HY
Senior System Administrator at Interactive Group
Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Provides deep packet visibility for tracing failed transactions and helps improve enterprise-level monitoring
Many improvements are needed for Riverbed NPM+, particularly in NetIM, which does not perform as well as SolarWinds' single module NPM solution. Additionally, within Riverbed Portal, there is an Application Map module that could be improved. It can show the application's architecture and connectivity to the network. The applications map feature needs enhancements for better customization since currently, it is quite limited. The enhancements I recommend are not for the entire Riverbed product suite, but specifically for the application map feature within the Portal of Riverbed NPM+. This Portal is one of the dashboard modules and while there is potential for improvement, it must be enhanced significantly to provide better functionality. Currently, you cannot trace by transaction number alone; knowing the source and destination IP is necessary. For instance, if I transfer money and a transaction fails, tracing that transaction ID is not captured in AppResponse. I have raised this concern, and if this feature is implemented, it would greatly benefit banking customers, especially because it is not available with their competitors either.
