|
-ME, --module-exclude Regex for excluding modules/files/libraries
|
|
|
|
[RUNTIME OPTIONS]
|
|
|
|
--label [ args | file | line | return ]
|
|
Labeling info for functions. By default, just the function name is recorded. Use these
|
|
options to gain more information about the function signature or location of the
|
|
functions
|
|
-d, --default-components Default components to instrument (only useful when timemory is enabled in omnitrace
|
|
library)
|
|
--env Environment variables to add to the runtime in form VARIABLE=VALUE. E.g. use '--env
|
|
OMNITRACE_USE_TIMEMORY=ON' to default to using timemory instead of perfetto
|
|
--mpi Enable MPI support (requires omnitrace built w/ MPI and GOTCHA support). NOTE: this will
|
|
automatically be activated if MPI_Init/MPI_Init_thread and MPI_Finalize are found in the
|
|
symbol table of target
|
|
|
|
[GRANULARITY OPTIONS]
|
|
|
|
-l, --instrument-loops Instrument at the loop level
|
|
-r, --min-address-range If the address range of a function is less than this value, exclude it from
|
|
instrumentation
|
|
--min-address-range-loop If the address range of a function containing a loop is less than this value, exclude it
|
|
from instrumentation
|
|
--dynamic-callsites Force instrumentation if a function has dynamic callsites (e.g. function pointers)
|
|
--traps Instrument points which require using a trap. On the x86 architecture, because
|
|
instructions are of variable size, the instruction at a point may be too small for
|
|
Dyninst to replace it with the normal code sequence used to call instrumentation. Also,
|
|
when instrumentation is placed at points other than subroutine entry, exit, or call
|
|
points, traps may be used to ensure the instrumentation fits. In this case, Dyninst
|
|
replaces the instruction with a single-byte instruction that generates a trap.
|
|
--loop-traps Instrument points within a loop which require using a trap (only relevant when
|
|
--instrument-loops is enabled).
|
|
--allow-overlapping Allow dyninst to instrument either multiple functions which overlap (share part of same
|
|
function body) or single functions with multiple entry points. For more info, see Section
|
|
2 of the DyninstAPI documentation.
|
|
|
|
[DYNINST OPTIONS]
|
|
|
|
-b, --batch-size Dyninst supports batch insertion of multiple points during runtime instrumentation. If
|
|
one large batch insertion fails, this value will be used to create smaller batches.
|
|
Larger batches generally decrease the instrumentation time
|
|
--dyninst-options [ BaseTrampDeletion | DebugParsing | DelayedParsing | InstrStackFrames | MergeTramp | SaveFPR | TrampRecursive | TypeChecking ]
|
|
Advanced dyninst options: BPatch::set<OPTION>(bool), e.g. bpatch->setTrampRecursive(true)
|
|
```
|
|
|
|
There are three ways to perform instrumentation:
|
|
|
|
1. Running the application via the omnitrace executable (analagous to `gdb --args <program> <args>`)
|
|
- This mode is the default if neither the `-p` nor `-o` comand-line options are used
|
|
- Runtime instrumentation supports instrumenting not only the target executable but also the
|
|
the shared libraries loaded by the target executable. Consequently, this mode consumes more memory,
|
|
takes longer to perform the instrumentation, and tends to have a more significant overhead on the
|
|
runtime of the application
|
|
- This mode is recommended if you want to analyze not only the performance of your executable and/or
|
|
libraries but also the performance of the library dependencies
|
|
2. Attaching to a process that is currently running (analagous to `gdb -p <PID>`)
|
|
- This mode is activate via `-p <PID>`
|
|
- Same caveats as 1. with respect to memory and overhead
|
|
3. Generating a new executable or library with the instrumentation built-in (binary rewrite)
|
|
- This mode is activated via the `-o <output-file>` option
|
|
- Binary rewriting is limited to the text section of the target executable or library: it will not instrument
|
|
the dynamically-linked libraries. Consequently, this mode performs the instrumentation significantly faster
|
|
and has a much lower overhead when running the instrumentated executable and/or libraries
|
|
- Binary rewriting is the recommended mode when the target executable uses process-level parallelism (e.g. MPI)
|
|
- If your target executable has a minimal main which and the bulk of your application is in one specific dynamic library,
|
|
see [Binary Rewriting a Library](#binary-rewriting-a-library) for help

> ***Attaching to a running process is an alpha feature and support for detaching from the target process***
|
|
> ***without ending the target process is not currently supported.***
|
|
|
|
The general syntax for separating omnitrace command line arguments from the application arguments follows the
|
|
is consistent with the LLVM style of using a standalone double-hyphen (`--`). All arguments preceding the double-hyphen
|
|
are interpreted as belonging to omnitrace and all arguments following the double-hyphen are interpreted as the
|
|
application and it's arguments. In binary rewrite mode, all application arguments after the first argument
|
|
are ignored, i.e. `./omnitrace -o ls.inst -- ls -l` interprets `ls` as the target to instrument (ignores the `-l` argument)
|
|
and generates a `ls.inst` executable that you can subsequently run `ls.inst -l` with.
