We are working on a new blog post for NextHop on monitoring an OCS 2007 R2 deployment with Group Chat. One thing I wanted to put here was an illustration of the behaviors with the # of clients, the number of contacts or channel members and the impact of multiple open channels, you knew you could undock a channel right? Let me also note that the only real change with Lync is that it defaults to a polling interval of every 5 minutes by default instead of the 2 minutes of R2. 2277375 documents the change made in Group Chat CU6.
In the table above I want to call out a few items:
Row 4 states the polling of once every 2 minutes, this is the 28.8 value in columns C, D and E. Column B is illustrating a lower value of 14 which is approximately every 4 minutes. Notice how the polling of 20000 users with this rate compares to 3000 users who have fewer contacts but have 7 open channels at one time.
I share this information for a few reasons
I will update this post when the NextHop article is published.
ps – While I feel comfortable with what I blog about personally here and what I contribute to on NextHop, the addition of content on the Technet Wiki is something I worry about causing fragmentation. If you have thoughts, feedback or comments about the experience please let me know as the goal is to increase the value of content, not to increase the number of places.
