Nagios configuration can only be generated if the nodes have static IP addresses.  Static IPs are used so we can monitor the specific nodes in the cluster. Dynamic IPs will move between nodes as needed and is not a reliable way to monitor specific nodes in the cluster.  A good example of how this could cause an issue is the basic ping that nagios does to check if the host is online. If dynamic IPs are being used with Nagios to monitor the nodes in the cluster, pinging the nodes would not be a reliable way to determine if a node is up/down since the IP would move to another node.
When trying to generate a global or a cluster Nagios Configuration, i always get the error message "Error generating config file: No static IP addresses available for node 1 No configuration file generated." We are currently using 15 nodes with OneFS 7.1.1 with dynamic address allocation ... can the nagios config only be generated while using static addresses? Which benefits do we have of static ips?
Cannot generate Nagios Configuration
