Using LinkView

LinkView is accessed from the SysPoint screen by clicking on a Stack IP Address hyperlink for the desired stack and then clicking Show LinkView from the drop-down menu. You can also access LinkView by clicking on the Monitor tab and then clicking the LinkView hyperlink under Critical Resource Monitors. LinkView is only accessible to Master or Operations Manager users.

The LinkView screen shows link and device information for each channel-attached processor associated with the selected TCP/IP address space. LinkView provides a synopsis of the Total physical links available, the Links Unavailable, and the Devices Unavailable. Detail information is provided by Channel Processor ID in the chart below. Click a Link Name hyperlink to open the Thru24 IP Summary or Detail report to view near-time IP throughput information for channel-attached devices. The Thru24 IP Summary report provides a comprehensive overview and the Detail report provides detail by interval (Current, Last, or Since Midnight). Context-sensitive commands can be executed (with full command user authorization) by clicking the buttons at the bottom of the screen to access command menus for: Gateways, OMPRoute OSPF Routing, OMPRoute RIP Routing, VIPA, or the VTAM Table.

 

Figure 24. LinkView

The fields on LinkView for channel device monitoring are:

Flag

Blank

No flag

I

Primary interface

P

IP address was created as a result of this TCP/IP being identified as a target stack for this address from a Sysplex distributing stack.

CHPID

Channel Processor ID.

 

IP Address

IP address of the link.

 

Link Name

Uniquely assigned link name. Hyperlink to the Thru24 IP Summary or Detail report, which provides near-time IP throughput information for the selected link.

Link Type

Category of network interface link associated with a device. For example, Ethernet.

Link Status

Link status is either Not active or Ready.

 

Device Name

Name assigned to this device

Device Type

Category of device (e.g. CLAW)

 

Device Status

Valid states for the device’s status may be:

·         Starting

·         Sent SETUP Request

·         Enabling

·         Connecting

·         Connecting2

·         Negotiating

·         Ready

·         Deactivating

·         Not active

 

Queue Size

Number of outbound packets for this link which are queued and waiting for ARP resolution.

 

MTU

Link Maximum Transmission Unit. Example: 576.

 

Thru-put In Bytes/Sec

Data transfer rate in (Bytes/Second).

 

Thru-put Out Bytes/Sec

Data transfer rate out (Bytes/Second).

 

Bytes In

Number of bytes received in the current time period. This is a delta value. The interval is defined in the DEVLINKMON statement. The default is 600 seconds.

 

Bytes In % of Total

Bytes In % of Total=Bytes In for One Link /(Total Bytes In for All Links). Percentage based upon a comparison between the Bytes In for one Link and the total Bytes In for all Links.

This is a delta value. The interval is defined in the DEVLINKMON statement. The default is 600 seconds.

 

Bytes Out

Bytes transferred for this channel device.

 

Bytes Out % of Total

Bytes Out % of Total=Bytes Out for One Link /(Total Bytes Out for All Links). Percentage based upon a comparison between the Bytes Out for one Link and the total Bytes Out for all Links.

This is a delta value. The interval is defined in the DEVLINKMON statement. The default is 600 seconds.
 

 

Note:

Bytes in and Bytes Out are the delta values between consecutive samples. All other data members are the current values obtained from the latest sampling event.
