12/4/2023 0 Comments Splunk search contains![]() ![]() Field names are case sensitive, but field values are not.If you are looking for fields, use the syntax.Several types of event processing occur during the search phase, such as search phase-field extraction, field aliasing, source type renaming, event type matching, etc.įor each event, the default fields and other indexed fields are extracted when indexing the data. The time span is beginning when a search is started and ending when the search is ended. Extract default fields and timestamps, and add transforms are also done at this moment. The data were analyzed in segments and incidents during index time. The time period from when the Splunk program obtains new data to when the data is written into an index. Extracted fieldsĪt index time and search time, the Splunk program extracts fields from the event data. ![]() Use the fields to write more custom searches to get back the unique events you want. Not every case has the same fields and values. Although the From field would only contain one email address, the To and Cc fields have one or more corresponding email addresses.įields are pairings of searchable names and values which distinguish one event from another. Some examples of fields are clientips for IP addresses that access your Web site, time for event timestamp, and host for the site domain name.Įmail address fields are one of the commonest examples of multivalue fields. A field can be multivalued that is to say, a field can have multiple values in a field in a single case. Sometimes an area is a value that has a fixed, delimited location on a line, or a pair of names and values, where each field name has a single meaning. Also, we are going to learn about extracted field, index time, search time, using the field for searching.įields occur in several ways in the system data. I would consider this a bug as it can really catch many by surprise.In this section, we are going to learn How to do field searching in the Splunk. I cannot find anything explicit in etc/system/defaults that can explain this spell even though "data:" appears in several entries in nf. In the above example, field "category" is just an accessary and not a necessary part of the demonstration.The spell-bound pattern can be prefixed by other patterns in this demonstration, "my ".The space character can be anything, even a newline. Only one of the values contains the pattern "data\s*:". ![]() | makeresults | eval category="fruits" | eval name="apple orange strawberry apricot my data : blueberry mango" | eval name=SPLIT(name, " ")Īpple,orange,strawberry,apricot,my data : blueberry,mango Stripped to the bare bones, the "data: spell", or compulsory mvzip syndrome, can be demonstrated with the following: This should get the display as you intended, even though desc_data becomes single-valued after this. Note: the newline must be entered as literal (Ctrl + "Enter" in search window), not as "\n", for example. Before I post additional diagnosis, let me demonstrate an idiotic workaround: add the following to the end This is an incredible find! I can confirm that, in a plain installation, multi-valued field with any value matching the regex "data\s*:" will be displayed in single line, as if there is a compulsory mvzip(). ![]()
