Cloud Agent parameter validation started...
Cloud Agent pre-requisite checks will be performed in background as IGNORE_VALIDATIONS is set to true. Non-fatal failures in validations will be ignored.
Warning(s) received while performing Pre-Requisite checks. Please fix them to proceed further. The details are -

1: OMCAGNT-2000 - The Fully Qualified Domain Name (FQDN) of the host cannot be established. The host name of the machine could not be evaluated. Configure the host name of the machine to FQDN format. Add the fully qualified domain name in the /etc/hosts file (Unix) OR <Drive>:\Windows\System32\drivers\etc\hosts (Windows) and ensure that it maps to the correct name and IP address of the host.  The recommended format is:
 <ip> <fully_qualified_host_name> <short_host_name>
 You can run the following commands on Unix to verify this:
 $getent hosts `hostname`
 $host `hostname`
 For windows you can run the following command to verify this:
 C:\ hostname
 In the output, the fully qualified domain name must appear in the second field as specified in the /etc/hosts file
2: OMCAGNT-2101 - Ulimit value for max user processes [1024] is less than expected value of [4000]. We require an absolute minimum of 4000 or higher for a successful installation, but we recommend you to set the ulimit to 100000 for an uninterrupted service of the Agent.
