Assumptions
25
– Installation has already been done• Installation Hints: Check all prerequisites especially kernel parameters,shared memory, semaphores, RAM, etc.
– This example is done on a Unix machine. Paths need to beconverted for Windows.
After the Install, Validate Processes Are Running
26
– At command line, run “ovstatus –c” for a basic check.
– Most processes are now within the ovjboss so you must alsorun “ovstatus –v” for the details of the jboss
services.
jboss Processes# ovstatus -v ovjboss

Initial Login
28
– Login with browser (no more java plugins required)
– http://myserver.example.com/nnm
– Initially log in with the system password created during installation
29
Create a new user
30
– It‟s best to create an administrator account rather than using
the system login
– Click on the Configuration Workspace and select User Interface configuration
31
– Click on the New Icon to launch the Account Mapping form
– Select the pull down menu to the right of the Account entry and select New. (It is a common mistake to try to simply type in the Account rather than creating a New one.)
32
– Type in the User Name and Password (we‟ll call ours “admin” and the
password will be “adminpw”)
– Select the role and hit save and close
33
– We now have an admin account
– Try logging out and back in with the new account.
You can see the userpresently logged in to this session in the
upper right.
34
Apply a License
35
– Product comes with a 250 node instant on license.You don‟t need to do anything to use this
license. But once you hit 250 nodes, no other nodes will be discovered or monitored.
– You can also obtain a temporary license from HP for initial trial.
– You can apply the license via a GUI usingnnmlicense.ovpl NNM –g
– Or via the command line usingnnmlicense.ovpl NNM -f ./ mylicense.key
Configure Communication– Go to the Configuration Workspace and select
Communication Configuration
36
– Select the Default Community Strings tab and click on the New icon.Enter all of your SNMP Read Community Strings here.
– Order does not matter. NNMi attempts all Comm Strings simultaneously and chooses the first one that succeeds.
– You can also modify the default timeout and retry attempts here. After making changes, save and close the form.
– SNMP „GetBulk‟ by default – recommended to be unchecked for end nodes
37
SNMP Management Address Discovery– Leave “Enable SNMP Address Discovery” unchecked if you
want to keep the same loopback address as the only address that will ever be tried for SNMP communication.
38
Discovery Configuration
39
– List based discovery (similar to loadhosts of legacy NNM)• More control
• No surprises
• Requires high level of knowledge of nodes
• Only name or IP is required. No subnet masks required
• Static data
– Auto-discovery (we‟ll use this for our example)• Always up to date
• Requires good “rules” to control breadth of discovery
• By default, NNMi only discovery switches and routers (this is easily expanded)
– Go to the Configuration Workspace and select Discovery
Configuration.
40
– Select the Auto-Discovery Rules tab and click on the New icon.
41
– Fill out the Basics section and click on the New icon for the IP Address Ranges in this rule. The value for Ordering doesn‟t matter in this case since we‟ll only have one auto-discover rule.
42
– Type in a range. A rule can contain multiple ranges.
– Choose the Range Type (Inclusive for our example)
– Save and close the forms.
– We now have a discovery rule for the 15.2.*.* subnet.
43
– Since we didn‟t enable “ping sweep”, we must provide a seed router to get thediscovery started.
– Add the name or IP address of a router in this subnet to begin the discovery
44
– NNMi uses the following sources of "hints":
45
• ARP cache• DNS• Ping Sweep if configured• BGP - Border Gateway Protocol• CDP - Cisco Discovery Protocol• EIGRP - Cisco Enhanced Interior Gateway Routing Protocol• ENDP - Enterasys Discovery Protocol (also known as CDP - Cabletron Discovery Protocol)
• FDP - Foundry Discovery Protocol• OSPF - Open Shortest Path First
– You‟ll now begin to see nodes get discovered. You can view the list of discovered nodes in many places in the GUI. Try the Network Overview under the Topology Maps workspace.
– Note that this is usually an abbreviation of the entire set of nodes.
– You can also see discovery progress using the following graphs:• Tools -> Self-Monitoring Graphs -> Discovery Progress
• Tools- > Status Distribution Graphs -> Node Status
46
Manual Seed Discovery– Recommended if you know your
network well– Create a seed file
• List of management IPs for all the nodes to be managed• One IP per line, comments followed by „#‟• Example: <IP address> # <DNS name>• IP goes under „Hostname/IP‟ field and DNS goes to „Notes‟ section
• „Notes‟ can later be filtered for troubleshooting based on hostnames
– nnmloadseeds.ovpl –f <seedfile>
47
Manual Seed Discovery (cont.)
