Transactions within transactions

tyronetv — Mon, 19 Aug 2013 18:30:19 GMT

I have a set of two logs that share a common field (RID). One log contains the "user" actions while the other log contains the java, odbc, etc., actions (ibatis log).

What I need to do, is figure out if there is a delay between when a user makes a request and the actual connection to the database.

As you can see, the connection is VERY fast. Unfortunately, sometimes, it is not. When it is NOT we have a problem that is about ready to increase exponentially and cause some pain for our customers and, well, me.

What I want to do is put in place a 'real time' monitor that says the time between the line with <DAO CALL START> in a sourcetype of t2_app and the java.sql.Connection in the sourcetype of ibatis cant exceed X seconds or milliseconds. (And, also to be able to graph normal response times.)

I can do a <DAO START> to a <DAO COMPLETE> but that is too much. Just need to know from start to DB connect.

Suggestions?

Thanks!

How do you relate the db connection to a particular DAO START message? Or is it always sequential so you can count on that the first connection following DAO START is the connection that's related to it?

AFAICT from the logs, and because I am doing a transaction based upon the RID, the connect is just the next sequential step after the DAO START.

Perhaps something like

... | transaction RID startswith="DAO CALL START" endswith="java.sql.Connection" | search duration>1

Doesn't work. Been there done that. 😞

As you can see from my example, there are multiple connections to the DB under one RID.

I need each one encapsulated and that search didn't do it for me.

The startswith argument means transaction will begin a new transaction whenever it sees that string. What are your results when you use this?

transaction RID startswith="DAO CALL START" endswith=" Connection"

Yeah... I should of figured that out sooner.

Thanks for the assist though.
