Compatibility with current versions of nats

[mar1ged]

When I use nats-top with a current version of nats it complains and fails:

8934] 2020/05/24 22:09:23.784078 [ERR] 127.0.0.1:37908 - cid:5 - Client parser ERROR, state=0, i=0: proto='"\x16\x03\x01\x00\u007f\x01\x00\x00{\x03\x03\xdb\xe6\xb3&\"k\x9b\a\xa9s\xee\a(V\xcc~4\xcek\xa5\x02"...'
[8934] 2020/05/24 22:09:23.784087 [DBG] 127.0.0.1:37908 - cid:5 - Client connection closed: Protocol Violation

If I try to compile nats-top it doesn't work either:

./nats-top.go:114:17: cannot use sortOpt (type "github.com/nats-io/gnatsd/server".SortOpt) as type "github.com/nats-io/nats-top/vendor/github.com/nats-io/gnatsd/server".SortOpt in assignment

Hi @mar1ged you are pointing nats-top to the client port from NATS which is 4222, but the one that you are looking for is the monitoring port (which is often 8222). In case cannot build locally you can get a build from master as well using gobinaries:

curl -sf https://gobinaries.com/nats-io/nats-top | PREFIX=. sh
./nats-top -v
/.nats-top -s demo.nats.io
