analyze 10G network connection
Hello,
I analyze dot.net problems since about two years successfully with dynatrace solution.
At the moment we update our customers with 10Gbit/s networks and get more the problem that the network performance from win2012 servesr and hyperV server VMs over the hole the network have during a file transfer only a network performance of fluctuate 30MB/s up to 300MB/s. (by example backup last 18 hours an more!!).
Have anybody an idea how can I exactly analyze the bottlenek within the network and the the application. For network anylyze I use actual the Observer Vesion 16 from network instruments. I suspect a problem with the network driver of the HP network interface card, but I need a analyze tool to exacly define the bottleneck?
At my actual use case I have HP servers G8 with network 10G SFP interfaces HP534FLR SFP+ or HP534SLR SFP+ and use Cisco copper SFP cable to connect the Cisco 3750X switch-stack, the physical backup server is connected with a 4Gbit/s etherchannel LACP to the stack. The 10Gbit/s connection and the etherchannel 4Gbit/s seem to be all right, no errors occur. The bottleneck seems also to be between the 10G VM connection and the network server connection.
Thank You for Your help.
Best regards,

Hi Michael
dynaTrace probably doesn't go down as deep as you want. It captures network traffic by looking at web request and response size and also monitors key performance metrics of each network interface you have (reads, writes, ...). These values can be seen in the Infrastructure View.
If you want to go down to the network - including packet level analysis and optimization we have the right tool for you - it is our Data Center Real User Monitoring solution (DC-RUM for short). Check out the information on our website: http://www.compuware.com/en_us/application-performance-management/products/application-aware-network-monitoring.html plus some of the blog posts that show what this product can do for you: http://apmblog.compuware.com/2014/09/19/defending-network-performance-packet-level-detail/ or http://apmblog.compuware.com/2014/08/28/network-dive-deep-back-time-find-root-cause/ or http://apmblog.compuware.com/2014/08/21/understanding-application-performance-on-the-network-chattiness-application-windowing/
