Ambari performance issue

prakashpunj — Fri, 16 Sep 2022 12:20:09 GMT

Need help in troubleshooting the performance issue. Every little things on Ambari, starting from logging in to Navigating , to make configuration changes is extremely slow and sometime it also times out. NameNode/Ambari-server has 32GB and other node in the cluster are 16GB and 8 GB and have no load. What may be causing this behaviour..

@Prakash Punj

You can refer to the following article which explains some very common areas to look for when we see the Slowness on Ambari: https://community.hortonworks.com/articles/131670/ambari-server-performance-tuning-troubleshooting-c.html

If your Ambari Cluster is bit old then it is highly possible that the DB size has grown a bit, So many times "db-cleanup" helps to improve the performance much.

From Ambari 2.5.2 Onwards: From Ambari 2.5.2 onwards the name of this operation will be changed to "db-purge-history" and apart from the Alert related tables it should also consider of other tables lie host_role_command and execution_commands and if there is any other tables as well.

# ambari-server db-purge-history --cluster-name Prod --from-date 2017-08-01

See: https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.2.0/bk_ambari-administration/content/purging-ambari-server-history.html
