Re: ITM

Ah, another compelling reason why IBM has been struggling to get customers
off of DM 3.7 Classic product ....it is much more user friendly.
ITM is a pain the donkey's behind really.   For 2 years,  IBM has not been
able to correct ITM's many major shortcomings.  I know that a new release is
due this fall to try and combine DM Classic & Candle agents before moving
into ITM in 2006 sometime....but ITM is just plain no good in practice.  It
is great conceptually in that it correlates etc.     Take a look at what
NetCool is doing....no agent code needed on monitored servers...it learns
the servers normal behaviour,  reacts only when a particular server is out
of norm....very very nice indeed.  ITM is unfortunately built on the
presumption that all servers are relatively equal.......maybe true in IBM
lab.......but not in customer's world.

We only use out of box resouce models and absolutely refuse to use the
Resource model builder to add BASIC capabilities that DM provided.   The RM
builder is OK for adding monitoring for components/elements not covered by
ITM out of box, but not features such as multiple thresholds,  distributing
scripts/code for task execution.

Many ITM Resource models are not even pertinent to the OS they
monitor....one key one is TMW_LogicalDisk.....it calls for a pecentage in
the setting of thresholds (no coding of bytes/MB etc) and cannot ignore any
LogicalDisks...... while the DMX Unix RM allows for coding of MB.

This makes the TMW RM completely irrelevant due to varying disk sizes.
Just imagine hat happens when a Windows admin gets paged due to a TEC event
indicating server "X" has only 1%  disk space on Logical disk D .....when
disk D is 200GB...thats 2GB still free!!   The OS admin will tell you to
jump off a bridge.
ITM must be redesigned.  Our shop is testing MS MOM for all windows
monitoring.  Thus far it is going well and we will likely end up pulling the
plug on 3/4 of our ITM presence before too long.  IBM really messed up with
ITM.

Hi list,

is it possible to distribute an custom configurationfile together with a
Ressource Model Profile , like the Distribution Action in DM3.7.
