A higher category result means higher impact. tools/analysis/profile.py to profile the queries by running them for a configured number of rounds and reporting the pre-defined performance category of each. But what sort of impact will this have on the client machines?įor this we can use. "query": "SELECT * FROM processes WHERE on_disk != 1 ",Įach query provides useful information and will run every minute. "query": "SELECT DISTINCT process.name, listening.port, listening.protocol, listening.family, listening.address, process.pid, process.path, process.on_disk, process.parent, process.start_time FROM processes AS process JOIN listening_ports AS listening ON process.pid = listening.pid ", "query": "SELECT * FROM kernel_extensions WHERE name NOT LIKE 'com.apple.%' AND name != '_kernel_' ", "query": "SELECT name, version FROM kernel_extensions ", "query": "SELECT name, path, bundle_version, minimum_system_version, applescript_enabled, bundle_executable FROM apps ", "query": "SELECT service, process FROM alf_services WHERE state != 0 ", Before scheduling a set of queries on your enterprise hosts, it is best practice to measure the expected performance impact. ![]() The script can evaluate table, query, and scheduled query performance on a system. The osquery tooling provides a full-featured profiling script. This guide provides an overview and tutorial for assuring performance of the osquery scheduled queries, as well as performance-centric development practices/enforcements. However, user-formed queries are very powerful, and generate opportunities to ruin the performance guarantees of osquery using ill-formed queries. High-performance visibility capability is a core feature of osquery.
