EMS 事件日志
- EMS 事件日志 事件将显示类似以下内容：
[node1: env_mgr: monitor.rtcLowPower:error]: Real-time clock battery is dangerously low. Replace it at the next available maintenance window.
[NODE1:monitor.chassisPower.degraded:warning]: Chassis power is degraded: RTC Battery is in WARN LOW state current voltage is 2774 mV, normal low is 2800 mV
[env_mgr: monitor.rtcHighPower:error]: Real-time clock battery voltage is above normal (P3.3V Batt is warning high (3307 mV).)
[node1: env_mgr: monitor.rtcWarnLowPower:error]: Real-time clock battery voltage is below normal (2880 mV).
传感器状态
- 3 伏电池传感器将显示警报状态：
