标签：Set -- 性能 default output php phpspy
phpspy 是基于c 编写的利用了ptrace 的php 性能分析工具，支持apache ,fpm sapi 注意php 主要支持7.0+
参考使用
为了方便，构建了docker 镜像，大家可以直接使用
- 支持的命令
docker run -it dalongrong/phpspy ./phpspy/phpspy --help
Usage:
phpspy [options] -p <pid>
phpspy [options] -P <pgrep-args>
phpspy [options] [--] <cmd>
Options:
-h, --help Show this help
-p, --pid=<pid> Trace PHP process at `pid`
-P, --pgrep=<args> Concurrently trace processes that
match pgrep `args` (see also `-T`)
-T, --threads=<num> Set number of threads to use with `-P`
(default: 16)
-s, --sleep-ns=<ns> Sleep `ns` nanoseconds between traces
(see also `-H`) (default: 10101010)
-H, --rate-hz=<hz> Trace `hz` times per second
(see also `-s`) (default: 99)
-V, --php-version=<ver> Set PHP version
(default: auto;
supported: 70 71 72 73 74 80)
-l, --limit=<num> Limit total number of traces to capture
(approximate limit in pgrep mode)
(default: 0; 0=unlimited)
-i, --time-limit-ms=<ms> Stop tracing after `ms` milliseconds
(second granularity in pgrep mode)
(default: 0; 0=unlimited)
-n, --max-depth=<max> Set max stack trace depth
(default: -1; -1=unlimited)
-r, --request-info=<opts> Set request info parts to capture
(q=query c=cookie u=uri p=path
capital=negation)
(default: QCUP; none)
-m, --memory-usage Capture peak and current memory usage
with each trace (requires target PHP
process to have debug symbols)
-o, --output=<path> Write phpspy output to `path`
(default: -; -=stdout)
-O, --child-stdout=<path> Write child stdout to `path`
(default: phpspy.%d.out)
-E, --child-stderr=<path> Write child stderr to `path`
(default: phpspy.%d.err)
-x, --addr-executor-globals=<hex> Set address of executor_globals in hex
(default: 0; 0=find dynamically)
-a, --addr-sapi-globals=<hex> Set address of sapi_globals in hex
(default: 0; 0=find dynamically)
-1, --single-line Output in single-line mode
-b, --buffer-size=<size> Set output buffer size to `size`.
Note: In `-P` mode, setting this
above PIPE_BUF (4096) may lead to
interlaced writes across threads.
(default: 4096)
-f, --filter=<regex> Filter output by POSIX regex
(default: none)
-F, --filter-negate=<regex> Same as `-f` except negated
-d, --verbose-fields=<opts> Set verbose output fields
(p=pid t=timestamp
capital=negation)
(default: PT; none)
-c, --continue-on-error Attempt to continue tracing after
encountering an error
-#, --comment=<any> Ignored; intended for self-documenting
commands
-@, --nothing Ignored
-v, --version Print phpspy version and exit
Experimental options:
-j, --event-handler=<handler> Set event handler (fout, callgrind)
(default: fout)
-S, --pause-process Pause process while reading stacktrace
(unsafe for production!)
-e, --peek-var=<varspec> Peek at the contents of the var located
at `varspec`, which has the format:
<varname>@<path>:<lineno>
<varname>@<path>:<start>-<end>
e.g., xyz@/path/to.php:10-20
-g, --peek-global=<glospec> Peek at the contents of a global var
located at `glospec`, which has
the format: <global>.<key>
where <global> is one of:
post|get|cookie|server|files|globals
e.g., server.REQUEST_TIME
-t, --top Show dynamic top-like output
- 参考运行命令
docker run -it --cap-add SYS_PTRACE dalongrong/phpspy ./phpspy/phpspy -V73 -r -- php -r 'sleep(1);'
效果
说明
类似的工具xdebug 以及php-profiler也是不错的选择,docker 镜像dalongrong/phpspy 直接可以使用,后续会写直接集成到容器中的玩法
