EDDIE-Tool 0.36 Released
EDDIE-Tool 0.36 has just been released. http://eddie-tool.net/ What is it ? The EDDIE-Tool is an intelligent cross-platform monitoring agent written entirely in Python. It provides system, network and security monitoring features, with an extensive configuration facility for defining customized monitoring and data collection rules. What is new ? This version has been a long time coming, but has been well tested over that time. This version features many enhancements and bugfixes, some of them listed below. A special thanks to Zac Stevens and Mark Taylor for their contributions. * Added support for Spread messaging as an alternative to Elvin. * Implemented a DiskStatistics data collector for Linux. * More command-line options and support for running as daemon. * Added a log action. Use it to append to a log file, log via syslog, or print on the eddie tty. * Variables can be set in directives, which can then be used in rule evaluation. For example, if the directive has maxcpu=30, then the rule can address this as rule='pcpu _maxcpu'. * HTTP checks support cookie persistence. * Added DBI directive, for database query checking. * Added Solaris SMF method/manifest files to contrib. * Many more enhancements and bugfixes - see http://dev.eddie-tool.net/trac/browser/eddie/trunk/doc/CHANGES.txt Why is it interesting to Python users ? Besides system and network administrators, Python users may find EDDIE-Tool interesting as it is an example of a threaded, multi-platform software package, providing easy access to system statistics and using Python's power to offer a dynamic and programmable rules engine.

PyObject_Print in gdb
I've been using gdb to debug some Python extension modules lately, which has been very handy, but cannot get PyObject_Print() to work from within gdb, as recommended by http://wingware.com/doc/howtos/debugging-extension-modules-on-linux It recommends using p PyObject_Print (obj, stderr, 0) but stderr (and stdout) symbols are never available for me. (gdb) p args $2 = (PyObject *) 0x405030 (gdb) p PyObject_Print (args, stderr, 0) No symbol stderr in current context. (gdb) p PyObject_Print (args, stdout, 0) No symbol stdout in current context. Any tips on how to reference the stdout/stderr file pointers within gdb? Cheers, Chris -- http://mail.python.org/mailman/listinfo/python-list
Re: PyObject_Print in gdb
I'm still not sure about PyObject_Print, but I found a better solution, using the Misc/gdbinit file from the Python source tree, which defines a pyo macro. Example: (gdb) pyo some_object object : [] type : list refcount: 1 address : 0x4b5940 $3 = void Cheers, Chris On May 15, 2:15 pm, Chris Miles [EMAIL PROTECTED] wrote: I've been using gdb to debug some Python extension modules lately, which has been very handy, but cannot get PyObject_Print() to work from within gdb, as recommended byhttp://wingware.com/doc/howtos/debugging-extension-modules-on-linux It recommends using p PyObject_Print (obj, stderr, 0) but stderr (and stdout) symbols are never available for me. -- http://mail.python.org/mailman/listinfo/python-list

Re: Python speed on Solaris 10
Since my post I have compiled Python 2.4.3 with Sun Studio 11 with -fast option (on Solaris 10) which has produced the fastest version of Python I've been able to test on this hardware, including the CentOS Linux version (which I'm pleased about). I haven't looked into more optimal gcc build options yet, so that may produce a faster build, but I am probably satisfied with what Sun Studio has given me for now. Cheers, Chris [EMAIL PROTECTED] wrote: I noticed that speed difference, too. After running ./configure, I edited the resulting Makefile to pass -march=athlon-mp to the C compiler. ./configure seems to ignore CFLAGS, for example, so I just edited Makefile to suit my environment. You should set the values appropriate for you system, of course. I've also compiled Python using the Sun Studio compiler. Some tests were faster, some tests were slower. -- http://chrismiles.info/ -- http://mail.python.org/mailman/listinfo/python-list
Python speed on Solaris 10
I have found that the sunfreeware.com build of Python 2.4.3 for Solaris 10 is faster than one I can build myself, on the same system. sunfreeware.com doesn't bother showing the options they used to configure and build the software, so does anyone know what the optimal build options are for Solaris 10 (x86)? Here are some pybench/pystone results, and I include the same comparison of Python2.4.3 running on CentOS 4.3 on the same hardware (which is what prompted me to find a faster Python build in the first place). Python 2.4.3: System pybench Pystone (pystones/s) Sol10 my build 3836.00 ms 37313.4 Sol10 sunfreeware3235.00 ms 43859.6 CentOS 3569.00 ms 44247.8 My build: Python 2.4.3 (#1, Oct 15 2006, 16:00:33) [GCC 3.4.3 (csl-sol210-3_4-branch+sol_rpath)] on sunos5 sunfreeware.com build: Python 2.4.3 (#1, Jul 31 2006, 05:14:51) [GCC 3.4.6] on sunos5 My build on CentOS 4.3: Python 2.4.3 (#1, Jul 19 2006, 17:52:43) [GCC 3.4.5 20051201 (Red Hat 3.4.5-2)] on linux2 is the difference purely gcc minor version? -- http://chrismiles.info/ -- http://mail.python.org/mailman/listinfo/python-list
Re: Cannot force configure/setup.py to pick up location of readline (SFWrline) on Solaris 10
Thanks to those who offered suggestions for this. It appears that building Python 2.4.3 on Solaris 10 with readline (SFWrline package) support is a little long-winded but possible, using the following steps: $ ./configure --prefix=/opt/python-2.4.3 --enable-shared $ vi Modules/Setup.local --- add one line: --- readline readline.c -I/opt/sfw/include -L/opt/sfw/lib -lreadline -ltermcap - $ make ### will fail with ld error: ### Undefined first referenced symbol in file initreadline./libpython2.4.so ld: fatal: Symbol referencing errors. No output written to python collect2: ld returned 1 exit status *** Error code 1 make: Fatal error: Command failed for target `python' ### however, just running make again ends up building fine ... ### $ make $ make install # might need root access (sudo/su) I hope this process can be improved, and if I have time I'll look at why make fails half way but works fine when kicked off a second time. I'd like to get /opt/sfw/ added to the standard lib/include path for Solaris (10 at least) as this is where Sun's open-source packages get installed. Is this just a matter of raising a ticket?

