@Angel Kafazov We need to look at the Master, RS and ZK logs to identify the issue. Can you upload them from /var/log/ambari-metrics-collector/ ?

Please revert back the znode setting to default, if cluster is not kerberized: /ams-hbase-unsecure Also, make sure the quorum value in ams-hbase-site is: hbase.zookeeper.quorum {{zookeeper_quorum_hosts}}

KAFKA and STORM default dashboards are in the works and targeted for 2.4.0 However you can start visualizing these metrics with custom dashboard from 2.2.2 itself.

Ambari 2.2.2 comes with built in Grafana integration so you can build a dashboard of you choice. All metrics are self discovered and no extra steps are required. Adding Grafana: https://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.0/bk_upgrading_Ambari/content/_adding_grafana_to_ambari_metrics.html Grafana docs: http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.0/bk_Ambari_Users_Guide/content/_using_grafana.html The Ambari widgets provide a service level aggregated view of the service metrics. You would need to update the metrics.json file from "/var/lib/ambari-server/resources/stacks/HDP/2.3/services/KAFKA/metrics.json", this overrides the common-services definition for HDP versions 2.3+ And then add widget from Ambari. Docs for that: https://cwiki.apache.org/confluence/display/AMBARI/Enhanced+Service+Dashboard

Trying cleaning up Zookeeper state and restarting, rarely due to improper shutdown in embedded mode the state gets corrupted: Check value of hbase.tmp.dir, default = /var/lib/ambari-metrics-collector/hbase-tmp/ rm -rf /var/lib/ambari-metrics-collector/hbase-tmp/zookeeper/zookeeper_0/version-2/* Restart service.

The Start All/Stop All works just the same although there is a slight delay in updating the state which would mean stae alert not cleared immediately. I believe we send config tags from the agent only after a certain number if heartbeats. However, what you have in the scrip is exactly what the UI does, so that should work just fine. (+1)

Unfortunately this is not a part of the release branch. The patch is committed to trunk and scheduled for 2.4.0. https://issues.apache.org/jira/browse/AMBARI-14394

Starting 2.2.2, AMS has a new API to discover metrics that can be accessed as: http://<ams-host>:6188/ws/v1/timeline/metrics/metadata Note: These metrics are available to be visualized using Grafana starting 2.2.2

If there is a local Datanode consider switching to AMS distributed mode, which means AMS will write to HDFS. https://cwiki.apache.org/confluence/display/AMBARI/AMS+-+distributed+mode Note: In distributed mode, HBase master needs much less memory vs RS, example say you have a 50 node cluster consider these memory settings: ams-env :: collector_heapsize = 2048 ams-hbase-env :: hbase_master_heapsize = 512 ams-hbase-env :: hbase_master_xmn = 102 ams-hbase-env :: hbase_regionserver_heapsize = 4096 ams-hbase-env :: regionserver_xmn_size = 512
