APIs

Vzlogger is able to push the gathered data to different backend systems for further processing or storage. This is done via the `api` parameter that is configured per channel. Vzlogger's default backend api is volkszaehler, which is the volkszaehler middleware. Additonal options are mysmartgrid and a 'null' api.

Configuration

Example configuration is not runable, all the meter are deactivated

The vzlogger configuration is done with a file containing JSON encoded settings. General settings also can be set via the command line. You must have at least one meter in your configuration. Channels are optional. A meter can have more channels. Ex. if you want to log to multiple middleware servers.

All meter protocols have own properties. We do not describe them here in detail. Just take a look at the example configuration. It contains a meter for every protocol.

Example configurations are included in the distribution, see https://github.com/volkszaehler/vzlogger/blob/master/etc/ or in detail here in the wiki: vzlogger_conf_parameter

You can also find different user's configurations in the howto section.

You can also use these script: vzlogger.conf-editor

Meter Identifier Bemerkung
SML, D0 Obis-Codes z.B. 1-0:1.8.0 Welche Obis-Codes/Identifier gesendet werden ist abhängig vom Gerät
OMS Obis-Codes 1.8.0, 2.8.0, 1.7.0, 2.7.0 max. die 4 Obis-Codes, abhängig vom Gerät
S0 „Impulse“ und „Impulse_neg“ Anzahl Impulse (pro Sekunde)
S0 „Power“ und „Power_neg“ Impulse pro Zeiteinheit umgerechnet in „Leistung“ (per Parameter resolution)
1Wire ID des 1-Wire-Sensors Pro gefundenem Sensor ein Identifer mit Temp. als Wert
FluksoV2 2 pro Channel mittels ChannelId und -ChannelId Consumption = -ChannelId, Power = +ChannelId
File, Exec (leer) oder per $i erkannter Identifier z.B. $i = $v ⇒ Temperatur = 10 ⇒ Identifier „Temperatur“, Value = 10
OCR konfigurierbar siehe Config Option „identifier“
Random kein Identifier Name, nur Wert und Zeit

Command line parameters

longshort
--config-c/etc/vzlogger.confconfiguration file
--log-o/var/log/vzlogger/vzlogger.loglog file
--httpd-loffactivate local interface (tiny HTTPd which serves live readings)
--httpd-port-p8081TCP port for HTTPd
--help-h show short help
--verbose-vlevel0enable verbose output (0-15; 0 = log_alert, 1 = log_error, 3 = log-warning, 5 = log_info, 10 = log-debug, 15 = log_finest)
--version-V show version of vzlogger

Exit-Codes

For diagnostics usally the logfile is used because of vzlogger running under control of systemd. In cases this is not possible exit-codes will be shown.
E.g. calling systemctl status vzlogger shows something like: Main process exited, code=exited, status=1/FAILURE

codetextmeaning
1FAILUREgeneric failure, is also generated by unfeasible configuration when vzlogger is closed because of no active meters (example config from git)
64USAGEcli argument is bad
71OSERRmoving service to background (daemon) didn't work out
73CANTCREATvzlogger lacks the rights to write logfile
