DbLog

-
    -
    - - - Define -
      - define <name> DbLog <configfilename> <regexp> -

      - - Log events to a database. The database connection is defined in - <configfilename> (see sample configuration file - contrib/dblog/db.conf). The configuration is stored in a separate file - to avoid storing the password in the main configuration file and to have it - visible in the output of the list command. -

      - - The modules DBI and DBD::<dbtype> - need to be installed (use cpan -i <module> - if your distribution does not have it). -

      - - <regexp> is the same as in FileLog. -

      - Sample code to create a MySQL/PostgreSQL database is in - <DBType>_create.sql. - The database contains two tables: current and - history. The latter contains all events whereas the former only - contains the last event for any given reading and device. - The columns have the following meaning: -
        - -
      1. TIMESTAMP: timestamp of event, e.g. 2007-12-30 21:45:22
        2. -
      2. DEVICE: device name, e.g. Wetterstation
        3. -
      3. TYPE: device type, e.g. KS300
        4. -
      4. EVENT: event specification as full string, - e.g. humidity: 71 (%)
        5. -
      5. READING: name of reading extracted from event, - e.g. humidity
        6. - -
      6. VALUE: actual reading extracted from event, - e.g. 71
        7. -
      7. UNIT: unit extracted from event, e.g. %
        8. -
      - The content of VALUE is optimized for automated post-processing, e.g. - yes is translated to 1 -

      - The current values can be retrieved by the following code like FileLog:
      -
        - get myDbLog - - 2012-11-10 2012-11-10 KS300:temperature:: -
      -

      - Examples: -
        - # log everything to database
        - - define myDbLog DbLog /etc/fhem/db.conf .*:.* -
      -

DbLog

-
    -
    - - - Define -
      - define <name> DbLog <configfilename> <regexp> -

      - - Speichert Events in eine Datenbank. Die Datenbankverbindungsparameter werden - definiert in <configfilename>. (Vergleiche - Beipspielkonfigurationsdatei in contrib/dblog/db.conf).
      - Die Konfiguration ist in einer sparaten Datei abgelegt um das Datenbankpasswort - nicht in Klartext in der FHEM-Haupt-Konfigurationsdatei speichern zu müssen. - Ansonsten wäre es mittels des list - Befehls einfach auslesbar. -

      - - Die Perl-Module DBI and DBD::<dbtype> - müssen installiert werden (use cpan -i <module> - falls die eigene Distribution diese nicht schon mitbringt). -

      - - <regexp> ist identisch wie FileLog. -

      - Ein Beispielcode zum Erstellen einer MySQL/PostGreSQL Datenbak ist in - contrib/dblog/<DBType>_create.sql zu finden. - Die Datenbank beinhaltet 2 Tabellen: current und - history. Die Tabelle current enthält den letzten Stand - pro Device und Reading. In der Tabelle history sind alle - Events historisch gespeichert. - - Die Tabellenspalten haben folgende Bedeutung: -
        -
      1. TIMESTAMP: Zeitpunkt des Events, z.B. 2007-12-30 21:45:22
        2. -
      2. DEVICE: name des Devices, z.B. Wetterstation
        3. -
      3. TYPE: Type des Devices, z.B. KS300
        4. -
      4. EVENT: das auftretende Event als volle Zeichenkette - z.B. humidity: 71 (%)
        5. -
      5. READING: Name des Readings, ermittelt aus dem Event, - z.B. humidity
        6. - -
      6. VALUE: aktueller Wert des Readings, ermittelt aus dem Event, - z.B. 71
        7. -
      7. UNIT: Einheit, ermittelt aus dem Event, z.B. %
        8. -
      - Der Wert des Rreadings ist optimiert für eine automatisierte Nachverarbeitung - z.B. yes ist transformiert nach 1 -

      - Die gespeicherten Werte können mittels GET Funktion angezeigt werden: -
        - get myDbLog - - 2012-11-10 2012-11-10 KS300:temperature -
      -

      - Beispiel: -
        - Speichert alles in der Datenbank
        - - define myDbLog DbLog /etc/fhem/db.conf .*:.* -
      -
    - - - - Set
      N/A

