Have any of you successfully configured ganglia on CentOS 8 (or RH or
any other equivalent)? If so, please share the method, because it is
not working right for me.
To set it up on CentOS 7 it was just installed from EPEL, gexec turned
on in /etc/ganglia/gmond.conf, and enable, start with systemctl.
There was no package I could find for CentOS 8 so I tried both
rpmbuild --rebuild ganglia-3.7.2-30.fc32.src.rpm
and
rpmbuild --rebuild ganglia-3.7.2-31.fc31.src.rpm
Both of those built apparently OK. Most recent install with:
dnf install ganglia-3.7.2-31.el8.x86_64.rpm
ganglia-gmond-3.7.2-31.el8.x86_64.rpm
ganglia-gmetad-3.7.2-31.el8.x86_64.rpm
#edit /etc/ganglia/gmond.conf to "gexec = yes"
systemctl install gmond.service
systemctl start gmond.service
There is just the one node ("poweredge.cluster') and gstat shows this:
CLUSTER INFORMATION
Name: unspecified
Hosts: 0
Gexec Hosts: 0
Dead Hosts: 0
Localtime: Mon Mar 30 12:21:27 2020
There are no hosts running gexec at this time. If gmond is run manually
with
gmond -d 20 -f
it shows that it is collecting data, and that it sees the host, and it
shows that the gstat request was received and serviced. This:
telnet 192.168.0.121 8649
elicits a well formed XML response, but one devoid of data. Here is the
end part of it:
