handle the case where we request a server-id which is this current server
update docs, error on node and server id params
more accurate names for tests
use shared no leader err, formatting
rm bad comment
remove redundant variable
Addresses feedback around monitor implementation
subselect on stopCh to prevent blocking forever.
Set up a separate goroutine to check every 3 seconds for dropped
messages.
rename returned ch to avoid confusion
Adds new package that can be used by client and server RPC endpoints to
facilitate monitoring based off of a logger
clean up old code
small comment about write
rm old comment about minsize
rename to Monitor
Removes connection logic from monitor command
Keep connection logic in endpoints, use a channel to send results from
monitoring
use new multisink logger and interfaces
small test for dropped messages
update go-hclogger and update sink/intercept logger interfaces
Adds nomad monitor command. Like consul monitor, this command allows you
to stream logs from a nomad agent in real time with a a specified log
level
add endpoint tests
Upgrade go-hclog to latest version
The current version of go-hclog pads log prefixes to equal lengths
so info becomes [INFO ] and debug becomes [DEBUG]. This breaks
hashicorp/logutils/level.go Check function. Upgrading to the latest
version removes this padding and fixes log filtering that uses logutils
Check
AgentMonitor is an endpoint to stream logs for a given agent. It allows
callers to pass in a supplied log level, which may be different than the
agents config allowing for temporary debugging with lower log levels.
Pass in logWriter when setting up Agent
Currently when hitting the /v1/agent/self API with ACL Replication
enabled results in the token being returned in the API. This commit
redacts that information, as it should be treated as a shared secret.
The ForceLeaveRequest endpoint may only be called on servers, but the
code was using a Client to resolve tokens. This would cause a panic when
an agent wasn't both a Server and a Client.
This PR sorts the output of the endpoint since its results are used as
part of Consul checks to avoid the value changing unnecessarily.
Fixes https://github.com/hashicorp/nomad/issues/3211
If Config.Vault.Token is defined, /v1/agent/self will return the string
`<redacted>`. If the token is not set, This endpoint will continue to
return the empty string.

rpcproxy is refactored into serverlist which prioritizes good servers
over servers in a remote DC or who have had a failure.
Registration, heartbeating, and alloc status updating will retry faster
when new servers are discovered.
Consul discovery will be retried more quickly when no servers are
available (eg on startup or an outage).
When an agent is running a server, the list of servers includes the
Raft peers. When the agent is running a client (which is always the
case?), include a list of the servers found in the Client's RpcProxy.
Dedupe and provide a unique list back to the caller.
