Could you share the full stacktrace? Maybe it's in ambari-metrics-collector.log. Also if you have non localized exception messages that would be helpful.

It's important to always describe your environment, this gives members a clearer picture. Having said that if you deleted the service as I had earlier indicated above.
You should be able to add the Ambari Metrics using Ambari UI--->Admin--->Stack and Versions--->Ambari Metrics add service. Make sure you have hbase installed as AMS uses it as for backend storage.
For Ubuntu you could check the availability of the packages as suite
# apt-cache showpkg ambari-server # apt-cache showpkg ambari-agent # apt-cache showpkg ambari-metrics-assembly

AMS collector is not starting please could you check the following logs for any detailed error or warnings:
# less /var/log/ambari-metrics-collector/ambari-metrics-collector.log # less /var/log/ambari-metrics-collector/ambari-metrics-collector.out
Is it possible to share these logs?
