Netcool in general is alive and getting better, but if you think it is the best and nothing can be improved, then we'll kill the software slowly.
Here is my list of things to be improved:
DASH: It is a Gigas' software just to show dashboards. Custom dashboards are hard to maintain or edit, and its HA could be improved (now db tables must be dropped and recreated offtenly because .xml files error synch, or just corrupted data). I miss something "grafana style" (I know grafana is for timeseries, but some kind of integration could be done). Keep in mind that grafana is a simple .rpm around 50 MB.
HA for Gateways.
Impact: Add real development environment for easy debugging. Also include default external integrations for Slack, PagerDuty, Rundeck, and so on, instead of developing policies for all.
TCR: 3 additional GB to generate reports! Why? Not very welcome at customers. We need something light, easy, fast.
Generate html/pdf/csv reports that could be sent by email easily without deploying .ear files and so on.
Integrate in the same possible future "human interface" Monitoring and Maps with nodes relationship (call it ICD-CMDB, TADDM...). From time to time is healthy to take a look to our competence, and SN! we have to recognize is doing this pretty good.
Simplify Netcool "get in touch": Let me explain about this general point.
It is simply a mess for a customer to get latest versions of Probes (names are confusing, ie: CA Spectrum Probe versions), or they way to download products (ie: find the correct PartNumber or... are WAS additional and TCR images required? If you are new on netcool, it is not an easy stuff).
I've seen a lot of youtube videos explaining installations and integrations. I think this is a very good way to spread netccool solutions, and we could do it officially.
So in summary... long life for Netcool means close control and constant effort/investment from our side.
