Vietnamese Let’s face it, virtualization technologies aren’t exactly ‘plug & play’.
Even the simplest virtualization deployment touches almost every IT discipline and department – from networking and security to data centers, desktops and storage.
That’s why smart, well-informed administrators are so important to the success of every Citrix deployment.
It’s also why we took aside some of our top support engineers and asked them to share their insider tips – little things that most administrators may not know about but that can really make your lives easier.
We got lots of excellent tips for a whole range of Citrix products. And we collected them in a free guide called Secrets of the Citrix Support Ninjas.
Here’s a taste of the kinds of things our support ninjas thought you’d benefit from:
For XenApp
“Use the Citrix Scout tool to collect logs and CDF traces from selected computers. Citrix Scout is also used in conjunction with Citrix Auto Support to help resolve known issues.”
David McGeough
“Wondering if that print driver will work with XenApp? Use StressPrinters to get the answer!”
Nicholas Vasille
For XenDesktop
“You can quickly and easily optimize the user experience on XenApp & XenDesktop with the help and recommendations of HDX Monitor.”
Michael Ryan
“To view successful and failed connections over the past 48 hours, try the tool Get-BrokerConnectionLog.”
Rene Alfonso
For NetScaler
“While taking a nstrace, set the packet size to zero to collect the complete payload.”
Durga Kiran Bolagani
“Learn to troubleshoot in the command-line interface.
You see more information as a result of one command instead of several clicks in the GUI.”
An example: Show service <servicename> gives you ALL the service information, AND the monitor, AND the last monitor status.”
Ronan O’Brien
For XenServer
“Always run a metadata backup before any significant modification to the pool, such as a hotfix installation or upgrade.”
Corin Goodier
“If you’re using OVS, capturing traces on the bond won’t work. Use tcpdump on the two physical interfaces.If you’re using something like eth0 and eth1, try:
tcpdump -i eth0 -s 0 -w /tmp/eth0.pcap &
tcpdump -I eth1 -s 0 -w /tmp/eth1.pcap &
Then, when you’re done:
fg then ctrl+c to end the first, and again to end the second”
Gareth O’Brien
Come and get it.
There are a lot more tips in the Secrets of the Citrix Support Ninjas eBook – so download it and take a look.
We’ve also put in some screenshots of the Citrix Auto Support tool in case you don’t know about it yet. Our support ninjas use Citrix Auto Support every day to diagnose customers’ log files and take a quick snapshot of their environments.
So we’ve made it available to all customers for free. The tool reads your log files from Xen Desktop, XenServer, NetScaler and now XenApp too – giving you a really good report on any issues and their fixes. Do give it a go.
