cgminer erlaubt das Abrufen von Statistiken und Parametern via API (Application Programming Interface oder deutsch Anwendungsschnittstelle), z.B. Bestshare, die Anzahl gefundener Blöcke, aber auch das Setzen von Systemparametern während des Betriebes von außen, z.B. die Frequenz (MHz) oder den USB-waitfactor. Des Weiteren kann das Mining-Programm ferngesteuert werden. Aber eins nach dem anderen...
Für die Benutzung der API muss die Java Laufzeitumgebung installiert werden. Wir beziehen uns hier auf eine Linux-Umgebung auf einem Raspberry Pi 4.
Zuerst muss die passende Laufzeitumgebung für das System gesucht werden, das macht man mittels apt über den folgenden Befehl:
apt-cache search jreWas zu folgendem Output in der Konsole führt:

java-package - Utility for creating Java Debian packagesNun haben wir die richtige Laufzeitumgebung ermittelt (openjdk-11-jre-headless) und installieren diese wiederum mittels apt (Ich habe während der Installtion openjdk-11-jre-headless verwendet, openjdk-17-jre-headless sollte auch ohne weiteres möglich sein.):
apt-get install openjdk-11-jre-headlessNun sind wir bereit für die Konfiguration der Java API für cgminer.
Um die API benutzen zu können müssen wir cgminer mitteilen, dass Anfragen von außen (entweder vom Raspberry Pi selbst via 'localhost' oder aus einem privaten Adressbereich zu Hause (subnet xxx.xxx.xxx.0/24) akzeptiert werden und die Software Informationen über den Miningprozess nach außen mitteilt). Die Konfiguration kann entweder beim Start von cgminer als Parameter mitgegeben werden:
sudo ./cgminer_4.12.1/cgminer --api-listen --api-allow "W:192.168.2.0/24,W:127.0.0.1"Das vorangestellte W bedeutet dass auch Befehle mit Schreibzugriff auf den Miner von dieser Adresse entgegengenommen werden dürfen.
In meinem Beispiel erlaube ich Anfragen vom Raspi selbst aus via localhost 127.0.0.1 und aus dem privaten Adressbereich meines Subnetzes 192.168.168.xxx.
Diese Einstellung kann auch in der Konfigurationsdatei cgminer.conf gemacht werden:
...
"api-allow" : "W:192.168.2.0/24,W:127.0.0.1",
"api-description" : "cgminer 4.12.1",
"api-listen" : true,
"api-mcast-addr" : "224.0.0.75",
"api-mcast-code" : "FTW",
"api-mcast-des" : "",
"api-mcast-port" : "4028",
"api-port" : "4028",
"api-host" : "0.0.0.0",
...
⚠️ "api-host" : "0.0.0.0",ist eine wildcard und erlaubt API-Befehle von überall her von wo dieAPI.classaufgerufen wird.
Um API-Befehle ausführen zu können, muss man entweder den Pfad von cgminer mit angeben oder sich im Pfade des Programmes befinden. Dies verdeutliche ich beim ersten Befehl java API estats nachfolgend.
Alle Rückemdlungen der API sind im JSON format, mit der ersten Sektion als Status und mit der zweiten Sektion die angeforderten Werte beinhaltend.
Der Status hat folgendes Format:
STATUS=X,When=NNN,Code=N,Msg=string,Description=string|
STATUS=X Where X is one of:
W - Warning
I - Informational
S - Success
E - Error
F - Fatal (code bug)
When=NNN
Standard long time of request in seconds
Code=N
Each unique reply has a unique Code (See api.c - #define MSG_NNNNNN)
Msg=string
Message matching the Code value N
Description=string
This defaults to the cgminer version but is the value of --api-description if it was specified at runtime.
⚠️ Nicht alle Befehle wurden getestet. Manche Befehle funktionieren eingeschränkt, z.B.zerosetzt zwar die Statistiken zurück, verändert aber die Anzeige in der Text-basierten GUI von cgminer 4.12.1 in dem z.B. Frequenz und Target nicht mehr angezeigt werden. Also Vorsicht, alles auf eigene Gefahr!!

Man hat nicht immer Lust sich auf den Raspberry Pi einzuloggen und dort Skripte auszuführen, wenn man diese auch bequem auf dem Host-Rechner laufen lassen kann. Diese Methodik wurde und Linux und OSX ausprobiert, wo jeweils eine Bash zur Verfügung steht und Shell-Scripting sehr einfach mit Boardmitteln zulässt. Das Prinzip sollte unter Windows ähnlich sein, jedoch müssen entsprechende Ableitungen nach Windows selbst gezogen werden.
📝 Notiz: im Kapitel 💡 Hilfreiche Kommandos für erleichterte Bedienung unter Linux/Raspberry Pi stehen weitere Details zur erleichterten Bedienung von SSH (z.B. Starten von SSH ohne Passworteingabe).
Um die Java API von extern zu verwenden, muss zunächst die Klassenbibliothek API.class aus dem Verzeichnis von cgminer auf den aufrufenden PC übertragen werden. In Beispiel hier soll die Datei API.class vom Raspberry Pi (Raspiblitz) auf einen Linux Desktop Rechner kopiert werden. Unter Linux kann hierfür scp (secure copy) verwendet werden, dies kann in beide Richtungen geschehen bzw. von beiden Systemen aus aufgerufen werden: also entweder vom Raspberry Pi aus scp <Pfad>/API.class <USER>@<HOSTNAME>:<PFAD> oder vom Host-PC aus wie im Beispiel unten scp <USER>@<HOSTNAME>:<PFAD>/API.class <PFAD>.
Dazu wechseln wir in ein gewünschtes Verzeichnis auf dem Host-PC:
cd /home/<USER>/Scriptsund starten den Kopiervorgang:
scp admin@raspberrypi.local:/home/admin/Mining/cgminer_4.12.1/API.class .Der abschliessende . bedeutet im Kontext von scp <QUELLE> <ZIEL> dass das Ziel der gegenwärtige Pfad ist. Nach dem eingeben des Passwortes für den Zugriff auf den Raspi beginnt der Download und die Datei befindet sich im gewählten Ordner.
Beim Aufruf von cgminer muss man nun den Parameter --api-host "0.0.0.0" hinzufügen oder in der Konfigurations-Datei cgminer.conf die Variable API-host = "127.0.0.1" auf API-host = "0.0.0.0" ändern, so dass Anfragen an cgminer auch von einem externen API-Host zugelassen werden (0.0.0.0 ist hier eine wild card).
Nun kann man vom Host-PC aus die Java API bedienen nach dieser Syntax (ähnlich der Syntax auf dem Raspberry selbst):
java API summary raspberrypi.local:4028Und man sollte die Rückmeldung in der aufrufenden Konsole sehen können.
⚠️ Man muss sich für den Aufruf der API im Ordner der DateiAPI.classbefinden.
In dem man ein gewünschten Befehl an ssh anhängt, kann man diesen auch innerhalb einer ssh-Session ausführen lassen. Mehrere Befehle müssen dazu allerdings in der Übergabe mit && gebündelt werden:
ssh admin@raspberrypi.local "cd /home/admin/Mining && java API lcd"Der Output ist der gleiche wie wenn man java API lcd auf dem Raspberry Pi aufruft, jedoch wird diese an den aufrufenden PC umgeleitet. Einfach mal ausprobieren, es kann ja nichts kaputt gehen...
