While this technique is useful and often sufficient, leveraging the new DensityFunction algorithm in the MLTK provides several advantages (take a look at this blog post on the Splunk Machine Learning Toolkit 4.2 for a deeper dive). These searches currently use Splunk's computational capabilities to calculate the standard deviation for a set of data points and then look for values that exceed some multiple of that number. Splunk Enterprise Security Content Update (ESCU) contains several searches that look for spikes in various data that may be indicative of malicious activity in your environment. There are many cases in which identifying these anomalies is useful in a security context. The implementation of this algorithm in the MLTK means that we can now leverage machine learning (ML) techniques for identifying outliers in security-related data. It can help you identify anomalous values for a particular data set. This algorithm is used to determine where values of a data set are expected to fall, based on historical values. Optional: To remove the Grafana repository: sudo rm -i /etc/apt//grafana.Splunk recently released the 4.2 version of the Machine Learning Toolkit (MLTK), featuring a new algorithm-the probability density function. To uninstall Grafana Enterprise: sudo apt-get remove grafana-enterprise To uninstall Grafana OSS: sudo apt-get remove grafana If you configured Grafana to run with init.d, stop the init.d service for Grafana server: sudo service grafana-server stop If you configured Grafana to run with systemd, stop the systemd servivce for Grafana server: sudo systemctl stop grafana-server To uninstall Grafana, run the following commands in a terminal window: Copy and paste the code from the download page into your command line and run.Ĭomplete any of the following steps to uninstall Grafana.Depending on which system you are running, click the Linux or ARM tab on the download page.Open Source: This version is functionally identical to the Enterprise version, but you will need to download the Enterprise version if you want Enterprise features.It is functionally identical to the open source version, but includes features you can unlock with a license, if you so choose. Enterprise: This is the recommended version.If you want to install a nightly build, click Nightly Builds and then select a version. The Version field displays only tagged releases.The most recent Grafana version is selected by default.Select the Grafana version you want to install.If you choose not to install Grafana using APT, you can download and install Grafana using the deb package or as a standalone binary.Ĭomplete the following steps to install Grafana using DEB or the standalone binaries: Install Grafana using a deb package or as a standalone binary To install Grafana Enterprise, run the following command: # Installs the latest Enterprise release: To install Grafana OSS, run the following command: # Installs the latest OSS release: Run the following command to update the list of available packages: # Updates the list of available packages To add a repository for beta releases, run the following command: echo "deb beta main" | sudo tee -a /etc/apt//grafana.list To add a repository for stable releases, run the following command: echo "deb stable main" | sudo tee -a /etc/apt//grafana.list Sudo wget -q -O /usr/share/keyrings/grafana.key Sudo apt-get install -y software-properties-common wget To install required packages and download the Grafana repository signing key, run the following commands: sudo apt-get install -y apt-transport-https You can also upgrade to the full Enterprise feature set, which has support for Enterprise plugins.Ĭomplete the following steps to install Grafana from the APT repository: It is available for free and includes all the features of the OSS edition. Note: Grafana Enterprise is the recommended and default edition.
