+This is an Nginx fork that adds dtrace USDT probes.
-Documentation is available at http://nginx.org
+This is still under development and not usable yet.
+
+Installation:
+
+ ./configure --with-dtrace-probes \
+ --with-dtrace=/usr/sbin/dtrace \
+ ...
+ make
+ make install
+
+Usage on Linux (with systemtap):
+
+ # make the stap-nginx script visiable in your PATH
+ export PATH=/usr/local/nginx/sbin:$PATH
+
+ # list all the static probes available in your nginx
+ stap-nginx -L 'process("nginx").mark("*")'
+
+ # run the test.stp file
+ stap-nginx test.stp
+
+Sample test.stp file:
+
+ probe begin
+ {
+ print("Tracing. Hit CTRL-C to stop.\n")
+ }
+
+ probe process("nginx").mark("http-subrequest-start")
+ {
+ printf("uri: %s?%s\n", ngx_http_req_uri($arg1),
+ ngx_http_req_args($arg1))
+ }
+
+For now, only tested on Solaris 11 Express and Fedora Linux 17.
+
+The original Nginx documentation is available at http://nginx.org
