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.

What I have posted is the only message I got:

The error "impossible de trouver ou charger la classe principale org.apache.hadoop.yarn.server .applicationhistoryservice. ApplicationHistoryServe" show the installation didn't go well could you simply remove the Service Ambari Metrics--->Service Actions---> delete service then confirm "delete"

Remove ambari-metrics-collector package

# yum remove ambari-metrics-collector

Reinstall ambari-metrics-collector

# yum install ambari-metrics-collector  

Add the service using Ambari

Start the ambari-metrics-collector using Ambari

Please let me know

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

Please revert

I removed the ambari metrics using Ambari UI, and I add that service but I still get the same error !!

I have this alert concerning the ambari metrics:

Connection failed: [Errno 111] Connection refused to datanode1.xxxx:6188

@Maryem Mary

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?
