ResponseTime, CpuPercentage and CycleDuration are floats (seconds and percent) but were mapped as long, so OpenSearch truncated them in the indexed values. Aggregations (avg, percentiles) therefore returned 0 for all sub-second response times, while _source kept the correct values. The new mapping only applies to newly created (weekly) indices; existing indices need a reindex to recover correct aggregations.

FIX: Use float mapping for ResponseTime, CpuPercentage and CycleDuration in ServiceMonitoring and AgentMonitoring so that aggregations are no longer truncated (existing indices need to be reindexed)
