  • 1.  Event coalescing

    Posted Sun May 09, 2021 01:25 PM

    Hi,

    We have a big number of reporting hosts using Wincollect, and therefore a lot of events are being coalesced.

    We don't want to disable the event coalescing as it will add a lot of eps, but there is a specific host which we don't want it's events being coalesced.

    Is there an option to exclude specific host from the event coalescing? or to add additional attribute to the test if the events can be coalesced ?

    Hi,

    You can turn on/off the Event coalescing feature on a per log source basis.

    If you want to turn off the Event coalescing for a particular host, go to the log source configuration (you can also use log source management app) of that host and turn off the event coalescing and save the log source configuration.

    Let me know if it helps.

    Thank you.

    Hi, thank you for the reply.

    I wanted to know if there is an option to turn the coalescing just for specific host, and not the entire log source.


    Will turning the coalescing off effect the EPS rate ?

    Hi,

    One note: Coalescing will not reduce eps usage. License limits are checked BEFORE coalescing. Coalescing will help with performance and disk space usage, however.