48
– Rediscovery interval 24 hrs by default
– Load the nodes across 24 hrs so that discovery goes across the cycle• For example, for loading 3000 nodes manually using a seed file:
– Load 300 nodes at a time every 3 hrs overnight (evening to next day morning)
– Ensures that CPU spikes for NNMi server are not occurring daily at the same time
29
Interface Discovery Filter
– Now supports interface filters for discovery
– Based on the interface groups
– Interfaces passing this filter do not get added during discovery of new nodes
– For already existing nodes, next scheduled or manual config poll takes care ofremoving the filters from the topology
Monitoring Configuration
50
–Default Behavior• NNMi monitors “connected” interfaces where connected means the interface has a discovered connection to another interface in NNMi. Most access switch ports would not be considered connected if you don‟t discover end nodes. Instead typically the uplink would be monitored.
• NNMi does ICMP monitoring of management addresses• You may not need to make any additional changes
– Example of monitoring the uplink
51
Steps to Modify Monitoring
– The basic steps to modify the monitoring in NNM include:• Create a node group and/or interface group• Associate a monitoring setting (polling policy) with the group• Prioritize the monitoring setting (nodes and interfaces can match multiple groups)
(by default “connected” interfaces and management addresses)
52
– Suppose that we have some nodes with an IfAlias that begins with “tunnel to”.
– We have been instructed that these interfaces need to be monitored if their speed is also 9 Kbs.
– We‟ll need to create a filter to identify any interfaces that match this criterion.
– Then we‟ll apply a polling policy to these interfaces.
53
Creating an Interface Group– Under the Configuration Workspace, select Interface Groups
54
– Click on the New icon
55
– Name the new Interface Group
– Create the filter expression using the logical operands
– Save the Interface Group
– Test the membership with Actions -> Show Members
56
New Filter Operators
57
– “Not” operator
– “Exists” and “Not Exists” allow filters to be created with expected results when combining multiple custom attributes or capabilities• (hostname like router*.hp.com OR EXISTS((customAttrName=edgeAND customAttrValue=true)))
– Results of the membership test
– Watch out for any “stale” filters on this view that might be inadvertentlyapplied
58
Apply a Polling Policy to the Interface Group– In order to poll the interfaces defined by this filter, we
must apply a polling policy to this group.
– Open the Monitoring Configuration view
59
– Since we defined an Interface Filter, select the Interface Settings tab
– Note the current “ordering” values
– Click New
60
– Select the Interface Group and enter in an Ordering value
– We want it to be “higher” than the other policies (lower number)
– Extend the polling beyond connected interfaces
– Save and Close the form
61
Testing the Polling Policy
– Identify the selected interfaces (We‟ll select Inventory->Interfaces and choose our filter in the pull-down menu.)
– Open one of the interfaces
– Select Actions -> Monitoring Settings
62
– Validate the Interface Group policy that is applied
– Validate that the interface is being polled
63
Making Exceptions to Polling
– Most polled objects can be Unmanaged or set to Out of Service
64
Custom Poller
65
– Can configure polling to monitor MIB information not monitored by default
– Enhanced in 9.0 to support MIB Expressions
– Setting Up Your MIB• Step 1: Identify the MIB Variable You Want to Poll• Step 2: Ensure the MIB Includes Supported Types• Step 3: Load the Required MIB• Step 4: Use an SNMP Query to View Current MIB Variable Values
– Setting Up a Custom Poll• Step 1: Enable Custom Poller• Step 2: Create a Custom Poller Collection• Step 3: Create a Policy for a Custom Poller Collection
– Examine the Results of Your Custom Poll• Step 1: View the Custom Node Collections Associated with Custom Poller Policies
• Step 2: View Details of a Custom Node Collection• Step 3: View Details of a Polled Instance• Step 4: Evaluate the Results of the Custom Poll
MIB Browser– Do an SNMP query to get current values
66
Enable Custom Poller– Click on “Enable Custom Poller” to enable
67
Create a Custom Poller Collection
68
Create a MIB Expression– See the animation in the online help for a demo on creating a MIB expression
