Did you know? Explore the possibilities with HP Network Node Manager (NNMi)…


In a typical enterprise, it is common to have the Line of Businesses (LoB) questioning the IT Operations for any service outage the LoB faces. In the end, the networks are usually blamed for any outages—which is why network management is key. HP Network Node Manager (NNMi) 10.00 has been out for almost a year now, and I am quite sure many of you already know what's new in this version of NNMi (You can read a refresher here). However, I have interacted with many consultants and practitioners that have a constant need to provide HP NNMi’s business value proposition to their end clients.

This is especially true in cases where IT Operations requires a software suite that can help them defend the LoB when blame is placed on IT for any network fault or performance issue.


In this blog, my idea is to describe some of the use cases that HP NNMi software suite can help you with to:

  1. Position the business value of these products
  2. Help the IT Operations respond to the concerns raised by the Line of Business

A million dollar question in monitoring: Is it a device or a network downtime?


One of the biggest concerns in a typical enterprise IT office is to figure out the real reason behind an unavailable network entity. Is the network always to blame? I recently worked with an enterprise customer with many of their network devices in remote branch offices. They were getting power supply only from the Uninterrupted Power Supply (UPS) - that is, no main supply for the devices.


In such a case, it becomes important to know what the device unavailability is attributed to – UPS shutdown (failure or dried battery) or network connectivity? NNMi Premium’s Metrics iSPI helps you get an answer to questions like this by clearly differentiating a device downtime (device is unavailable due to reboot or shutdown) from a network downtime (device available but is not reachable) as part of performance monitoring and reporting functionalities.


Have you ever thought of monitoring traffic flowing through the "traffic" cameras?


 I am sure most of you know that the government in many countries use CCTV cameras to track traffic and anti-social or criminal activities in big cities. While this is common, how cool would it be if you could manage the CCTV camera infrastructure and proactively alert users on any outage or about high-volume traffic in certain areas? Yes, with NNMi Ultimate - this is a possibility. With the latest technologies, CCTV cameras can directly talk IP and can be monitored for availability. Moreover, with IP flow (e.g., netflow, sflow) traffic characterization capabilities in NNMi Ultimate’s Traffic iSPI, users can map traffic flowing through the camera infrastructure to a friendly name to characterize the traffic as “known traffic”. This capability helps the user proactively manage the capacity of the camera infrastructure by monitoring and reporting the link bandwidth utilization in the context of known traffic.


 Slow transactions at bank ATMs? Dig deeper to find the cause…


After the banking industry transformation, how many of us still go to a bank to withdraw cash? Almost 99 percent of urban population is using Automated Teller Machines (ATMs) for cash withdrawals as well as many other banking transactions. This is why it is important for the banks to assure good service levels to their customers at ATMs.


In a typical network setup, an ATM machine is connected to an on-premise access switch and that switch is usually connected to a nearby branch office or headquarters (HQ). Network latency – from headquarters or branch to ATM device - is one of the key service measures for this infrastructure. This can also be accomplished by setting up SLA tests running from branch/HQ to ATM device. NNMi Premium’s Quality Assurance iSPI leverages the power of these SLA measurement technologies (e.g., Cisco IP SLA tests) to provide both real-time and historical monitoring of service parameters like network latency (RTT – Round Trip Time), jitter and packet loss.


Want to migrate services from On-Premise to Cloud? Need help in capacity management?


With cloud service platforms maturing, more and more enterprises are moving their services from on-premise to the public or private cloud. I worked with a customer who has a business need to move the site-local application traffic to the cloud (for example, MS Exchange services from local site to MS 365 Cloud service). In this case, it became important to understand the bandwidth utilized by the site-local applications in terms of what percentage of application traffic is carried by the MPLS WAN links vs. Internet links. NNMi Ultimate’s Traffic iSPI captures these details which eventually helps in capacity management of these WAN links. For example, it helps free up bandwidth from high capacity and high cost MPLS WAN links and route the same traffic through Internet links. This capability enables customers to add more site-local capacity on existing MPLS links and save the new MPLS link provisioning cost.


Want to measure SLA for services hosted on the cloud?


On the similar lines of the above use case, once the services are hosted on the cloud, the immediate question is: Am I getting what I am paying for? This is when SLA measurement becomes an important aspect. With NNMi Premium’s Quality Assurance iSPI, one can measure the SLA like network latency over the WAN link – for example, from an enterprise network to the cloud device hosting the service - irrespective of the management scope of the cloud device.






 Bad call quality? Need voice quality monitoring?


With a majority of enterprises going with VoIP, it is not a surprise when a customer asks about monitoring missing dial-tone and voice quality issues in the network. With the same network being used for carrying voice and data traffic, it also becomes important to manage the capacity of the network in terms of utilization and peak-hour usage of telephony infrastructure. With NNMi’s IP Telephony iSPI, one can monitor the voice quality in terms of latency, jitter, packet loss and MoS parameters. These measurements can be configured for threshold violations to get alerts on call quality, graphed for real-time troubleshooting and can be reported for historical data analysis and capacity planning. Apart from these, telephony infrastructure (Voice Gateways, Voice Channels, Trunks etc) utilization can also be monitored and reported using the iSPI.


Subscribers facing video quality issues during CxOs' talk? Nail it down…


Most of the big enterprises today have Webcasts hosted by their senior executives (CxOs) be it quarter results or organizational updates or all-hands meetings. How annoying would it be to have an important update occurring and subscribers from certain site are experiencing video degradation issues – like broken video footage or unsynchronized voice and video as a result. With NNMi Ultimate’s IP Multicast iSPI, one can monitor such live video and webcasts for quality of service issues – provided that the video being telecast runs on a multicast-enabled infrastructure. The SPI helps users visualize the complete topology from publisher to subscriber and enables users to pinpoint the segment of the network that is the root cause for video degradation issues faced by the subscribers of certain site(s).

 Bad call quality? Need voice quality monitoring?

I have one question on above subject iSPI for IPT from last para--"Apart from these, telephony infrastructure (Voice Gateways, Voice Channels, Trunks etc) utilization can also be monitored and reported using the iSPI."

Does iSPI for IPT is capable to monitor both fault/performance of Cisco SIP trunk up/dpwn status?

As per guide “nnm_ispi_IP_Telephony_OnlineHelp_Reports_Cisco_10.00” page 95---The NNM iSPI for IP Telephony provides the Cisco IPT SIPTrunk Session extension pack to view and analyze the performance data of the Cisco IP telephony environment. You can use this extension pack to generate reports for the monitoring of the SIP Trunk Session on the UCMs and the SIP trunks based on the call activity metrics such as the number of Calls Active, Calls Attempted, Calls Completed and Calls in Progress.
