Hello!

We are facing this alert about InformationStore (Exchange 2016) thats under 90% in 10 minutes.

The counter Database Cache Hit % is flapping basically all the time between 0 and 100%.

This server supports only one Database, has 16GB's of Memory and all the process together are consuming 90%.

The process Worker is consuming about 1GB.

Is this all right? Someone can tell me how can I fix or avoid this alert?

    Hi, @Victor Florêncio

    The alert indicates that Database Cache Percent Hit should be over 90%.

    Please refer to this document: Mailbox Server Counters
    It is about Exchange 2010 while also applies to Exchange 2016.

    I suppose that the problem may be related to memory problems.
    Can you find some related warning or error events in the event viewer>application log?

    In addition, it is recommended to use the Exchange 2016 Server Role Requirements Calculator to calculate the required RAM and other hardware requirements for your Exchange server.
