# Look deeper with Metrics

We also have a robust Metrics engine that keeps a track of many important metrics throughout all test runs, with the ability to add custom metrics as well. The Metrics can then be visualized using the Metrics section on IoTIFY. Graphs can be generated with a multitude of filters to better understand how the system has been performing.

Here, you can select which metric you want to see from the drop-down here, then choose an aggregate function and the job you want the metrics for, and finally click on the Update Chart button to create the chart.

{% hint style="info" %}
We log certain metrics like message latency and sending latency by default for all simulation jobs. Additionally, you can also see the system metrics like the number of MQTT connects, total bytes sent via MQTT and more by the `System-wide Metrics` toggle.
