As shown in the screenshot under, question load spikes correlate with spikes in lookup thread pool queue measurement, since the node makes an attempt to keep up with price of query requests.
Follow Monitoring and optimizing an Elasticsearch cluster is critical to be certain its performance, balance and reliability.
Elasticsearch also recommends using doc values Any time attainable mainly because they serve the same objective as fielddata. On the other hand, given that they are stored on disk, they do not depend upon JVM heap. Although doc values cannot be utilized for analyzed string fields, they do help you save fielddata utilization when aggregating or sorting on other sorts of fields.
As an illustration, using Prometheus with Grafana will involve amassing and exporting metrics, though starting alerts in Grafana requires expertise in PromQL syntax, introducing complexity to the educational curve.
