Hi,

It wasn't clear to me the difference between latency and service\_time mentioned here

> **[Metrics — Rally 2.0.2 documentation](https://esrally.readthedocs.io/en/stable/metrics.html#metric-keys)**

If I understand this correctly, `service_time` sounds like a representation of "took" that ES returns in responses, or is it even more granular like per shard time?  
Latency seems like the HTTP response times?  
Is my understanding correct?

Can someone please clarify?

Thanks,  
Pradeep.

Hi,

please [see the respective FAQ section](https://esrally.readthedocs.io/en/stable/faq.html#what-does-latency-and-service-time-mean-and-how-do-they-related-to-the-took-field-that-elasticsearch-returns) which should answer your question in great detail. 🙂
