# net.inet6.icmp6.stats
Plugin: freebsd.plugin
Module: net.inet6.icmp6.stats
## Overview
Collect information abou IPv6 ICMP
The plugin calls `sysctl` function to collect necessary data.
This collector is supported on all platforms.
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.
## 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 net.inet6.icmp6.stats instance
Collect IPv6 ICMP traffic statistics.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|:------|:----------|:----|
| ipv6.icmp | received, sent | messages/s |
| ipv6.icmpredir | received, sent | redirects/s |
| ipv6.icmperrors | InErrors, OutErrors, InCsumErrors, InDestUnreachs, InPktTooBigs, InTimeExcds, InParmProblems, OutDestUnreachs, OutTimeExcds, OutParmProblems | errors/s |
| ipv6.icmpechos | InEchos, OutEchos, InEchoReplies, OutEchoReplies | messages/s |
| ipv6.icmprouter | InSolicits, OutSolicits, InAdvertisements, OutAdvertisements | messages/s |
| ipv6.icmpneighbor | InSolicits, OutSolicits, InAdvertisements, OutAdvertisements | messages/s |
| ipv6.icmptypes | InType1, InType128, InType129, InType136, OutType1, OutType128, OutType129, OutType133, OutType135, OutType143 | messages/s |
## Alerts
There are no alerts configured by default for this integration.
## Setup
### Prerequisites
No action required.
### Configuration
#### File
The configuration file name for this integration is `netdata.conf`.
Configuration for this specific integration is located in the `[plugin:freebsd:net.inet6.icmp6.stats]` section within that file.
The file format is a modified INI syntax. The general structure is:
```ini
[section1]
option1 = some value
option2 = some other value
[section2]
option3 = some third value
```
You can edit the configuration file using the `edit-config` script from the
Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config netdata.conf
```
