HP Insight Control for Linux 6.2 User Guide

• If the output reports that vars.ini have been resynchronized for a managed system,
verify that there is a self-signed certificate for the Apache service and that that service is
running. For troubleshooting information on the Apache service, see Section 25.3 (page 220).
25.14.7 Nagios gather_all_data script reports check_nrpe errors
These errors include socket timeouts and refused connections. The nrpe daemon is unable to
configure the server because the check_nagios_vars script is unable to write vars.ini to
the server.
Use the ping command, specifying the server by name; it returns its IP address. Compare that
IP address to the IP address that HP SIM reports for that server. They must match.
