Pulse is the Nutanix telemetry capability that securely transmits purpose-specific diagnostic and configuration data to Nutanix Support and Nutanix Insights. When Pulse and the associated Remote Diagnostics functionality are enabled, Nutanix can analyze cluster health information proactively, identify developing problems, collect relevant diagnostic information, and automate support workflows for critical conditions such as disk or DIMM failures.
Pulse is enabled on a per-cluster basis and uses an encrypted communication channel. It does not serve the same purpose as general event forwarding. Nutanix documents that Pulse does not collect guest-VM application data, user data, administrator credentials, or personally identifiable information. The transmitted system-level information is used to improve diagnosis and support responsiveness.
Syslog sends selected logs to a customer-controlled logging platform. SNMP provides monitoring information and traps to an external network-management system. SMTP enables email delivery for configured alerts. All three are valid monitoring integrations, but none sends the specialized diagnostic telemetry required for Nutanix’s proactive support service.
Therefore, the administrator should verify Pulse enablement, outbound connectivity, proxy configuration where applicable, and Remote Diagnostics status.
