Basic terms



• SaaS (Software as a Service)
  • Software-as-a-Service (SaaS) is a type of Cloud Computing that provides cloud applications and underlying IT infrastructure and platforms to end-users through an Internet browser.
• APM (Application Performance Management)
  • Solutions for monitoring and managing the performance and resource availability of software applications. APM provides the capabilities needed to detect and diagnose complex application performance issues to maintain expected service levels.
• Monitoring
  • Surffy’s NetFUNNEL is a solution (APM, Application Performance Management (Monitoring)) that monitors and manages the performance and service stability of applications (systems, application software). Users can check the real-time service status and use it to quickly check and analyze service issues.
• VWR (Virtual Waiting Room)
  • NetFUNNEL's VWR (Virtual Waiting Room) is a digital transaction management solution that monitors service performance experienced by end-users and ensures the best performance by controlling user transactions in touch with the service conditions.
  • It means NetFUNNEL's waiting rooms. NetFUNNEL is a service from the user's point of view that analyzes service processing performance by collecting the real-time user's perceived speed. End-users can check various information, such as the wait time to enter the service and the queue waiting in front of them, and customers can provide end-users with a waiting experience based on service fairness, such as inserting descriptions and brand logos in the waiting rooms.
  • During monitoring, the specialized traffic control system of NetFUNNEL VWR enables real-time control of problematic sections according to service conditions, so it is possible to prevent unexpected failures in advance.
• EUM (End-User Monitoring)
  • Managing the application user's experience information (access area, device, browser, traffic, etc.).

Monitoring terms



• Agent
  • An agent is an API call・response code that works to control the NetFUNNEL service on the system. When a load occurs in communication with the user terminal (browser, smartphone, tablet), it opens or closes the NetFUNNEL waiting rooms.
  • Support for Web, Android, iOS.
• Tenant
  • When a customer wants to use the SaaS service, it means a service environment designed only for the customer.
• Project
  • In NetFUNNEL, a project means a set of services and domains (segments) that customers and users encounter. A project is to manage multiple functions (segments) in groups.
  • e.g., For users who use the National Tax Service (e.g., Hometax) during the year-end tax settlement period, the Hometax service is a project. For NetFUNNEL users and administrators, one project is one administrative unit and one licensing unit.
• Project name: The project name displayed on the monitoring screen
• Project key: A unique project key used when the agent communicates with the NetFUNNEL server
• Segment
  • In NetFUNNEL, segment means various functions in the service that customers and users encounter. A group of functions (segments) is called a project. For NetFUNNEL users and administrators, a segment is a minimum unit that can be controlled by NetFUNNEL.
  • e.g., Each of these functions is a segment, such as income deduction inquiry, issuance, declaration preparation, and submission within a single project called the National Tax Service (Hometax).
• Segment name: Segment name displayed on the monitoring screen
• Segment key: A unique segment key used when the agent communicates with the NetFUNNEL server
• Domain
  • The customer’s site using NetFUNNEL. e.g., www.yoursite.com
• Service domain setting
  • NetFUNNEL communicates and controls traffic with only one domain set in the project within the customer’s site. This is a licensing policy to prevent abuse of multiple sites with one project. When operating multiple sites, it is a principle to configure multiple projects.
• Activation
  • Activating project
    • Activating a project in NetFUNNEL means that you want to start NetFUNNEL operation. The service visitors enter the customer system where NetFUNNEL is operating. A service visitors can only use the service as much as the number of limited inflow by NetFUNNEL, and next inflow are processed as NetFUNNEL waiting rooms containing waiting information.
  • Deactivating project
    • When deactivated, all projects are deactivated together with segments, and service users enter the customer system without going through NetFUNNEL. Even if the customer’s site is under load, it doesn’t wait for service visitors or display a NetFUNNEL waiting room.
      • In the case of the set URL, it doesn’t wait for service visitors, but in order to manage the service visitor who needs by-pass, the Key check library is planted in the WAS to respond only to the service visitor who requested through the NetFUNNEL Key (ticket).
• Access mode
  • Allow or block inflow of all service visitors through NetFUNNEL control. If the user block the access mode, the inflow into the customer system is blocked.
  • Allow
    • Allows NetFUNNEL service to the set URL. Traffic can be controlled through NetFUNNEL when a load on the customer’s site occurs.
  • Block
    • In (the case of a) blocked URL, NetFUNNEL user can limit the service access with a warning notification.
    • e.g., In the case of a specific service opening time or service regular inspection, the service login is blocked before that time, and after that time, the service is allowed through unblocking.
• Bot Blocking
  • Detect service users using bots and block service access.
