![]() | makeresults count=5 | eval city="Ontario" | makeresults count=5 | eval Country="Canada" The search with regex and != in the following example creates 5 events with Country="Canada" and 5 events with City="Ontario", and filters on events where Country does not equal "Canada". This example uses a negative lookbehind assertion at the beginning of the expression. If you use != in the context of the regex command, keep this behavior in mind and make sure you want to include null fields in your results.Įxample 1: Keep only search results whose "_raw" field contains IP addresses in the non-routable class A (10.0.0.0/8). For example, this search will not include events that do not define the field Location. You can use a search command with != to filter for events that don't contain a field matching the search string, and for which the field is defined. The search command behaves the opposite way. For example, this search will include events that do not define the field Location. ![]() You can use a regex command with != to filter for events that don't have a field value matching the regular expression, or for which the field is null. If you use regular expressions in conjunction with the regex command, note that != behaves differently for the regex command than for the search command. Use the rex command to either extract fields using regular expression named groups, or replace or substitute characters in a field using sed expressions. Use the regex command to remove results that match or do not match the specified regular expression. The difference between the regex and rex commands See SPL and regular expressions in the Search Manual.Īlthough != is valid within a regex command, NOT is not valid.įor general information about regular expressions, see About Splunk regular expressions in the Knowledge Manager Manual. When you use regular expressions in searches, you need to be aware of how characters such as pipe ( | ) and backslash ( \ ) are handled. The regex command is a distributable streaming command. To keep results that do not match, specify !=. You can specify that the regex command keeps results that match the expression by using =. Optional arguments Syntax: Description: Specify the field name from which to match the values against the regular expression. The regular expression must be a Perl Compatible Regular Expression supported by the PCRE library. Regex (= | != | ) Required arguments Syntax: "" Description: An unanchored regular expression. The only thing I can think of is that the token tablevariable isn't getting set but it should be due to the user click selection in the row.Removes results that match or do not match the specified regular expression. The problem is that the chart never appears, it simply says Search is waiting for data. ![]() If the value in the table is Cox Home Life - CHL, set the $s_mso$ token to "Cox" and then in the query search where s_mso="Cox" (there is some upper to lowercase conversion there, but let's ignore that for now as I know it works) Index=mso_statistics sourcetype=ic_connectivity_5min-too_small stat_name = "cell" |where mso=lower("$s_mso$") | eval stat_val=round(stat_val,2)| timechart first(stat_val) as "Cell Connectivity"| And the resulting chart chart depends="$tablevariable$">Įxpanded Cell Connectivity for - $tablevariable$ ![]()
