# 管道指标示例
<a name="monitor-response"></a>

将 Amazon Personalize 搜索排名插件应用于 OpenSearch 查询时，您可以通过获取搜索管道的指标，监控插件。管道指标包括诸如 `personalized_search_ranking` 响应处理器的失败请求数量之类的统计信息。

 以下代码显示了从 OpenSearch 返回的管道指标的摘录。它仅显示包含两个不同管道统计信息的 `pipelines` 对象。对于每个管道，您可以在 `personalized_search_ranking` 响应处理器列表中找到 Amazon Personalize 搜索排名插件指标。有关所有指标的完整示例，请参阅[搜索管道指标](https://opensearch.org/docs/latest/search-plugins/search-pipelines/search-pipeline-metrics/)。
