--------------------------------
Summary: Uniform name of http method of client metric to lowerCase
Key: KNOX-2953
URL: https://issues.apache.org/jira/browse/KNOX-2953
Project: Apache Knox
Issue Type: Improvement
Components: Metrics
Reporter: liang.feng
Attachments: gateway-client-metric.png
The metric name starting with client should set httpMethod to lowercase, when
build metric name, just like the service metric name at
[InstrHttpClientBuilderProvider.methodNameString|https://github.com/apache/knox/blob/master/gateway-server/src/main/java/org/apache/knox/gateway/services/metrics/impl/instr/InstrHttpClientBuilderProvider.java#L68
]
There are many similar metric names now，due to name of httpMethod is
non-uniform.
For example：
When I query from HBase with curl command , The command curl -X Get 和 curl -X
GET will generate two similar metric name

We should uniformly change the method name to lowercase so that the metric
names of service and client are unified
