Questions tagged [salt-stack]

The Salt Project, previously known as SaltStack, is a Python-based open-source configuration management software and remote execution engine.

Salt is an open source tool to manage your infrastructure. Easy enough to get running in minutes and fast enough to manage tens of thousands of servers and still get a response back in seconds.

Execute arbitrary shell commands or choose from dozens of pre-built modules of common (or complex) commands. Target individual servers or groups of servers based on name, defined roles, or a variety of system information such as hardware, software, operating system, current version, current environment, and many more.

Bring your servers up to a known configured state by writing simple lists of items and defining attributes on those lists.

Running an initial install takes about 20 minutes, running a salt-call state.highstate takes about 6 minutes. That's not unreasonable, but I'd like to speed it up, but I'm not sure how to find the slowest states. Is there any way to find how long…
