Debugging and Logging
|
|
=======================
|
|
|
|
You may view Ceph log files under ``/var/log/ceph`` (the default location).
|
|
|
|
Ceph is still on the leading edge, so you may encounter situations that require
|
|
using Ceph's debugging and logging. To activate and configure Ceph's debug
|
|
logging, refer to `Ceph Logging and Debugging`_. For additional logging
|
|
settings, refer to the `Logging and Debugging Config Reference`_.
|
|
|
|
.. _Ceph Logging and Debugging: ../../config-cluster/ceph-conf#ceph-logging-and-debugging
|
|
.. _Logging and Debugging Config Reference: ../../config-cluster/log-and-debug-ref
|
|
|
|
You can change the logging settings at runtime so that you don't have to
|
|
stop and restart the cluster. Refer to `Ceph Configuration - Runtime Changes`_
|
|
for additional details.
|
|
|
|
Debugging may also require you to track down memory and threading issues.
|
|
You can run a single daemon, a type of daemon, or the whole cluster with
|
|
Valgrind. You should only use Valgrind when developing or debugging Ceph.
|
|
Valgrind is computationally expensive, and will slow down your system otherwise.
|
|
Valgrind messages are logged to ``stderr``.
