Inventu FVTerm Web Terminal Emulation Help

An optional comma-separated file can be created and appended to as each user FVTerm session ends.  This file at this time is most relevant for TN5250 and TN3270 host sessions.  The best use of this is to identify where there may be performance issues in the network.  Any difference between the client response times and the host response times will indicate network and/or an issue in the Viewer Emulation service and the FVTerm application.

 

In tests on a moderately fast PC, moderately complex 3270 screens on the same system took approximately 1/100th of a second to flow through the Viewer Emulation Service and the FVTerm application--so, in general, the amount that the Client response time is greater than the server response time indicates network delay / latency (less 1/100 of a second for the Viewer latency).

 

In this file are the columns:

 

 

Timestamp

Date and Time that the session ended

Host

The hostname that the user was connected to.  This is the short host name ID, not the description provided in web.config and the connection tiles.

User

The userID, which depends on the setting connectIdentity -- the default is the user's IP address.  If windows security is active, this should be the user's windows / Active Directory ID

IP Address

The user's IP address as best obtained from HTTP header information

Device ID

The LU Name / DeviceID of the terminal session for TN5250 and TN3270 sessions

Session Duration

The session duration in minutes (need math to determine hours and minutes)

Avg Resp (Server)

Average response time, in seconds, at the server between enter key and buffer that unlocks the keyboard

Max Resp (Server)

Maximum response time, in seconds

Avg Resp (Client)

Average response time, in seconds at the web browser client, from an enter key through to a buffer is received unlocking the keyboard

Max Resp (Client)

The maximum response time in seconds at the client browser

Avg Page Render

Average time, in seconds that it took to render the HTML and ready the page for input (typically a few hundredths of a second)
