// Hints: |
23 |
// This .d defines compiled in probes |
24 |
// probes are handles (untyped pointers) |
25 |
// v8 forward declared objs (dtrace_connection_t) are defined |
26 |
// in node_dtrace.cc which builds an InitDtrace object which |
27 |
// gets populated with the probes |
28 |
// The probes gather the following: |
29 |
// PROBE_REQUEST(req, fd, remote, port, buffered) |
30 |
// PROBE_OTHER(fd, remote, port, buffered) |
31 |
// other notes: |
32 |
// using any PROBE_ENABLED() macros in dtrace.cc sdt broke it |
33 |
// can only pass strings/ints/primitives not dtrace_connection_t |
34 |
// conn or other structs |
35 |
// verify probe existence by using |
36 |
// $ stap -l 'process("out/Release/node").mark("*")' |
37 |
// TODO: write .stp scripts (node.stp, node_v8ustack.stp + ???) |
