CE Doctor — why is no loot spawning on my DayZ server?

The most common cause is a single invalid value in types.xml: a usage or value flag that is not defined in cfglimitsdefinition.xml, or a class name that no longer exists. The Central Economy does not report this — it simply stops restocking. Those are exactly the cases CE Doctor finds. The second most common cause is IdleModeStartup in globals.xml: with it set to 1 and nobody online, the economy stops running.

No. The whole analysis runs in your browser. Only the map data and the list of known class names come from the server. Your files are neither stored nor changed.

It compares your load with the untouched vanilla state of the same map. Factor 1 means as full as the original. Factor 3 means three times as much requested loot per available slot. The higher the factor, the more likely rare items drop out completely because the economy can no longer find free slots.

Modded entries are checked as long as their files sit in the mission folder — including the extra files registered in cfgeconomycore.xml. Class names from mods are unknown to our item database; they are listed as a note, not as an error. The budget calculation currently covers Chernarus, Livonia and Sakhal, because those original map files are available.

No, it goes further. An XML validator checks whether a file is syntactically correct. CE Doctor also checks whether the content can work at all in the interplay of all files — that is the class of error that breaks servers silently.
