Project: Netdata (Observability and Analysis / Observability)
File: UPDATE.md

By default, the Netdata Agent automatically updates with the latest nightly or stable version depending on which you installed. If you opted out of automatic updates, you need to update your Netdata Agent to the latest nightly or stable version. You can also . Looking to reinstall the Netdata Agent to enable a feature, update an Agent that cannot update automatically, or troubleshoot an error during the installation process? See our for reinstallation steps. Before you update the Netdata Agent, check to see if your Netdata Agent is already up-to-date by clicking on the update icon in the local Agent dashboard's top navigation. This modal informs you whether your Agent needs an update or not. The exact update method to use depends on the install type: Installs with an install type of 'custom' usually indicate installing a third-party package through the system package manager. To update these installs, you should update the package just like you would any other package on your system. Installs with an install type starting with `binpkg` or ending with `build` or `static` can be updated using our . Installs with an install type of 'oci' were created from our official Docker images, and should be updated using our update procedure. macOS users should check . Manually built installs should check . Starting with netdata v1.33.0, you can use Netdata itself to determine the installation type by running: ```bash netdata -W buildinfo | grep -E 'Installation Type|Install type:' ``` The following table contains all possible installation types: | Installation-type | Description | |--|-| | binpkg-rpm | RPM-based native packages shipped from Netdata's repos. | | binpkg-deb | DEB-based native packages shipped from Netdata's repos. | | kickstart-build | Build from source with the kickstart script's `--build-only` option. | | kickstart-static | Installed the static builds, shipped from netdata via the kickstart script's (option: `--static-only`). | | manual-static-ARCH | Manually installed static Agent binaries by downloading archives from GitHub and installing them manually. Offline installations are part of this category. | | legacy-build | Used for pre-existing kickstart.sh or netdata-installer.sh installations. This exist because we cannot determine how the install originally happened. | | legacy-static | Same as legacy-build, but for static installs. | | oci | Installed using official Docker images from Netdata, though not necessarily running on Docker | | custom | Anything not covered by the other identifiers, including manual builds, manually running netdata-installer.sh, and third-party packages (community). | | Unknown | Same as

| If you are using an older version of Netdata, or the above command produces no output, you can run our one-line installation script in dry-run mode to attempt to determine what method to use to update by running the following command: ```bash wget -O /tmp/netdata-kickstart.sh https://get.netdata.cloud/kickstart.sh && sh /tmp/netdata-kickstart.sh --dry-run ``` Note that if you installed Netdata using an installation prefix, you will need to add an `--install-prefix` option specifying that prefix to make sure it finds the existing install. If you see a line starting with ` Would attempt to update existing installation by running the updater script located at:`, then our will work for you. Otherwise, it should either indicate that the installation type is not supported (which probably means you either have a `custom` install or built Netdata manually) or indicate that it would create a new install (which means that you either used a non-standard install path, or that you dont actually have Netdata installed). In most cases, you can update netdata using our one-line installation script. This script will automatically run the update script that was installed as part of the initial install (even if you disabled automatic updates) and preserve the existing install options you specified. If you installed Netdata using an installation prefix, you will need to add an `--install-prefix` option specifying that prefix to this command to make sure it finds Netdata. ```bash wget -O /tmp/netdata-kickstart.sh https://get.netdata.cloud/kickstart.sh && sh /tmp/netdata-kickstart.sh ``` The above command is known not to work with binpkg type installs for stable releases with a version number of v1.33.1 or earlier, and nightly builds with a version number of v1.33.1-93 or earlier. If you have such a system, the above command will report that it found an existing install, and then issue a warning about not being able to find the updater script. On such installs, you can update Netdata using your distribution package manager. The update process outlined above suffers from the same issues that installing on hosts without IPv4 connectivity does, and requires similar workarounds. For more details check [the explanation in our install documentation](https://github.com/netdata/netdata/blob/master/packaging/installer/README.md#installs-on-hosts-without-ipv4-connectivity). If the above command fails, you can [reinstall Netdata](https://github.com/netdata/netdata/blob/master/packaging/installer/REINSTALL.md#one-line-installer-script-kickstartsh) to get the latest version. This also preserves your in `netdata.conf` or other files just like updating normally would, though you will need to specify any installation options you used originally again. Docker-based installations do not update automatically. To update an Netdata Agent running in a Docker container, you must pull the , stop and remove the container, and re-create it using the latest image. First, pull the latest version of the image. ```bash docker pull netdata/netdata:latest ``` Next, to stop and remove any containers using the `netdata/netdata` image. Replace `netdata` if you changed it from the

```bash docker stop netdata docker rm netdata ``` You can now re-create your Netdata container using the `docker` command or a `docker-compose.yml` file. See our [Docker installation instructions](https://github.com/netdata/netdata/blob/master/packaging/docker/README.md#create-a-new-netdata-agent-container) for details. If you installed Netdata on your macOS system using Homebrew, you can explicitly request an update: ```bash brew upgrade netdata ``` Homebrew downloads the latest Netdata via the , ensures all dependencies are met, and updates Netdata via reinstallation. If you instead installed Netdata using our one-line installation script, you can use our [regular update instructions](#updates-for-most-systems) to update Netdata. If you installed , you can run that installer again to update your agent. First, run our automatic requirements installer, which works on many Linux distributions, to ensure your system has the dependencies necessary for new features. ```bash bash <(curl -sSL https://raw.githubusercontent.com/netdata/netdata/master/packaging/installer/install-required-packages.sh) ``` Navigate to the directory where you first cloned the Netdata repository, pull the latest source code, and run `netdata-install.sh` again. This process compiles Netdata with the latest source code and updates it via reinstallation. ```bash cd /path/to/netdata/git git pull origin master sudo ./netdata-installer.sh ``` If you installed Netdata with any optional parameters, such as `--no-updates` to disable automatic updates, and want to retain those settings, you need to set them again during this process. Starting with Netdata v1.34.0, you can easily enable or disable automatic updates on an existing installation using the updater script. For most installs on Linux, you can enable auto-updates with: ```bash /usr/libexec/netdata/netdata-updater.sh --enable-auto-updates ``` and disable them with: ```bash /usr/libexec/netdata/netdata-updater.sh --disable-auto-updates ``` For static installs, instead use: ```bash /opt/netdata/usr/libexec/netdata/netdata-updater.sh --enable-auto-updates ``` and: ```bash /opt/netdata/usr/libexec/netdata/netdata-updater.sh --disable-auto-updates ``` Starting with v1.40.0, the `netdata-updater.sh` script supports a config file called `netdata-updater.conf`, located in the same directory as the main `netdata.conf` file. This file uses POSIX shell script syntax to define variables that are used by the updater. This configuration file can be edited [using our `edit-config` script](https://github.com/netdata/netdata/blob/master/docs/netdata-agent/configuration/README.md). The following configuration options are currently supported: `NETDATAUPDATERJITTER`: Sets an upper limit in seconds on the random delay in the updater script when running as a scheduled task. This random delay helps avoid issues resulting from too many nodes trying to reconnect to the Cloud at the same time. The default value is 3600, which corresponds to one hour. Most users should not ever need to change this. `NETDATAMAJORVERSION_UPDATES`: If set to a value other than 0, then new major versions will be installed without user confirmation. Must be set to a non-zero value for automated updates to install new major versions. `NETDATANOSYSTEMD_JOURNAL`: If set to a value other than 0, skip attempting to install the `netdata-plugin-systemd-journal` package on supported systems on update. This optional package will be installed by default on supported systems by the updater if this option is not set. Only affects systems using native packages.
