Hi Jongchul,


Can you check for/post errors if any in either :


/var/log/ambari-metrics-collector/hbase-ams-master-<metrics-collector-host>=
.log

/var/log/ambari-metrics-collector/ambari-metrics-collector.log


Also, make sure "ps aux | grep ams" on the Metrics Collector shows 3 proces=
s (I am assuming that this is default deploy, so AMS operation mode =3D emb=
edded)


-Dproc_master

-Dproc_timelineserver

/usr/lib/python2.6/site-packages/resource_monitoring/main.py


All for user ams.


Another simple check is if Metrics Collector is listening on 6188:

#] netstat -anp | grep 6188


-Sid

ari-server instance from image on Google Cloud Platform

Hi.

I have encountered some issues about Ambari Metrics.

I have 6 nodes cluster on Google Cloud.

ambari master - 1 node
ambari agent - 5 nodes

Some metrics information disappeared after the ambari-server instance recre=
ation from image.

Attached file is tcpdump and Ambari UI screen shots. The tcpdump messages i=
ndicate that  there are a lot of checksum errors.


1. Is it problem related with checksum?

2. Should I reinstall Ambari Agent again?

Regards..

Jongchul
