(I would like to clarify that I am French, so there may be some translation error in this thread as well as in the program, and I apologize)
I recently created an application that allows you to read your log files in the most graphic way possible.
First, if you are a player, it allows you to find lost messages in the chat and to cross-reference your screenshots with your playing days. For example, if you ask it to display all the logs for Monday 12 September , then all screenshots from Monday September 12th will be displayed. You can combine it with the search option in the chat to find all the screenshots you have taken on a server.
On the other hand, if you are a server administrator, then the application allows you, from a backup, an FTP or SFTP server to see the inventory of your players, the content of their enderchests, shulkers if they have one, their positions, their life, their respawn point and information on the objects they have (enchantment, quantity, ...), all in the most simplistic way possible to make win time. As a bonus, an inventory backup option has just been added allowing you to make a backup of all the players on your server, which you can view and restore, for example in the event of corruption. Thus, it is quite simple to be able to find cheaters for example by only examining their inventory.
In the most recent version, I just added the translate option, which will allow English speakers to be able to use the application.
(I would like to point out that at the time of this writing, I have just released version v0.10, so new options will appear in the future)
