AMBARI METRICS restart randomly

[#1]

Hi,

I built a new standalone hdp 2.3. This standalone are not yet sollicited by application but the ambari metrics service shutdown and restart for no reason. It can happen twice/three or four times a week.

This is the logs of my ambari-metrics-collector.log:

Do you know the reason of this restarts?

ambari-metrics-hadoop-sink-2.2.0.0-1310.x86_64

Could be memory issue.

Can you check /var/log/messages for Kernel OOM killer.

Also please give details of your environment. (OS, RAM, nodes etc)

[#5]

I have not memory issue ( No OOM Killer...).

I run a centos6 standalone server with 125G RAM.

My ams parameters values:

metrics_collector_heapsize: 1024MB

hbase_master_heapsize: 2048MB

hbase_regionserver_heapsize: 2048MB

[#6 · Accepted solution]

Could be because of https://issues.apache.org/jira/browse/AMBARI-15492. This has been fixed in the next Ambari release (2.2.2).

For a workaround please try commenting these 2 properties in /etc/ambari-server/conf/ambari.properties

#recovery.enabled_components=METRICS_COLLECTOR

#recovery.type=AUTO_START

Restart Ambari Server.

[#7]

It does not work if i comment those lines.

My ambari server still stop and now it does not start.

[#8]

Ok i restart ambari-agent too it seems good now. No alerts for 2 days.keep in touch ;).

Thanks
