Quick start

  1. Deploy from the Azure Marketplace (Get It Now → Create), choosing your SSH key at the Administration step.
  2. Allow inbound SSH (22) for yourself plus the application port(s): 8428 — to your collectors and dashboards only — restrict to your own IP where possible. The in-image firewall already allows them; only the Network Security Group (NSG) keeps them closed.
  3. Open http://<VM-IP>:8428/vmui/ with the generated Basic Auth credentials (see First login below).
  4. Add VictoriaMetrics as a Prometheus data source in Grafana (URL http://<VM-IP>:8428 with Basic Auth).

First login / credentials

This image generates its admin credential on the VM at first boot — nothing is pre-set. SSH into the VM with the username + key you chose at deploy, then print the generated credential:

ssh <your-username>@<VM-IP>
sudo cat /root/victoriametrics-admin-credentials.txt

Sign in as vmadmin (VM_AUTH_USER) with the generated password (Basic Auth).

  1. Print the credential file: username vmadmin and the generated password.
  2. Open http://<VM-IP>:8428/vmui/ and sign in with Basic Auth; API check: curl -u 'vmadmin:<password>' http://<VM-IP>:8428/health.
  3. Point Prometheus remote_write / vmagent at http://<VM-IP>:8428/api/v1/write with basic_auth; rotate the password in /etc/default/victoriametrics and put TLS in front before sending real data.

Sign in as admin (unless noted), then change the password immediately. The file is root-only and can be deleted once the password is stored securely.
