Juniper health check commands
show chassis alarms or show system alarms - check active alarms on device (note: lack of alarms does NOT mean there are no issues)
show chassis cluster status - check which node is active and which is standby (node 0 = FW01 and node 1 = FW02)
show chassis cluster information - check failover history, when most recent failovers occurred
show chassis environment - check status of hardware components (OK = good, Check = there is an issue, Absent = no component in slot)
show log messages or show log messages | match <filter> - check logs
show chassis routing-engine - check routing engines, utilization
show chassis hardware detail - check hardware information (serial numbers, etc.)
show chassis fpc - check memory utilization, CPU utilization and temp of slots
show chassis fpc pic-status - check FPC PIC health
