Package: ganglia-monitor Version: 3.6.0-2 gmond nodes send metrics to each other of multicast or unicast using UDP packets
When a gmond receives a packet, it tries to resolve the source IP and store that in the data structure for generating the XML If resolution fails, it simply stores the source IP in the field for the hostname. As a consequence, the gmetad becomes polluted with RRD directories named by IP address. As a bare minimum, it should probably log a warning to syslog in this situation. Even better, it should not accept these packets at all. For people who want backwards compatibility, a configuration option should be created that allows the administrator to choose whether or not gmond stores metrics from unresolved sources. For new installs, the default option should disable the storage of these sources. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
