📄️ Cardinality Counter
A cardinality counter is a metric that measures or estimates the number of unique elements observed within a dataset, traffic stream, or monitoring interval.
📄️ CDR
A CDR (Call Detail Record) is a structured log that captures metadata about a communication session such as participants, timestamps, duration, routing, and usage information. CDRs are widely used in telecom systems for billing, reporting, auditing, and operational analytics.
📄️ CGNAT
CGNAT (Carrier-Grade NAT) is a large-scale network address translation technique used by service providers to share public IPv4 addresses among many subscribers. It helps ISPs conserve IPv4 address space while continuing to provide Internet connectivity at scale.
📄️ CGNAT logging
CGNAT logging records the mapping between subscriber private IP addresses and translated public IPv4 addresses and ports assigned by Carrier-Grade NAT systems. These logs help ISPs support subscriber traceability, troubleshooting, compliance, and security investigations.
📄️ Cloud monitoring
Cloud monitoring is the process of observing cloud infrastructure, services, workloads, and traffic to track performance, availability, utilization, and security across cloud environments. Trisul supports cloud-oriented traffic visibility and flow analytics for hybrid and cloud-connected networks.
📄️ Congestion
Congestion is a network condition where traffic demand exceeds available forwarding or transmission capacity, causing queue buildup, increased latency, packet loss, jitter, or reduced throughput. It is one of the most common causes of degraded network performance.
📄️ Congestion detection
Congestion detection is the process of identifying when network demand approaches or exceeds available forwarding or transmission capacity. It helps operators detect bottlenecks, queue buildup, latency increases, and packet loss before severe service degradation occurs.
📄️ Context
A Trisul context is an isolated analytics domain within a Trisul deployment, with its own database, configuration, and processing state while sharing common administration and web management infrastructure.
📄️ Context menu
A context menu in network analytics is an interactive menu that provides investigation and navigation actions related to a selected traffic item, flow, host, alert, or metric. In Trisul, context menus support rapid drill-down and traffic investigation workflows.
📄️ Conversation view
Conversation view is a flow-analysis representation that combines traffic from both directions of a network exchange into a single conversational record for easier analysis and investigation.
📄️ Counter Group Tuning
Counter Group Tuning is the process of refining counter group configurations to improve the relevance, efficiency, and operational value of collected analytics.
📄️ Counter groups
A counter group is a logical collection of traffic counters in Trisul used to measure and analyze specific dimensions of network activity such as hosts, applications, protocols, interfaces, or traffic categories over time.
📄️ Country-Based Analytics
Country-Based Analytics is the process of analyzing network traffic, hosts, users, and communication patterns based on the geographic location associated with IP addresses.
📄️ Crosskey Tree
A Crosskey Tree is a Trisul analytics feature that allows analysts to navigate relationships between different traffic dimensions and pivot across related network entities during investigations.
📄️ Custom flow analytics
Custom flow analytics extends standard flow monitoring by applying user-defined classification, enrichment, tagging, and detection logic to flow data for organization-specific operational, security, and business analytics workflows.
📄️ Types of Counter Groups
Counter Groups can be organized into different types based on the analytical questions they are designed to answer, including Native, Crosskey, Keyset, Filter-Based, Stat-Based, and Rule-Based Counter Groups.
