Hi,
Boomerang seems a nice option, but I am working in a cloud environment and
Boomerang requires javascript to be embedded in every page that needs to be
monitored. The applications are run on the lighttpd servers by the users and
it might seem intrusive to embed javascript into their application
There are multiple levels of looking at performance. Tool I wrote analyzes

Here's another option to consider. Finding the top N of some category is
addressed well using random-sampling of transactions, and a new extension to
sFlow will allow HTTP servers to report transaction samples in a standard
format:

Hi,
Thank you so much. This looks really interesting. I am working on a project
to monitor the performance of lighttpd servers in a cloud environment(for
resource provisioning purposes) . Also, in the blog, I was not clear by the
term "response time". Is it the response time as perceived by the cl
You could use Ganglia but depending on number of unique URLs this may not
be such a great idea. I did something similar at a previous job to
evaluate page response times (aggregated on hourly basis). You can find it

Hi,
I was also thinking of having metrics for counting the number of access of a
particular string, but the problem is I am working with an application which
has many directories (similar to wordpress) and there are a lot of
directories which get different amount of hits by the users and I would l
Ganglia doesn't have a model for aggregating string-valued metrics.
On the other hand, you can get a long way by having your
metrics-gathering modules post a count *per string* (e.g.,
"www.yahoo.com:hits", 15); you'll have a ton, though, so you may want
to use some sort of naming prefix to help or
Hi,
I am using Ganglia for monitoring lighttpd server statistics in a cloud
environment. In my case I would have string metrics such as the pages which
are frequently accessed etc. I understand that if there are many clusters,
then Ganglia aggregates the information at the grid level. This is poss
