Keep track of your UPS systems with PRTG<\/strong><\/h3>\nIt comes unexpectedly, is annoying and almost every administrator has experienced it: a power outage. The reasons can be many and varied: an excavator cuts a critical electrical line, a distribution point is damaged, or a problem occurs in a power substation. In such cases, private households, data centers and also production facilities are affected. In the production sector in particular, dependence on information and communication technology systems has increased in recent years due to Industry 4.0 and the\u00a0Internet of Things (IoT)<\/a>.<\/p>\nDue to the increasing flood of data,\u00a0data center<\/a>\u00a0IT services and the often-associated SLAs (Service-Level-Agreements), are nowadays heavily dependent on keeping the power flowing steadily and without interruption. It is therefore essential to not only connect all devices that are important for emergency operation to the\u00a0UPS (Uninterruptible Power Supply)<\/a>\u00a0systems correctly, but also have them evenly distributed.<\/p>\nIT infrastructure dependencies<\/h3>\n
Uptime in the case of a power failure cannot be guaranteed if, for example, all components are connected, but the\u00a0storage system<\/a>\u00a0is connected to a UPS that is under-powered. The obvious consequence:\u00a0all servers are running<\/a>, but at a certain point in time they can no longer access data because the capacity of the UPS is not sufficient to bridge the time until the standby power system has taken over or all servers have been shut down.<\/p>\nThe larger the server network, the more important it is to take a close look at the emergency power supply.\u00a0Air conditioning systems, access systems and alarm systems should also not be neglected.<\/a>\u00a0When the temperature in the data center rises, this can significantly impair operation or lead to additional failures, despite sufficient power supply to the IT infrastructure.<\/p>\nMonitoring UPS systems<\/h3>\n
PRTG offers\u00a0various possibilities<\/a>\u00a0to monitor your UPS systems. In addition to manufacturer-specific sensors, you can integrate almost any UPS into the monitoring concept using SNMP. User-defined sensors additionally allow a deeper insight beyond the standard values. Depending on your UPS, PRTG can monitor the following values, among others:<\/p>\n\n- UPS Input Voltage<\/li>\n
- UPS Output Voltage<\/li>\n
- UPS Time on Battery<\/li>\n
- UPS Battery Status<\/li>\n
- UPS Battery Time Remaining<\/li>\n
- Uptime<\/li>\n
- …<\/li>\n<\/ul>\n

<\/span><\/div>\nNotifications in case of power failure or voltage fluctuations<\/h3>\n
Even in the case of short power outages that can occur at night or voltage fluctuations, PRTG reliably informs you through\u00a0individual notifications<\/a>. Especially for smaller field offices, where for example only one server is operated with a UPS system, a power failure can quickly go unnoticed. To prevent this, you can create a notification when the value of the “Time on Battery” channel is greater than ‘0’. To do this, click on the “UPS Time on Battery” channel in the\u00a0UPS Health Sensor\u00a0and enter a value greater than ‘0’ for “Upper Error Limit(s)”:<\/p>\n![](\"https:\/\/asdafrica.com\/wp-content\/uploads\/2021\/08\/UPS-Time-on-Battery.png\" "\\"UPS")
<\/span><\/div>\n <\/p>\n
In the next step you define the notification. To do this, click on “Notification Triggers<\/strong>” –> “Add State Trigger<\/strong>” and define the notification individually according to your needs:<\/p>\n![](\"https:\/\/asdafrica.com\/wp-content\/uploads\/2021\/08\/Notification-Trigger-UPS-monitoring.png\" "\\"Notification")
<\/span><\/div>\nAnalogous to this example, you can also be notified of voltage fluctuations.<\/p>\n
Load testing and maintenance are indispensable<\/h3>\n
In order to be prepared for an emergency and to be able to look into the future with confidence, regular load tests are vital. In this way, it can be definitively determined whether the\u00a0UPS systems and their configuration<\/a>\u00a0can continue to supply the systems with power for a defined period of time in the event of a power failure. In this way, both function and performance can be checked under real conditions. Regular tests also ensure routine in the event of an emergency and reveal any weak points. However, maintenance of the systems should also be carried out regularly by qualified personnel to avoid technical problems.<\/p>\n
