LAN Network Manager Daemons and Executables

The LAN Network Manager component invokes several daemons and executables (shell scripts and compiled programs). These daemons and executables are stored in the /usr/CML/bin directory. The following list briefly describes the daemons and executables. For more detailed information, refer to the online man page for the specific daemon or executable. To display a man page, type:

man topic

Where topic is the name of the daemon or executable for which you want more information.

Process Name

Description

nvot_server

Maintains Nways Manager-LAN topology database.

cmld

Manages lnmtopod and the monitoring applications that are part of LAN Network Manager and provides a communication channel for the LAN Network Manager command line interface.

cml_agent_found

Initiates the discovery of a specified agent.

cml_agent_remove

Stops monitoring an agent.

lnmexport

Converts current week performance data collected by the OS/2 agent to a spreadsheet-readable delimited format.

lnmfddimgr

Manages the LAN Network Manager FDDI application.

lnmfddimon

FDDI SNMP Proxy Agent monitor process.

lnmlnmeint

Manages the sending of run command requests to the LNM OS/2 Agents from LAN Network Manager and the receiving of the run command responses from the LNM OS/2 Agents by LAN Network Manager.

lnmlnmemgr

Manages the LAN Network Manager LLC token-ring application.

lnmlnmemon

OS/2 agent monitor process.

cmlstart

Starts a specific daemon.

cmlstop

Stops a specific daemon.

cmlsm

Contains the Symbols Manager files (see the online book User Interface for more information).

cmlstatus

Displays the status of the LAN Network Manager daemon processes.

lnmtopod

Provide monitoring and management support by integrating multiprotocol networks into a single LAN interconnect topology hierarchy.

lnmbrmon

SNMP Bridge monitor process.

lnmbrmgr

Manages the LAN Network Manager SNMP bridge application.

lnmtrmon

SNMP token-ring monitor process.

lnmtrmgr

Manages the LAN Network Manager SNMP token-ring application.

lnmhubint

Communicates with the Hub Manager iubd daemon to manage the LAN Network Manager Hub Manager integration function.

LAN Network Manager Performance Data Files

The files used for segment and bridge performance data are stored in the /usr/CML/reports/lnmlnmemon/dir_name directory, where dir_name is the IP address of the OS/2 agent that manages the segment that is collecting the data.

There are two types of files used to store segment and bridge performance data, each with the following naming structure:

yyyxxx.history.nn

Where yyy is either seg or brg, xxx is either the number of the segment or the symbolic name of the bridge, and nn is either 01 or 02. The extension 01 is used to store data that is currently being collected. The extension 02 is used to store data from the data collection period that has most recently completed.

For example, the file seg005.history.01 stores performance data for segment 005 from a collection period that is currently active. When this collection period ends, the file is renamed seg005.history.02, replacing the file currently using that name, if necessary.

If you display a segment or bridge performance graph using the Graph History push button on the Segment Performance or the Bridge Performance Graphing window, the data from the 01 file is displayed, unless the 01 file does not exist, in which case the historical data in the 02 file is displayed. If data has never been collected for a segment or bridge and neither file exists, the LAN Network Manager program cannot display a performance graph.