|
|
|
|
## Runtime Instrumentation
|
|
|
|
```shell
|
|
omnitrace <omnitrace-options> -- <exe> [<exe-options>...]
|
|
```
|
|
|
|
## Attaching to Running Process
|
|
|
|
```shell
|
|
omnitrace <omnitrace-options> -p <PID> -- <exe-name>
|
|
```
|
|
|
|
## Binary Rewrite
|
|
|
|
```shell
|
|
omnitrace <omnitrace-options> -o <name-of-new-exe-or-library> -- <exe-or-library>
|
|
```
|
|
|
|
### Binary Rewriting a Library
|
|
|
|
Many applications bundle the bulk of their functionality into one or more dynamic libraries and have a relatively simple main
|
|
which links to these libraries and simply serves as the "driver" for setting up the workflow. If you binary rewrite your
|
|
executable and find there is insufficient info because of this, you can either switch to runtime instrumentation or
|
|
binary rewrite the libraries of interest.
|
|
|
|
Support for standalone binary rewriting of a dynamic library without binary rewriting the executable is a beta feature.
|
|
In general, it is supported as long as the library contains the `_init` and `_fini` symbols but these symbols are not
|
|
standardized to the extent of `main` in an executable.
|
|
The recommended workflow is as follows:
|
|
|
|
1. Determine the names of the dynamically linked libraries of interest via `ldd`
|
|
2. Generate a binary rewrite of the executable
|
|
3. Generate a binary rewrite of the desired libraries with the same base name as the original library, e.g. `libfoo.so.2` instead of `libfoo.so`
|
|
- Output the instrumented library into a different folder than the original library
|
|
4. Prefix the `LD_LIBRARY_PATH` executable with the output folder from 3
|
|
5. Verify via `ldd` that the instrumented executable resolves the location of the instrumented library
|
|
|
|
### Binary Rewriting a Library Example
|
|
|
|
`foo` executable is dynamically linked to `libfoo.so.2`:
|
|
|
|
```shell
|
|
$ pwd
|
|
/home/user
|
|
$ which foo
|
|
/usr/local/bin/foo
|
|
$ ldd /usr/local/bin/foo
|
|
...
|
|
libfoo.so.2 => /usr/local/lib/libfoo.so.2 (...)
|
|
...
|
|
```
|
|
|
|
Generate binary rewrites of `foo` and `libfoo.so.2`:
|
|
|
|
```shell
|
|
omnitrace -o ./foo.inst -- foo
|
|
omnitrace -o ./libfoo.so.2 -- /usr/local/lib/libfoo.so.2
|
|
```
|
|
|
|
At this point, the instrumented `foo.inst` executable will still dynamically load the original `libfoo.so.2` in `/usr/local/lib`:
|
|
|
|
```shell
|
|
$ ldd ./foo.inst
|
|
...
|
|
libfoo.so.2 => /usr/local/lib/libfoo.so.2 (...)
|
|
...
|
|
```
|
|
|
|
Prefix the `LD_LIBRARY_PATH` environment variable with the folder containing the instrumented `libfoo.so.2`:
|
|
|
|
```shell
|
|
export LD_LIBRARY_PATH=/home/user:${LD_LIBRARY_PATH}
|
|
```
|
|
|
|
When `foo.inst` is executed, it will now load the instrumented library:
|
|
|
|
```shell
|
|
$ ldd ./foo.inst
|
|
...
|
|
libfoo.so.2 => /home/user/libfoo.so.2 (...)
|
|
...
|
|
```
|
|
|
|
## Selective Instrumentation
|
|
|
|
The default behavior of omnitrace does not instrument every symbol in the binary. These default rules are:
|
|
|
|
- Skip instrumenting dynamic call-sites (i.e. function pointers)
|
|
- Option `--dynamic-callsites` will force instrumentation for all dynamic call-sites
|
|
- The cost of a function can be loosely approximated by the size of the function in the binary so by default, omnitrace only instruments functions which span an address range of 256 bytes.
|
|
- Option `--min-address-range` will modify this heuristic for all functions which do not contain loops
|
|
- Option `--min-address-range-loop` will modify this heuristic for functions which contain loops
|
|
- This separate loop option is provided because functions with loops can be compact in the binary while also being costly
|
|
- Skip instrumentation points which require using a trap
|
|
- See the description for the `--traps` and `--loop-traps` options for more information
|
|
- Skip instrumenting loops within the body of a function
|
|
- Option `--instrument-loops` will enable this behavior
|
|
- Skip instrumenting functions with overlapping function bodies and single functions with multiple entry point
|
|
- These arise from various optimizations and instrumenting these functions can be enabled via the `--allow-overlapping` option
|
|
|
|
### Viewing the Available, Instrumented, Excluded, and Overlapping Functions
|
|
|
|
Whenever omnitrace is executed with a verbosity of zero or higher, it emits files which detail which functions (and which module they were defined in)
|
|
were available for instrumentation, which functions were instrumented, which functions were excluded, and which functions contained overlapping function bodies.
