@Krupal Jagtap You can use the Ambari API approach to delete the AMS monitor component. Example: # curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE http://hdfcluster1.example.com:8080/api/v1/clusters/TestCluster/hosts/hdfcluster3.example.com/host_components/METRICS_MONITOR . Here "hdfcluster3.example.com" is the host from where we want to delete the Metrics Monitor. "hdfcluster1.example.com:8080" is ambari server host & port. "TestCluster" is the cluster name. Please replace these values accordingly. Once it is deleted .. it is better to clean the "/etc/ambari-metrics-monitor" directory from that host. And it is also better to take a backup of the mentioned directory and then move it. # mv /etc/ambari-metrics-monitor /etc/ambari-metrics-monitor_BKP # mv /usr/lib/python2.6/site-packages/resource_monitoring /usr/lib/python2.6/site-packages/resource_monitoring_BKP . Then freshly reinstall the monitor from ambari UI on this host. ... View more

@Alexander Schätzle Also please check your KDC configuration to verify if it has default setting something like following or not? # cat /var/kerberos/krb5kdc/kdc.conf max_life = 24h 0m 0s max_renewable_life = 7d 0h 0m 0s default_principal_flags = +renewable, +forwardable . ... View more

@Krupal Jagtap The following error might occur if you have installed a slightly different version of Ambari Metrics Monitor compared to the ambari version and hence there are some library mismatch. [WARNING] emitter.py:74 - Error sending metrics to server. 'NoneType' object has no attribute 'strip' 2 . Please check the output of the following command and verify if all the ambari component versions are same? # rpm -qa | grep ambari . Better to freshly try installing the ams monitor. From ambari UI just remove the metrics monitor process and then try installing it again. ... View more

@Krupal Jagtap Good to know that now at lease the AMS monitor is coming up. Regarding the "No data available" issue please share the "/var/log/ambari-metrics-monitor/ambari-metrics-monitor.out" Also please check if the "/etc/ambari-metrics-monitor/conf/ambari-metrics-monitor.ini" file is pointing to the Correct Hostname of AMS Collector? ...

@Krupal Jagtap AMS monitor should come from Ambari repo (not from HDP repo) so please check if you have the amabri.repo file present on that host or not? # cat /etc/yum.repos.d/ambari.repo . If not then please copy and paste that repo file from ambari-server host to this host. Also please make sure that the host where the AMS monitor installation is failing does not have any N/W issue. THis is to ensure that the yum installation for AMS monitor happens without any issue. ... View more

@Krupal Jagtap The following error indicates that somehow the yum installation is not happening: Fail(err_msg) resource_management.core.exceptions.Fail: Execution of '/usr/bin/yum -d 0 -e 0 -y install ambari-metrics-monitor' returned 1. Error: Nothing to do stdout: . So can you please try to do the manual installation of monitor Binaries on that host as following and then continue from Ambari Server UI. # yum clean all # yum remove ambari-metrics-monitor # yum install ambari-metrics-monitor . Sometimes incomplete transaction at yum level causes such issue so better to remove the incomplete binary installation first and then try installing it again. Also please check if the "/etc/yum.repos.d/ambari.repo" file on that host is pointing to the correct repo URL and that URL is accessible from the host ? # cat /etc/yum.repos.d/ambari.repo # cat /etc/yum.repos.d/ambari.repo | grep baseurl . ...
