Upgrade Ambari Metrics

If you have Ambari Metrics installed, you have some manual steps to perform as part of the upgrade. Upgrading Ambari Metrics involves ensuring that it is in Maintenance Mode, upgrading the Metrics Collector, and upgrading the Ambari Metrics Grafana component.

1. Confirm that Ambari Metrics service is stopped and in Maintenance Mode.

   If Ambari Metrics service is not stopped, from Ambari Web, browse to Services > Ambari Metrics and select Stop from the Service Actions menu.

2. On every host in your cluster running a Metrics Monitor, run the following commands:

   For RHEL/CentOS/Oracle Linux:

   yum clean all

   yum upgrade ambari-metrics-monitor ambari-metrics-hadoop-sink

   For SLES:

   zypper clean

   zypper up ambari-metrics-monitor ambari-metrics-hadoop-sink

   For Ubuntu/Debian:

   apt-get clean all

   apt-get update

   apt-get install ambari-metrics-assembly

3. Execute the following command on all hosts running the Metrics Collector:

   For RHEL/CentOS/Oracle Linux:

   yum upgrade ambari-metrics-collector

   For SLES:

   zypper up ambari-metrics-collector

   For Ubuntu/Debian:

   apt-get clean all

   apt-get update

   apt-get install ambari-metrics-collector

4. Execute the following command on the host running the Grafana component:

   For RHEL/CentOS/Oracle Linux:

   yum upgrade ambari-metrics-grafana

   For SLES:

   zypper up ambari-metrics-grafana

   For Ubuntu/Debian:

   apt-get clean all

   apt-get update

   apt-get install ambari-metrics-grafana

   	Note
