Aktuelle User Verbindungen eines Lync Registrar Pool abfragen

Um die aktuellen User Verbindungen zu einem Lync Registrar Pool abzufragen, wird ein entsprechender PS Script benötigt.

Vielen Dank an Mahmoud Badran. Der PS Script Connections.ps1 ermöglicht es durch verschiedene Parameter können alle Verbindungen des Registrar Pools oder aber auch einzelne User Abgefragt werden.

# Connections.ps1
#
# Program to pull Lync connection information.
# This program will pull complete information across all
# frontend servers in a pool.  It can also be used to find
# specific connection information on an individual user by
# supplying the user’s sip address.  The parameter for
# the pool to access for connection information can be
# pre-populated so it doesn’t have to be passed on the command line.
# Also it List all the connected Users.
#
# ACKNOWLEDGEMENT: This program’s database connection information
#                  was originally taken from the “List Connections
#                  to Registrar Pools” submitted by Scott Stubberfield
#                  and Nick Smith from Microsoft to the Lync 2010
#                  PowerShell blog
#                  (http://blogs.technet.com/b/csps/) on June 10, 2010.
#
# NOTE: In order to gain remote access to each frontend server’s
#       RTCLOCAL database where connection information is found,
#       you need to open the local firewall for port 1434.
#       Also, need to go into the SQL Server Configuration Manager
#       and for RTCLOCAL, enable named pipes and restart the SQL
#       service for the named pipes to take effect.
#
#       Port 1434 is required in order to make the connection to
#       the named instance RTCLOCAL on the remote machines.

NAME
Connections.ps1

SYNOPSIS
Returns current connection count for all frontend servers in a given pool
including a breakdown of connection by client, frontend server and users.

It can also be used to return connection information on an individual user.

SYNTAX
Connections.ps1 [-Pool <PoolFQDN>] [-SIPAddr] [-FilePath] [-help]

DESCRIPTION
This program will return a connection count for a given pool.  The program
can be edited to set a default pool.  You will also be able to get
information on an individual user by providing the users SamAccountName.
As well as listing all the connected users to the default pool.

EXAMPLES

————————– EXAMPLE 1 ————————–

C:\PS>connections.ps1

Description
———–
Returns information on all connections on all frontend servers in the
default pool that has been hard-coded into the program.

————————– EXAMPLE 2 ————————–

C:\PS>connections.ps1 -Pool alternate.pool.fqdn

Description
———–
Returns information on all connections on all frontend servers in the
pool given with the pool parameter.

————————– EXAMPLE 3 ————————–

C:\PS>connections.ps1 -SIPAddr userid@sip.domain

Description
———–
Returns all connection information for the given user including which
frontend server connected to, how many connections and which clients
connected with.

————————– EXAMPLE 4 ————————–

C:\PS>connections.ps1 -filepath c:\path\to\file\filename.csv

Description
———–
Returns information on all connections on all frontend servers in the
default pool that has been hard-coded into the program and in addition
writes out all the raw connection information into the filename specified.