    - - - Get -
      - get <name> <infile> <outfile> <from> - <to> <column_spec> -

      - Ließt Daten aus der Datenbank. Wird durch die Frontends benutzt um Plots - zu generieren ohne selbst auf die Datenank zugreifen zu müssen. -
      - -
        -
      • <in>
        - Ein Dummy Parameter um eine Kompatibilität zum Filelog herzustellen. - Dieser Parameter ist immer auf - zu setzen. -
        • -
      • <out>
        - Ein Dummy Parameter um eine Kompatibilität zum Filelog herzustellen. - Dieser Parameter ist immer auf - zu setzen um die - Ermittlung der Daten aus der Datenbank für die Plotgenerierung zu prüfen.
        - Durchd ie Angabe des Schlüsselworts all werden alle - Spalten der Datenbank ausgegeben. -
        • -
      • <from> / <to>
        - Wird benutzt um den Zeitraum der Daten einzugrenzen. Es ist das folgende - Zeitformat oder ein Teilstring davon zu benutzen:
        -
          YYYY-MM-DD_HH24:MI:SS
        • -
      • <column_spec>
        - Für jede column_spec Gruppe wird ein Datenset zurückgegeben welches - durch einen Kommentar getrennt wird. Dieser Kommentar repräsentiert - die column_spec.
        - Syntax: <device>:<reading>:<default>:<fn>:<regexp>
        -
          -
        • <device>
          - Der Name des Devices. Achtung: Groß/Kleinschreibung beachten!
          • -
        • <reading>
          - Das REading des angegebenen Devices zur Datenselektion. - Achtung: Groß/Kleinschreibung beachten! -
          • -
        • <default>
          - Zur Zeit noch nicht implementiert. -
          • -
        • <fn> - Angabe einer speziellen Funktion: -
            -
          • int
            - Ermittelt den Zahlenwert ab dem Anfang der Zeichenkette aus der - Spalte "VALUE". Benutzt z.B. für Ausprägungen wie 10%. -
            • -
          • int<digit>
            - Ermittelt den Zahlenwert ab dem Anfang der Zeichenkette aus der - Spalte "VALUE", inclusive negativen Vorzeichen und Dezimaltrenner. - Benutzt z.B. für Ausprägungen wie -5.7°C. -
            • -
          • delta-h / delta-d
            - Ermittelt die relative Veränderung eines Zahlenwertes pro Stunde - oder pro Tag. Wird benutzt z.B. für Spalten die einen - hochlaufenden Zähler enthalten wie im Falle für ein KS300 Regenzähler - oder dem 1-wire Modul OWCOUNT. -
            • -
          • -
        • <regexp>
          - Diese Zeichenkette wird als Perl Befehl ausgewertet. $val ist der - aktuelle Wert die die Datenbank für ein Device/Reading ausgibt. - Die regexp wird vor dem angegebenen <fn> Parameter ausgeführt. -
          - Bitte zur Beachtung: Diese Zeichenkette darf keine Leerzeichen - enthalten da diese sonst als <column_spec> Trennung - interpretiert werden und alles nach dem Leerzeichen als neue - <column_spec> gesehen wird. -

DbLog

+
    +
    + + + Define +
      + define <name> DbLog <configfilename> <regexp> +

      + + Log events to a database. The database connection is defined in + <configfilename> (see sample configuration file + contrib/dblog/db.conf). The configuration is stored in a separate file + to avoid storing the password in the main configuration file and to have it + visible in the output of the list command. +

      + + The modules DBI and DBD::<dbtype> + need to be installed (use cpan -i <module> + if your distribution does not have it). +

      + + <regexp> is the same as in FileLog. +

      + Sample code to create a MySQL/PostgreSQL database is in + <DBType>_create.sql. + The database contains two tables: current and + history. The latter contains all events whereas the former only + contains the last event for any given reading and device. + The columns have the following meaning: +
        + +
      1. TIMESTAMP: timestamp of event, e.g. 2007-12-30 21:45:22
        2. +
      2. DEVICE: device name, e.g. Wetterstation
        3. +
      3. TYPE: device type, e.g. KS300

DbLog

+
    +
    + + + Define +
      + define <name> DbLog <configfilename> <regexp> +

