IP Node Monitor
The IP Node Monitor lets you monitor specific IP nodes on a regular basis. The IP node is associated with a host name or IP address, and is specified for
monitoring. The resolved IP address is then polled at regular intervals for the values you are interested in.
Usually this includes a ping with the following results:
■ If the ping is successful, the displayed device status indicates the device is reachable.
■ If the ping is unsuccessful, the displayed device status indicates that it cannot be reached.
Individual users can use filters to select which IP Nodes are displayed. The monitor displays the resources selected by the filter. The filter name is shown on the title line of the monitor panel. The IP Node Monitor uses the IPNODE filter by default.

Access the IP Node Monitor
You manage your IP nodes from the IP Node Monitor.
Follow these steps:
1. Enter /IPNODE at the prompt. The IP Node Monitor appears.

Note: The format of the IP Node Monitor can be tailored to your requirements.
Interpret the Status of IP Nodes
Use the following table to determine the status of monitored resources and nodes:
Monitoring Status
Actual State No Outstanding Alerts Maximum Alert Severity (1) Maximum Alert Severity (2) Maximum Alert Severity (3) Maximum Alert Severity (4)
Ok/Active ACTIVE OK - Green AlertSev1 - Red AlertSev2 - Yellow AlertSev3 - Pink AlertSev4 - Blue SNMPError/ Timeout DEGRADED MonError - Turquoise MonError - Turquoise MonError - Turquoise MonError - Turquoise MonError - Turquoise NoAttr/ Unknown UNKNOWN Unknown - White Unknown - White Unknown - White Unknown - White Unknown - White Error/Failed DEGRADED MonFailed - Red MonFailed -

Use IP Node Commands
To view the commands available on the IP Node Monitor, enter ? next to an IP node name.
A panel appears, listing the available commands in alphanumeric order by name in two groups. Commands that are specific to IP nodes appear first (displayed in turquoise), followed by other relevant commands.
To execute a command, enter S next to it.
Note: To list all the commands, enter ?? beside an IP node resource.
If you know the command, you can enter it next to the node directly.
Packet Tracing
You can trace packets between your system and the IP nodes by issuing SmartTrace line commands (see page 197) beside the IP node that you want to diagnose. For example, you can issue the PT command to start a trace. When a trace is active, a T appears in the Ovr column.
The PT command lets you specify optional criteria to limit the trace. It also lets you specify whether you want to create a separate trace for each new connection during the current tracing session.
You can list the started traces from the TCP/IP : Packet Tracing Menu.

Intensive Monitoring
When you are diagnosing a problem, you may want to change the sampling interval to less than five minutes (the normal minimum interval). To do this, you can apply intensive monitoring mode for a specified period.
Apply Intensive Monitoring Mode to an IP Node
To apply intensive monitoring mode to an IP node
1. Enter IMM next to a node name on the IP Node Monitor. The TCP/IP: Intensive Monitoring Mode panel appears. 2. Complete the following fields:
Name
Specifies the name of the attribute to be intensively monitored.
Sampling Interval
Specifies the intensive sample time required (minimum 15 seconds; maximum Duration of Sample, or one second less than the current rate for the selected attribute, whichever is smaller).
Intensive Mode Duration
Specifies the period for which intensive monitoring mode is applied (minimum one minute; maximum 30 minutes).
Press F6 (Confirm).
A confirmation message appears and X appears in the Ovr column of the selected IP node.
Reset Intensive Monitoring Mode for an IP Node
Use the IMR command to reset intensive monitoring mode for an IP node. This command sets the selected node’s sampling rate (for all attributes) back to the group attribute rate.
To reset intensive monitoring mode for an IP node
1. Enter IMR next to a node name on the IP Node Monitor. A confirmation message appears.
2. Press Enter.
Intensive monitoring mode is reset for the selected IP node and X is cleared from the Ovr column.
Performance History
Chapter 6: Managing IP Nodes 101
Performance History
Your region stores performance history data for IP nodes that are being monitored for up to the last 70 days. You can view this data in a variety of formats by issuing line commands against a resource on the IP Node Monitor.
More information:
Performance History (see page 275)
MIBinsight Browser
MIBinsight lets you display the SNMP MIBs for an IP node. You can access the MIBinsight browser from the IP Node Monitor by issuing the MIB line command.
