You've been running queries on your data collection for a long time, but what if I told you that your system can also be queried in this manner? 4 min read PASKHAS Kopasgat Operators, Indonesian Air Force.If you are interested in learning more about Osquery, check out the official documentation for a deeper dive into Osquery’s underlying architecture and features.

My next article will explain how to schedule Osquery to run queries for you. The ability to return data in machine-readable formats, such as JSON, makes Osquery valuable to existing scripts and tools. This tool enables you to explore and understand a system more effectively. Osquery provides a powerful way to query thousands of data points about a system and return data in a structured format. You can learn about them using the -h flag to display the help page. Osquery supports additional output formats. For example, the previous command to obtain process data can be run directly from the command line and printed as either JSON or a list of vertical-bar separated fields: Osquery provides the ability to run a query directly from a single command, and it can also output the results in a script-friendly format, such as JSON. However, you will likely want to leverage this data in your scripts, which requires a non-interactive way to run queries and support machine-readable output. Using the Osquery shell interactively is perfect for exploring the data Osquery exposes. Osquery supports the different types of SQL joins, allowing for complex queries that can assimilate data from multiple tables.

Download RHEL 9 at no charge through the Red Hat Developer program.The result returns data from both tables: The JOIN clause tells Osquery to combine the data from both tables by matching on the UID column. The selection now specifies the table for each column of data in the form $tableName.$columnName. The example below combines the data from both tables. For example, you may want the username associated with the running process instead of just the UID. It would be useful to join this table with the information in the users table displayed previously. It filters the results to processes not being run with UID 0 and limits the number of returned rows to five. The example below queries the processes table to display the UID and name of processes running on the system. However, you frequently want to combine the information from multiple tables to obtain a more complete picture of your system. Querying individual tables is a great way to return structured data about your system. The WHERE clause matches a value of 0 for the UID. For example, the query below will select the root user's user ID (UID), group ID (GID), username, and shell. Osquery supports SQL clauses, such as the WHERE clause, to narrow query results. You will often need to filter the data returned by your queries. For example, you can query the block devices table to obtain information about the block devices on a Linux system: It allows you to query any of this information using a SQL-based syntax.
The Osquery schema contains information about hundreds of aspects of a system. You can launch the shell using the osqueryi command: ~]# osqueryi Osquery provides an interactive query environment similar to a MySQL shell, which is an excellent place to start learning about Osquery's capabilities.

Red Hat systems can install the RPM using DNF: ~]# dnf install -y Osquery provides official packages for various operating systems on its downloads page. My next article will explain how to schedule queries to collect and process data on a regular cadence and respond to changes in the state of your systems. This article walks you through installing and using Osquery on Linux. Osquery is cross-platform and can run both scheduled and ad-hoc queries. Osquery is an open source project that allows you to obtain information about your system using a SQL query language. However, these approaches are often brittle, difficult to maintain, and require deep knowledge of the proper commands to run or files to examine. Most sysadmins have a collection of scripts, one-liners, and other approaches for collecting essential data about a system.
