SummaryPermanent link for this heading

This article provides a general overview of various logfiles created by Mindbreeze and a simple guide to gather those. Additionally logfiles created in combination with Fabasoft Folio as well as the correlation of different component objects created by Mindbreeze in Fabasoft Folio are described.

Gathering Mindbreeze LogsPermanent link for this heading

When submitting Mindbreeze Logs it is always best to include as much information as possible, thus supplying the entire Mindbreeze log directory.
In case the delivery of the complete log directory is not possible (e.g. due to it's size) we can further differentiate issues and the related logfiles.
Please keep in mind that the Mindbreeze service log directories for specific services (index, client, filter, ...) are further devided into subdirectories, each representing the timespan between service restarts.
In most cases supplying e.g. the latest three subdirectories (information up to three service restarts in the past) for a specific service is sufficient.
