IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Private network address filtering
In environments where private network addresses are not duplicated, you can change this behavior so that the Tivoli Management Services Discovery Library Adapter (TMS DLA) populates these computer systems.
The TMS DLA does not populate computer systems with data from private network interfaces configured according to Internet Engineering Task Force (IETF) RFC 1918 and IETF RFC 4193. For details about RFCs, see the RCF Index (http://tools.ietf.org/rfc/index). This behavior prevents the incorrect merging of computer systems when multiple private networks use overlapping address ranges.
To enable discovery of computer systems with private network interfaces, edit the IP address filters in the XML template files that control the TMS DLA behavior.
Procedure
- Back up the template files before editing.
- The template files are stored in $ITM_HOME/arch/cq/tmsdla on the Tivoli Enterprise Portal Server.
- The template files are stored in %ITM_HOME%\CNPS\tmsdla on the Tivoli Enterprise Portal Server.
- A template for each monitoring agent provides discovery data.
- Check each of the template files to determine whether it has one or more <tmsdla:filter> sections. For example, the template file names for the operating system agents are:
- knt_tmsdla.xml for the Windows OS agent
- kux_tmsdla.xml for the UNIX OS agent
- klz_tmsdla.xml for the Linux OS agent
- Update the multiple <tmsdla:filter> sections in each of the template files to contain only the filters for loopback addresses (127.0.0.1 for IPv4 and ::1 for IPv6), as shown in the following example:
<tmsdla:filters> <tmsdla:filter name="IF_IP_ADDR" exclude="127\.0\.0\.1"/> <tmsdla:filter name="IF_IP_ADDR" exclude="::1"/> </tmsdla:filters>
What to do next
When an agent's application support is updated on the Tivoli Enterprise Portal Server, the agent's current DLA template file with your modifications is renamed to use the .bak extension and the latest version of the template file is installed. After the application support installation is complete, you must update the new version of the agent's DLA template file to contain the edits that you made to the IP address filtering in the *.bak version of the template file.
