27.3 Using the Default MIB File with External SNMP Systems

When Access Manager is installed, NAM.mib file is placed in the opt/novell/devman/share/conf folder. On a Windows server this file is placed in the C:\Program Files\Novell\Tomcat\webapps\roma\WEB-INF\ folder.

This MIB file contains textual information of Identity Server and Access Gateway attributes. You can use these attributes to monitor the state of the system. The attributes are uniquely identified by an OID (Object Identifier) or namespace. Figure 27-2 shows the hierarchy of a MIB file when viewed with a MIB browser.

Each statistic entry in the MIB file has a corresponding description to help identify the attribute.

Every time a new Identity Server or Access Gateway is added or removed the SNMP data available in Administration Console is updated. If a device is not accessible for some reason, the MIB file (when viewed with a MIB Browser) displays the last reported statistics for all the attributes except for the Health Status of the devices. The Health Status of the devices are updated periodically.
