I know few people in this forum are using Bristol's Transaction Vision production to monitor Transactions E-to-E timing in WMQ/WBIMB environment. I was wondering if anyone could answer these questions,
1. Can we setup alerts in TV where a person gets notified (page/email) if a performance relaed event occurs. By performance event I mean if the transaction response time is greater than threshold.
2. Would TV capture underlying infrastructure realted problems, for example, if the MQ channel goes down, how would it report this event? At this point Transaction is not flowing to next point, so I'd expect it to generate some type of alert.
3. If a MQ App is hanging (not reading messages from input queue), would TV identify such problems?
4. Does TV run in real-time mode?
I appreciate your help.

I'll give a quick Bristol answer...
1. Can we setup alerts in TV where a person gets notified (page/email) if a performance relaed event occurs. By performance event I mean if the transaction response time is greater than threshold.
Yes, this is done by setting a response threshold on the specific transaction class that you wish to alert on, then enabling an action on that threshold to generate the event. The event is generated via Log4J internal to our code, so routing the event to pager/email/SNMP/database/syslog/whatever is just a matter of configuring Log4J. We provide an appender for Tivoli so that you can route the alert there as well.
2. Would TV capture underlying infrastructure realted problems, for example, if the MQ channel goes down, how would it report this event? At this point Transaction is not flowing to next point, so I'd expect it to generate some type of alert.
TV will report this as a delayed transaction or lack of transactions flowing along a specific path. TV does not monitor the MQ channel directly; we leave that to partners like BMC, Tivoli, and others who are concerned with the details of the MQ infrastructure.
3. If a MQ App is hanging (not reading messages from input queue), would TV identify such problems?
Yes, by setting an activity threshold on an application component. For example, TV can be made to alert you if a specific application has no messaging activity for more than 5 seconds.
4. Does TV run in real-time mode?
Depends on your definition of "real-time". We analyze events in parallel with the applications that we are monitoring, so it is not a situation where trace data is batched up and processed sometime later. But, TransactionVision events are transmitted to the Analyzer component running usually on a different server, so there is some small delay between when an event happens and when it is processed. Usually this is less than a second, but depends on the environment.
If your definition of "real-time" is in-band of the production applications, then the answer is no because we don't want to introduce unnecessary delays in the production environment. If you define it as within a few seconds of when events are generated, then the answer is yes.
Thanks,

Ken,
Thank you very much for the answers.
