The startup warning indicator for the host. Only displayed when warnings exist. Click the host’s last ping for warning details. Ops Manager startup warnings can include the following:

  • Ops Manager suspects the host has a low ulimit setting of less than 1024. Ops Manager infers the host’s ulimit setting using the total number of available and current connections. See the UNIX ulimit Settings reference page.

  • Ops Manager flags a deactivated host.


    If you have deactivated hosts, review all deactivated hosts to ensure that they are still in use, and remove all hosts that are not active. Then click on the warning icon and select Reactive ALL hosts.
