Recently I published a blog post titled: Citrix is Slow, Or is it Really? In that article I briefly mentioned using a product such as Goliath Performance Monitor. If you have XenApp or XenDesktop 7.x in your environment, you may rely on Citrix Director for monitoring and troubleshooting. If so, I’m sorry for you. It has been my experience that Director can miss quite a lot. At least in version 7.9 and earlier, which is what I have used the most. If I could put a value on the time I have spent over the last 6 months alone troubleshooting slowness issues which Director couldn’t help with, it would likely pay for a good monitoring product such as this two times over!
