So, if you wrote your monitoring client using HTTP now, you would likely have an smaller upgrade path to take advantage of these services later.

The performance differences between XCC and HTTP are small in most cases. I wouldn't assume HTTP is slow for MarkLogic - that's how many customers deploy their applications. I don't understand the use of Zorba in your approach, but maybe I'm overlooking something - it would be interesting to hear what you were thinking. I would think about what you are building as a set of services that can be invoked from your monitoring client. Each service can take different arguments, and each service can emit results in the format you feel is best for your needs (HTML, XML, JSON, etc). Each service would be written as an XQuery program that runs from within the database, like a stored procedure in a relational database (we call them stored modules). This approach allows the database to pre-parse and cache the program for optimal performance. As an aside, stored procedures never felt very natural to me in SQL, but in XQuery whole programs that are invoked as a service feel second nature almost as the language lends itself to this model very nicely. Once you have these services built, you can invoke them from any language that can call out over HTTP. You can use PerformanceMeters to test the performance of your modules. You can even compare between XCC and HTTP if you'd like.

The approach I've chosen to take, at the moment, is to compose xqueries with php and zorba, query the marklogic servers remotely and then proxy the responses into our network monitoring platform. The piece that I'm not entirely sure about is the remote querying of marklogic. Can anyone tell me if, and how, XCC can be used with php? Otherwise, I assume I'll need to use xdbc (I have an xdbc module for php). If anyone can provide advice/guidance, code samples or snippets that will offer greater insight into the solution I need I'll be very grateful. _______________________________________________ General mailing list [email protected] http://developer.marklogic.com/mailman/listinfo/general _______________________________________________ General mailing list [email protected] http://developer.marklogic.com/mailman/listinfo/general
