Access Opensearch Dashboards
Assuming that you have a virtual environment available (as described in Step 1.Set up a virtual environment, open a browser and type there the following URL:
http://<dashboards_juju_public_address>:5601
The address of the unit is available in the juju status output of the opensearch-dashboards unit. For example, in the output from Step 2. Deploy, this would be 10.163.9.173.
You should see something like this:
Set up an Opensearch user
Set up a user using the data-integrator charm.
At deployment time the Opensearch index (in the example: index_name) has to be specified as well. This is an arbitrary, alphanumerical identifier of the users’ data space in Opensearch.
User creation takes affect when integrated against the opensearch charm.
$ juju deploy data-integrator --config index-name=<intex_name>
$ juju relate data-integrator opensearch
Note: this user will have normal privileges - meaning this user will only have access to the index it owns.
In case a broader access to the cluster’s indices is needed, it is possible to create an admin / privileged user as follows:
juju deploy data-integrator admin --config index-name=admin-index --config extra-user-roles="admin"
Note: Please only create admin users when extremely needed, and handle with special care as authenticating with an admin user grants full access to all indices in the cluster.
Retrieve user credentials running
juju run data-integrator/0 get-credentials
at the bottom of the output you should see something like:
password: 8kubD7nbWYZFHPVEzIVmTyqV42I7wHb4
<CA certificate here>
username: opensearch-client_15
Create the “index pattern”
Log in to the Dashboard using these credentials. Clicking the top left icon the main menu will pull down. Select Management / Dashboards Management here
Select Index patterns on the next view:
Click on create index pattern at the bottom.
Adding the index name that used for data-integrator deployment (in our example: testing) as an index pattern enables Dashboard access to the user’s Opensearch space.
Click on the Next step button, and finalize the index pattern creation.
As a verification, the user’s index metadata will display.
Add and visualize data
For test purposes, a simple method could do. Like generating data from the command-line, via the Opensearch API:
for ID in `seq 1 100`
do
curl -sk -u opensearch-client_15:8kubD7nbWYZFHPVEzIVmTyqV42I7wHb4 \
-XPUT https://10.4.151.211:9200/testing/_doc/${ID} \
-H "Content-Type: application/json" \
-d '{"test": "This is test ${ID}"}'
done
This is how raw data gets displayed in the Dashboard
Data Visualization
Opensearch Dashboards offers a variety of diagrams and data displays.
Choose Dashboards in the main left-side menu, and you will be presented to the selection:
