guys- i've been using jmeter (http://jakarta.apache.org/jmeter/) to test gangliad (i ran a test over last night). i think jmeter will serve as a great application for regression testing gangliad. i found that from gangliad was able to serve over 4.5 million HTTP requests (from two unique hosts/three unique threads) in 16 hours without failing or leaking memory. i had jmeter assertions setup to ensure that the data received was valid xhtml strict data. i observed an error rate of 0.04%. one of the host was requesting gzipped data and the other uncompressed xhtml. i think the guts of gangliad are pretty solid now.
i highly recommend jmeter for people out there who want to stress test
HTTP, FTP, LDAP servers, etc. jmeter can even act as a web proxy and
"record" your HTTP requests to be saved as part of a regression suite.
sweet. (of course the apache group makes some good stuff).
valgrind tests of the gangliad internals look good too.
are there any security experts on this list? any advice on good tools
to check code/binaries for security problems? any tools to test for
vulnerabilities.
i want to get the module API settled out pretty soon so that you guys
can jump in and start developing. i want ganglia 3.0.0 to be more of a
community project but i'm also worried that i don't want any wasted
effort on your part (i know we all have limited time to offer). if
however, you want to jump in and contribute.. please don't be shy.
