Hi,
We recently updated our Linux kernel to Centos 7. In addition we also updated
ganglia from 3.5.0 to 3.7.2. Now when gathering metrics on a single system, the
syslog.txt file has numerous "/usr/sbin/gmond[4669]: Incorrect format for spoof
argument. exiting." error messages. I didn't see these error messages using
version 3.5.0. I programmatically change the override_hostname in the
gmond.conf file to the node's FQDN. I tried manually setting the override_ip
address, too, but that didn't help.
I've googled this error message and have seen some discussion here, but no
resolution: https://github.com/ganglia/monitor-core/issues/251.
Any idea why this changed in version 3.7.2?
It appears that some metric messages have the correct <ip_address>:<hostname>
format, and later the logs show the "Incorrect format" error messages:
# /usr/sbin/gmond -d 2
