Running with prometheus parameter

jtimon

Junos Telemetry Interface client

Setup

$ git clone https://github.com/nileshsimaria/jtimon.git
$ cd jtimon
$ make linux or make darwin
$ ./jtimon-linux-amd64 --help or jtimon-darwin-amd64 --help

Please note that if you use make to build source, it will produce binary with GOOS and GOARCH names e.g. jtimon-darwin-amd64, jtimon-linux-amd64 etc. Building the source using make is recommended as it will insert git-revision, build-time info in the binary.

To understand what targets are available in make, run the make help command as follows:

$ make help

Note

If you are cloning the source and building it, please make sure you have environment variable GOPATH is set correctly. https://golang.org/doc/code.html#GOPATH

Docker container

Alternatively to building jtimon native, one can build a jtimon Docker container and run it dockerized while passing the local directory to the container to access the json file.

To build the container:

make docker

Check the resulting image:

$ docker images jtimon
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
jtimon              latest              f1a794609339        7 minutes ago       24.5MB

Run it:

docker run -ti --rm -v ${PWD}:/u:ro jtimon --help

Or simply by calling ./jtimon, which is a symlink to launch-docker-container.sh, capable of launching the container by name with the current directory mounted into /u:

$ ./jtimon
Enter config file name: bla.json
2018/03/02 13:53:44 File error: open bla.json: no such file or directory

Config

To explore what can go in config, please use --explore-config option.

Except connection details like host, port, etc no other part of the config is mandatory e.g. do not use influx in your config if you dont want to insert data into it.

$ ./jtimon-linux-amd64 --explore-config                                                                                                                                   [8/1981]

I am explaining some config options which are not self-explanatory.

meta : send username and password over gRPC meta instead of invoking LoginCheck() RPC for authentication. 
Please use SSL/TLS for security. For more details on how to use SSL/TLS, please refer wiki
https://github.com/nileshsimaria/jtimon/wiki/SSL

cid : client id. Junos expects unique client ids if multiple clients are subscribing to telemetry streams.

eos : end of sync. Tell Junos to send end of sync for on-change subscriptions.

grpc/ws : window size of grpc for slower clients

Kafka Publish

To publish gRPC/Openconfig JTI data to Kafka, use the following json config.

$ cat kafka-test-1.json
{
    "host": "2.2.2.2",
    "port": 32767,
    "user": "username",
    "password": "password",
    "cid": "cid123",
    "kafka": {
        "brokers": ["1.1.1.1:9094"],
        "topic": "test",
        "client-id": "testjtimonmx86"
    },

    "paths": [
        {
            "path": "/interfaces",
            "freq": 10000
        }
    ]
}

Below are all possible Kafka config options.

type KafkaConfig struct {
	Version            string   `json:"version"`
	Brokers            []string `json:"brokers"`
	ClientID           string   `json:"client-id"`
	Topic              string   `json:"topic"`
	CompressionCodec   int      `json:"compression-codec"`
	RequiredAcks       int      `json:"required-acks"`
	MaxRetry           int      `json:"max-retry"`
	MaxMessageBytes    int      `json:"max-message-bytes"`
	SASLUser           string   `json:"sasl-username"`
	SASLPass           string   `json:"sasl-password"`
	TLSCA              string   `json:"tls-ca"`
	TLSCert            string   `json:"tls-cert"`
	TLSKey             string   `json:"tls-key"`
	InsecureSkipVerify bool     `json:"insecure-skip-verify"`
}

	case *na_pb.KeyValue_StrValue:
	floatVal, err := strconv.ParseFloat(v.GetStrValue(), 64)
	if err != nil {
	continue
	}
	fieldValue = floatVal