Re: Cannot force configure/setup.py to pick up location of readline (SFWrline) on Solaris 10
Martin v. Löwis wrote: You need to use GNU make for that to work. The build regenerates the makefile, but Sun make doesn't recognize the change. There was a message telling you so. Thanks Martin, you are totally correct. Using gmake avoids the problem. Also, your original complaint wasn't that readline isn't considered, but that setup.py didn't find it even though configure did. A patch fixing that has a higher chance of being accepted than a patch adding /opt/sfw to the standard search path (which is really a decision Sun should take, not the Python maintainers - in absence of a Sun change, it's then the local administrator who decides). Fair point. If time permits I'll look into constructing such a patch. Cheers, Chris -- http://chrismiles.info/ -- http://mail.python.org/mailman/listinfo/python-list
Cannot force configure/setup.py to pick up location of readline (SFWrline) on Solaris 10
On a standard Solaris 10 installation with Sun-supplied open-source packages installed (like SFWrline for readline libs) I cannot seem to force Python configure/setup.py to build with readline support. SFWrline installs readline in /opt/sfw/lib /opt/sfw/include (This is all attempted with Python-2.4.3 on Solaris 10 06/06 i386) With this configure: ./configure --prefix=/opt/python-2.4.3 --enable-shared CPPFLAGS=-I/opt/sfw/include CFLAGS=-I/opt/sfw/include LDFLAGS=-L/opt/sfw/lib The resulting output includes: ... checking for rl_callback_handler_install in -lreadline... yes checking for rl_pre_input_hook in -lreadline... yes checking for rl_completion_matches in -lreadline... yes ... and config.log contains: ... ac_cv_lib_readline_rl_callback_handler_install=yes ac_cv_lib_readline_rl_completion_matches=yes ac_cv_lib_readline_rl_pre_input_hook=yes ... However, make doesn't build a readline module and I think this is because setup.py is not taking the custom *FLAGS into account. Even if I export them as environment variables, I get no readline module. How do I force the build to use the custom paths? And/or: can we teach configure/setup.py to include /opt/sfw/ when on Solaris, as this is the standard location for Sun's supplied open-source packages (ie: on the Companion disc) ? btw: an answer to this is not to install other 3rd party readline packages such as from sunfreeware.com or blastwave, as that should not be necessary when Sun supply the packages themselves (and some organisations will not allow those packages).

Re: heartbeats
Hi Yves, You could try using EDDIE Tool's PORT directive to periodically make TCP connections to your clients and check the result matches what is expected. The alert engine will make it easy for you to define actions to perform for failure conditions. http://eddie-tool.net/ You could also do actual (icmp) pings and/or HTTP requests from it also, if that helps. Cheers, Chris Yves Glodt wrote: I need to write a heartbeat solution to monitor some external clients, and what is different as in the examples that I have seen so far is that I want my central server to poll the clients, and not the clients pinging the central server. In detail I need a daemon on my central server which e.g. which in a loop pings (not really ping but you know what I mean) each 20 seconds one of the clients. -- http://chrismiles.info/ -- http://mail.python.org/mailman/listinfo/python-list
Re: How to ping in Python?
You could also try the ping module that the Eddie monitoring tool has been using successfully, cross-platform, for many years. http://dev.eddie-tool.net/trac/browser/eddie/trunk/lib/common/Directives/pinger.py Cheers, Chris Nico Grubert wrote: I could not find any ping Class or Handler in python (2.3.5) to ping a machine.
