We have tested the embeded mode to work with upto 400 node cluster and mult= iple services running on it.

You can change the hbase.rootdir in ams-hbase-site and possibly write = to partition with separate disk mount.

And copy over the data from existing location. It would be good to kno= w what is the size of data written to hbase.rootdir to get an idea of what = kind of write volume are we looking at.

How big is your cluster in terms of number of nodes?
You can tune settings for HBase based on cluster size.

Following are the instructions for writing metrics to HDFS instead of = local FS.

ams-site:::
timeline.metrics.service.operation.mode =3D distributed

ams-hbase-site:::
hbase.rootdir =3D hdfs://<namenode-host>:8020/amshbase

Hi Siddhart= h,

Yes, I am using&n= bsp;Ambari 2.0 with Ambari Metrics service.
The interesting thing is that I g= ot them for some time and not anymore.
And I also know that the metrics = are being collected since i can see them on the dashboard.
Any pointer= for troubleshooting?

And btw, it would be nice to have a count of messages received a= nd not a computed metric count / min.
TSDB does a good job of giving me= cumulative and rate-per-sec graphs and numbers.

Thanks in advance= ,
Jayesh

Hi,

I have installed = 2 clusters with Ambari and Storm and Kafka.
After= the install, I was able to get metrics for both Storm and Kafka via REST A= PI.
This worked fine = for a week, but since the past 2 days, I have not been getting Kafka metric= s.

I need the metric= s to push to an OpenTSDB cluster.
I do = get host metrics and Nimbus metrics but not KAFKA_BROKER metrics.

I did have mainte= nance turned on for some time, but maintenance is turned off now.
