Personally I like componentization and the ability to turn stuff on+off as well as the ability to add new things. That's why I like .d directories so much (or sites-enabled if you think webservers etc.). The risk I think I'm trying to bring up is there seems to be a natural tension between making weewx infinitely extensible+configurable vs. keeping it 'wee'.My opinion is this particular one's original request violates the 'keep it wee' mindset perhaps, maybe, depending on implementation. It's kinda like crontabs. You violate 'wee' if you just edit the system crontab. You are nice and componentized if you use crontabs (directory) and drop in pieces as components you can easily add/supersede/delete into what happens as an aggregated whole. If logwatch could be made to work that way, seems worth thinking about trying to do when getroundtoit happens. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.

[weewx-user] Re: Customised logwatch
I’m sorry but I don’t understand the confusion here. WeeWX ships with 3 logwatch files; 2 config files and a script. The script is what analyses the WeeWX log and produces the WeeWX logwatch report. The WeeWX installer does not ‘install’ the WeeWX logwatch files, rather the user must install them separately as per the wiki. The suggested approach is to create symlinks (in the relevant logwatch directories) to the supplied files. Of course you can make a copy of the script elsewhere, modify it to suit your needs and then link to that file instead (this is what I do). Problem is if there is a change to the core WeeWX logging, and the WeeWX logwatch script is changed accordingly, then those logwatch script changes will not flow through to the copied/modified script being used. The other approach is to create another separate script, a link for which can be placed in the appropriate logwatch directory. Works fine but you will now have a second logwatch report being produced, it will not be part of the logwatch report produced by the logwatch script shipped with WeeWX. Have never been a sysadmin but I don’t think either approach is appropriate or acceptable. This is very similar to customising some WeeWX function. You can modify the core code on your install and it will certainly work as you want, though you now have an orphan that will likely fail post upgrade. Alternatively, you can create a custom service, driver or whatever, place it in the user directory and call it appropriately from weewx.conf and it will coexist quite happily with WeeWX into the future even across upgrades.

Does weewx install something logwatch-related so that logwatch does something different than before weewx was present ? I'm not aware of that.

because logwatch is updated as weewx is updated if messages are altered - so if weewx provides an updated version the stashed away copy with the customisation becomes unusable basically.

[weewx-user] Re: Customised logwatch
The logwatch script needs to be modularised so that users can easily extend the basic logwatch script functionality to cater for extensions and other customisations the user may have installed. The current top to bottom ‘if..elif..else’ structure does not lend itself to being easily extended in a manner that survives upgrades etc. We are aware of the issue but it will probably take until we find the roundtoit before we get around to it.

There are limitations on how much weewx should touch optional other stuff you can hook it up to. For example, do you run syslog, rsyslog, syslog-ng, or multiples ? At some point the admin has to do the steps to admin their box to get the result 'they' want it to have. The admin gets the last word, but that means sometimes they need to do a little more work too. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.

[weewx-user] Re: Customised logwatch
I think I was confusing logwatch and logcheck; logcheck has directories for various categories of messages including "ignore" of which I make much use, while logwatch has scripts it runs for each service, which means it can do rather more with the messages, but makes it a bit less easily tailored...
