Subject: [Erp5-dev] Sentry and Zope
Message-ID: <504E57F2.8090706@nexedi.com>

Hi,

Sentry is a "cloud service" that allows you to post messages and 
tracebacks to a central service. It's Open Source, so you can host your 
own Sentry server:

https://www.getsentry.com/welcome/

Enfold developed an "error_log" replacement for Zope that pushes 
exceptions assynchronously to Sentry. It's here:

http://dist.enfoldsystems.com/catalog/enfold.getsentrylog/releases/1.2/enfold.getsentrylog-1.2.tar.gz

Enfold plans to push the code to a repository somewhere eventually, but 
it's Open Source right now.

I think this would be wonderful for clusters, specially large ones, so 
you don't have to log into individual Zope nodes to look at an 
exception. And it stores a lot more info than just line numbers, ex: 
local variables.

Configuration for Zope clients require only a single environment variable.

I think ERP5 cluster configurations from SlapOS for production 
deployment should (optionallly) provide installation of a Sentry server 
and configuration of Zope clients to access this server.

Cheers,

Leo

Still on the subject of useful products that perhaps we should ship by 
default, there's collective.stats:

http://plone.org/products/collective.stats

It logs awesome statistics, specially ZODB based ones, for each request, 
including how many objects were woken, loaded from cache, or modified by 
that request.

Cheers,

Leo
