# Available Filters in OpManager Reports

OpManager generates a wide variety of reports covering performance, availability, forecasting, and utilization metrics across network devices. With large volumes of data being collected from numerous sources over time, it becomes essential to **extract only the most relevant information** for effective analysis and decision-making. This is where **filters** come into play.

## Filters in Reports

Filters in OpManager reports allow users to **narrow down and customize** the dataset they wish to analyze. Instead of wading through all available data, users can **focus only on what matters most**—based on devices, time, site, or specific performance parameters.

## List of Available Filters and Their Uses

| Filter | Description |
|---|---|
| **Filter by** | View data for all devices or narrow it down to a specific *Business View* or *Logical Group*. |
| **Category** | Filter devices based on type, such as *Servers*, *Wireless*, *UCS*, *Printers*, etc. |
| **Period** | View data across defined time ranges like *Last 1 hour* to *Last 90 days*, or even *future periods* for forecasting reports. |
| **Time Window / Business Hour** | Focus on data within *working hours*, *custom business hours*, or *entire 24-hour windows*. |
| **View Records** | Display only the *Top N* or *Bottom N* records based on chosen metrics. |
| **Monitors** | Focus the report only on *specific performance monitors* (e.g., CPU, Memory, RTT). |
| **Devices** | Include data from only selected devices. |
| **Perf Group** | The [Perf Group](https://www.manageengine.com/network-monitoring/help/perf-group.html) is a collection of related performance monitors grouped together, useful for creating custom reports. Perf Group reports is available in few default reports as well. |
| **Value Types** | OpManager collects device performance data at regular intervals (detailed statistics) and aggregates it hourly using Minimum, Maximum, and Average value types. These value types help visualize metrics like lowest CPU usage, peak memory usage, and average disk I/O. |
| **Sites** (Enterprise Edition) | Filter reports for a specific *probe/site*. |
| **Customers** (MSP Edition) | Generate reports for a particular *customer*. |
| **Event type** | Event type allows users to select specific event categories to view. It helps in quickly isolating and analyzing relevant network events. |
