First-Time Setup of the Overwatch Monitoring Appliance

This article walks through the complete initial configuration (first-run wizard) for the Overwatch Monitoring Appliance after it has been deployed as a VM. You will configure networking, verify settings, deploy the VM agent, and enable IPFIX network flow collection.

Prerequisites

• Overwatch appliance VM deployed and powered on
• You know the assigned IP address (DHCP or static)
• Access to the VM console from Nutanix Prism Element or Prism Central

Step 1 – Log in to the Overwatch Appliance

From Nutanix Prism Element or Prism Central, open the console of the VM.

Log in using the default installer account:

• Username: logicapp
• Password: Support/4u

After login, you will be automatically redirected to the First-Run Configuration Wizard.

Security recommendation: After setup is complete, change the default password with: sudo passwd logicapp

Step 2 – Configure Network Settings

The setup wizard will prompt you to configure networking using either:

• DHCP, or
• STATIC IP

Static IP Configuration Fields

When selecting static, you will be prompted for:

• IP Address – Example: 10.126.0.201
• Subnet Mask (CIDR) – Example: 24
  This value MUST be entered in CIDR format only (for example: 24).
  Do not use dotted mask format like 255.255.255.0.
• Gateway – Example: 10.126.0.1
• DNS Servers – Example: 1.1.1.1 or 8.8.8.8,8.8.4.4

Step 3 – Verify Network Settings

After inputting network information you will be shown a summary similar to:

• Interface: ens3
• IP Address
• Subnet Mask (CIDR)
• Gateway
• DNS
• Mode: DHCP or STATIC

Confirm the settings by typing:

y

Once confirmed, the system will immediately apply the configuration.

Step 4 – VM Agent Deployment

Following network validation, the wizard will proceed to:

• Apply OS network configuration
• Auto-expand storage volumes
• Deploy the internal VM agent responsible for metrics and service orchestration

Console output resembles:

Applying the new network configuration...
Configuration applied successfully.
Expanding storage (LVM auto-expand)...
Storage expansion completed.
Deploying VM agent...

This stage typically takes 1–3 minutes to complete depending on compute and disk performance.

Step 5 – Begin IPFIX Configuration

Once the VM agent deployment is successful, the wizard prompts:

IPFIX Configuration
Configure IPFIX now? (y/n):

Select:

y

This launches the IPFIX configuration wizard.

Step 6 – IPFIX Collector Setup (ZFS Edition)

The wizard will display:

IPFIX Collector Configuration (ZFS Edition)

This will configure ZFS dataset 'ipfixpool/ipfix-data'
and deploy IPFIX + Vector + VictoriaLogs containers.

Confirm:

y

CPU Validation

The installer checks that minimum CPU requirements are met:

Detected:
  Sockets         : 1
  Total vCPUs     : 8
  Cores per socket: 8

CPU requirements satisfied (>= 8 vCPUs).

ZFS Pool Creation

If no IPFIX storage pool exists, the wizard will prompt:

ZFS pool/dataset 'ipfixpool' not found.
We can create a NEW pool using an empty disk.

Do you want to create a NEW ZFS pool 'ipfixpool'? (y/N):

Select:

y

The scanner will locate eligible disks:

Scanning for candidate disks...
[1] /dev/sdb (100G)

Select the disk to be used for the IPFIX pool:

Select a disk for ZFS pool 'ipfixpool' (1-1): 1

The installer formats the disk and creates:

• ZFS Pool: ipfixpool
• Dataset: ipfixpool/ipfix-data

After creation, IPFIX services are automatically deployed:

• Vector – Flow ingestion
• VictoriaLogs – Log indexing and storage
• IPFIX Collector

Step 7 – Setup Completion

When setup is complete, you will see the appliance status screen:

• Service: LogicApp – Running
• SSH: Running
• Appliance URL: https://<APPLIANCE-IP>:8443
• Hostname: logicapp

At this point:

• The appliance is fully deployed
• VM monitoring services are active
• IPFIX ingestion and storage are operational

Next Steps

Access Overwatch UI

https://<APPLIANCE-IP>:8443

Default credentials:

• Username: admin
• Password: Overwatch/4u

Configure Nutanix IPFIX Export

Deploy IPFIX exporters on each AHV host using:

ovs-vsctl -- --id=@ipfix create IPFIX \
  targets="<APPLIANCE-IP>:2055" \
  sampling=512 \
  obs_domain_id=1 \
  obs_point_id=1 \
  cache_active_timeout=60 \
  cache_max_flows=10000 \
  -- set Bridge br0 ipfix=@ipfix

Setup Summary

• Login to appliance console
• Configure DHCP or Static network (CIDR-only mask)
• Confirm network settings
• VM Agent deploys automatically
• IPFIX setup and ZFS pool initialization
• Flow ingestion and dashboards available
