Oh, maybe I misunderstood--- are you talking about seeing many Apache httpd processes or many mod-mono-server processes? > (I don't know it attachments work on this, but I have enclosed a graph > showing how our mod_mono process count just goes up and up until the > server crashes.)

What about the Apache server-status handler? It'll tell you what is being processed (as well as a bit of what was recently processed). There's nothing doing it now in mod_mono. If you really need that and if you're up for it, there are two paths: Store the active request URIs in mod_mono, by revising the shared memory dashboard struct so it has a fixed area to store that information. Store the active request URIs in mod-mono-server and add a command so mod_mono can request the information from mod-mono-server. Doesn't have a fixed limitation on what it can store like the other way, but making the communication work is much harder. > (Which will also allow me to make an XML version of the mod_mono Control > Panel for easier reading of the displayed metrics in 2.0.1...) Can you just make the control panel xHTML and perhaps add some additional tags and attributes?
