# 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.
