# Events Filters

You can apply filters to events in all interfaces:

- [Events List](https://docs.kloudfuse.com/platform/3.3.6/events-list/)
- [Events Time Series](https://docs.kloudfuse.com/platform/3.3.6/events-time-series/)
- [Events Top List](https://docs.kloudfuse.com/platform/3.3.6/events-top-list/)
- [Events Table](https://docs.kloudfuse.com/platform/3.3.6/events-table/)
- [Events Pie Chart](https://docs.kloudfuse.com/platform/3.3.6/events-pie-chart/)
- [Events Analytics](https://docs.kloudfuse.com/platform/3.3.6/events-analytics/)

Events use these filter categories:

## Filter Categories

1. **[level](https://docs.kloudfuse.com/platform/3.3.6/events-filters/#level)**: Filters on the state of the events: **_info_**, **_warning_**, or **_error_**.

2. **[source](https://docs.kloudfuse.com/platform/3.3.6/events-filters/#source)**: Filters on the source of the event, such as **_aws_**, **_kubernetes_**, **_container_**, **_System_**, and so on.

3. **[Labels](https://docs.kloudfuse.com/platform/3.3.6/events-filters/#label)**: Filters based on the observed system type, such as [Cloud](https://docs.kloudfuse.com/platform/3.3.6/events-filters/#cloud), [Kubernetes](https://docs.kloudfuse.com/platform/3.3.6/events-filters/#kubernetes), and [Additional](https://docs.kloudfuse.com/platform/3.3.6/events-filters/#additional).

4. **[Facets](https://docs.kloudfuse.com/platform/3.3.6/events-filters/#facet)**: Filters based on identified system-wide facets, such as **priority**, **host**, **id**, **event type**, **aggregation key**, and **message**.

## Level

In situations where you want to more closely examine one of the available levels in your Event stream, such as **_error_** conditions, follow these steps:

1. Hover your pointer over the **level** filter, and de-select the other level categories.

2. The chart displays only the currently selected level options.

## Source

To more closely examine one of the available sources in your Event stream, such as only **_System_** events, follow these steps:

1. Hover your pointer over the **source** filter, and de-select the other source categories.

2. The chart displays only the currently selected source options.

## Labels

Use the **Labels** in Kloudfuse to track and manage event data.

There are three primary Label groupings: [Cloud](https://docs.kloudfuse.com/platform/3.3.6/events-filters/#cloud), [Kubernetes](https://docs.kloudfuse.com/platform/3.3.6/events-filters/#kubernetes), and [Additional](https://docs.kloudfuse.com/platform/3.3.6/events-filters/#additional).

### Cloud

Includes [availability zone](https://docs.kloudfuse.com/platform/3.3.6/glossary/#availability-zone), awsRegion, aws_account, host, instance id, [instance type](https://docs.kloudfuse.com/platform/3.3.6/glossary/#instance-type), [project](https://docs.kloudfuse.com/platform/3.3.6/glossary/#project), region, and so on.

### Kubernetes

Includes [kube cluster name](https://docs.kloudfuse.com/platform/3.3.6/glossary/#kube-cluster-name), [kube container name](https://docs.kloudfuse.com/platform/3.3.6/glossary/#kube-container-name), [kube namespace](https://docs.kloudfuse.com/platform/3.3.6/glossary/#kube-namespace), [kube service](https://docs.kloudfuse.com/platform/3.3.6/glossary/#kube-service), and [pod name](https://docs.kloudfuse.com/platform/3.3.6/glossary/#pod-name).

### Additional

Includes filters based on custom labels and tags.
