How to increase Grafana refresh rate frequency
Blog post from QuestDB
QuestDB is an open-source time-series database designed for high-demand scenarios, offering ultra-low latency and high ingestion throughput, making it ideal for applications ranging from trading floors to mission control. It supports data portability with native Parquet and SQL, ensuring no vendor lock-in. While Grafana, a popular tool for visualizing data, limits its default dashboard refresh rate to once every 5 seconds to ease server load, this rate may not suffice for real-time applications like financial market data. QuestDB can accommodate higher refresh rates, allowing for more current data visualization and smoother updates. The process involves adjusting Grafana's server settings to allow for refresh intervals below the standard 5 seconds, which can be especially beneficial in scenarios requiring immediate feedback, such as algorithmic trading or real-time monitoring systems. By configuring Grafana's minimum refresh interval setting, users can achieve more frequent updates, enhancing the real-time data experience in various use cases.
