One monitored Linux shows all, rest shows minimum

[hank.wojteczko]

Installed monitoring agent using Installing_The_XI_Linux_Agent.pdf instructions:
Installing The Agent
Download the Linux NRPE agent to the /tmp directory on the Linux server you wish to monitor.
cd /tmp
wget https://assets.nagios.com/downloads/nag ... ent.tar.gz
Unpack the installation archive you just downloaded:
tar xzf linux-nrpe-agent.tar.gz
Enter the newly created agent subdirectory:
cd linux-nrpe-agent
Run the wrapper script as root (if using Ubuntu you'll need to either run sudo -i to run as root or run the
command with sudo in front):
./fullinstall

Is there a config file on the agent that need changing? If so, where is it?

Can you send a screenshot of what you are getting for this host that isn't working?

Is the nrpe service running on the remote host?
Could there be a firewall blocking access to port 5666 on the remote server?
