runZero Tasks

RunZero Tasks (Scans)

Overview

RunZero tasks represent network discovery scans. Each scan is executed by an explorer (scan agent), targets a set of IP ranges or subnets, and discovers assets, services, and network topology. This skill covers creating, managing, and reviewing scan tasks.

Key Concepts

Explorers

Explorers are RunZero's scan agents deployed on the network:

Type	Description
Managed Explorer	Deployed on-premises, managed via RunZero Console
Hosted Explorer	Cloud-hosted by RunZero for external scanning

Each explorer is assigned to a site and executes scans within that network segment.

Scan Types

Type	Description
Discovery	Full asset and service discovery
Quick	Fast ping sweep to identify live hosts
Targeted	Scan specific ports or protocols

Scan Targets

Targets are specified as:

• CIDR notation: 192.168.1.0/24
• IP ranges: 10.0.0.1-10.0.0.254
• Individual IPs: 172.16.0.1
• Multiple entries separated by commas or newlines

Scan Rate

Scan rate controls how aggressively the explorer scans:

Rate	Description
slow	Minimal network impact, longer scan time
normal	Balanced speed and network impact
fast	Faster scan, higher network utilization
max	Maximum speed, highest network impact

API Patterns

List Tasks

runzero_tasks_list

Parameters:

• site_id -- Filter by site
• status -- Filter by status (running, completed, stopped, error)
• count -- Results per page
• offset -- Pagination offset

Example response:

{
  "tasks": [
    {
      "id": "task-uuid-123",
      "name": "Weekly Discovery - ACME HQ",
      "site_id": "site-uuid-456",
      "status": "completed",
      "type": "discovery",
      "targets": "192.168.0.0/16",
      "explorer_id": "explorer-uuid-789",
      "created_at": "2026-03-27T02:00:00Z",
      "completed_at": "2026-03-27T03:45:00Z",
      "stats": {
        "assets_found": 342,
        "services_found": 1205,
        "new_assets": 5
      }
    }
  ]
}

Get Task Details

runzero_tasks_get

Parameters:

• task_id -- The specific task UUID

Returns full scan details including targets, results, timing, and discovered asset/service counts.

Create a Scan Task

runzero_tasks_create

Parameters:

• site_id -- Site to scan (required)
• targets -- IP ranges to scan (required)
• explorer_id -- Explorer to execute the scan (required)
• name -- Human-readable task name
• scan_rate -- Scan speed (slow, normal, fast, max)
• probes -- Specific probes to enable (e.g., arp,syn,connect)

Stop a Task

runzero_tasks_stop

Parameters:

• task_id -- The running task to stop

Common Workflows

Initiate a Discovery Scan

1. Call runzero_sites_list to identify the target site
2. Call runzero_explorers_list to find available explorers for the site
3. Call runzero_tasks_create with the site, explorer, and target ranges
4. Monitor progress with runzero_tasks_get
5. Review results once completed

Review Recent Scan Results

1. Call runzero_tasks_list with status=completed
2. Sort by completion time
3. For each task, summarize asset and service discovery counts
4. Flag tasks with errors or unexpected results

Explorer Health Check

1. Call runzero_explorers_list to get all explorers
2. Check each explorer's last check-in time
3. Flag explorers that are offline or haven't reported recently
4. Verify each site has at least one healthy explorer

Scan Coverage Analysis

1. List all sites and their configured target ranges
2. List recent completed scans per site
3. Identify sites with no recent scans
4. Recommend scan schedules for gaps

Error Handling

Explorer Offline

Cause: The selected explorer is not connected Solution: Verify explorer connectivity; check the host machine

Invalid Targets

Cause: Malformed CIDR notation or IP range Solution: Verify target format; use CIDR or dash-separated ranges

Scan Timeout

Cause: Large target range or slow scan rate Solution: Split targets into smaller subnets; increase scan rate

Best Practices

• Schedule recurring scans for each site to maintain current inventory
• Use normal scan rate for routine scans; reserve fast/max for urgent discovery
• Name tasks descriptively (e.g., "Weekly Discovery - ClientName HQ")
• Review scan results for new assets after each scan
• Monitor explorer health to ensure scan coverage
• Split large networks into smaller scan targets for manageability
