Hi folks, I'm pleased to announce the 0.6.0 release of psutil: http://code.google.com/p/psutil/
This is one of the best releases so far as it addresses two important issues: system memory functions management and permission errors occurring on Windows and OSX. === Memory functions === psutil.phymem_usage() and psutil.virtmem_usage() are deprecated. Instead we now have psutil.virtual_memory() and psutil.swap_memory(), which should provide all the necessary pieces to monitor the actual system memory usage, both physical and swap/disk related. The refactoring was modeled after Zabbix, see: http://code.google.com/p/psutil/issues/detail?id=311 http://blog.zabbix.com/when-alexei-isnt-looking/#vm.memory.size http://www.zabbix.com/documentation/2.0/manual/appendix/items/vm.memory.size_params If you don't want to read how and why I did that, the bottom line is: if you want to monitor actual system memory usage in a cross platform fashion use: >>> psutil.virtual_memory().available === No more AccessDenied exceptions when querying processes === On Windows and OSX the Process methods below were always raising AccessDenied for any process owned by another user: OSX - name - get_memory_info() - get_memory_percent() - get_cpu_times() - get_cpu_percent() - get_num_threads() WINDOWS - create_time - get_children() - get_cpu_times() - get_cpu_percent() - get_memory_info() - get_memory_percent() - get_num_handles() - get_io_counters() Especially on OSX this made psutil basically unusable as a limited user, even for determining basic process information such as CPU percent or memory usage. Now this is no longer the case. For further details see: http://code.google.com/p/psutil/issues/detail?id=297 http://code.google.com/p/psutil/issues/detail?id=303 === Other major enhancements === - per-process extended memory stats. - per-process number of voluntary and involuntary context switches. - per-process connections: added UNIX sockets support. - (BSD) Process.get_connections() rewritten in C and no longer requiring lsof. - (OSX) added support for process cwd - psutil.network_io_counters() now provides the number of in/out packets dropped and with errors. - new example scripts: example/meminfo.py example/free.py example/netstat.py example/pmap.py === New features by example === >>> import psutil, os >>> p = psutil.Process(os.getpid()) >>> >>> p.get_num_ctx_switches() amount(voluntary=78, involuntary=19) >>> >>> p.get_ext_memory_info() meminfo(rss=9662464, vms=49192960, shared=3612672, text=2564096, lib=0, data=5754880, dirty=0) >>> >>> p.get_connections(kind='unix') [connection(fd=8, family=1, type=1, local_address='/tmp/unix_socket.sock', remote_address=None, status='')] >>> >>> >>> psutil.virtual_memory() vmem(total=8374149120L, available=2081050624L, percent=75.1, used=8074080256L, free=300068864L, active=3294920704, inactive=1361616896, buffers=529895424L, cached=1251086336) >>> >>> psutil.swap_memory() swap(total=2097147904L, used=296128512L, free=1801019392L, percent=14.1, sin=304193536, sout=677842944) >>> === Compatitility notes === 0.6.0 version does not introduce any backward incompatibility. Nevertheless it introduces some deprecations warnings: - psutil.phymem_usage() is deprecated in favor of psutil.virtual_memory() - psutil.virmem_usage() is deprecated in favor of psutil.swap_memory() - psutil.cached_phymem() is deprecated in favor of psutil.virtual_memory().cached - psutil.phymem_buffers() is deprecated in favor of psutil.virtual_memory().buffers The deprecated functions will be removed in next 1.0.0 version. === Links === * Home page: http://code.google.com/p/psutil * Source tarball: http://psutil.googlecode.com/files/psutil-0.6.0.tar.gz * Api Reference: http://code.google.com/p/psutil/wiki/Documentation Please try out this new release and let me know if you experience any problem by filing issues on the bug tracker.
