Jtimon and Healthbot

Healthbot uses jtimon to collect telemetry on junos devices

Configure healthbot to collect telemetry on Junos devices.

Run this command to execute the script enforce_interfaces_admin_status.py
This script will configure healthbot to subscribe to the openconfig resource /interfaces on devices vMX1 to vMX7 with a frequency of 15s.

$ python ./enforce_interfaces_admin_status.py

To Display information about sensors, run this command on a Junos device:

jcluser@vMX1> show agent sensors

To verify if there is an established connection between jtimon (grpc client) and a Junos device (grpc server), run this command on a Junos device:

jcluser@vMX1> show system connections | grep 32768
tcp4       0      0  100.123.1.0.32768                             100.123.35.0.53404                            ESTABLISHED
tcp46      0      0  *.32768                                       *.*                                           LISTEN

Jtimon hands on

Run these commands on healthbot to connect to jtimon container

$ docker ps | grep jtimon

$ docker exec -it <container-id> sh

Example with container_id 25791fbca153

$ docker exec -it 25791fbca153 sh
/u #

Run this command on jtimon container to read the jtimon config-file-list

/u # more /etc/jtimon/jti_oc_jtimon.json
{
    "config_file_list": [
        "/etc/jtimon/configs/vMX1.conf",
        "/etc/jtimon/configs/vMX2.conf",
        "/etc/jtimon/configs/vMX3.conf",
        "/etc/jtimon/configs/vMX4.conf",
        "/etc/jtimon/configs/vMX5.conf",
        "/etc/jtimon/configs/vMX6.conf",
        "/etc/jtimon/configs/vMX7.conf"
    ]
}

Run this command on jtimon container to list the jtimon config files

/u # ls /etc/jtimon/configs/
vMX1.conf  vMX2.conf  vMX3.conf  vMX4.conf  vMX5.conf  vMX6.conf  vMX7.conf

Run this command on jtimon container to read a jtimon config file

/u # more /etc/jtimon/configs/vMX1.conf
{
    "cid": "vmx_vMX1_100.123.35.0",

        }
    ],
    "log": {
        "verbose": false
    }
}

Run this command on jtimon container to exit the container

/u # exit
$ 

run this command on healthbot to show logs from jtimon container

$ docker logs 25791fbca153 --tail 30
