HP Software Customer Connection page 3 December 7th-141th, 2003 Monitoring Clusters – Where to get the data? Where is the source data for the APMINFO.XML file? MSCS resource GROUP “SQLgroup1” MSCS resource GROUP “SQLgroup2” SQL server instance names for “SQLVS1” and “SQLVS2\SQLINSTANCE2” DB SPI will discover SQL instances… Cluster Admin Utility and SQL Enterprise Manager (both on the cluster nodes) are best sources of information.
