Overview
The FTOS diagnostics and debugging features are a proactive approach to maximizing system uptime and
reducing meantime to resolution (MTTR) when a problem occurs. This feature set includes a combination
of proactive and reactive components designed to alert the user to network events, automatically collect
information on the event, and allow the user to collect diagnostic information from the system.
• Proactive component
• The system health check detects, reports, and takes action on an error in real time.
• When an automatic corrective action is not appropriate, the system health check reports the
detected anomaly, in real time, via a syslog message and/or SNMP.
• Reactive component
• When an error condition is asserted, appropriate show and debug commands are available to assist
in identifying the condition as well as rapid fault isolation.
• Trace files are continuously written by various FTOS software tasks to report hardware and
software events and status information.
• Core dumps provide key information in files that are saved in case of an application or kernel
crash.
