Re: Infrastructure monitoring

Actually it seems to be as easy as requesting a GET to search.postgresql.org
If a script is able to handle the http codes, then alerts could be triggered
upon events.

The search failure was due to a 503 error being dispatched from the server.

GET http://search.postgresql.org

Am I wrong?

Tho, thinking about content, there is an opensource doing a job such as
siteconf (http://www.siteconfidence.com) but I can't remember the name atm.

But I understand that the search problem was not a *content* problem itself.
