SPLUNK REGEX HOW TO
The following sections give examples of how to use different operators in Splunk and Kusto. In Kusto, it can be used with the where operator. (2) In Splunk, the function is invoked by using the eval operator. In Kusto, it's used as part of extend or project. (1) In Splunk, the function is invoked by using the eval operator. | extend myTime = now() - totimespan("1d"). For example, search | eval n=relative_time(now(), becomes.

(1) In Kusto, Splunk's equivalent of relative_time(datetimeVal, offsetVal) is datetimeVal + totimespan(offsetVal). Kusto's returns a number between 0.0 and 1.0, or if a parameter is provided, between 0 and n-1. Splunk's function returns a number between zero to 2 31-1. In Splunk, searchmatch allows searching for the exact string. (1) Also note that Splunk uses one-based indices. (1) Also note that although replace() takes three parameters in both products, the parameters are different. The following table specifies functions in Kusto that are equivalent to Splunk functions. In Kusto, you can define a policy called ingestion_time that exposes a system column that can be referenced through the ingestion_time() function. In Splunk, each event gets a system timestamp of the time the event was indexed. Both have the ability to work dynamically with data types and roughly equivalent set of datatypes, including JSON support.Ĭoncepts essentially are the same between Kusto and Splunk. Kusto data types are more explicit because they're set on the columns. In Splunk, each event has its own set of fields. In Kusto, this setting is predefined as part of the table structure. Kusto logs have the concept of a table, which has columns. Splunk doesn't expose the concept of event metadata to the search language. Both implementations allow unions and joining across these partitions. This setting directly affects the performance of queries and the cost of the deployment.Īllows logical separation of the data. Splunk does not.Ĭontrols the period and caching level for the data. Kusto allows arbitrary cross-cluster queries.
