Troubleshooting
The following tips may be useful if you experience issues with the
Performance Monitor Service.
Network Issues
Verify that multicast is enabled on all networks. If multicast is not
supported or available among the cluster nodes, take these steps on all
nodes in the cluster:
1. Add the following Windows registry entry to prevent the automatic
regeneration of the file <install_dir>\perfmon\conf\gmond_comm.conf.
Registry Key: HKEY_LOCAL_MACHINE\Software\PolyServe\MatrixServer
ValueName: MxperfIgnoreGmondCommRewrite : REG_DWORD
Value: 1
2. Edit the gmond_comm.conf file so that it specifies all cluster members
explicitly on all of the nodes. The following sample configuration is
for a two-node cluster with nodes 99.10.1.1 and 99.10.1.2. The file
content will be the same on all of the nodes.
udp_send_channel {
host = 99.10.1.1
port = 8649
}
udp_send_channel {
host = 99.10.1.2
port = 8649
}
udp_recv_channel {
port = 8649
family = inet4
}
The above steps must be performed on new nodes added to the cluster.
Processes Are Not Running
When the Performance Monitor Service (mxperfsrv) is started while the
system is under extremely heavy load, one or more processes may
terminate. The service will make several attempts to restart the failed
