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 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
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?

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,
