Hello, I have a strange problem with my fresh ganglia install.
I installed gmond/gmetad on one Server (server-A)
I installed gmond on another Server (server-B)
Gmond-Config on "server-A" is:
cluster {
name "server-A"
[...]
}
udp_send_channel {
host=<ip-of-server-A>
port = 8649
ttl = 1
}
udp_recv_channel {
port = 8649
bind = <ip-of-server-A>
}
tcp_accept_channel {
port = 8649
bind = <ip-of-server-A>
}
Gmond-Config on "server-B" is:
cluster {
name = "server-B"
[...]
}
udp_send_channel {
host=<ip-of-server-B>
port = 8649
ttl = 1
}
udp_recv_channel {
port = 8649
bind = <ip-of-server-B>
}
tcp_accept_channel {
port = 8649
bind = <ip-of-server-B>
}
Gmetad-Config on "server-A" is:
data_source "clusterA" <ip-of-server-A>:8649
data_source "clusterB" <ip-of-server-B>:8649
Now the sending seems to work, server-A and server-B get queried by the gmetad
and the rrd files are created according to the expected cluster configuration.
I verified this by telnetting to the gmond's on the two machines and to the
gmetad. Both Clusters are shown correctly in the gmetad-xml and all hosts of
the clusters (always just one host) are also shown correctly.
When i now open the Web-Interface, I get the server-B-Cluster preselected and
cannot change the cluster. In the hosts dropdown I can see the one host for the
server-B cluster correctly.
When I manually change the url I will get correct results if I use "c=server-A"
and "h=host.for.server-A", since the gmetad correctly created the RRDs. But the
bottom graph on the page is broken in this case and
shows "c=server-A&h=host.for.server-B" which of course will not work.
It somehow seems, that the web frontend cannot correctly read the information
from the gmetad in some way and cannot render it correctly although when i look
at the xml, it seems correct.
There are no Errors in either gmond or gmetad shown at debug level and i will
only get an error in the webserver logfile, that the rrd for the wrong host
cannot be found.
Can anyone help me with this strange problem?!
Best regards
Manuel R.
