  • 1.  monitor element

    Posted 03/31/20 03:12 AM
    installed dmc on linux and monitoring db2 luw databases
    being on screen : monitor - statement - package cache


    there is info like estimated runtime, but there is no indication how this is expressed : min-sec?
    there is no additional info from which monitor element this is originated and what this means
    this is very difficult to analyze and you need to go to command line interface to collect info and see what is happening
    the info/help on dmc screens is VERY limited and just giving info without any detail/help and can not be used to analyze if there is a potential problem

    Hello Guy,

    This is Ke from DMC development team. We appreciate your comments to make DMC better. I'm trying to answer your questions one by one.
    • Estimated runtime is in the format of hours:minutes:seconds.milliseconds. I'll suggest the design team to add more description for this column.
    • Package cache page is originated from table function mon_get_pkg_cache_stmt. It aims to display the executed SQLs on the monitored database. When you move the mouse on each row in the grid,  you will see an icon with three dots appears. It has several actions for this row. You can view more details via view detail button.
    • Could you explain more about the commands you need to run manually? Anything else you need to know to analyze if there is a problem? If we know what information you need, we could consider to add more actions to make it more helpful.

    Thanks,
    Ke

    thanks for the update
    but looking at knowledge center of Db2 : you see this element is not in use yet : so why displaying this ?
    ESTIMATED_RUNTIME BIGINT Reserved for future use.

    Hi Guy,

    This column will be hided as default. But as you know, it will be used for Db2 new versions. So we will keep this column.

    to answer part 2 :
    when displaying the details : it would be nice to have - to highlight some values/ratios that should get a focus
    eg. ratio between rows read/rows returned = high
    cpu time - physical read instead of logical read
    I know this is maybe an utopia - but that would enhance the product - you immediately know where is a potential bottleneck
    maybe for verions 4 ?

    Thank you for your suggestion. We will bring this request to group discussion. I think the hard part is how do we define 'high'.
    Please be aware that a new function is added by group decision.  We can not promise the request can be fulfilled and when it can be delivered.

    Thanks,
    Ke

    when displaying details about statements you could add next to a field something like in visual explain, three dots and when you place your cursor over it you see the details about it

    Guy, do you mean to use a hover window to display the detail information? The problem is that the detail has a lot information to display. In that case, a hover window may be busy.
