SNMP UPS Event Monitor Reference Guide
notitie
Overview
The SNMP UPS Event Monitor utilizes SNMP to track and alert on critical health values of UPS (Uninterruptible Power Supply) devices, including battery status, charge levels, and temperature. This ensures that the UPS devices are operating effectively and are capable of providing backup power during power failures.
info
Use Cases
- Monitoring UPS battery status and operational health.
- Receiving alerts when UPS switches to battery power.
- Monitoring battery capacity and temperature for maintenance and safety.
Monitoring Options
SNMP Configuration
- SNMP Version: Select SNMPv1, SNMPv2, or SNMPv3 based on device support and configuration.
- Community: Enter the community string for SNMPv1 and SNMPv2c; typically "public" for read-only access.
- Port Number: Default is 161, customizable based on device configuration.
- Timeout: Set the response wait time, adjustable to suit network performance.
- Retries: Configure retry attempts to account for UDP's unreliable delivery.

Alerts
- Alert if the device cannot be contacted by SNMP: Notify if SNMP connections fail.
- Alert if the overall battery status is not 'normal': Trigger an alert for any status other than 'normal'.
- Alert if the UPS is running on battery: Get notified when the UPS switches to battery power.
- Alert if run time remaining is less than specified: Alert when remaining run time drops below a set threshold.
- Alert if battery capacity is below a specified percentage: Trigger an alert when battery capacity falls below a specified level.
- Alert based on battery temperature: Notify when battery temperature exceeds set parameters.
Authentication and Security
- SNMPv1 and SNMPv2c: Requires a community string.
- SNMPv3: Requires a username and detailed security parameters including authentication and encryption settings.
