Since starting to use the metrics I've found that they are mainly intended for use in custom keep-alive strategies, so may not always provide the data we want, but I'm hoping to patch HC4 to provide more useful stats in future.

Because the 3rd party jars rarely change, and at the time this was set up, broadband was not generally available.

Re: nightlies vs release: two files
I'm trying to understand why the nightlies have a _bin.zip and _lib.zip instead of just a single .zip like the official 2.4 release did. I know the _lib.zip contains the third party jars and _bin.zip contains everything else - but why not a single .zip like the official release? -Peter On Thu, Apr 14, 2011 at 9:24 AM, sebb wrote: > On 14 April 2011 14:14, Peter Lynch wrote: > > The nightlies require unzipping two files to make a usable runtime as > > described here http://people.apache.org/builds/jakarta-jmeter/nightly/ . > > > > Is it correct to assume that the a final release will just be one > > distributable? > > Sort of. > > There is a binary dist and a source dist, and each is available as zip > and tar.gz, so there are actually 4 archives (plus hashes and sigs). > > However only one binary is needed to run JMeter. > > Here is the download page: > > http://jakarta.apache.org/site/downloads/downloads_jmeter.cgi > > > -Peter > > > > - > To unsubscribe, e-mail: dev-unsubscr...@jakarta.apache.org > For additional commands, e-mail: dev-h...@jakarta.apache.org > > -- Peter Lynch http://blog.peterlynch.ca

Sort of. There is a binary dist and a source dist, and each is available as zip and tar.gz, so there are actually 4 archives (plus hashes and sigs). However only one binary is needed to run JMeter.

nightlies vs release: two files
The nightlies require unzipping two files to make a usable runtime as described here http://people.apache.org/builds/jakarta-jmeter/nightly/ . Is it correct to assume that the a final release will just be one distributable? -Peter

Turned out that the fix was simple (HTTPCORE-254) - the HC4 code was not always updating the metrics. That part of the code seems to depends on how much data is available, so the behaviour is timing related. I still need to fix the original issue so stats can safely be obtained for responses with no content (e.g. HEAD) (though we have a work-round for JMeter). > Thanks for all the fixes to the other code. - To unsubscribe, e-mail: dev-unsubscr...@jakarta.apache.org For additional commands, e-mail: dev-h...@jakarta.apache.org
