Overview

The SNMP UPS Event Monitor watches key values on your UPS devices. It alerts based on battery status, charge level, battery temperature, and more to ensure the health of your UPS devices.

Use Cases

• Alerting about UPS battery status
• Getting alerts when a UPS switches to running on batteries
• Getting alerts about remaining battery capacity
• Receiving alerts based on battery temperatures

Monitoring Options

This event monitor provides the following options:

SNMP Version

Select the SNMP version that will be used to collect the inventory data. The best version to use will depend on how your network devices have been configured. Most devices support SNMPv1, but some may require SNMPv2 or SNMPv3.

Community

Enter the SNMP community string that will be used to connect. The community string is equivalent to a password. The default community string for read-only access is "public", so use this value if you are unsure of what community string your devices are configured to use. The community string is only required for SNMPv1 and SNMPv2c connections. SNMPv3 uses different authentication parameters.

Port Number

The standard port number for SNMP requests is 161. If your devices have been configured to use a different port, you can specify it here.

Timeout

The timeout tells the event monitor how long to wait for a response. The default value is best for almost all situations, but you can increase or decrease it if you choose.

Retries

Since SNMP runs on UDP packet, delivery and response are not guaranteed. For this reason, it is good practice to tell the event monitor to retry one or more times if it does not receive a response.

Alert with [Info/Warning/Error/Critical] if the device cannot be contacted by SNMP

Use this option to receive alerts if the device is unable to be contacted.

Alert with [Info/Warning/Error/Critical] if the overall battery status is not 'normal'

Use this option to be alerted if the battery status is anything other than 'normal'.

Alert with [Info/Warning/Error/Critical] if the UPS is running on battery

Use this option to find out when the UPS is running on battery.

Alert if run time remaining is less than a specified amount of time

This option lets you know if the remaining run time is less than the values you input.

Alert if battery capacity is lower than a specified percentage

Use this option to specify a threshold battery percentage that will trigger an alert if the UPS drops below that value.

Alert based on battery temperature

Use this option to be alerted when the UPS's battery temperature surpasses the values you specify.

Authentication and Security

For SNMPv1 and SNMPv2c, a community string for the device being monitored is required. For SNMPv3, a username and other SNMPv3 parameters are required.

Protocols

Data Points

This event monitor generates the following data points:

Data Point	Description
Battery Status	Set to one of unknown, batteryNormal, batteryLow, or batteryDepleted.
Running on Batteries	Set to 1 if it is and zero if not.
Battery Temperature	Measured in Celcius.
Battery Capacity	A percentage indicating the battery's charge level.
Run Time Remaining	How long in seconds until the battery runs out.
