9915d02022 *: Change gRPC proxy to expose etcd server endpoint /metrics 
This PR resolves an issue where the `/metrics` endpoints exposed by the proxy were not returning metrics of the etcd members servers but of the proxy itself.

f0e6c10aba grpcproxy: return error to client during watch create 
Now returns errors from checkPermissionForWatch() via the CancelReason
field. This allows clients to understand why the watch was canceled.
Additionally, this change protects a watch from starting and that
otherwise might hang indefinitely.

b1dd19a7aa *: don't use string literals directly in grpc metadata 
Current etcd code uses the string literals ("token", "authorization")
as field names of grpc and swappger metadata for passing token. It is
difficult to maintain so this commit introduces new constants for the
purpose.

e8c18e3368 proxy: handle authed snapshot request in grpcproxy 
Like the previous commit 10f783efdd12, this commit lets grpcproxy
forward an auth token supplied by its client in an explicit
manner. snapshot is a stream RPC so this process is required like
watch.

Requests of linearizable range don't touch the cache of grpcproxy. So
incrementing the miss count wouldn't be meaningful.

grpcproxy: Disable fast fail on lease grant call to cluster
 2017-06-19 15:04:25 -07:00
Iwasaki Yudai
df2cc4bc8c grpcproxy: Disable fast fail on lease grant call to cluster 
Problem Observed
----------------

When there is no etcd process behind the proxy,
clients repeat resending lease grant requests without delay.
This behavior can cause abnormal resource consumption on CPU/RAM and
network.

Problem Detail
--------------

`LeaseGrant()` uses a bare protobuf client to forward requests.
However, it doesn't use `grpc.FailFast(false)`, which means the method returns
an `Unavailable` error immediately when no etcd process is available.
In clientv3, `Unavailable` errors are not considered the "Halt" error,
and library retries the request without delay.
Both clients and the proxy consume much CPU cycles to process retry requests.

Resolution
----------

Add `grpc.FailFast(false))` to `LeaseGrant()` of the `leaseProxy`.
This makes the proxy not to return immediately when no etcd process is
available. Clients will simply timeout requests instead.
