Ansible is an agentless configuration management tool that helps operations teams manage installation, patching, and command execution across a set of servers.
Ansible was started as a Linux only solution, leveraging ssh to provide a management channel to a target server. However, starting at Ansible 1.7, support for Windows hosts was added by using Powershell remoting over WinRM.

A nice feature of the Go language is the ability to build binaries for multiple platforms directly from a single source system. As an example, even from a development Windows 7 32-bit machine, you can build binaries for both 64 bit Linux and Windows 2012 Servers.
Before Go 1.5, you needed a compiler for the target architecture, but now that the entire tool chain is written in Go, building for multiple architectures is easy.
And unlike other languages where additional external libraries need to be copied or downloaded on the target system, Go dependencies are generally statically linked [1,2,3,4] into a single binary which makes portability that much easier.

If the logs you are shipping to Logstash are from a Windows OS, it makes it even more difficult to quickly troubleshoot a grok pattern being sent to the Logstash service.
It can be beneficial to quickly validate your grok patterns directly on the Windows host. Here is an easy way to test a log against a grok pattern:

When working from the Windows command line, you can do a quick test to validate your SMTP connectivity using PowerShell:
c:\> Powershell -executionpolicy bypass
PS c:\> Send-MailMessage –to <TO> –from <FROM> –subject "testing123" –body "this is a test" –smtpserver <SMTPServer> -port 25
And if the mail server is accessed over TLS/SSL with SMTP authentication enabled:
PS c:\> Send-MailMessage –to <TO> –from <FROM> –subject "testing456" –body "this is a secure test" –smtpserver <SMTPServer> -port 587 -UseSsl -Credential (Get-Credential)
This is easier than going down to telnet, which is typically not installed on a modern Windows host: Continue reading “Sending SMTP Mail from Windows Using PowerShell”
