Pattern Matching to Return Node Names
The node mapping tool uses pattern matching to return a node name on
stdout. When the problem node has been highlighted in the Node Bank,
the node mapping tool uses pattern-matching to look up the specified
node name on the corresponding NNM system. In this way, it locates the
hostname or IP address patterns in a match table.
The pattern-matching procedure is carried out from the top of the file to
the bottom, until the first pattern matches. If a pattern matches, the
specified target node will be returned. If none of the patterns match, the
output will be empty.
Syntax for the Node Mapping Tool
You use the opcmapnode tool as a dynamic target node command in the
HPOM application, in backquotes, as follows:
‘opcmapnode ‘
For more information, see the man page opcmapnode(1m).
Configuring the Node Mapping Tool
When passed, opcmapnode reads the following file:
/etc/opt/OV/share/conf/OpC/mgmt_sv/opcmapnode.conf
This configuration file contains an HPOM pattern in every line, followed
by a node name, or by the variable $MGMT_SERVER, as follows:
^.site1.my.domain$ system1.my.domain
^.site2.my.domain$ system2.my.domain
^.$
$MGMT_SERVER
If opcmapnode is started in this configuration file, any nodes in domain
site 1 are mapped to system 1, any nodes in domain site 2 are mapped to
system 2, and all other nodes are mapped to the HP Operations
management server.
NOTE
If no node name is returned by opcmapnode, the only available NNM
system is locally installed. If the mapping file does not exist, or if it
contains no pattern lines, all NNM nodes will be mapped to the
management server.
