Network Node Manager i (NNMi) provides a rich set of out of the box dashboards for operational troubleshooting and network health indicators for operators to improve their network monitoring. However, every deployment is driven by a different KPI and there is a need for complementing dashboards that provide business value.
This blog post will demonstrate how to use an example dashboard which extends NNMi capabilities and provide a business value to higher management. If this dashboard was built using Business Value Dashboard software, then executives will have a concise view of network health using the variety of devices [Laptop or handheld] at any given point of time. These dashboards can also provide information from multiple sources (for example NNMi, NA, OMi etc.)
Network at Glance: Business Use Case illustrated
Below is the Network at Glance BVD dashboard, which provides a concise network health for each region and gateways on a single pane.
This dashboard provides business takeaways including what regions are facing any major outages and what region needs attention. It also provides information on any gateways which may need attention
Here is the description of various data points that are available on the dashboard:
- Number of devices in the region
- Pie-Chart showing number of devices in different severity level.
- Number of Critical, Major and Other incidents coming in last 24 hours
- Number of open Critical and Major incidents from nodes in this region
- Number of Gateways in overall network
- Pie-Chart showing number of gateways in different severity level
- Total number of Interface Utilization violations in last 24 hours
- Total Number of Gateway reboots reported in last 24 hours
- Maximum number of times any gateway rebooted in last 24 hours
A. Data from NNMi is fetched using Java SDK client. However, a client can use any of exposed interfaces by NNMi.
B. Convert NNMi data into a format supported by BVD (e.g. JSON format).
C. POST this data to BVD using HTTP or HTTPS.
D. Whenever a dashboard is launched, BVD draws the dashboard using the data received from NNM.
This dashboard keeps refreshing as BVD receives the data from NNMi
