Section 3 = Using ManageWise to Create a Database of System Components

8

Explain the ManageWise components and files that are responsible for the network discovery process.

 

 

·         NetExplorer:   runs on NetExplorer server

·         NetExplorer Manager:   runs on Managewise Console Station

·         NetExplorer writes discovered information to:

SYS:\NMDISK\NETXPLOR.DAT and NXPDISK.DAT

·         NetExplorer Server send records to SYS:\NMDISK\NETXPLOR.DAT to NetExplorer Manager on a MW Console station

·         NetExplorer Manager stores records in MW database on MW Console

 

·         NETXPLOR.NCF:

search add sys:\nmdisk
load sys:\nmdisk\netxplor
load sys:\nmdisk\nxpcon
load sys:\nmdisk\nxpip – collects TCP/IP-related data
load sys:\nmdisk\nxpipx – collects IPX/SPX-related data

load sys:\nmdisk\nxplanz – collects info from LANalyzer Agents

·        Discovery process:

o       IP discovery (using local router table info discover other routers and so on)

o        IPX discovery (NetExplorer server IPX address, LAN type of network boards, SAP. Then the same for each device listed in directory or bindery) Working directory sys:\nmdisk\nxpwork

o        Protocol-independent discovery (NXPLANZ identifies NW LANalyzer Agents, LANalyzer Agent on segment discover devices by MAC address in packets, NXPLANZ retrieves MAC address data by SNMP)

o        during initial discovery cycle, these modules run sequentially. Later they run concurrently (only new or changed data are send to NETXPLOR.NLM).

o       initial discovery can take from a couple of hours to several days.

9

Explain the function of the LANalyzer Console.

 

  1. LOAD LANZCON (F3 - toggle monitoring)
    2. Customize the operation of LANalyzer Agent.
    3. View statistical data including network adapter and LANalyzer Agent items.

 

 

 

 

 

 

 

10

Explain the function of the NetExplorer Console.

 

  • NXPCON configures and monitors NetExplorer on a NetExplorer Server
  • Used to schedule when discovery process cycles should be run
  • Status options:
         - NetExplorer Up Time – show time elapsed since NetExplorer started running
         -The number of Consoles Attached – can have up to 8 consoles attached

                       simultaneously to one NetExplorer Server

                 - NetExplorer System Status – shows overall status with 2 values:

o        Initial cycle in progress: at least 1 discovery module (NXPIP, NXPIPX, or NXPLANZ) has not yet completed its first cycle

o        Initial cycle completed: all modulaes have completed at least 1 pass

     - Module status – shows status of each module (NXPIP, NXPIPX, and NXPLANZ)

            and the number of cycles each module has completed. Status values:

o        Not Loaded

o        Waiting to Start

o        Running

o        Suspended

o        Completed

o        Unknown

  • NXPCON is automatically loaded when NetExploer (NETXPLOR) is loaded. NXPCON and NETXPLOR are typically loaded every time the server starts or reboots. However, you can also load NETXPLOR and NXPCON by typing LOAD NETXPLOR at the system console prompt.
  • To exclude a user from the discovery process, exclude the user's name using IPX discovery option.
  • For each NetExplorer Server, up to 10 MW Console stations can be attached.
  • NetExplorer and NetExplorer Manager can be scheduled but the two do not need to be synchronized.

 


 

 

Section 4 = Evaluating the Database

11

Prepare a detailed internetwork map through the use of the default Internetwork and Segment Maps.

 

Network documentation should include:

  • Maps that detail physical and logical layout of each network segment and their relationship to each other
  • Lists of addresses of all network devices and their locations:


MW provides three type of maps –

  • Internetwork Maps graphically depict the internetwork segments and routers, and the relationships among them.
  • Segment Maps detail each network segment, with icons representing the discovered devices
  • Custom maps show geographical or floor plan views.

 

MW automatically creates Internetwork and Segment maps based on info it gathers from NXPIPX (and NXPIP and NXPLANZ if running)

 

Internetwork map (File|Open|Internetwork map
     - can be in Tree (default) or Connected Graph formats. It shows the routers,  segments and logical connections between them.
     - In TREE view lines connecting routers and segments are called connection

       references
     - Larger networks are best viewed as TREE.

Segment map (File|Open|Segment map)
      - shows WS (IBM and Apple), servers, printers, routers, mainframes etc. from   

         that segment.
      - allows access to MW database for each component.
      - segment map is a launching point to remotely monitor and manage stations

12

List all the discovered IP and IPX network addressess using ManageWise View All Tables.

 

1. View|All|IP Networks
          - lists network numbers, subnet masks, media type
          - This list is not dynamic. It remembers all IP addresses that have been used on this

             network
2. View|All|IPX Networks
          - lists network numbers, media type, NW system names
          - if you have duplicate IPX addresses, they can be seen
          - similar to DISPLAY NETWORKS on NS server

13

List all the discovered Media Access Control (MAC) addresses using Desktop Manager.

 

  1. Select inventory server on segment map
  2. Tools|Desktop Manager
  3. View|Columns
  4. Available components -> Address >> OK
  5. ! You can save columns settings and later recall them from a list.

14

Inventory the internetwork's hardware and software using Desktop Manager's Query tool.

