Anonymous Access for Wall Dashboards

Scenario

A lot of people who have a NetEye monitoring system will set up a Wall Dashboard to display the status of their most important services and vital performance data.

If these Dashboards are built using Grafana (in the ITOA menu in NetEye 4), you will encounter the problem that you will need to bypass the initial NetEye login screen where it prompts you for credentials.

Anonymous Access: Security Notice

Here is a way to enable anonymous access to Grafana.  However, it’s important to protect it by only allowing access from the Wall Dashboards!

Furthermore, it’s possible to restrict anonymous access to a specific Grafana Organization, publishing only those Dashboards there that can be publicly accessible.

Web Server Configuration

The configuration is quite simple: we will need to create a new web service without authentication.

To do this, connect to NetEye and edit the file:

/etc/httpd/conf/httpd.conf

Now add a second listener just under the line “Listen 80”:

Listen 81

Then add the following block at the end of the configuration file:

Note: Put all the IP addresses for the Wall Dashboard in the line “Allow from”, which is indicated above as a.a.a.a b.b.b.b c.c.c.c. For NetEye 4, you need to configure the:

firewall-cmd --permanent --add-port=81/tcp
firewall-cmd –reload

Then the httpd service must be restarted:

  • NetEye 3: service httpd restart
  • Neteye 4: systemctl restart httpd.service

Grafana Configuration

The second configuration step is to enable anonymous access in Grafana.  Open the file:

  • NetEye 3: /var/lib/neteye/grafana/etc/grafana.ini
  • NetEye 4: /neteye/shared/grafana/conf/grafana.ini

Look for the [auth.anonymous] section and edit it as follows:

[auth.anonymous]
# enable anonymous access
enabled = true
# specify organization name that should be used for unauthenticated users
org_name = "Main Org."
# specify role for unauthenticated users
org_role = Viewer

The Organization “Main Org.” is the default one. You can change it to another existing Grafana Organization name to limit the number of visible Dashboards.

The final step is to restart the grafana-server service:

  • NetEye 3: service grafana-server restart
  • Neteye 4: systemctl restart grafana-server.service

Anonymous Access from Wall Dashboards

Now our configuration is finished.  You can now access the Wall Dashboards using this web link:

http://neteye:81/grafana

(where “neteye” is the name of your NetEye server)
