Synthetic Indicators perform simple math on multiple metrics collected from a single monitored device. For example, when polling interfaces, you may view in bytes and out bytes, but polling total bytes is not an option. To address this visibility gap, SevOne provides Synthetic Indicators that allow you to combine, report, and alert on the sum of those data sources. This provides a real-time view of total bytes consumed for a particular link even though this value does not exist in the MIB of the target device. With this new Synthetic Indicator modeled, you receive alerts any time your capacity utilization exceeds a defined percent or deviates from “normal” baseline performance for your environment.
You can also use Synthetic Indicators to monitor and compare ratios of items such as, connections succeeded vs. connections failed or packets sent vs. errors received. For example, you can compare how many packets were transmitted in the past minute and how many errors were generated. If 5% of all packets pushed are resulting in error, you know there is an issue to address.
In essence, Synthetic Indicators allow you to create new KPIs that do not currently exist on the device.
