ITSI offers several advanced thresholding options you can leverage to more accurately and efficiently monitor your KPI data.Īdvanced thresholding lets you define and manage alert thresholds that are either time-based (static) or adaptive (self-adjusting). In both these situations, fixed, static values for thresholds might result in false alert reporting. Similarly, database workloads can change based purely on different time periods, such as weekday versus weekend. Under these conditions, a static alert threshold would prove to be inaccurate.įor example, the accurate alert thresholds for a database performing Online Transaction Process (OLTP) during the day and batch processing at night would be different. However, there are some monitoring situations in which different workloads for a KPI occur at regular and expected intervals. The simple solution to thresholding in IT Service Intelligence (ITSI) is to manually configure KPI thresholds. ITSI can't be installed on the same search head as IT Essentials Work (ITE Work) or Splunk Enterprise Security.Overview of advanced thresholding in ITSI Alongside IT Essentials Work or Splunk Enterprise Security To use CIM-based data models with ITSI, you have to manually install Splunk_SA_CIM. The ITSI installation package places the following directories in $SPLUNK_HOME/etc/apps: In the filter bar, enter Splunk Machine Learning Toolkit.In ITSI, click App: IT Service Intelligence > Manage Apps.Follow the steps in Install the Splunk Machine Learning Toolkit in the MLTK User Guide. Install the latest version of the Splunk MLTK.Install the Python for Scientific Computing add-on version 1.3 or later for your operating system from Splunkbase:.For more information, see Set up Predictive Analytics in ITSI. These add-ons are only required if you plan to use Predictive Analytics to predict service health scores. If you plan to use the ITSI Predictive Analytics capabilities, install the Splunk Machine Learning Toolkit (MLTK) and the Python for Scientific computing add-on. (Optional) Install required Predictive Analytics add-ons profile file in the etc directory and not the. If you want to set the PATH for all users, you need to log in as root in the bash shell and perform the above steps on the. If you install Java to a custom location, for example, when you install Oracle Java directly from Oracle's website, and neither PATH nor JAVA_HOME is set to the Java installation, you must add the bin bath of the JDK in $HOME/.bashrc. This is typically the case if you install the vendor Java packages in Linux or OS X. If the JAVA_HOME environment variable is set correctly to the base of the Java installation, or the java executable (or java.exe in Windows) can be found using the PATH environment variable, no additional action is required. Alternatively, you can download and install the latest version of Oracle Java 8-11 (JRE or JDK). On RHEL and Ubuntu Linux, you can install the vendor packages java-1.8.0-openjdk on RHEL Linux and openjdk-8-jdk on Ubuntu Linux. Install Java on all search heads running ITSI. You can install Java prior to or after installing ITSI but before you start running ITSI. IT Service Intelligence requires Java 8.x - 11.x to run anomaly detection and notable event management features. If this occurs, perform the workaround described in ITSI-4663. Using 32-bit JRE/JDK on ITSI version 4.3.x or later might cause the Rules Engine to fail with unclear errors in the search.log. Download the latest Splunk IT Service Intelligence product from Splunkbase.Deleting or renaming this user breaks ITSI installation and operation.Īt this time, you can't install ITSI from the Splunk Web interface. Your Splunk ITSI instance must include the default admin user.See Splunk Enterprise system requirements. Review the Splunk platform requirements for IT Service Intelligence.ITSI doesn't support installation using the app manager in Splunk Web or using the splunk install app command at the command line.įor information about what and where to install in various types of distributed environments, see Where to install IT Service Intelligence in a distributed environment. Install ITSI by extracting the ITSI installation package. Splunk Cloud customers must work with Support to coordinate access to the ITSI search head. In a single-instance deployment, a single Splunk Enterprise instance serves as both search head and indexer. Install Splunk IT Service Intelligence (ITSI) on an on-premises search head. Install Splunk IT Service Intelligence on a single instance
