# nfacct.plugin
`nfacct.plugin` collects Netfilter statistics.
## Prerequisites
1. install `libmnl-dev` and `libnetfilter_acct-dev` using the package manager of your system.
2. re-install netdata from source. The installer will detect that the required libraries are now available and will also build netdata.plugin.
Keep in mind that NFACCT requires root access, so the plugin is setuid to root.
## Charts
The plugin provides Netfilter connection tracker statistics and nfacct packet and bandwidth accounting:
Connection tracker:
1. Connections.
2. Changes.
3. Expectations.
4. Errors.
5. Searches.
Netfilter accounting:
1. Packets.
2. Bandwidth.
## Configuration
If you need to disable NFACCT for netdata, edit /etc/netdata/netdata.conf and set:
```
[plugins]
nfacct = no
```
## Debugging
You can run the plugin by hand:
```
sudo /usr/libexec/netdata/plugins.d/nfacct.plugin 1 debug
```
You will get verbose output on what the plugin does.
