Group together events that do not have a common field values

[nitishnair123]

I have a log file from which I am pasting a particular group of events as below:

These events may occur multiple times with the below pattern observed in sequence in which these events occur:

This event will always come at the beginning of the group ->
EAITransport EAITransportDebug 4 xxxxxxxxxxxxxxxx:0 xxxx-xx-xx xx:xx:xx Invoking JMS Java method Receive
This event will always mark the end of the group ->
ObjMgrBusServiceLog InvokeMethod 4 xxxxxxxxxxxxxxxx:0 xxxx-xx-xx xx:xx:xx Business Service 'EAI JMS Transport' invoke method 'ReceiveDispatch' Execute Time: xx.xxx seconds.

The aim is to be able to group all these events (that lie between and including the 2 boundary events) together.
I have tried using 'transaction', but from what I understand, that would need some unique field-value in each of these events that are to be grouped together. In this case, there doesn't seem to be any. Wondering if there is any way to achieve this.

[asimagu]

have you tried creating a mock-up field before building your transactions?

[nitishnair123]

Do you mean creating a new field and have that in all events that should comprise a transaction with a same value? I would have tried doing that, but the challenge here seems to be what value would I populate the mock field with? In the case above, I would then need to have dummy values that change for every group of common events that would define a transaction. The boundary events that define the start and end of the transaction would always be the same (of course apart from the timestamp field). Also to be noted that there can any number of events between the 2 boundary events.

[asimagu]

hummm, if the timestamp is the same, maybe you could use _time as that field, or a mockup field that may contain that _time value..... I cannot be sure, as I never faced that situation. It may worth trying?

[nitishnair123]

Thanks asimagu...but the timestamp will vary as and when these events get logged in the log file in sequence.
