[Swift-devel] Re: osg question: how to find sites' health

[Michael Wilde]

Ketan, lets discuss this more tomorrow and report our progress back to the list.

I think "health" is a hard term to define for grid sites. At any given time, each service on each site is either working or not.

- the sites file builder can do various checks
- the checks need to be done under the user's cert to be meaningful
- swift needs to recover from what doesnt get caught by the sites file builder
- clean reporting of errors helps OSG site admins catch and fix problems

I'd like to see Allan's tools merged/extended with a few others, packaged with Swift and documented and tested for Swift users.

Mike
