    of any PythonDataSourcePlugin is called The timer is cancelled as soon as that collect method returns If the timer reaches blockingtimeout before the collect method returns the zenpython process completely restarts itself with the plugin that failed to return in time disabled This may sound extreme but for technical reasons was really the only way to recover from being blocked To understand why zenpython must restart itself you have to understand how zenpython is a single threaded process that uses asynchronous IO via the Twisted library to efficiently perform lots of parallel collection Anytime non asynchronous code is being executed it means that no other collection or process can be performed until it yields back to the reactor Twisted s event loop The catch here is that zenpython is executing arbitrary code provided by ZenPacks The zenpython code essentially gives up control to that ZenPack code as soon as it calls it until that code returns The way that zenpython manages to restart itself when it calls to ZenPack code that doesn t return is by running a watchdog thread that keeps an eye on that timer and restarts the process if it expires So another question you d ask and I think you implied is why disable the plugin for 2 devices when it only timed out on 1 device To understand why that is done you have to imagine a scenario where you have a plugin that executes on all Linux servers Let s say you have 1 000 Linux servers being monitored and let s say that 50 of them develop some condition that causes the plugin to block on them for 10 seconds Assuming it takes zenpython only 1 minute to restart when monitoring 1 000 servers it would take 60 seconds 10 seconds 50 servers or 11 minutes before zenpython would have all of the plugin device executions disabled During this time zenpython wouldn t be doing anything So we re forced to assume that if a plugin blocks once that it s not written correctly and using blocking IO So the plugin is completely disabled for all devices that use it So now back to why the default blockingtimeout is set to 5 which may seem way too low given everything above To understand this you again have to understand why the PythonDataSourcePlugin collect method must return a Deferred After all it s easy to imagine making an API call to some application that takes more than 5 seconds When using Twisted s non blocking networking APIs you immediately get a Deferred object returned when you make a call like getPage http example com api really slow thing even if the response doesn t come back for 10 minutes When the response comes back the Deferred s callback or errback if there s an error is called The PythonDataSourcePlugin collect must do the same thing Usually by returning the Deferred object that something like getPage http returned to you If you properly use Twisted
