  - Assets
    The Assets page shows all the physical components and systems in the local network environment and their associated details. It also lets you perform actions on those assets. Depending on the nodes and components involved, assets can range from a simple personal computer to an operational technology (OT) device.
  - Queries
    You can use the Nozomi Networks Query Language (N2QL) syntax to create complex data processes to obtain, filter, and analyze lists of information from the Nozomi Networks software.

    The Smart Polling page lets you view and manage Smart Polling.
  - Arc in Guardian
    Arc™ is a host-based sensor that detects and defends against malicious or compromised endpoints, and insider attacks. You can use Arc sensors to aggregate data for analysis and reports, either on-premises, or in the Vantage cloud.
  - Network
    The Network page gives you access to multiple pages that show nodes, links, sessions in tabular format and graphs and traffic in a graphical format.

Request a continuous trace

The profile settings menu lets you request a trace that has only the disk size constraint.

About this task

The maximum count of packets, and the run time, constrain regular traces. For example, being constrained to capture at most 1000 packets in no more than one minute. A continuous trace does not have such limits. It collects packets without constraints, as long as the disk has free space to store the captured traffic. The packets are then saved as individual files that are 100 megabyte (MB) in size.

Procedure

In the top navigation bar, select
A menu shows.
Select Other actions.
Select Continuous trace.
A dialog shows.
In the Packet filter field, enter a Berkeley Packet Filter (BPF) filter.
Select Start.

Results

The trace has been requested.
