HP_iLO_NAGIOS_INTRO="The \"hpeilo_nagios_config\" configuration script will help you to create HPE iLO nagios plugin configuration file which is later can used for active/passive HPE iLO host servers discovery and configure the nagios configuration file on monitoring host.\n\nFollowing are the parameters,user has to configur to get \"nagios-plugins-hpeilo\" to work efficiently.\n\n"
HP_iLO_NAGIOS_INTRO_1="\e[1mActive discovery: \e[0mActive discovery scans all reachable HPE iLO servers in the network of the monitoring server. This approach can discover all HPE iLO servers in a given network ip range or network subnet.\nNote: Active discovery is a time-consuming process and it depends on total number of hosts in a network subnet or IP range.\n\nYou have to enable to do active discovery in HPE iLO nagios plugin configuration file to scan all HPE iLO servers one time.\n\n"
HP_iLO_NAGIOS_INTRO_2="\e[1mPassive discovery: \e[0mPassive discovery discovers HPE iLO servers once receiving the cold start traps generated by those servers.\nThe traps are generated when those servers get booted successfully, so this approach cannot discover the up and running servers.\nAlso it is required to add \"traphandle\" command and community string in \"snmptrapd.conf\" file as mentioned in the below example.\n\t\"authCommunity log,execute,net <community string>\"\n\t\"traphandle 1.3.6.1.6.3.1.1.5.1 ${Nagios_iLO_Plugins_Path}/nagios_hpeilo_cfg_generator -m 2 \n\t${Nagios_iLO_Plugins_Path}/hpeilo_nagios_config.cfg\"\n\t\"traphandle 1.3.6.1.4.1.232.0.* ${Nagios_iLO_Plugins_Path}/nagios_hpeilo_traps\".\nThe \"snmptrapd\" service will be restarted once its configured.\n\nYou have to enable Passive discovery in  HPE iLO nagios plugin configuration file to add the HPE iLO server on receiving cold trap.\n"

HP_iLO_NAGIOS_INTRO_3="\e[1mHPE iLO server Host Group: \e[0mA HPE iLO server Host Group  is used to group one or more HPE iLO servers together under one group.\nIt consists of \"Group Name\",\"IP address range or Network subnet or IP address\" and \"Community string\".\nThese data are used to configure nagios \"Host Group\" Directives for simplifying configuration with display purposes.\nAn example of HPE iLO Host Group is as below\n\t\"HOSTGROUP:HPE_iLO_Group_1,192.1.10.20-192.1.10.200,public,public\"\n\nYou have to add at least one Host Group to discover the HPE iLO servers using any of the above mentioned discovery method.\nNote: Default generic host group will be created and the discovered HPE iLO servers will be added to this group if the discovered HPE iLO server IP does not belongs to any of the configured host groups.\n\n"

HP_iLO_NAGIOS_NET_INTERFACE_INTRO="Active discovery requires network interface to scan all HPE iLO host's over the network.\nYou can find the network interface by running the command \"ifconfig -a\".\nMake sure network interface is up and ip is mapped to the HPE iLO host group ip range specified while configuring HPE iLO host group.\n"

HP_iLO_NAGIOS_HOSTS_INTRO="HPE iLO host group configuration.\nHPE iLO host groups can be created with a range of IP address or a IP address.\nYou can also create host group based on SNMP read only community string.\nDefault generic host group will be created if host group is not configured or if HPE iLO host which are discoved and not in the configured host group\nIP range will be added with default \"public\" SNMP read-only community to the default host group name.\n"
