Subject Re: Review Request: cs-bugtool implementation, new troubleshooting tool dedicated for collecting CS logs and basic system information
Date Wed, 19 Dec 2012 19:19:15 GMT
Chip, how did you get your superpower to discard (I'm guessing submit as well) a review request?
May I have the superpower to close a review request once it has been shipped?

might not be okay with. May be it should be made interactive and warn the user of the actions
it will/has performed. When as a commercial support provider you have permission to access
and troubleshoot a system it would be okay to run this. But IMO it could be provided by that
company which is looking to provide support to the operator of the said cloud to simplify
their process of support. So I'm slightly wary of accepting something like this unless someone
else convinces me that this would absolutely be beneficial. Also admins operating large clouds
might be using a syslog server to already do some (or more) of these actions for them. If
the logs are moved away from where one expects them to be then this script fails.

>>>    1. CloudStack is a project which targets cloud enthusiasts but also "enterprises"
and if you have a look on all the big products, vendors on the marker they offer utilities
which do exactly what cs-bugtool does. Collect logs, basic system and configuration information.
Examples: NetApp autosupport, XenServer xs-bugtool, VMware vSphere Client does this, . . .,
and many others which I don't know. So IMHO CloudStack should also include this type of utility.

share it with other trusted persons or some support representative and this really can speed
up analysis, avoid tens of questions, sending emails and files back and forth.

exactly is collected

>>>     d.) The main use case of this utility is to share output archive with trusted
people or some sort of support representative not to make public users' configurations. We
do not send any information automatically, we just give a user a blob and user decides what
to do with this.

that provide support professionally. That said it can not hurt to have the tool in the main
code, but it might trigger people to make these blobs and send them to the -users mailing
list looking for support. Not sure yet if that is a good thing or not. A lot of deployments
will have slight changes based on the preferences of the administrators, so the script should
handle this gracefully.

or a recent branch (4.0 branch or master branch).

using this for sharing logs, we can go ahead and merge it. I only worry that if this gets
committed now, and not used it would add bloat. I would really want to use this tool if this
could also go to all the hosts and maybe ssvm/cpvm and get me logs, it would be awesome. But,
if the folks don't give this a "ship it" I would want you to show 'em why we would want this
tool with the next iteration of this tool and features.

it is dependent on apis, marvin, so I moved it in.
