💡 Hint

Common Mistakes

Using 'all' which would allow everyone

Using '0.0.0.0/0' which is too broad

Allowing 127.0.0.1 means only the local machine can access the metrics, which is common for security.

Common Mistakes

Using 'enable' or 'true' which are invalid values

Using 'active' which is not recognized

The correct directive syntax is stub_status on; to enable the status module.

💡 Hint

Common Mistakes

Turning stub_status off

Allowing '127.0.0.1' when network access is needed

Setting stub_status on; enables metrics. Allowing 192.168.1.0/24 permits access from the local network.

5fill in blank

hard

Fill all three blanks to create a Prometheus exporter config that enables metrics, allows local access, and denies others.

Nginx

location /metrics {
    stub_status [1];
    allow [2];
    deny [3];
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'off' instead of 'on'

Allowing 'all' instead of just localhost

Denying '127.0.0.1' which blocks local access

Enable metrics with on, allow local access with 127.0.0.1, and deny everyone else with all.
