Dedup: Splunk Commands Tutorials & Reference Commands Category: Filtering Commands. There are a wide variety of search expressions that you can specify with the search command. Typical examples of a dedup produce a single event for each host or a pair. Runs a templated streaming subsearch for each field in aĮxample. The search command, along with the from command, is one of the most powerful commands in SPL2. `weather_data` | xyseries icon weather weather _time = starttime "| fields _time asaUser | timechartĬonverts results into a format suitable for graphing %M:%S" | map maxsearches=5000 search="|gentimes start=$et$Įnd=$lt$ increment=1h | eval asaUser="$asaUser$" | eval %S" | convert ctime(latest) as lt timeformat="%m/%d/%Y:%H: Min(_time) as earliest max(_time) as latest by asaUser |Ĭonvert ctime(earliest) as et timeformat="%m/%d/%Y:%H:%M: `find_asa_vpn_events` | `combine_user_names`| eventstats Useother=t limit=5 by _time | fields - percent" | timechart sum(count) by $starttime$ latest=$endtime$ | bucket _time span=1h | top |gentimes start=-1 end=0 increment=1h | map maxsearches=24 search="search earliest= The results are returned as a table, such as: It takes each of the results from the previous search and searches in the windows indexįor the user's logon event. `first_search` | map search="search index=windows latest=$et$ username=$user$ Sourcetype=syslog sudo | stats min(_time) as et max(_time) as lt by user host Although some eval expressions seem relatively simple, they often can be. The eval command is versatile and useful. Looping operator, performs a search over each search result The eval command enables you to devise arbitrary expressions that use automatically extracted fields to create a new field that takes the value that is the result of the expression's evaluation. Range in this case is the absolute value of (Actual Temperature - Relative Humidity) ![]() `get_weather_data` | contingency weather range usetotal=f `get_iis_data` | contingency ua_browser ua_browser_version usetotal=f Is used to study the association between the two variables (count) of one variable in rows and another in columns, and | eval subsearch = if(host=,”setting_1”,”setting_2”)īuilds a contingency table for two fieldsĪ contingency table is a table showing the distribution | eval sample_ = Value| stats avg(m_*) as “*” `nest_data`| autoregress temp_f | eval diff = temp_f - temp_f_p1 | timechart span=15mĪvg(diff) as "Average Difference" eval(avg(temp_f) - avg(temp_f_p1)) as "Eval Diff” Splunk conf2014 - Lesser Known Commands in Splunk Search Processing Language (SPL) In this example duplicates must have the same combination of values the source and host fields. Remove only consecutive duplicate events. Keep results that have the same combination of values in multiple fieldsįor search results that have the same combination of source AND host values, keep the first 2 that occur and remove all subsequent results. Remove duplicate search results with the same host value and sort the events by the _size field in descending order. Sort events after removing duplicate values | from main order by ASC _time | dedup source 4. Remove duplicate results with the same source value. For information about creating a sample standard deviation, see the stdev function. A population standard deviation is calculated from the entire population. A sample population deviation is different than a sample standard deviation. Sorting the events ensures that the oldest events are listed first. You can use this function with the stats, eventstats, streamstats, and timechart commands. Use the order by clause in the from command to sort the events by time in ascending order, the default order. Sort events in ascending order before removing duplicate values Keep the first 3 duplicate resultsįor search results that have the same source value, keep the first 3 that occur and remove all subsequent results. Remove duplicate search results with the same host value. ![]() Remove duplicate results based on one field To learn more about the dedup command, see How the dedup command works.ġ. The following are examples for using the SPL2 dedup command.
