What is OGrEE ?

OGrEE stands for Offline Graph End to End
Offline : no connection with customer SI : only logs (securely) stored somewhere !
Graph : try to link / draw component / informations and their relationships
End-to-End : depending on informations found in logs, OGrEE is able to :

• make the complete I/O path between a "disk" seen under Linux and the way it is built in the storage array, with internal / external replication and full SAN path.
• list/display all impacted devices in DC when maintenance team ask for a PowerPanel maintenance PowerPanel/PowerFeed/PDU/PSU/Devices)
• Displayed information could be more precise if more useful logs are given.

OGrEE is neither SPLUNK, nor a DCIM (netbox) nor an ELK...

And OGrEE-3D ?

This is the OGrEE 3D client: a 3D front end part of OGrEE, based on Unity game engine.
It will display data from OGrEE using OGrEE-CLI.
You can access to the OGrEE-3D repo here.

OGrEE 3D was firstly designed

• to help "non certified" technicians to replace spare parts in complex IT devices
• to avoid loosing time updating "vision/draw.io" schemas
• to propose a funny-visual-3D representation of a datacenter with the ability to display any kind of information on 3D objects

Here is an example video of an OGrEE usage:
