Problem to use chirpstack simulator

I was interested by chirpstack simulator tool. I have tried to set it up .
I have done configuration according to my setup
When i lauch it seems there is no error but nothing appen …
is there logs somewhere to understand what happen ?

user1@cl3vm1130:~/chirpstack-simulator/chirpstack-simulator-master$ ./build/chirpstack-simulator -c chirpstack-simulator.toml
INFO[0000] starting ChirpStack Simulator docs=“https://www.chirpstack.io/” version=

Below the configuration file i m using
$ cat chirpstack-simulator.toml
[general]

Log level

debug=5, info=4, warning=3, error=2, fatal=1, panic=0

log_level=4

Application Server configuration.

[application_server]

API configuration.

This configuration is used to automatically create the:

* Device profile

* Gateways

* Application

* Devices

[application_server.api]

JWT token.

The JWT token to connect to the ChirpStack Application Server API. This

token can be generated using the login API endpoint. In the near-future

it will be possible to generate these tokens within the web-interface:

https://github.com/brocaar/chirpstack-application-server/pull/421

jwt_token=“eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOiJjaGlycHN0YWNrLWFwcGxpY2F0aW9uLXNlcnZlciIsImV4cCI6MTYwNjQyNjU2NSwiaWQiOjEsImlzcyI6ImNoaXJwc3RhY2stYXBwbGljYXRpb24tc2VydmVyIiwibmJmIjoxNjA2MzQwMTY1LCJzdWIiOiJ1c2VyIiwidXNlcm5hbWUiOiJhZG1pbiJ9.42SWTeZTXoKat2sCL9qretRW26YzSeOTbN7z7XkgUTY”

Server.

This must point to the external API server of the ChirpStack Application

Server. When the server is running on the same machine, keep this to the

default value.

server=“10.35.97.101:8080”

Insecure.

Set this to true when the endpoint is not using TLS.

insecure=true

MQTT integration configuration.

This integration is used for counting the number of uplinks that are

published by the ChirpStack Application Server integration.

[application_server.integration.mqtt]

MQTT server.

server=“tcp://10.35.97.101:1883”

Username.

username=""

Password.

password=""

Network Server configuration.

This configuration is used to simulate LoRa gateways using the MQTT gateway

backend.

[network_server]

MQTT gateway backend.

[network_server.gateway.backend.mqtt]

MQTT server.

server=“tcp://10.35.97.101:1883”

Username.

username=""

Password.

password=""

Simulator configuration.

Example:

[[simulator]]

# Service-profile ID.

# It is recommended to create a new organization with a new service-profile

# in the ChirpStack Application Server.

service_profile_id=“6689481a-4e01-438c-a8f0-45b6f5adb78b”

# Duration.

# This defines the duration of the simulation. If set to ‘0s’, the simulation

# will run until terminated. This includes the activation time.

duration=“5m”

# Activation time.

# This is the time that the simulator takes to activate the devices. This

# value must be less than the simulator duration.

activation_time=“1m”

# Device configuration.

[simulator.device]

# Number of devices to simulate.

count=5

# Uplink interval.

uplink_interval=“2m”

# FPort.

f_port=10

# Payload (HEX encoded).

payload=“010203”

# Frequency (Hz).

frequency=868100000

# Bandwidth (Hz).

bandwidth=125000

# Spreading-factor.

spreading_factor=7

# Gateway configuration.

[simulator.gateway]

# Event topic template.

event_topic_template=“gateway/{{ .GatewayID }}/event/{{ .Event }}”

# Command topic template.

command_topic_template=“gateway/{{ .GatewayID }}/command/{{ .Command }}”

# Min number of receiving gateways.

min_count=3

# Max number of receiving gateways.

max_count=5

Prometheus metrics configuration.

Using Prometheus (and Grafana), it is possible to visualize various

simulation metrics like:

* Join-Requests sent

* Join-Accepts received

* Uplinks sent (by the devices)

* Uplinks sent (by the gateways)

* Uplinks sent (by the ChirpStack Application Server MQTT integration)

[prometheus]

IP:port to bind the Prometheus endpoint to.

Metrics can be retrieved from /metrics.

I had a quick look at the config above. When you say nothing happens, what do you mean?

The uplink_interval here is set to be 2m, so you would have to wait 120 seconds for any frames in your LoRaWan Frames tab. I have had plenty of trouble with simulator so would like to help if I can.
