针对Dos Events数据,能否快速统计出指定时间段内,某一个destination ip 的top N source ip 信息嘛。
目前在E现场统计2022-09-01~2023-03-16时间段内,Dos Events里Severity=Critical的日志信息,
Top 2 Destination IP分别为:
197.156.74.223:236次
197.156.74.222:166次
搜索指定destination IP的日志,得到的是Source IPs列表,里面甚至有很多是Private IP,如何能快速统计出指定时间段具体某个destination ip 的top N source ip 及出现的总次数。doufenghu commented on 2023-03-30T14:58:25.140+0800:
- 通过SQL查询获取结果
{code:java} select item, sum(count) as count from ( select arrayJoin(items) as item,count from ( select splitByString(',', source_ip_list) as items, count(*) as count from dos_event lt where destination_ip = '27.50.64.2' and notEmpty(source_ip_list) and start_time >= toUnixTimestamp(parseDateTimeBestEffort(toString('2023-03-10 00:00:00+03:00'))) AND start_time < toUnixTimestamp(parseDateTimeBestEffort(toString('2023-03-26 00:00:00+03:00'))) group by source_ip_list ) ) group by item order by count desc limit 10 {code}
- 后续版本支持: ** 方式1: 可在23.04 Source IPs 定义业务逻辑类型为Array,作为多值列统计(基于v23.03业务逻辑类型定义支持) ** 方式2: Report Log Type增加 DoS Events ,增加预置数据集

通过session record搜索server ip为目标IP,然后通过日志字段发现查看top 10的client ip是否能够满足需求?[~liuju]

[~liuyang] 洋姐,你意思是像附件那种截图里的那样搜索嘛,搜索结果现场top 10 的结果是10个集合(source ips)和预期不符,想要的是top N client ip。

根据虎哥提供的查询语句,查询4月份Destination IP为197.156.74.223/222出的top 10 client ip 全是10.x.x.x私网ip,后根据岱杰更新的语句,可以查询4月份Destination IP为197.156.74.223/222排除了私网IP之后的top 10 client ip和count ,目前查询的结果已上传展示在了附件中。
执行的更新后查询语句如下:
1、 clickhouse-client -h 10.224.11.35 --port 9001 -m -u default -d tsg_galaxy_v3 --password ***
2、
select item, sum(count) as count from ( select arrayJoin(items) as item,count from ( select splitByString(',', source_ip_list) as items, count(*)as count from dos_event lt where destination_ip = '27.50.64.2' and notEmpty(source_ip_list) and start_time >= toUnixTimestamp(parseDateTimeBestEffort(toString('2023-03-10 00:00:00+03:00'))) AND start_time < toUnixTimestamp(parseDateTimeBestEffort(toString('2023-03-26 00:00:00+03:00'))) group by source_ip_list ) ) where (item not like('10.%') AND item not like('172.%') AND item not like('192.168.%')) group by item order by count desc limit 10;

[~liuju]直接在 session record中搜索,不是dos event中搜索 !screenshot-1.png|thumbnail!
