since Checkpoint People always works and analyses with files..
that's just not true anymore, now that we use industry databases for configuration storage, data is binary across multiple files and cannot be opened using "less" etc. Instead, you got mgmt_cli
What we still have is logs for Management processes. But those very often contain data that is only valid if you combine it with other indicators. If you find "failed" and "error" and "corrupt" in various /var/log files at Check Point machines, it is most likely a false-positive taken from Check Point engines which you don't use - so when those engines checks if they need to be activated, they get a negative answer and print data which may intimidate non-Check Point-Developers.
When you want to get files for troubleshooting, this is your resource: search the error at Support, Support Requests, Training, Documentation, and Knowledge base for Check Point products and ... and find the relevant SecureKnowledge or CheckMates article.
In addition to self-troubleshooting, you can always open support tickets for problems and this will ensure that we fix its root cause for the benefit of all of our users.
