Search for information from the sysdiagnose/ system_logs.logarchive

[oleegFor]

We need to analyze specific information from system_logs.logarchive, we need logs related to safari history and information such as wifi, phone numbers and mail, where to find it and for what period is the information collected? The last time I did this, the information was collected in 8 days. That was a few years ago. Can I find this data now? And how detailed will it be in 10 days? 30? 100?
