<div dir="ltr">Yep agreed, this is a great idea. <div><br></div><div>We really only need two API calls to get this going:</div><div>- List available logs to ‘save’</div><div>- Save a log (to swift)</div><div><br></div><div>
Some additional points to consider:<br></div><div>- We don’t need to create a record of every Log ‘saved’ in Trove. These entries, treated as a Trove resource aren’t useful, since you don’t actually manipulate that resource.</div>
<div>- Deletes of Logs shouldn’t be part of the Trove API, if the user wants to delete them, just use Swift.</div><div>- A deployer should be able to choose which logs can be ‘saved’ by their users</div></div><div class="gmail_extra">

<div dir="ltr"><div class="gmail_extra"><div class="gmail_quote">I think this is a good idea and I support it. In todays meeting [1] there were some questions, and I encourage them to get brought up here. My only question is in regard to the "tail" of a file we discussed in irc. After talking about it w/ other trovesters, I think it doesnt make sense to tail the log for most datstores. I cant imagine finding anything useful in say, a java, applications last 100 lines (especially if a stack trace was present). But I dont want to derail, so lets try to focus on the "deliver to swift" first option.</div>

Suppose we have an application (binary application, without source code) which requires a DB connection to perform data manipulations and a user would like to perform development, debbuging of an application, also logs would be useful for audit process. Trove itself provides access only for CRUD operations inside of database, so the user cannot access the instance directly and analyze its log files. Therefore, Trove should be able to provide ways to allow a user to download the database log for analysis.</span></p>
