  - Sensors
    The Sensors page lets you view all of the sensors that you have in your system.
  - Alerts
    The Alerts page shows all the latest alerts in the system. It lets you view the alerts in different modes, and carry out actions on the alerts.
  - 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.
  - Smart Polling in CMC
    The Smart Polling page gives you a read-only view of Smart Polling.
  - Arc in CMC
    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.

Link-events-specific commands reference


Syntax	`availability`
Parameters
Description	The availability command computes the percentage of time a link is UP. The computation is based on the link events UP and DOWN that are seen for the link.


Syntax	`availability_history <range>`
Parameters	range: the temporal window in milliseconds to use to group the link events
Description	The availability_history command computes the percentage of time a link is UP by grouping the link events into many buckets. Each bucket will include the events of the temporal window specified by the range parameter.


Syntax	`availability_history_month <months_back> <range>`
Parameters	months_back: number of months to go back in regards to the current month to group the link events range: the temporal window in seconds to use to group the link events
Description	The availability_history command computes the percentage of time a link is UP by grouping the link events into many buckets. Each bucket will include the events of the temporal window specified by the range and months parameters.
