All the logs are not appearing on the Azure Managed Grafana dashboard

My total log volume is approximately 100,000 entries over a 20-minute duration. When I attempt to query this data on my Azure Managed Grafana server—specifically for my Azure App Service running a NestJS application—the server struggles to handle the load. After some time, it either becomes unresponsive or takes an excessive amount of time to return results. Could you please advise on how I can optimize or resolve this issue?
