概要

osqueryでは、SQLライクなクエリで、コンピューティングノードの情報にアクセスできます。OS X, Ubuntu, CentOS, FreeBSD などのOSで利用できます。

OS ごとに提供されるテーブルが異なるものもありますが、OSに依存せずに情報にアクセスできるのは、魅力の1つです。

osqueryは、OSバージョン、カーネルモジュール、ユーザ情報、グループ、ログインユーザ、パスワードの変更、パッケージやファイル、リスニングポート、NIC、ハードウェアなどの情報を扱うことができます。

ログのディレクトリやファイル

ログファイルは、/var/log/osquery のディレクトリに格納されます。

osqueryd.results.log に json フォーマットでログイングされます。

ログの収集

LogStash や Splunk と連携することもできます。

エラー

osqueryd が起動しない

pid ファイルがあるときに、osqueryd が起動しませんでした。pid ファイルを削除すると動作します。

sudo rm /var/run/osqueryd.pid

osqueryi が起動しない

これは、FreeBSD限定の現象かもしれません。CentOSではrootである必要はありませんでした。

$ osqueryi
E0626 19:42:41.068462 92300288 init.cpp:290] osqueryi initialize failed: Could not create DB handle
Assertion failed: (ret == 0), function ~impl, file src/thrift/concurrency/Mutex.cpp, line 131.

rootユーザでないとエラーが出るようです。

$ sudo osqueryi
osquery - being built, with love, at Facebook
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Using a virtual database. Need help, type '.help'
osquery>

osquery がスタードできない

15.04 だと 14系の osquery は、動かないかもしれない。

$ sudo service osquery start
Job for osqueryd.service failed. See "systemctl status osqueryd.service" and "journalctl -xe" for details.

osqueryi

15.04 だと 14系の osquery は、動かないかもしれない。

osqueryi: error while loading shared libraries: libgcrypt.so.11: cannot open
shared object file: No such file or directory
