Identify and Group Events into Transactions Introduction There are several ways to group events.

For example, over a 1 day search period take an average - or maximum or minimum or something - over a span=1m. Through this part of the Splunk tutorial, you will get to know how to group events in Splunk, the transaction command, unifying field names, finding incomplete transactions, calculating times with transactions, finding the latest events and more. A real-world example of how a transaction is used is a customer interacting with an eCommerce site.
Transactions usually include information such as the duration between events and the number of events (eventcount). When you have a large number of data points and you need a somewhat sensical graph, that is where doing timechart and aggregating over time ranges is essential. The transaction command allows Splunk users to locate events that match certain criteria. See How to specify relative time modifiers. This example uses a 'snap-to' time modifier to snap to the the start of the day. Example - on a 1600x1200 screen, even if the chart is full screen you only have enough room for about 1500 data points (assuming 1 pixel per data point). Basic example The following example determines the UNIX time value of the start of yesterday, based on the value of now ().
BUT if you have more than a few hundred data points, it starts to fall apart fast. This produces chartable data that is 24 hours wide with every data point in the sample represented. splunk is a data search engine for unstructured, structured data and used as real time monitoring tool, splunk stores data in its database(index).
I think there is some confusion by your use of the phrase "span=1d" because that is commonly a search argument to timechart - which will have to do some statistical aggregation because that is all it knows.Īn approach that you can use with limited data is something like this: index= transaction startswith="A started" endswith="A completed" If I understand what you are trying to say, you want a 24-hour chart with every transaction in that 24 hours and its respective duration.
