Cisco Crosswork Network Insights - or how to destroy a useful service

I have started to use Cisco Crosswork Network Insights which is the
replacement for BGPmon and I am shocked at how Cisco has managed to
destroy a useful tool.I have had a paid 50 prefix account since the day
BGPmon became available and helped two clients implement a 500 prefix
license over the past 4 years.None will be buying Cisco Crosswork
Network Insights, based on my recommendation.
I really don’t know where to begin since there is so much to dislike in
this new GUI.I will try to give you just a small taste but I suggest you
request a 90 day trial license and try it out for yourself.
This was not designed by someone who deals with BGP hijacks or who
manages a network.It was probably given to some GUI developer with a
minimal understanding of what the users needed.How do I know this?Take
for example the main configuration menu:
https://crosswork.cisco.com/#/configuration with the first tab of
“prefixes”.On that page there is *no* mention of which ASN the prefix is
associated with.That of course was fundamental in the BGPmon menu:
Or take for example its “express configuration”, where you insert an ASN
and it automatically finds all prefixes and creates a policy.But does it
know the name of the ASN?Nope.Something again that was basic in BGPmon
via: https://portal.bgpmon.net/myasn.php is non-existent in CNI.
Or how about the alarms one gets to an email?Want to see how that looks?

Compare that with what we used to get:

Mark as false alert:https://portal.bgpmon.net/fp.php?aid=830521190
That is just a small sampling.Maybe two years down the road, Cisco will
speak to customers first before destroying a useful service.
Anyone else trying this out and feels the same or feels differently?