|
|
The default output path of these files will be in a `omnitrace-<NAME>-output` folder where `<NAME>` is the basename of the targeted binary or
|
|
(in the case of binary rewrite, the basename of the resulting executable), e.g.
|
|
`omnitrace -- ls` will output it's files to `omnitrace-ls-output` whereas `omnitrace -o ls.inst -- ls` will output to `omnitrace-ls.inst-output`.
|
|
|
|
If you would like to generate these files without executing or generating an executable, use the `--simulate` option:
|
|
|
|
```shell
|
|
omnitrace --simulate -- foo
|
|
omnitrace --simulate -o foo.inst -- foo
|
|
```
|
|
|
|
### Excluding and Including Modules and Functions
|
|
|
|
[Omnitrace](https://github.com/AMDResearch/omnitrace) has a set of 6 command-line options which each accept one or more regular expressions for customizing the scope of which module and/or functions are
|
|
instrumented. Multiple regexes per option are treated as an OR operation, e.g. `--module-include libfoo libbar` is effectively that same as `--module-include 'libfoo|libbar'`.
|
|
|
|
If you would like to force the inclusion of certain modules and/or function without changing any of the heuristics, use the `--module-include` and/or `--function-include` options.
|
|
Note that these options will not exclude modules and/or functions which do not satisfy their regular expression.
|
|
|
|
If you would like to narrow the scope of the instrumentation to a specific set of libraries and/or functions, use the `--module-restrict` and `--function-restrict` options.
|
|
Applying these options allow you to exclusively select the union one or more regular expressions, regardless of whether or not the functions satisfy the
|
|
aforementioned default heuristics. Any function or module that is not within the union of these regular expressions will be excluded from instrumentation.
|
|
|
|
If you would like to avoid instrumenting a set of modules and/or functions, use the `--module-exclude` and `--function-exclude` options.
|
|
These options are always applied regardless of whether the module or function satisfied the "restrict" or "include" regular expression.

## Sampling
|
|
|
|
By default, omnitrace uses `--mode trace` for instrumentation. The `--mode sampling` option
|
|
will only instrument `main` in an executable and will activate both CPU call-stack sampling and
|
|
background system-level thread sampling by default.
|
|
Tracing capabilities which do not rely on instrumentation, such as the HIP API and kernel tracing
|
|
(which is collected via roctracer), will still be available.
|
|
|
|
[Omnitrace](https://github.com/AMDResearch/omnitrace)'s sampling capabilities are always available, even in trace mode, but is deactivated by default.
|
|
In order to activate sampling in trace mode, simply set `OMNITRACE_USE_SAMPLING=ON` in the environment
|
|
or in an omnitrace configuration file.
|
|
|
|
## Embedding a Default Configuration
|
|
|
|
Using the `--env` option, a default configuration can be embedded into the target. Although this option
|
|
works for runtime instrumentation, it is most useful when generating new binaries since the generated
|
|
binary may be used later in a different login sessions when the environment may have changed.
|
|
|
|
For example, if the following sequence of commands are run:
|
|
|
|
```shell
|
|
omnitrace -o ./foo.inst -- ./foo
|
|
export OMNITRACE_USE_SAMPLING=ON
|
|
export OMNITRACE_SAMPLING_FREQ=5
|
|
./foo.inst
|
|
```
|
|
|
|
These configuration settings will not be preserved in another session, whereas:
|
|
|
|
```shell
|
|
omnitrace -o ./foo.samp --env OMNITRACE_USE_SAMPLING=ON OMNITRACE_SAMPLING_FREQ=5 -- ./foo
|
|
```
|
|
|
|
will preserve those environment variables:
|
|
|
|
```shell
|
|
# will sample 5x per second
|
|
./foo.samp
|
|
```
|
|
|
|
while still allowing the subsequent session to override those defaults:
|
|
|
|
```shell
|
|
# will sample 100x per second
|
|
export OMNITRACE_SAMPLING_FREQ=100
|
|
./foo.samp
|
|
```

|
|
### Troubleshooting
|
|
|
|
#### Checking for RPATH
|
|
|
|
If `ldd ./foo.inst` from the [Binary Rewriting a Library Example](#binary-rewriting-a-library-example) section still returned `/usr/local/lib/libfoo.so.2`, your executable may have an rpath encoded in the binary.
|
|
This ELF entry will result in the dynamic linker to ignore `LD_LIBRARY_PATH` if it finds a `libfoo.so.2` in the rpath.
|
|
You can use the `objdump` tool to perform this query:
|
|
|
|
```shell
|
|
objdump -p <exe-or-library> | egrep 'RPATH|RUNPATH'
|
|
```
|
|
|
|
If this produces output, e.g.:
|
|
|
|
```shell
|
|
RUNPATH $ORIGIN:$ORIGIN/../lib
|
|
```
|
|
|
|
You will have to remove or modify the rpath in order to get `foo.inst` to resolve to the instrumented `libfoo.so.2`
|
