Elastic Load Balancing and Amazon X-Ray
Elastic Load Balancing application load balancers add a trace ID to incoming HTTP requests in a header
named X-Amzn-Trace-Id
.
X-Amzn-Trace-Id: Root=1-5759e988-bd862e3fe1be46a994272793
X-Ray trace ID format
An X-Ray trace_id
consists of three numbers separated by hyphens. For example,
1-58406520-a006649127e371903a2de979
. This includes:
-
The version number, which is
1
. -
The time of the original request in Unix epoch time using 8 hexadecimal digits.
For example, 10:00AM December 1st, 2016 PST in epoch time is
1480615200
seconds or58406520
in hexadecimal digits. -
A globally unique 96-bit identifier for the trace in 24 hexadecimal digits.
Load balancers do not send data to X-Ray, and do not appear as a node on your service map.
