server as this is a temporary change.
If the realtime server does not work even after entering the "iptables --flush" command,
disable selinux by editing the config file located at /etc/selinux/config and setting the
SELINUX parameter to disabled (SELINUX=disabled). Restart the system after disabling selinux.
NOTE: Navigate to /etc/hosts file and verify the DNS resolving for a hostname, or enter
hostname or hostname -i to validate the hostname and the ip address of hostname.

This section discusses troubleshooting HP XP P9000 Performance Advisor management station and

Advisor, the host agent might not appear under the Host Information tab in HP XP P9000
Performance Advisor. The reasons for the errors and the steps to resolve the issues are described
as follows:
Cause
The configured settings for the antivirus firewall installed on the management station might be
blocking the communication between the management station and the host agent.
Resolution
Look for the following error in the PerformanceAdvisor.log file. On a Windows host, the
PerformanceAdvisor.log file is located in the <Installation_Drive>:\Program
Files\xppa\hostagent\log folder. If it is a custom Windows host agent installation, the file
is located in the <Installation_Drive>:\<Installation_Directory>\hostagent\
log folder. On a UNIX host, the file is located in the /opt/xppa/hostagent/log folder.
