The SMTP availability of the Receive connector smtp inbound was low (38 percent) in the last 15 minutes.

    Question

  • We are using splunk to monitor exchange 2013. We keep getting these alerts "The SMTP availability of the Receive connector smtp inbound was low (38 percent) in the last 15 minutes."

    I was wondering do these monitoring thresholds need to be modified within exchange? I don't want to turn the monitor off. I just need to tweak it so that it alerts when there is a real issue. And not a false positive.

  • Hi,

    Do you have additional information on what the command will do? What will change with the smtp threshold alert? We have have 50GB plus free space on the drives. The servers do not hold the mailbox roles.
