Adding local logcheck rules to wview to reduce chattiness on server instalation

Wview daily weather view live example
Wview running on my station in Fountain Hills, AZ
I recently installed wview (version 5.20.2) to monitor my Davis Vantage VUE weather station (weather station unboxing and hardware review). This station runs on a 24/7 headless 10.04 Ubuntu LTS server in my basement.

I've finished getting it set up and running. I really like the software. The only thing I haven't seen addressed is the verbosity of the logging. Wview has great capabilities to enable a disable logging from the GUI (see online manual http://www.wviewweather.com/release-notes/wview-User-Manual.html#Configuration-wviewmgmt-services). I found this invaluable when originally setting up my Ubuntu system, but have turned all the configurable logging off.

I'm currently getting a few to many logcheck alerts each day from the server. I run logcheck at the "server" level (sudo nano /etc/logcheck/logcheck.conf configuration line set to REPORTLEVEL="server") to keep track of anything out of the ordinary on the server.


I'm currently getting emails from logcheck with entries like this throughout the day:

Though they are helpful in /var/log/syslog (or /var/log/wview.log entries via rsyslog), they are nothing that I want to see on a consistent basis.I can always pull them from either the /var/log/syslog or /var/log/wview.log when I need them.

I created a local-rules file for logcheck on the server and named it so it would be read when running the server configuration and by starting with local, wouldn't be overwritten in the future by another rule. The following commands create the empty file as root, change file permissions, and open the empty file up in the nano editor.
sudo touch /etc/logcheck/ignore.d.server/local-rules
sudo chmod 640 /etc/logcheck/ignore.d.server/local-rules
sudo nano /etc/logcheck/ignore.d.server/local-rules
and added in these rules to eliminate the the types of messages from being picked up by logcheck:
# Ignoring wview time, NOAA, and compute update messages
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ wviewd\[[0-9]+\]: <[0-9]+> : station time|GMT offset synchronized to: [- :0-9hoursminutes]+

^\w{3} [ :0-9]{11} [._[:alnum:]-]+ htmlgend\[[0-9]+\]: <[0-9]+> : NOAA Generate: updating monthly|yearly NOAA report for [0-9]+
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ htmlgend\[[0-9]+\]: <[0-9]+> : NOAA DB: syncing|done: [0-9]+ HILOW records =>|=> [0-9]+$| NOAA records
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ htmlgend\[[0-9]+\]: <[0-9]+> : NOAA: [0-9]+ days,|months, [0-9]+ months|years

^\w{3} [ :0-9]{11} [._[:alnum:]-]+ wviewd\[[0-9]+\]: <[0-9]+> : computeDataWeek: [0-9]+

I tried to be very specific in the rules so that a message that I did want to see wasn't accidently eliminated.You can easily verify that the messages are being excluded from the logcheck runs by running one or both the commands in the terminal on the server:
sudo egrep -f /etc/logcheck/ignore.d.server/local-rules /var/log/syslog
sudo egrep -f /etc/logcheck/ignore.d.server/local-rules /var/log/wview.log
The lines that would be returned are the lines that you new local-rules would now eliminate.

Moen 1225 Kitchen Faucet Cartridge Repair or Replacement

Image
Is your your Moen single handle kitchen faucet hard to use or leaking around the handle? If it is you can easily lubricate or replace the 1225 cartridge in the faucet. If you're the original owner owner of the faucet Moen warrants them to be leak-free for lifetime. I called the 800 number at 1-800-289-6636 and requested a replacement cartridge kit for the faucet (think ours is model 7730). They sent it out no charge in about 10 days. If your in a hurry you can also buy it from Amazon ( Moen 1225 One-Handle Replacement Cartridge ). Our Moen 7730 Single Handle Kitchen Faucet I shot a video of the dis-assembly and re-assembly of the kitchen faucet: The kit contained everything you need to replace the cartridge and get the faucet working like new again 1225 Cartridge Repair Kit 1225 Cartridge Kit Contents Here is a link to a pdf with the Moen 1225 cartridge installation instructions that came in the kit: Here are the components in the kit: Moen 122...

Outdoor Temperature - Waiting for Update Honeywell WiFI Thermostat (RTH9580WF)

Image
Just bought my wife a new thermostat for our house. We missed the HAI home automation thermostats in our previous house and their ability to display outdoor temperature. The NEST removed too much of our ability to control our thermostat and didn't show outdoor weather conditions. We choose the Honeywell RTH9580WF  (from Amazon) for a few reasons: RTH9580WF Outdoor Temperature - shows waiting for update Pros: Ability to control from a remotely Easy WiFi connectivity Reliable thermostat company Good 4 star plus reviews from Amazon Ability to show outdoor temperature and humidity Easy to use touchscreen and nice design Cons: C wire required No external temperature sensor Replacing  our existing heat pump thermostat was uneventful. I just carefully followed the instructions from Honeywell on how to install it. Our system was new enough to have a C-wire run but not connected to the existing thermostat. Honeywell's online tools and video helped me through this ...

Comcast Xfinity HD uDTA Pace DC60Xu Unboxing and Setup Instructions

Image
Today I picked up two Comcast Xfinity uDTA (HD Digital Transport Adapters). These are the latest DTA's from Comcast that allow you to view HDTV using a tiny cable box as opposed to the huge boxes. They also have the advantage of being much less expensive to rent than the settop boxes. In my area they are easily exchanged for the for the original Thompson DTA's ( http://blog.trebacz.com/2010/03/comcast-dta-digital-transport-adapter.html ) from a couple years ago. Advantages of Comcast Xfinity HD DTA: Small compact size HDMI output or standard cable TV RF remote option (no line of site needed) Same monthly rental as standard definition DTA's Disadvantages of Xfinity HD uDTA: No menu system (or extremely limited) No on-demand programming No channel favorites Below is the unboxing process and what it took to hook it all up. If you'd rather see a video of the process, I did that also. You can see the video on my YouTube channel at: http://www.yo...
