aws多いな、linux command結果やSymantecのウィルス対策ソフトのログもあって、botsv2とはかなり違うかも

30ホスト。ざっとみてみると2018-08-202018-08-21に集まっていて、8月いっぱいのログがあったり、2019-09-20のログがポツンとある。

ホスト毎のソースタイプ一覧
| tstats count where index=botsv3 by sourcetype host
| xyseries host sourcetype count
| rename host as _host
| foreach * [ eval sourcetypes = mvappend(sourcetypes,"<<FIELD>>")]
| rename _host as host
| table host sourcetypes
| transpose 0 header_field=host

流石に表を貼り付けられなかったので、クエリーだけ。
awsのログが各ホストに紐づけられている。
AWSか〜勉強しないと

ここまでとします。
