Hi All,

also i have another question when i defined the sequence transaction, how correlate between steps ?

Hi all,

Thanks for the help, I think I know why I couldn't see my sequence transactions earlier.

It seems to be because I configure the sequence transactions using those operation I see in waterfall chart in ADS.

After I change it to be constructed from "higher-level" operation (which I obtained from user activity table, to see all the operation/URL he has triggered), then the data/statistic for this sequence transaction comes in.

I hope this the cause of it.

That would make sense, as the ADS waterfall charts will list components of an operation as well as the operation itself, but the sequence transaction definition must be comprised only of operations.

I think there are some major differences between transactions and sequence transactions regarding metric calculation and definition.

Definition: Sequence Transactions are defined on one "service" or tier, they consist on several consequent operations. It is more like a process that is mapped to a sequence transaction with a start point (a defined operation) and a defined end point (a operation as well). On the other hand are the transactions (defined in business units), they can include different tiers like webfrontend, middleware and database which are needed to get a function in application running (like the Login "function"). Therefore they can include different tiers, services and protocols.

Metrics: For transactions the number of transactions is identical to the number of operations for all operations that are part of the transactions and the response time for example is the average of the response times for all operations that are part of the transaction. On the other hand are the sequence transactions - the number of transactions is calculated as number of sucessfull process matches (sequences starting from start point operation and ends on end point operation) regardless how many operations are in between. The transaction time is calculated like the time between start and end operation.

These are only a few examples.

Hi all,

I am well aware that what the 'tier, application and transaction' are, as they are very useful and already being used in many of the CAS reporting.

And then, I am just starting to explore sequence transactions, which I perfectly understand what it saids in the documentation. But when it comes to reporting in the CAS dashboard, I can't even find one, how can I view any statistic/charts/tables about Sequence Transactions in CAS? Using DMI? or there is some other things that I am missing?

Regards,

Hi Wai,

Check the applications Technologies Report (under applications overview report on the second tab). It should report the performance of sequence transactions with some drilldowns assuming there was activity in the given timeframe. Hope this helps.

Hi,

Sequence Transactions can be found in the "Synthetic and Sequence Transaction Data" and "Application, transaction and tier data" Data views, on the other hand transactions from business units can be found unter "software service, operation and site data" as well as "Application, transaction and tier data" data views.

For the "Application, transaction and tier data" data view there is a dimension called "Tier" which distinguish between both types.

Best regards,

Friederike

Hello Abdel Mohsen,

I took the below screenshots from one of the DCRUM presentation to understand the question accordingly.

Please let me know, if you were asking for the same.

Regards,

Babar

Thanks Babar,

Actually i was read the documenation, it was only mention how define the transaction without any information about use cases.

moreover i need to know how correlate between steps when i defined sequence transaction .

, for example let say i have one transaction contain 3 steps (start,confirm and execute), how the dcrum engin correlate the steps for same transaction .

Hello Abdel Mohsen,

The main difference between the transactions and sequence transaction is below:

  • Sequence Transactions should not have any user think time in the steps.
  • The steps listed must happen exactly in the order defined.
  • Priorities can be used for matching.
  • The most detailed sequences must have a higher priority.

You can read the below links for more clarification.