 

  • MW scanning applications:
    - LDISCAN.NLM (LDINV.NLM stores this information on specified inventory server)
    - LDISCAN.EXE
    - LDISCNNT.EXE
    - MacScan (MACIPXGW.LAN driver translates AppleTalk and IPX)
    - WLDISCAN.EXE
  • automatically collect hardware and software information about servers and workstations. the scanned data stored in a Btrieve database on a MW server can be accessed through MW Console's Desktop Manager. Inventory on PC not connected to network - merge with inventory database.
  • In Desktop Manager close default display of the inventory database by double-clicking the inventory server icon

Tools|Query

  • Select needed from Components list (Only previously discovered components and values are displayed)
  • You can edit query in Query Building Box
  • OK
  • View|Columns in order to see results.

! SYS:\MW\LDT\Changes.log is not enabled by default.

15

22

Create and use an SNMP profile to monitor a NetWare server.

 

  • MW can use SNMP MIB (Management Information Base) to monitor network and assist in creating alarms when problems occur.
  • SNMP MIB Browser (Tools|SNMP MIB Browser) show SNMP statistics of a selected device.
  • SNMP MIB Compiler (Tools|SNMP MIB Compiler) incorporates third-party MIBs into the MW SNMP configuration (C:\MW\NMS\SNMPMIBS\CURRENT is source folder, C:\MW\NMS\BIN\SNMPMIBS.BIN - compiled binary base)
  • SNMP MIB Compiler adds any traps contained in the MIB to MW alarm database.
  • Individual SNMP statistics are known as scalars.
  • Groups of SNMP statistics are known as profiles.

To create a custom profile for <server> 
- select <server> from a segment map
- launch SNMP MIB Browser
- click Add
- input Name, Description, click Polled, Scalar, add Scalar Attributes Choices, Save, OK

 

 

 

 

 

23

24

Create thresholds and set threshold delta values.

 

1.     Server alarms are used to monitor server performance. Many server alarms are available. Most are disabled by default; some are useful only in specific circumstances. Some thresholds, such as CPU Utilization, use averages to trigger alarms. Other thresholds use actual number counts.
a) For file servers, you might set thresholds for the following alarms:
- File Cache Hits (avg.%)
- Dirty Cache Buffers (avg.%)
- Cache Buffers (%)
- File System Reads (#/min)
- File System Writes (#/min)
b) For print servers, you might set thresholds for the following alarms:
- Ready Jobs in Queue (avg. KB)
- Ready Jobs in Queue (avg. #)
- Wait Time of Next Ready Job (sec)
c) For all type of servers, you might set thresholds for the following alarms:
- CPU Utilization (avg.%)
- Allocated Memory (%)

2.     Server Thresholds
- select a map with server
- select <server>
- Performance|Netware Server Thresholds
- Double-click parameter
- Click Graph button
- If possible, compare the current average value with your baseline

3.     You can use segment alarms to monitor and analyze traffic on a segment. All segment alarms are raising alarms. To prevent multiple alarms caused by the same condition, the statistics must fall at least 10% below the threshold value and then rise above the threshold again before the alarm can be tripped again.

4.     The available segments alarms include
- Packets
- Utilization (%)
- Broadcasts
- Fragments
- Jabbers

 

 

 

5.     Alarm Bells:
- Red bells signify critical alarms (on the left)
- Magenta bells represent major alarms
- Yellow bells denote minor alarms
- Blue bells indicate informational alarms

6.     Ticker messages at the lower left corner of MW Console

25

Record network segment trend data and set segment traffic thresholds.

 

  1. You must set a threshold value and a sampling interval for each segment alarm.
  2. Configure segment alarm:
    - On the internetwork map, select a network segment
    - Click the Trend Graph button (#7).

Observe the statistics to estimate current packets per second.
- Close the graph
- From the MW Console menu, select Edit|Database Object (Icon with123)

Section 9 = Troubleshooting Network Performance Problems

37

Describe possible performance issues as regarding network servers, LAN segments, and workstations.

 

1. Performance issues:
    - Another service request is monopolizing the server's resources
    - The server is being asked to provide too many services
    - The routers between WS and server are overworked, or too few alternate routes are

        available
    - Segments between the WS and the server are overloaded
    - The server configuration is not optimized for file I/O
    - The WS configuration is incorrect
    - A network connectivity device, or other device, has failed
2. Overworked servers
    - TrendComplete"s NW server health reports
    - Server Trend Graph (packet loads and system reads and writes)
    - Current number of active processes on the server (SNMP statistics)
    - Compare the current work load with baseline data
3. Overloaded Segments
     - TrendComplete"s network health reports
     - Segment Trend Graph (Total Packets/sec, Good Packets/sec, Error Packets/sec per 

        minute, hour, week, month, year)
     - Compare the current segment load with baseline data
     - All segments between WS and server
4. WS Configuration
      - hardware inventory query (CPU is slow?)
      - Control Station to examine Win 95 or Novell Client network configuration
      - SyncComplete's baseline reporting features can be used to determine the characteristics

          of WS on your network                 
      - Capture the packets sent and received by the WS during a file I/O transaction

 

38

Apply an SNMP MIB profile to a server and compare the data with baseline data to evaluate server performance.

 

1. Select <server> from a map
2. Launch SNMP MIB Browser
3. Run saved profile
4. Compare the data with baseline data

39
