Time to Threshold and Time over Threshold help reduce event noise to a level that operation teams can manage.Parts of the Unified Management Portal are not written in HTML5. I would like all components (Portlets) to be HTML5. This would increase the speed and responsiveness of the site, and possibly improve the appearance. Improved network monitoring and topology mapping: Although this functionality does exist, it requires enhancement. CA UIM is very accomplished at monitoring the majority of IT infrastructure and is capable of collecting and alerting on the vast majority of metrics across network device vendors. However, the configuration of network device monitoring could be improved. The latest SNMP_Collector, and ICMP (ping) probes only allow for monitoring of discovered devices and are configurable via the web-based Admin Console. The previous equivalent probes were less dynamic but more flexible, being configured via both the Admin Console and the client-based Infrastructure Manager. A combination approach of dynamic and manual network device monitoring would obviously be more beneficial. As for network topology mapping, this is achieved via disparate pairs of discovery_agent and topology_agent probes located in each network segment gathering device information via ICMP, SNMP, Telnet and SSH. This mechanism actually works really well, but it’s the way the data is collated, interpolated and represented in the topology views which requires attention. Having some predefined views to depict different network layers, the ability to show routing of traffic or bandwidth utilisation would be great. Also, it would be nice if more detailed device information was available via a mouse-over. Note: I have not used the topology mapping in UIM 8.4, but I’m not aware of any significant improvements.
