How to get around memory limits in grafana?

There are a few ways to get around memory limits in Grafana:

1. Use a more powerful server or increase the resources allocated to your current server. This can help to provide more memory for Grafana to use.
2. Optimize your queries and dashboards to use less memory. This can involve reducing the amount of data being queried, removing unnecessary variables or filters, and simplifying the visualization.
3. Configure caching for your data sources to reduce the amount of data that needs to be stored in memory.
4. Consider using a time series database like InfluxDB or Prometheus that is designed for handling time series data and can more efficiently manage memory usage.
5. Upgrade to the latest version of Grafana, as newer versions may have improved memory management and performance optimizations.
