Usecase where we need to pressist data to ClickHouse the sooner the better...

Inizia da graphouse.properties, in particolare dalle impostazioni di graphouse.cacher batching e di ClickHouse mostrate nell’issue. Traccia il modo in cui queste impostazioni controllano la persistenza delle metriche e definisci la configurazione o il comportamento necessari affinché i dati raggiungano ClickHouse entro 30 secondi; il lavoro è completato quando l’obiettivo di latenza e le opzioni supportate sono documentati o verificabili tramite test.

Hi, we are a bit new to grafite... since we are using ClickHouse we also decided to use graphouse for telemetry. So we are using Grafana with ClickHouse datasource, and going directly to graphouse.data to get telemetry and what we are seeing data is actually 1 min to 5 min lag depending on volume and frequency. So I suspect is graphouse catches some data in memory using the options below (in #Mretric search and tree.. section )... if this is true what is the best setting for pushing metrics to ClickHouse no more than 30 seconds old? Is this possible? What are our options? Any advice is appreciated

We are running on 2 CPU / 8 GB RAM server
