Subject: 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<https://gcc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fcrosswork.cisco.com%2F%23%2Fconfiguration&data=02%7C01%7Cjamann%40mt.gov%7Cad0e7d34170c4c4c5ba308d6d91b24f6%7C07a94c98f30f4abbbd7ed63f8720dc02%7C0%7C0%7C636935107944493959&sdata=bdDTxnmNMYK1CerIUqB%2BdmyjWZbIPZHyIKei3ocU%2Ffk%3D&reserved=0> 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: https://portal.bgpmon.net/myprefixes.php<https://gcc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fportal.bgpmon.net%2Fmyprefixes.php&data=02%7C01%7Cjamann%40mt.gov%7Cad0e7d34170c4c4c5ba308d6d91b24f6%7C07a94c98f30f4abbbd7ed63f8720dc02%7C0%7C0%7C636935107944493959&sdata=BJ5gv1z3Olqa25%2FAN49vAf5g3Ay4BA2DVLNcLJB8nWo%3D&reserved=0>
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<https://gcc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fportal.bgpmon.net%2Fmyasn.php&data=02%7C01%7Cjamann%40mt.gov%7Cad0e7d34170c4c4c5ba308d6d91b24f6%7C07a94c98f30f4abbbd7ed63f8720dc02%7C0%7C0%7C636935107944503949&sdata=TzGEF2aobeKBpPsA89XAZAUYNrDVtPsmJvnVL2A71JM%3D&reserved=0> is non-existent in CNI.
Or how about the alarms one gets to an email?  Want to see how that looks?

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?
Disappointed,
Hank