      + + Speichert Events in eine Datenbank. Die Datenbankverbindungsparameter werden + definiert in <configfilename>. (Vergleiche + Beipspielkonfigurationsdatei in contrib/dblog/db.conf).
      + Die Konfiguration ist in einer sparaten Datei abgelegt um das Datenbankpasswort + nicht in Klartext in der FHEM-Haupt-Konfigurationsdatei speichern zu müssen. + Ansonsten wäre es mittels des list + Befehls einfach auslesbar. +

      + + Die Perl-Module DBI and DBD::<dbtype> + müssen installiert werden (use cpan -i <module> + falls die eigene Distribution diese nicht schon mitbringt). +

      + + <regexp> ist identisch wie FileLog. +

      + Ein Beispielcode zum Erstellen einer MySQL/PostGreSQL Datenbak ist in + contrib/dblog/<DBType>_create.sql zu finden. + Die Datenbank beinhaltet 2 Tabellen: current und + history. Die Tabelle current enthält den letzten Stand + pro Device und Reading. In der Tabelle history sind alle + Events historisch gespeichert. + + Die Tabellenspalten haben folgende Bedeutung: +
        +
      1. TIMESTAMP: Zeitpunkt des Events, z.B. 2007-12-30 21:45:22
        2. +
      2. DEVICE: name des Devices, z.B. Wetterstation
        3. +
      3. TYPE: Type des Devices, z.B. KS300
        4. +
      4. EVENT: das auftretende Event als volle Zeichenkette + z.B. humidity: 71 (%)
        5. +
      5. READING: Name des Readings, ermittelt aus dem Event, + z.B. humidity
        6. + +
      6. VALUE: aktueller Wert des Readings, ermittelt aus dem Event, + z.B. 71
        7. +
      7. UNIT: Einheit, ermittelt aus dem Event, z.B. %
        8. +
      + Der Wert des Rreadings ist optimiert für eine automatisierte Nachverarbeitung + z.B. yes ist transformiert nach 1 +

      + Die gespeicherten Werte können mittels GET Funktion angezeigt werden: +
        + get myDbLog - - 2012-11-10 2012-11-10 KS300:temperature +
      +

      + Beispiel: +
        + Speichert alles in der Datenbank
        + + define myDbLog DbLog /etc/fhem/db.conf .*:.* +
      +

        + Durchd ie Angabe des Schlüsselworts all werden alle + Spalten der Datenbank ausgegeben. +
        • +
      • <from> / <to>
        + Wird benutzt um den Zeitraum der Daten einzugrenzen. Es ist das folgende + Zeitformat oder ein Teilstring davon zu benutzen:
        +
          YYYY-MM-DD_HH24:MI:SS
        • +
      • <column_spec>
        + Für jede column_spec Gruppe wird ein Datenset zurückgegeben welches + durch einen Kommentar getrennt wird. Dieser Kommentar repräsentiert + die column_spec.
        + Syntax: <device>:<reading>:<default>:<fn>:<regexp>
        +
          +
        • <device>

            +
          • int
            + Ermittelt den Zahlenwert ab dem Anfang der Zeichenkette aus der + Spalte "VALUE". Benutzt z.B. für Ausprägungen wie 10%. +
            • +
          • int<digit>
            + Ermittelt den Zahlenwert ab dem Anfang der Zeichenkette aus der + Spalte "VALUE", inclusive negativen Vorzeichen und Dezimaltrenner. + Benutzt z.B. für Ausprägungen wie -5.7°C. +
            • +
          • delta-h / delta-d
            + Ermittelt die relative Veränderung eines Zahlenwertes pro Stunde + oder pro Tag. Wird benutzt z.B. für Spalten die einen + hochlaufenden Zähler enthalten wie im Falle für ein KS300 Regenzähler + oder dem 1-wire Modul OWCOUNT. +
            • +
          • +
        • <regexp>
          + Diese Zeichenkette wird als Perl Befehl ausgewertet. $val ist der + aktuelle Wert die die Datenbank für ein Device/Reading ausgibt. + Die regexp wird vor dem angegebenen <fn> Parameter ausgeführt. +
          + Bitte zur Beachtung: Diese Zeichenkette darf keine Leerzeichen + enthalten da diese sonst als <column_spec> Trennung + interpretiert werden und alles nach dem Leerzeichen als neue + <column_spec> gesehen wird. +
