Hi,

on the slide 4.14 is mentioned that logs are retained for a limted time. I think I understand now why, but it was not mention in the slides or https://github.com/cloudfoundry/loggregator.

    Hello StefanBurger, in slides 4.9 and 4.10 there is a small description of the log subsystem and they refer to https://docs.cloudfoundry.org/loggregator/architecture.html with a more detailed description of Loggregator.

    In slide 6.7 Best Effort Design (Chapter 6 is dedicated to the logs management) you will find a description of the log subsystem design.

    You can also increase the buffer of some of Loggregator component (Doppler -> cf logs --recent ), but you must use an external system like ELK for persisting your logs.

    A quick question after reading your reply: do you know how to increase the Loggregator buffer size?

    Regards,

    You can read this:

    https://docs.cloudfoundry.org/running/managing-cf/logging-config.html

    But I think you have to redeploy Cloud Foundry if you are managing a CF server. I don't know how to do it on Pivotal Cloud Service and similar hosted service.
