Install Netdata on pfSense

To install Netdata on pfSense, run the following commands (within a shell or under the Diagnostics/Command prompt within the pfSense web interface).

Note that the first four packages are downloaded from the pfSense repository for maintaining compatibility with pfSense, Netdata, Judy and Python are downloaded from the FreeBSD repository.

pkg install -y pkgconf bash e2fsprogs-libuuid libuv nano
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/Judy-1.0.5_2.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/py37-certifi-2020.4.5.1.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/py37-asn1crypto-1.3.0.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/py37-pycparser-2.19.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/py37-cffi-1.14.0.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/py37-six-1.14.0.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/py37-cryptography-2.6.1.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/py37-idna-2.8.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/py37-openssl-19.0.0.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/py37-pysocks-1.7.1.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/py37-urllib3-1.25.7,1.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/py37-yaml-5.2.txz
pkg add http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/netdata-1.20.0_3.txz

Note: If you receive a Not Found error during the last two commands above, you will either need to manually look in the repo folder for the latest available package and use its URL instead, or you can try manually changing the Netdata version in the URL to the latest version.

Note: On pfSense 2.4.5, Python version 3.7 may be installed by the system, in which case you should should not install Python from the FreeBSD repository as instructed above.

You must edit /usr/local/etc/netdata/netdata.conf and change bind to = 127.0.0.1 to bind to = 0.0.0.0.

To start Netdata manually, run service netdata onestart.

Warning: If you are using the apcupsd collector, you need to make sure that apcupsd is up before starting Netdata. Otherwise a infinitely running cat process triggered by the default activated apcuspd charts plugin will eat up CPU and RAM (/tmp/.netdata-charts.d-*/run-*). This also applies to OPNsense.

Visit the Netdata dashboard to confirm it's working: http://<pfsenseIP>:19999

To start Netdata automatically every boot, add service netdata onestart as a Shellcmd entry within the pfSense web interface under Services/Shellcmd. You'll need to install the Shellcmd package beforehand under System/Package Manager/Available Packages. The Shellcmd Type should be set to Shellcmd.
Alternatively more information can be found in https://doc.pfsense.org/index.php/Installing_FreeBSD_Packages, for achieving the same via the command line and scripts.

If you experience an issue with /usr/bin/install being absent in pfSense 2.3 or earlier, update pfSense or use a workaround from https://redmine.pfsense.org/issues/6643

Note: In pfSense, the Netdata configuration files are located under /usr/local/etc/netdata.
