![]() Note: The information for this diagram was provided by Nick Mealy. You can also read more about the stats commands in the "Calculate Statistics" chapter of this manual. You can read more about when to use stats and transaction in the topic "About transactions" later in this chapter. In most cases, you can accomplish more with the stats command or the transaction command and these are recommended over using the join and append commands. If you're not sure where to start, the following flow chart can help you decide whether to use a lookup, define a transaction, or try another search command to define your event grouping. Different events from different sources from the same host. Transactions can include: Different events from the same source and the same host. A transaction type is a transaction that has been configured in nf and saved as a field. Sometimes, there is no single command that you can use. A transaction is a group of conceptually-related events that spans time. Depending on your search criteria and how you want to define your groupings, you may be able to use a search command, such as append, associate, contingency, join, or stats. You can also use field lookups and other features of the search language. To try this example on your ownSplunk instance, you must download the. Use transactions to identify and group related events Transactions with the same field valuesYou have events that include an alertlevel.Use time to identify relations between events.This chapter discusses three methods for correlating or grouping events: Use SQL-like inner and outer joins to link two completely different data sets together based on one or more common fields. ![]() Correlate your data to external sources with lookups.Create conditional searches, where you see the results of a search only if the sub-search meets certain thresholds. Use a sub-search to take the results of one search and use them in another.Identify the amount of time it took to complete the transaction and the number of events within a single transaction. Track a series of related events, which may come from separate IT systems and data sources, together as a single transaction.Use this correlation in any security or operations investigation, where you might need to see all or any subset of events that take place over a given time period or location. Identify relationships based on the time proximity or geographic location of the events.Basically, whenever I request with the circuit id from UI it will create a new transaction id for that particular hit which means logs will have multiple requestids for the same circuit id for 1 day. Splunk software supports event correlations using time and geographic location, transactions, sub-searches, field lookups, and joins. Hi Team, My scenario is I have multiple request and response xmls which are basically my events in index for one circuit id. Event correlation is finding relationships between seemingly unrelated events in data from multiple sources to answer questions like, "how far apart in time did a specific set of events occur?" or "what's the total amount of time it took for a transaction to complete?"
