NetScaler is an incredibly versatile networking appliance. The amount of features it contains combined with the speed and reliability it provides while performing tasks is truly incredible. Thousands of companies around the world depend on NetScaler every day for delivery of business-critical workloads.

However, as with any technology, problems can and do occur.

Appliances can exhibit disruptions for a variety of reasons including both software and hardware failures. The most important thing in these scenarios is to prevent the issue from impacting users, or worse, developing into an outage. By enabling “Call Home” on NetScaler, you can go a long way to assist in this area.

Think of Call Home As An Insurance Policy

Hopefully, you never have to use Call Home. Though, at the same time, be glad you have it and sleep easier at night. For, once enabled, Call Home can:

  • Continuously monitor the appliance for error conditions of system process crashes (warm restarts) as well as hardware issues (e.g. hard drive and PSU failures).
  • Automatically collect and upload a diagnostic data bundle to the Citrix servers when an error condition occurs
  • Allow Citrix Technical Support to review diagnostic data bundles, as needed or at your request by contacting Support directly and we’ll already have the necessary details to dig into the issue.
  • Continually help improve the product in areas such as manageability, quality, the diagnostic data collected can be used as a feedback mechanism to improve NetScaler

I’m also pleased to announce that we are further enhancing the Call Home capabilities for NetScaler over the coming releases. Additionally, we plan to bring Call Home to other products in the not-too-distant future as well (CloudBridge 7.4 Beta includes Call Home among other exciting features. You can read more about the pre-release at /blogs/2015/02/12/try-programmability-and-hop-by-hop-visibility-with-cloudbridge-7-4-beta/).

We always enjoy hearing success stories from customers as well as feedback on how we can make our solutions better. Call Home functionality leverages the Citrix Insight Services platform ( Feel free to write to us anytime at Perhaps you’re already a Call Home user and if so, great! We’d love to hear how it’s helped you.

Until next time…
