Traffic Monitoring with Trisul
Traffic monitoring is the central task of Trisul. Out of the box, Trisul measures over 120 parameters about 16 different "things" such as Applications, Hosts, VLAN, MAC, etc. A "Counter Group": Traffic metering concepts is the key concept you need to know about in Traffic Monitoring with Trisul.

📄️ Name Resolution
You can assign a user friendly name for any type of item.
📄️ Custom Key Monitors
Custom Key Monitors allow you to monitor a set of key items in real time, irrespective of whether they show up in the toppers list or not. You can think of them as subset of a counter group that is “special” to you. For example, the IP (Hosts counter group) 192.168.14.16 is our internal build server, so we want to monitor it separately, generate reports for it separately, even though we may have thousands of other hosts.

Traffic Analysis Features
Real Time
You can monitor any metric in real time using Real time stabbers. This helps with troubleshooting and real time tracking of developing situations.
Historical Analysis
Use retro analysis tools, long term traffic charts, monthly usage reports and other tools for historical analysis. Trisul does not summarize or roll up any old data.
Data Acquisition Methods
Packet Capture
The default mode. Trisul does all its analytics by directly capturing packets from the network. Learn how to capture packets for Trisul NSM.
NetFlow
Can also accept Netflow v5, v9, SFLOW, and IPFIX instead of packets. This is a powerful low-cost way to gain total visibility into your internal network traffic without a TAP and Probe rollout with packet capture techniques.
Task List
Jump to common network analysis tasks
- Find out which flows caused a traffic pattern
- View flow activity of a particular host or port in real time
- Jump from alerts to flows that caused them
- Set up flow trackers to analyze specific activity
- Investigate past activity
- Enable metering which depend on flows not packets
- Optimize full content storage (eg, store only first 1M of each flow)
