SysinfoDiff

sysinfodiff is a utility to analyze mismatched patches installed on ACI Postilion environments.

What is this and Why was this created?

ACI's Postilion system allows admins to create what is called a sysinfo report which includes, among other things, a list of all postilion software installed on a given environment.

This report includes a list of components, and their relevant patches.

Working for multiple banks with Postilion software installed, keeping track of which patches installed in which environments is tricky and error-prone.

I created this utility sysinfodiff which:

• Scans the sysinfos in multiple environments (dev/UAT/prod) and displays the installed components
• Displays the installed patches for each component
• Lists the missing patches for each environment based on patches installed on the other environments.

Supported OSs

Currently only supports Windows server (tested on Server 2016+)

Next version will be re(written) in C++ for native support in Linux based Postilion systems.

Usage

First compile with Visual Studio (tested on 2022) with .NET 4.7.2

C:\sysinfodiff.exe \path_to_sysinfos

Example

C:\sysinfodiff.exe C:\Development\SysinfoDiff\Sysinfos

Where \path_to_sysinfos is where the sysinfo folders are stored.

├── \
│   ├── DevSysinfo
│   │   ├── SystemInfo.txt
│   ├── UATSysinfo
│   │   ├── SystemInfo.txt
│   ├── ProdSysinfo
│   │   ├── SystemInfo.txt

⚠️ Postilion creates many files in the sysinfo folder, but while you can copy the entire sysinfo folder, we are only looking for the sysinfo.txt file

Output

The output file result.html will be created in the same directory as the \path_to_sysinfos.
