Fetching data from a isolated remote server

[tzemljak]

Hi all,
we have ServerA( Debian) that serves as Nagios host, and ServerB( CentOS) that should report to ServerA.
ServerB has a working installation of NRPE that reports standard sensor feedback to ServerA.
ServerB should report results from a custom sensor that does a curl query to localhost ( curl localhost/mws/platform/status ).
ServerB's web server is ( for security reasons ) configured so it only accepts queryes from localhost, we cannot expose ServerB to network because component that curl would query isn't just read-only , it can modify the system..

I can write a sensor that would run on ServerB and do the curl query, but i'm not sure how to transmit results to ServerA , ServerA can't query ServerB directly because of above mentioned apache configuration.
Can you suggest me a way to transmit data to ServerA, or enable ServerA to query ServerB directly, without exposing it to rest of internet.
Thank you in advance.

Solved by using NRPE. Thanks.
