If you have Splunk Enterprise, this command saves search results to the specified CSV file on the local search head in the
$SPLUNK_HOME/var/run/splunk/csv directory. Updates to
$SPLUNK_HOME/var/run/*.csv using the
outputcsv command are not replicated across the cluster.
outputcsv [append=<bool>] [create_empty=<bool>] [dispatch=<bool>] [usexml=<bool>] [singlefile=<bool>] [<filename>]
- Syntax: append=<bool>
- Description: If
append=true, the command attempts to append to an existing CSV file, if the file exists. If the CSV file does not exist, a file is created. If there is an existing file that has a CSV header already, the command only emits the fields that are referenced by that header. The command cannot append to .gz files.
- Syntax: create_empty=<bool>
- Description: If
create_empty=trueand there are no results, creates a 0 length file. When
create_empty=false, no file is created and if
append=false, the file is deleted if it previously existed.
- Syntax: dispatch=<bool>
- Description: If set to true, refers to a file in the job directory in
- Syntax: <filename>
- Description: Specify the name of a CSV file to write the search results. This file should be located in the
$SPLUNK_HOME/var/run/splunk/csvdirectory. Directory separators are not permitted in the filename. Filenames cannot contain spaces. If no filename is specified, the command rewrites the contents of each result as a CSV row into the
_xmlfield. Otherwise the command writes into a file. The
.csvfile extension is appended to the filename if the filename has no file extension.
- Syntax: singlefile=<bool>
- Description: If
singlefile=trueand the output spans multiple files, collapses the output into a single file.
- Syntax: usexml=<bool>
- Description: If there is no filename, specifies whether or not to encode the CSV output into XML. This option should not be used when invoking the
outputcsvfrom the UI.
There is no limit to the number of results that can be saved to the CSV file.
Internal fields and the outputcsv command
The leading underscore is reserved for names of internal fields such as
_time. By default, the internal fields
_time are included in the search results in Splunk Web.
outputcsv command is used in the search, there are additional internal fields that are automatically added to the CSV file. The most common internal fields that are added are:
To exclude specific internal fields from the output, you must specify each field separately using the
fields command. Specify the
fields command before the
outputcsv command.. The negative symbol ( - ) specifies to remove the fields.
For example, to remove all internal fields, you specify:
... | fields - _* | outputcsv MyTestCsvFile
To exclude specific internal fields from the output, you must specify each field separately. For example:
... | fields - _raw _indextime _sourcetype _subsecond _serial | outputcsv MyTestCsvFile
outputcsv command merges values in a multivalued field into single space-delimited value.
The command saves the
*.csv file on the local search head in the
$SPLUNK_HOME/var/run/splunk/ directory. The
*.csv files are not replicated on the other search heads.
1. Output search results to a CSV file
Output the search results to the 'mysearch.csv' file. The .csv file extension is automatically added to the file name if you don't specify the extension in the search.
... | outputcsv mysearch
2. Exclude internal fields from the output CSV file
You can exclude unwanted internal fields from the output CSV file. In this example, the fields to exclude are
index=_internal sourcetype="splunkd" | head 5 | fields - _indextime _sourcetype _subsecond _serial | outputcsv MyTestCsvfile
