h2. Introduction
As with any software product, there is sometimes a need to get assistance in understanding or troubleshooting Couchbase products.
A subscription to our Enterprise License comes with a support contract which gives you direct access to the Couchbase Support team. You can find more information about those options [here|http://www.couchbase.com/products-and-services/couchbase-support].
{note}If you do not yet have an Enterprise License, you will want to direct your questions to either the [forums|http://www.couchbase.org/forums/] or the Couchbase mailing list ([Couchbase|http://groups.google.com/group/couchbase]){note}

To speed up the resolution of your issue, we will need some information to troubleshoot what is going on. The more information you can provide in the questions below the faster we will be able to identify your issue and propose a fix:
* Priority and impact of the issue (P1 and production impacting versus a P2 question)
* What versions of the software are you running - Membase/Couchbase Server, moxi, and client drivers?
* Operating system version, architecture (32-bit or 64-bit) and deployment (physical hardware, Amazon EC2, RightScale, etc.)
* Number of nodes in the cluster, how much physical RAM in each node, and per-node RAM allocated to Couchbase Server
* What steps led to the failure or error?
* Information around whether this is something that has worked successfully in the past and if so what has changed in the environment since the last successful operation?
* Provide us with a current snapshot of logs taken from each node of the system and uploaded to our support system via the instructions below
If your issue is urgent, please make a phone call as well as send an e-mail. The phone call will ensure that an on-call engineer is notified.

Diagnostics/logs will give us further detail around the issue itself and the health of your environment.
