split host in ganglia

Hey there.
you should create 3 different clinet files and edit the server conf file.

in client file: /etc/gmond.conf

change the name of the cluster ( prod, staging, qa ) and the port (8691,8692,8693)
copy client conf file to each correspoing client,and run:
/sbin/service gmond restart

change:
cluster {
name = "prod"
owner = "yourname"
latlong = "unspecified"
url = "unspecified"
}

udp_send_channel {
mcast_join = 239.2.11.71
port = 8691
ttl = 1
}
udp_recv_channel {
mcast_join = 239.2.11.71
port = 8691
bind = 239.2.11.71
}
tcp_accept_channel {
port = 8691
}

in client file: /etc/ganglia/gmetad.conf

add the data_source for of the each cluster ( prod, staging, qa ) and the port (8691,8692,8693) with at least one clinet from that farm.

data_source "prod" 10 prod-client-hostname:8691
data_source "staging" 10 staging-client-hostname:8692
data_source "qa" 10 qa-client-hostname:8693

once you changed the server file run:
/sbin/service gmetad restart

now, refresh the web client....

enjoy

rrpc_inq_stats

rrpc_inq_stats(3ncs) rrpc_inq_stats(3ncs)

Name
rrpc_inq_stats - obtain statistics about a server

Syntax
#include <idl/c/rrpc.h>

void rrpc_$inq_stats(handle, max_stats, stats, l_stat, status)
handle_t handle;
unsigned long max_stats;
rrpc_$stat_vec_t stats;
unsigned long *l_stat;
status_$t *status;

Arguments
handle A remote procedure call (RPC) handle .

max_stats The maximum number of elements in the array of statistics.

stats An array of 32-bit integers representing statistics about the server. A set of rrpc_$sv constants defines indices for the ele-
ments in this array. The following list describes the statistic indexed by each rrpc_$sv constant:

rrpc_$sv_calls_in
The number of calls processed by the server.

rrpc_$sv_rcvd
The number of packets received by the server.

rrpc_$sv_sent
The number of packets sent by the server.

rrpc_$sv_calls_out
The number of calls made by the server.

rrpc_$sv_frag_resends
The number of fragments sent by the server that duplicated previous sends.

rrpc_$sv_dup_frags_rcvd
The number of duplicate fragments received by the server.

l_stat The index of the last element in the returned array.

status The completion status. If the completion status returned in is equal to status_$ok , then the routine that supplied it was suc-
cessful.

Description
The routine returns an array of integer statistics about a server.

Restrictions
On the client side, because of the way the calls are defined and implemented in the run-time library you must explicitly call into the
entry point vector table for the interface to send an request across the network. The following is an example of a call that works as
desired:
(*rrpc_$client_epv.rrpc_$inq_stats)(handle,
(unsigned long) max_stats, stats, &l_stat ,&status);

The server sidestub routine calls the entry oint on behalf of the client. The results of the call are then passed back to the client.
