I've not looked at the code, but it +would be *awesome* if this is what was happening :) + +It's very easy to use the journal APIs (either by linking the library, +using python bindings - not sure if there are external perl bindings +yet, but I wouldn't be surprised if there are - or simply calling +journalctl on the command line and parsing the result. It offers an easy +to parse JSON format so even going via this route should be trivial if +official bindings do not exist). You can get all logs between certain +dates and for particular services with ease, without having to look in +the right file or grep for the right binary. i.e. all the building +blocks are in place for you :) + +Col + + +-- + +Colin Guthrie +colin(at)mageia.org +<A HREF="http://colin.guthr.ie/">http://colin.guthr.ie/</A> + +Day Job: + Tribalogic Limited <A HREF="http://www.tribalogic.net/">http://www.tribalogic.net/</A> +Open Source: + Mageia Contributor <A HREF="http://www.mageia.org/">http://www.mageia.org/</A> + PulseAudio Hacker <A HREF="http://www.pulseaudio.org/">http://www.pulseaudio.org/</A> + Trac Hacker <A HREF="http://trac.edgewall.org/">http://trac.edgewall.org/</A> +</PRE> + + + + + + + + + + + + + + + + + + + + + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="019958.html">[Mageia-dev] [soft-commits] [6435] Added a first log viewer module. +</A></li> + <LI>Next message: <A HREF="019954.html">[Mageia-dev] [soft-commits] [6435] Added a first log viewer module. +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#19949">[ date ]</a> + <a href="thread.html#19949">[ thread ]</a> + <a href="subject.html#19949">[ subject ]</a> + <a href="author.html#19949">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-dev">More information about the Mageia-dev +mailing list</a><br> +</body></html> |
