It is possible to install osquery on many OS: Operating Systems supported by OsqueryÄepending on the operating system you are using you can have extra information. In addition, we will extend osquery information by adding a new table in the endpoint. We will use Golang to execute queries programmatically. The communication interface is not limited only to the interpreter. Logs may be forwarded to a centralized logging system. It is useful to make system audits and record events in logs. Then we will figure out the scheduled queries using the osqueryd daemon. After installing it, we will get started to make some queries from a simple to a complex one. ![]() ![]() In this article, we will explore the osquery possibilities.

Tables represent OS abstract concepts such as users or processes for example. Osquery exposes the OS as a high-performance relational database. This is the concept that the osquery project pushes by providing a low-level and powerful endpoint that can be used for system analysis or monitoring The osquery project logo How Does Osquery Work Finally, an operating system can be considered roughly and simplified as a database and the command line as a query to access what we want. The command line allows us to retrieve information about the current state of the system.
