Amazon CloudWatch Logs Insights 查詢 P90 回應時間

依全域解析程式的 P90 回應時間

fields @timestamp,
      enrichments.0.value as GlobalResolverId,
      (response_time - query_time) as ResponseTime
| filter ispresent(response_time) and ispresent(query_time)
| stats pct(ResponseTime, 90) as P90ResponseTime by GlobalResolverId

Access Token 權杖過期前的天數

fields @timestamp,
      enrichments.0.data.token_id as AccessTokenId,
      enrichments.0.data.token_ttl_days as DaysUntilExpiry
| filter ispresent(enrichments.0.data.token_ttl_days)
| stats latest(DaysUntilExpiry) by AccessTokenId
