Load Monitor

Running Load Monitor

5967–9446 249

The view window shows data from the selected data source. Depending

on how you launched Load Monitor, you may be able to select a different

data source within the application, as discussed on page 256.

When communicating with an ERM, you can display views based on data

from any of the ERM’s associated data sources. However, when you

launch against a particular ERM data source, you can attach only to that

data source; other data sources associated with the same ERM will not

be visible.

If you select more than one data source, a separate copy of Load Monitor

is started for each one. If you select more than one ERM data source, a

separate copy of Load Monitor is started for each one even if the multiple

selected data sources are associated with the same ERM.

Note: If your network has changed, you may encounter this message

when you launch the Load Monitor for an ERM or a probe: “Agent

xx.xx.xx.xx not found in agentdb.mgr.” (Where xx.xx.xx.xx is the IP ad-

dress for the agent.) The Agent Manager must be updated to show the

changes. To see the current state of the ERMs in your conﬁguration,

launch the ERM Monitor by selecting Misc➤ ERM Monitor. You will re-

ceive a list of the actual associations. To update the tree, highlight the

ERM you wish to update, then select Edit➤ Contact Selected. This will

update association information in the tree for the new probes and re-

move any that no longer exist in the conﬁguration. New probes will be

listed as unknown. With the ERM still highlighted in the tree, select

Edit➤ Contact Unknown. This will cause the Agent Manager to con-

tact the ERM and update the list of probes. The Agent Manager will now

know the probe types and list them accurately in the tree.

You can also start Load Monitor with the loadmon -agent <IP ad-

dress> -interface <ifIndex-#> -use_ext command.

OpenView NNM

The OpenView NNM Load Monitor menu items are context sensitive. To

launch against an ERM, ensure that the host’s symbol indicates the

agent type. To change the symbol type, use mouse button 3 on the host

symbol, select Change Symbol Type…, select the symbol class for

Network Device, then choose ERM.
