Dashboard offers the insight of running tasks in Jina. With dashboard, one can analyze logs, design flows and view Jina Hub images.
π Features:
- Log streaming, real-time chart on log-level.
- Grouping logs by Pods, Executors. Full text search on logs.
- Drag & drop flow design, setting properties of each Pod via a webform.
- Flow can be imported from/exported to YAML.
- Monitor Jina "Hello, World!" with Dashboard

- Self-host Dashboard

Jina "Hello, World" is a simple demo of image neural search for Fashion-MNIST.
- Run the following command in the console
- (Python >=3.7 required)
JINA_LOG_PROFILING=1 jina hello-world
- ...or if you use Docker (no install required)
docker run -e "JINA_LOG_PROFILING=1" -p 5000:5000 jinaai/jina:devel hello-world --logserver
- (Python >=3.7 required)
- Open https://dashboard.jina.ai in your browser
It should start streaming. If not, please refer to this step.
Set environment variable
JINA_LOG_PROFILING
to1
to enable Task tab in the dashboard.
Log server is a helper thread in Jina flow. It exposes HTTP endpoints to the public which the dashboard can use to fetch logs, visualize the flow.
By default the log server is disabled. To enable it you can,
If you use Flow API in Python, |
from jina.flow import Flow
f = (Flow(logserver=True)
.add(...)
.add(...))
with f.build() as fl:
fl.index(...) |
...or write a Flow from YAML |
# myflow.yml
!Flow
with:
logserver: true
pods:
... f = Flow.load_config('myflow.yml')
with f.build() as fl:
fl.index(...) |
...or start a Flow from CLI |
jina flow --logserver --yaml-path myflow.yml |
...or start a Flow with Docker Container |
docker run -p 5000:5000 jina flow --logserver ... |
Either way, if you see the following logs show up in the console, then your log server is successfully running. You can now move to the next step.
Go to: https://dashboard.jina.ai
Click on the globe icon on the top-left corner to connect to the log server.
It should turn into a green check mark, which means the connection is success.
You should now see the log-streaming and flow visualization.
If it has a red cross, it means the connection is lost or the endpoint is not set correctly. Please move to the next step for instruction.
By default the configurations of the log server is as follows:
host: 0.0.0.0
port: 5000
endpoints:
log: /stream/log # fetching log in SSE stream
profile: /stream/profile # fetching profiling log in SSE stream
yaml: /data/yaml # get the YAML spec of a flow
shutdown: /action/shutdown # shutdown the log server
ready: /status/ready # tell if the log server is ready, return 200 if yes
You can customize the endpoints of the log server via a YAML, say mylogserver.yml
. Then pass it to the Flow API via
If you use Flow API in Python, |
f = Flow(logserver=True, logserver_config='mylogserver.yml') |
...or write a Flow from YAML |
!Flow
with:
logserver: true
logserver_config: mylogserver.yml |
...or start a Flow from CLI |
jina flow --logserver --logserver-config mylogserver.yml ... |
...or start a Flow with Docker Container |
docker run -p PORT:PORT -v "$(PWD)/mylogserver.yml:/mylogserver.yml" jina flow --logserver --logserver-config /mylogserver.yml ... |
Don't forget to update endpoint in the dashboard accordingly.
One can self-host a dashboard locally.
git clone https://github.com/jina-ai/dashboard.git && cd dashboard
.- Install dependencies using command
yarn
. - Run dashboard via the following ways .
node testServer
- testServer will be running on
http://localhost:5000
by default yarn start
- dashboard will be served on
http://localhost:3000
by default
yarn build
node dashboard
- dashboard will be served on
http://localhost:3030
by default
