Prometheus-Schnittstelle
Information
Dieses Topic beschreibt die Prometheus-Schnittstelle, die ab S 39.5.37 genutzt werden kann, um Informationen über den Betrieb des Servers abzufragen/zu überwachen.
Konfiguration
Die Konfiguration erfolgt in der per Umgebungsvariablen im Manager-Container des PLANTA-Servers.
Defaultmäßig sind die folgenden Werte konfiguriert:
planta__server__webservices__prometheus__enable = falseplanta__server__webservices__prometheus__connection = 0.0.0.0:9999planta__server__webservices__prometheus__entrypoint = /metrics
Rückgabewerte
Metriken
Die Informationen werden im json-Format ausgegeben und haben diese Struktur:

# TYPE – Typ der Metrik (counter, gauge, histogram, summary)
# HELP – Beschreibung der Metrik
Metrikname – muss den Prometheus-Namenskonventionen entsprechen
Labels – Schlüssel/Wert-Paare in {...}
Wert (Zahl, float)
Alle Metriken des Servers haben das Präfix planta_server_, dies erleichtert die Zuordnung/Auffindung in anderen Systemen.
Verfügbare Metriken
planta_server_sum_active_sessions - Summe aller aktiven Sessions
planta_server_count_max_active_sessions_total - Maximale Anzahl aktiver Session
planta_server_track_active_sessions_by_mode - Anzahl aktiver Session per SessionMode
planta_server_count_sessions_by_mode_total - Summe aller bisherigen Sessions per SessionMode
Label: sessionMode
