There is also OpenNMS: http://www.opennms.org. Probably overkill for a single host, but good if you intend to scale up and since a yum repository is maintained, installing isn't bad. It normally uses snmp and remote probes of network protocols instead of a dedicated local agent, but does have the ability to use some NRPE stuff from nagios if you want. Don't think there is a usable 'read only' login for outsiders but it does have an embedded jasper reports server for publishing fancy reports that can be emailed as pdfs. -- Les Mikesell lesmikes...@gmail.com _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
