Normalize alerts with correlation search templates in ITSI

IT Service Intelligence (ITSI) ships with several predefined correlation search templates to help you normalize alerts from common third-party systems. Leverage these searches when creating a correlation search to bring third-party alerts into ITSI and normalize them as notable events. For more information about correlation searches, see Overview of correlation searches in ITSI.

Prerequisites

Requirement	Description
ITSI role	You must have the write_itsi_correlation_search capability to create a correlation search. The itoa_admin and itoa_team_admin ITSI roles have this capabilities by default.
Ingest third-party data	You must be ingesting data from the corresponding third-party alerting system into Splunk Enterprise in order to normalize it in ITSI. Optionally, you can install the related Splunk add-on for that system. The table below lists the add-ons related to each search, if available.

Access correlation search templates

All third-party search templates are available within the correlation search creation workflow. To leverage a template, perform the following steps:

1. From the ITSI main menu, click Configuration > Correlation Searches.
2. Click Create New Search > Create Correlation Search.
3. Provide a name and description for the search.
4. For Search Type, choose Predefined.
5. Click Select a Search and choose from one of the predefined search templates described below.
6. Click Select an index and choose an index to use for the search.
7. Configure the rest of the correlation search to normalize the third-party alert fields. For instructions, see Ingest third-party alerts into ITSI.
