1 DSView 3 Software Plug-in for Virtualization The DSView® 3 management software plug-in for Virtualization allows you to access and control virtual machines from the DSView 3 software. Supported unit types include VMware® VirtualCenters, ESX Servers and virtual machines, as well as Citrix® XenServersTM and virtual machines. You can launch a Virtual Network Computing (VNC), Remote Desktop (RDP), Secure Shell 2 (SSH) or VMware viewer session to supported virtual machines from a single point of access.
2 Technical Bulletin NOTE: (VMware only) If you do not need to access the VI Client on an attached ESX Server, you only need to connect the VirtualCenter to the network and then you can access any attached ESX Servers as well. Figure 1.1: DSView 3 Software System Configuration with a Connected Virtual Environment Table 1.

Virtual machine system requirements • A POSIX operating system (Linux or Solaris) with the Syslog enabled • Sun Java™ VM J2SE 1.
24 Technical Bulletin Configuring the Syslog The data logging client receives Syslog messages from a named pipe and forwards them to the DSView 3 Syslog server. To configure the Syslog: 1. From the virtual environment command line, log in as administrator or root. 2. Run the mkfifo command to create a fifo device: mkfifo -m 666 For example: mkfifo -m 666 /var/evt_pipe 3. Edit the /etc/syslog.
DSView® 3 Plug-in Virtualization Technical Bulletin 3. • DataLoggingClient.properties properties file • DataLoggingClient.sh shell script 25 Copy the exported data logging key file to the appropriate location on the virtual machine. a. Set the data logging key file mod to 700 using the following command: chmod 700 filename. The data logging key file is only readable by the owner. b.
26 Technical Bulletin Property Description dls.bufferSize Sets the size of the buffer (in bytes) used to receive and send data. Sets the max number of messages included in a packet. By default, the data logging dls.packetSize client attempts to get a number of messages before sending data to the DSView 3 software. Setting this number to 1 would decrease the performance and increase the network traffic. Max wait time-out in milliseconds. The data logging client waits this amount of time dls.

DSView® 3 Plug-in Virtualization Technical Bulletin Events 29 Events * If you use the virtual environment to add or remove a virtual machine, the corresponding events are logged and the virtual environment and DSView 3 software are automatically synchronized.. ** This event is initiated from the DSView 3 software and does not have an equivalent in the virtual environment. This event will be recorded if: Use DSView User Credentials for Operations was not selected in the Add Unit Wizard.
30 Technical Bulletin Events In some cases, the virtual environment may be unresponsive and unable to receive tasks from the DSView 3 server. The DSView 3 Events list will indicate that the task was submitted successfully by the DSView 3 server even if the virtual environment did not receive it. To troubleshoot an unresponsive virtual environment, see the documentation included with the virtual environment. DSView 3 zones - virtualization restrictions DSView 3 software version 3.5.
DSView® 3 Plug-in Virtualization Technical Bulletin 31 NOTE: Since cross-zone information is not shown, details regarding which zone and which units conflicted is not sent or show to sub-level zones or users. Reconciling virtual environment units A unit cannot reconcile (for example, perform a resync or auto-topology operation) if the unit or any part of the unit (such as a virtual machine hosted on a hypervisor server) has already been added to a zone in the DSView 3 software.
