DIY Zoning: Data Acquisition

Under Construction, Really

Warning

All the stuff below pertains to old as Moses 0.1p7dev3 release, available here. It can't be recommended - though amazingly stable (people have used it for years), it is very old, and making it work on modern distributions is somewhat difficult.

Current code base is under heavy development, and DZ Blog contains a series of articles regarding build and configuration. When the dust settles, those articles will be sorted out and moved here.

DZ3 Quickstart is the first article in the series.

Installation: Easy Way (RPM)

RPMs relevant to data acquisition (available here) are:

  • dz-common - Java code common for all the modules.
  • dz-dac - the Data ACquisition module.
Note
Be sure to check the list of dependencies you will need to have installed in order to install these RPMs.

The first thing to do after you've installed these RPMs is to run the dz_dac_wizard tool - the DAC configuration wizard. It will create the configuration for the DAC.

When you are done with the configuration, you may run the DAC script: dz_dac.

Note
Currently, you may need to fix a few shell scripts to reflect the proper location of the rrdtool binary - unless you chose to use JRobin, in which case nothing needs to be done.

Configuration Considerations

Please refer to DAC section of the Configuration Guide.

Installation: Hard Way (compiling from source)

Please keep in mind that your feedback is sought, and your requests are honored - you'll have to try really hard to come up with something extraordinary. Therefore, if you have a problem, just tell me about it.

Compilation instructions for the "hard way" will not be provided - if you need them, you're not ready (hint: there's a very detailed INSTALL file in the top directory of the source tree). I've tried really hard to make the build process very, very thorough and reliable. Some of the configure script options are documented below. However, should it fail, like I said above, your questions will be answered and requests will be honored.

Configure time options

The first step in compiling the software is running the ./configure script. You can specify the options on the command line, or create the permanent configuration options file. Two locations for it are recognized: global (in /usr/share/dz/configure-options), and/or local (configure-options file in the project top level directory). Below is an example of a configuration options file: 

--prefix=/opt/vt/dz
--with-1wire-port=/dev/ttyS0
--disable-JRobin
--enable-rrdtool

You can get the full list of options by running 

./configure --help

Some of the options are intended to customize the application to the runtime environment (there are usually sensible defaults for them), and some are intended to provide a configuration.

Note
Due to recent introduction of DAC configuration wizard, some of the configure time options have been dropped or will be dropped.

Next Step

By this time, dz_dac is busy collecting the temperature data for you. Time to see what's there: Visualization.
