title: About the processes Resource
platform: os
---
# processes
Use the `processes` InSpec audit resource to test properties for programs that are running on the system.
<br>
## Availability
### Installation
This resource is distributed along with InSpec itself. You can use it automatically.
### Version
This resource first became available in v1.0.0 of InSpec.
## Syntax
A `processes` resource block declares the name of the process to be tested, and then declares one (or more) property/value pairs:
describe processes('process_name') do
its('property_name') { should eq ['property_value'] }
end
where
* `processes('process_name')` specifies the name of a process to check. If this is a string, it will be converted to a Regexp. For more specificity, pass a Regexp directly. If left blank, all processes will be returned.
* `property_name` may be used to test user (`its('users')`) and state properties (`its('states')`)
<br>
## Examples
The following examples show how to use this InSpec audit resource.
### Test if the list length for the mysqld process is 1
describe processes('mysqld') do
its('list.length') { should eq 1 }
end
### Test if the process is owned by a specific user
describe processes('init') do
its('users') { should eq ['root'] }
end
describe processes('winlogon') do
its('users') { should cmp "NT AUTHORITY\\SYSTEM" }
end
### Test if a high-priority process is running
describe processes('linux_process') do
its('states') { should eq ['R<'] }
end
describe processes('windows_process') do
its('labels') { should cmp "High" }
end
### Test if a process exists on the system
describe processes('some_process') do
it { should exist }
end
### Test for a process using a specific Regexp
If the process name is too common for a string to uniquely find it,
you may use a regexp. Inclusion of whitespace characters may be
needed.
describe processes(Regexp.new("/usr/local/bin/swap -d")) do
its('list.length') { should eq 1 }
end
### Notes for auditing Windows systems
Sometimes with system properties there isn't a direct comparison between different operating systems.
Most of the `property_name`'s do align between the different OS's.
There are however some exception's, for example, within linux `states` offers multiple properties.
Windows doesn't have direct comparison that is a single property so instead `states` is mapped to the property of `Responding`, This is a boolean true/false flag to help determine if the process is hung.
Below is a mapping table to help you understand what property the unix field maps to the windows `Get-Process` Property
| *unix ps field* | *windows PowerShell Property* |
|:---------------:|:-----------------------------:|
|labels |PriorityClass|
|pids |Id|
|cpus |CPU|
|mem |PM|
|vsz |VirtualMemorySize|
|rss |NPM|
|tty |SessionId|
|states |Responding|
|start |StartTime|
|time |TotalProcessorTime|
|users |UserName|
|commands |Path|

## Matchers
For a full list of available matchers, please visit our [matchers page](https://www.inspec.io/docs/reference/matchers/).
### property_name
The `property_name` matcher tests the named property for the specified value:
its('property_name') { should eq ['property_value'] }
