<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class="">Hallo Rupert,<div class=""><br class=""></div><div class="">vielen Dank für die Anregungen. Den minütlichen aggregate.php-Job kann ich mir tatsächlich sparen. Bis vor kurzem hatte ich noch 30 Sekunden Aggtime - die habe ich verlängert, seit ich die Werte zur Ansteuerung unterschiedlicher PV-geführter Regelungsprozesse aus dem Push-Server mit sehr kurzen Intervallen abgreifen kann - das ist schon super! Die Aggtime werde ich vermutlich noch weiter verlängern, um DB-Volumen einzusparen.</div><div class=""><br class=""></div><div class="">Hinsichtlich der SD-Karte habe ich gute Erfahrungen damit gemacht, das SWAP-File zu disablen, damit nicht permanent auf der SD-Card hermgerödelt wird. Meine Karten halten inzwischen mehrere Jahre durch. Es kommt halt nur zu Problemen, wenn mehr Arbeitsspeicher erforderlich wird, z.B. beim Einspielen eines größeren DB-Restore oder wenn ich den vzlogger neu compilieren möchte; dann schalte ich nur für diesen Zweck das Swapping ein.</div><div class=""><br class=""></div><div class="">Mit SSD hatte ich es mal versucht mit einer Transcend JetDrive SSD, die beim Upgrade eines Apple übrig blieb. Leider wollen die Raspis nicht mir dieser SSD-Type sprechen und da habe ich die Versuche wieder eingestellt. Ist schon seltsam, denn an allen anderen Rechnern muss man nur einstecken und los gehts.</div><div class=""><br class=""></div><div class="">Zu Deinem Hinweis zu Aggregate/max habe ich noch eine Frage. Ich dachte, dass die Middleware bei Energiezähler-Kanälen jeweils zwischen zwei Tupels differenziert und einen Leistungswert ermittelt, der im Frontend angezeigt wird. Wenn ich mir vorstelle, ich erhalte durch Aggtime 10 Differentiale (Leistungswerte), repräsentiert das Differntial zwischen dem letzten und damit höchsten Energiezählerwert und dem vorletzten nicht zwingend die größte Leistung, die in dem betrachteten Intervall auftritt.</div><div class=""><br class=""></div><div class="">Das Problem mit dem voll laufenden Arbeitsspeicher scheint sich aber mehr und mehr auf den push-server zu konzentrieren, denn bereits zwei Installationen zeigen die gleichen Probleme. Die Installation auf dem 8GB Raspi 4 ist nur weniger auffällig, weil der Speicher viel länger braucht, um voll zu laufen - wenn auch im Log die gleichen Fehler auflaufen, kommt es nicht zu spürbaren Störungen am Frontend. Der Raspi 3 spinnt bereits nach 24 h.</div><div class=""><br class=""></div><div class="">Interessant ist, dass der Push-Server irgendwann anfängt, zig Tuples mit größerer Zeitverzögerung raus zu hauen. Währenddessen zeigt der Raspi extreme Reaktionszeiten und man kann sich nur noch mit großer Geduld per SSH einloggen (Headless).</div><div class=""><br class=""></div><div class=""><div style="margin: 0px;

<br class=""><p class="">Nur damit hier keine Missverständnisse stehen bleiben: Die
Aggregation (aggtime, aggmode usw.) im vzlogger hat <b class="">nichts</b>
mit der Aggregation auf der Datenbank (aggregate.php) zu tun.</p><p class="">Ersteres dünnt "high speed" Daten aus, so dass z.B. nur alle 60
sec ein Wert (der Mittelwert, das Maximum -- je nach aggmode) an
die Middleware gesendet und in der DB gespeichert wird. Der Rest
wird verworfen.<br class="">
</p><p class="">Letzteres erzeugt verdichtete Daten für das Frontend, so dass der
Bildaufbau bei Auswahl eines längeren Zeitraums schneller geht.
Die Grafik für ein ganzes Jahr auf Basis von Minutenwerten z.B.
müsste 8760*60 = über eine halbe Million Datensätze rendern bzw.
intelligent verdichten. Diese Verdichtung macht aggregate.php und
legt das Ergebnis zusätzlich in der DB ab.</p><p class="">Wenn Du in vzlogger.conf aggtime immer auf mindestens 60 sec
stehen hast, macht aggregate.php -l minute keinen Sinn: Dann
gibt's nichts zu verdichten. :-)</p><p class="">Übrigens: Wenn Dir die Zählerstände (OBIS 1-0:?.8.?) alle 60 sec
reichen, solltest Du in diesen Channels aggmode auf max stellen.
Zählerstände zählen immer nur nach oben. Mit max bekommst Du den
letzten, zu dem dann auch der Zeitstempel passt.</p><p class=""><br class="">

Dass die Lebensdauer dieser Karten, auch bei "schonenden" =
vergleichsweise seltenen Schreibvorgängen auf die Datenbank, meist
schon nach wenigen Monaten durch ist, ist Dir hoffentlich bekannt
und bewusst. Eine kleine Investition in eine SSD oder einen
FIT-Stick kann viele Stunden Fehlersuche und Neuinstallation
vermeiden. Ich spreche da aus leidvoller Erfahrung...<div class=""><br class="webkit-block-placeholder"></div><p class="">Gruß von Lech und Wertach</p><p class="">Rupert<br class="">
