ambari rest api for metrics

amol_08 — Tue, 20 Feb 2018 14:54:39 GMT

Is there rest api which can fetch all the details what metrics monitors collects or metrics collector does ?

Thanks in advance

There is not Rest API call which can be used to capture the whole Metrics Monitors/Collectors Data in form of a file.

However you can query these data from the AMS collector Hbase database using utilities like sqlline as desceribed in

As mentioned on the other thread: https://community.hortonworks.com/questions/172151/data-source-for-ambari-metrics-collector.html?childToView=173755#comment-173755

is there some way I can get data what metrics monitor collect system-level metrics and publish to the Metrics Collector.

other than using sqlline .

where does metrics monitor collects system level metrics ?

However one thing you can try:

You can make the following API call to query individual Host metrics for a specific time range.

example:

# curl -v "http://amb25102.example.com:6188/ws/v1/timeline/metrics?metricNames=bytes_in._rate._avg&hostname=&appId=HOST&instanceId=&startTime=1451630974&endTime=1519110315"

However in this case you will need to keep changing the metrics name like "byte_in" ....

The time range you can take longer like "1451630974" means starting from 1 Jan 2016 , till "1519110315" means now.

NOTE: However as mentioned earlier there is no Single API call that can be used to fetch all the AMS collector data.

You can use Grafana to get the Host Level metrics which are sent by Ambari Metrics Monitor to Ambari Metrics Collector, By creating a custom dashboard. (Still it will be in form of Graph and not a single file with whole data)

Like: In following case i created a New Dashboard with "HOST" metrics and the metrics name is "byte_in" with Aggregator as "avg"

Some of the metrics list you can find here that are exposed to the AMS collector:

For All kind of metrics:

https://github.com/apache/ambari/tree/release-2.6.1/ambari-server/src/main/resources/common-services/AMBARI_METRICS/0.1.0/package/files/service-metrics

For particularly host specific metrics names you can refer to:

https://github.com/apache/ambari/blob/release-2.6.1/ambari-server/src/main/resources/common-services/AMBARI_METRICS/0.1.0/package/files/service-metrics/HOST.txt

Hi Jay,

curl -v "http://amb25102.example.com:6188/ws/v1/timeline/metrics?metricNames=bytes_in._rate._avg&hostname=&appId=HOST&instanceId=&startTime=1451630974&endTime=1519110315"

This rest api not working for For All kind of metrics:.

I have replaced bytes_in._rate._avg to master.Server.numDeadRegionServers

curl -v "http://amb25102.example.com:6188/ws/v1/timeline/metrics?metricNames=master.Server.numDeadRegionServers&hostname=&appId=HOST&instanceId=&startTime=1451630974&endTime=1519110315"

but not able to get the metrics results .
