们及时的了解重要日志并快速反馈。
- Sentinel 安装,项目介绍在https://github.com/sirensolutions/sentinl,点击可以详细介绍。
运行命令转到kibana的bin目录
cd /usr/share/kibana/bin
,这里是默认安装路径,然后执行如下命令
./kibana-plugin install https://github.com/sirensolutions/sentinl/releases/download/tag-6.3.2-beta-1/sentinl-v6.3.1.zip
,这里根据服务器性能及网络环境,可能要等一会才能看到成功的信息,成功后会自动刷新kibana服务,再次打开kibana,如图所示说明安装成功
- 邮件通知
a) 要发送邮件,得先有一台SMTP发送服务,我这里用的是163,现在几乎提供邮件功能的服务商都可以启动SMTP功能,开通即可。
b) 邮件配置,打开/etc/kibana/kibana.yml 文件,添加如下设置
sentinl:
settings:
email:
active: true
user: lznboy-123@163.com
password: 123456
host: smtp.163.com
ssl: false #根据实际情况添加
report:
active: true
千万注意设置级别,不然会出现莫名的错误。
c) 点击sentinl,添加一个Watcher,我这里配置信息如下。
{ "actions": { "Alerm": { "throttle_period": "1h0m0s", "email": { "to": "lznboy-123@163.com", "from": "lznboy-123@163.com", "subject": "业务系统告警", "priority": "high", "html": "系统程序错误告警: 一共发生{{payload.hits.total}} 次,请登录核查<a herf="http://192.168.1.215:5601" target="_blank">点击登录</a>" } } }, "input": { "search": { "request": { "index": [ "nlog*" ], "body": { "query": { "bool": { "must": [ { "query_string": { "analyze_wildcard": true, "query": ""error"" } }, { "range": { "@timestamp": { "gte": "now-1h", "lte": "now", "format": "epoch_millis" } } } ], "must_not": [] } } } } } }, "condition": { "script": { "script": "payload.hits.total >= 5" } }, "trigger": { "schedule": { "later": "every 2 minutes" } }, "disable": true, "report": false, "title": "nlog", "wizard": {}, "save_payload": false, "spy": false, "impersonate": false }
主要是配置接收者邮箱,判断依据,判断条件,触发间隔
d) 开启Watcher并执行,如下图所示。
等一会,就会在alarms下看到告警信息。
打开配置文件中接收者的邮件,可以看到收到的信息,我的信息如下
,说明邮件告警功能运行正常。
2. 钉钉消息
a) 钉钉接收消息,主要是利用钉钉的机器人功能,首先开通机器人,我的机器人设置如下
主要是利用webhook,接下来在设置发送消息中用到。
b) 钉钉Watcher设置,设置如下
{ "actions": { "Webhook_683bd385-86b3-46ba-8e1b-f89cccccbbec": { "name": "WatcherName", "throttle_period": "1m", "webhook": { "priority": "high", "stateless": false, "method": "POST", "host": "oapi.dingtalk.com", "port": "443", "path": "/robot/send?access_token=ec5fe24b4a218f71bca667975850cbf3f2830b9bd2bd91f60ca07fab28a3d439", "body": " {"msgtype": "text", "text": { "content":"业务系统告警" } }", "params": { "watcher": "{{watcher.title}}", "payload_count": "{{payload.hits.total}}" }, "headers": { "Content-Type": "application/json" }, "auth": "钉钉账号名:密码", "message": "业务功能告警", "use_https": true } } }, "input": { "search": { "request": { "index": [ "nlog*" ], "body": { "query": { "bool": { "filter": { "range": { "@timestamp": { "gte": "now-15m/m", "lte": "now/m", "format": "epoch_millis" } } } } }, "size": 0, "aggs": { "dateAgg": { "date_histogram": { "field": "@timestamp", "time_zone": "Europe/Amsterdam", "interval": "1m", "min_doc_count": 1 } } } } } } }, "condition": { "script": { "script": "payload.aggregations.dateAgg.buckets.some(b => b.doc_count>=5)" } }, "trigger": { "schedule": { "later": "every 1 minutes" } }, "disable": true, "report": false, "title": "nlog_dingding", "wizard": {}, "save_payload": false, "spy": false, "impersonate": false }
c) 开启并执行Watcher,注意观察钉钉,如果收到如下信息,则说明该功能运行成功。
这样,ELK跟业务系统对接,及邮件、钉钉告警已经介绍完了,其实发挥想想并根据业务需求,可以延伸出更有用的功能。如果更好的建议欢迎交流并共同进步。
