## Overview

Monitor Podman container resource utilization — CPU, memory, disk I/O, and network — via Linux cgroups.



This collector is only supported on the following platforms:

- Linux

This collector supports collecting metrics from multiple instances of this integration, including remote instances.


### Default Behavior

#### Auto-Detection

This integration doesn't support auto-detection.

#### Limits

The default configuration for this integration does not impose any limits on data collection.

#### Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.

## Setup


### Prerequisites

No action required.

### Configuration

#### Options



There are no configuration options.



#### via File

There is no configuration file.

##### Examples
There are no configuration examples.



## Alerts


The following alerts are available:

| Alert name  | On metric | Description |
|:------------|:----------|:------------|
| [ cgroup_10min_cpu_usage ](https://github.com/netdata/netdata/blob/master/src/health/health.d/cgroups.conf) | cgroup.cpu_limit | average cgroup CPU utilization over the last 10 minutes |
| [ cgroup_ram_in_use ](https://github.com/netdata/netdata/blob/master/src/health/health.d/cgroups.conf) | cgroup.mem_usage | cgroup memory utilization |
| [ cgroup_1m_received_packets_rate ](https://github.com/netdata/netdata/blob/master/src/health/health.d/cgroups.conf) | cgroup.net_packets | average number of packets received by the network interface ${label:device} over the last minute |
| [ cgroup_10s_received_packets_storm ](https://github.com/netdata/netdata/blob/master/src/health/health.d/cgroups.conf) | cgroup.net_packets | ratio of average number of received packets for the network interface ${label:device} over the last 10 seconds, compared to the rate over the last minute |


## Metrics

Metrics grouped by *scope*.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.



### Per cgroup
