Version 0.10 of libstatgrab has been released.<br /> |
| 51 |
Download it |
| 52 |

</p> |
| 55 |
<p> |
| 56 |
This release concentrates heavily on standardising the names |
| 57 |
of functions and structures throughout libstatgrab. Although |
| 58 |
this will mean changes for existing programs, in the long run |
| 59 |
we hope it'll make things both clearer and easier. However, |
| 60 |
for those who still need the old functions we have provided |
| 61 |
compatibility wrappers. See the NEWS file for details. |
| 62 |
</p> |
| 63 |
<p> |
| 64 |
The other main change in this release is a new function to |
| 65 |
provide full details on currently running processes. See the |
| 66 |
documentation for sg_get_process_stats for details. Along with |
| 67 |
this there are compare functions for use with qsort for sorting |
| 68 |
process, network, and disk io statistics. We've also introduced |
| 69 |
error reporting functions that allow calling applications to |
| 70 |
see why libstatgrab has returned a failure. See sg_get_error. |
| 71 |
</p> |
| 72 |
<p> |
| 73 |
Finally, we've added support for NetBSD 2.0 and tidied up lots |
| 74 |
of areas of the code. This release does not include the python |
| 75 |
bindings - they're now available as their own project called |
| 76 |
<a href="/pystatgrab/">pystatgrab</a>. |

This release brings new features and new platforms. We've |
| 97 |
added information about network interfaces (duplex, speed, |
| 98 |
etc) along with further statistics such as i/o packets, i/o |
| 99 |
errors, and collisions. Support has also been added for |
| 100 |
OpenBSD and DragonFly BSD. Finally some work has been done |
| 101 |
to reduce the platforms on which libstatgrab needs elevated |
| 102 |
privileges. See the NEWS file for more information. |

</p> |
| 113 |
<p> |
| 114 |
The main focus of this release is adding support for |
| 115 |
Solaris 6. We've also added Python bindings so you can use |
| 116 |
libstatgrab directly from Python (see the extras |
| 117 |
directory). Finally, we've tidied up a few bits of the |
| 118 |
code. |

</p> |

<p> |
| 130 |
This release primarily fixes bugs. On Linux a file |
| 131 |
descriptor leak was fixed. On Solaris some significant |
| 132 |
speed increases were made to the disk mapping code, along |
| 133 |
with some bug fixes for Solaris 7 platforms. Also, the |
| 134 |
library part of libstatgrab (but not the tools) is now |
| 135 |
released under the LGPL instead of the GPL. |

</p> |

<p> |
| 147 |
This release brings support for Linux 2.6 and partial |
| 148 |
support for Cygwin. On Solaris libstatgrab now returns disk |
| 149 |
names using cNtNdNsN names rather than the older sdN names. |
| 150 |
There are also a bunch of fixes and optimisations in |
| 151 |
various places. Finally, a new function has been added to |
| 152 |
make it quicker to drop any elevated privileges libstatgrab |
| 153 |
may require on some operating systems. |

The most significant change in this release is support for |

NetBSD 1.6.x. Parts of the FreeBSD code have been |
| 167 |
optimised, and an initialise function has been added to |
| 168 |
allow programs to drop any extra privileges libstatgrab |
| 169 |
needs. The list of known file systems has been increased, |
| 170 |
and libstatgrab has been tested on even more platforms. |
| 171 |
Finally, saidar has been tweaked to work even if it can't |
| 172 |
get all the statistics. |

<h2> |
| 228 |
<a id="what">What is libstatgrab?</a> |
| 229 |
</h2> |
| 230 |
<p> |
| 231 |
libstatgrab is a library that provides cross platform |
| 232 |
access to statistics about the system on which it's run. |
| 233 |
It's written in C and presents a selection of useful |
| 234 |
interfaces which can be used to access key system |
| 235 |
statistics. The current list of statistics includes CPU |
| 236 |
usage, memory utilisation, disk usage, process counts, |
| 237 |
network traffic, disk I/O, and more. |
| 238 |
</p> |
| 239 |
<p> |
| 240 |
The current list of platforms is Solaris 2.x, Linux |
| 241 |
2.2/2.4/2.6, FreeBSD 4.x/5.x, NetBSD 1.6.x, OpenBSD 3.x, |
| 242 |
DragonFly BSD 1.0, and Cygwin. The aim is to extend this to |
| 243 |
include as many operating systems as possible. |
| 244 |
</p> |
| 245 |
<p> |
| 246 |
The package also includes a couple of useful tools. The |
| 247 |
first, <a href="#screenshot">saidar</a>, provides a |
| 248 |
curses-based interface to viewing the current state of the |
| 249 |
system. The second, statgrab, gives a sysctl-style |
| 250 |
interface to the statistics gathered by libstatgrab. This |
| 251 |
extends the use of libstatgrab to people writing scripts or |
| 252 |
anything else that can't easily make C function calls. |
| 253 |
Included with statgrab is a script to generate an |
| 254 |
<a href="http://www.mrtg.org">MRTG</a> configuration file |
| 255 |
to use statgrab. |
