------------------------------------
Summary: No metrics returned by Ambari REST API
Key: AMBARI-14102
URL: https://issues.apache.org/jira/browse/AMBARI-14102
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.1.0
Environment: HDP 2.2 + HDP 2.3 clusters
Reporter: Hari Sekhon
The REST API doesn't seem to return metrics for various clusters:
{code}
curl -u admin:<password>
'http://<hostname>:8080/api/v1/clusters/myCluster?fields=metrics/load'
{
"href" :
"http://<hostname>:8080/api/v1/clusters/myCluster?fields=metrics/load",
"Clusters" : {
"cluster_name" : "myCluster",
"version" : "HDP-2.2"
}
}
{code}
That example is taken straight from the documentation at:
https://cwiki.apache.org/confluence/display/AMBARI/Ambari+Metrics+API+specification
Adding the time range to the end doesn't seem to help even when updating the
epoch end range for current timestamp.
{code}[1430844925,1448633316,15]&_=1448633316000{code}
The Metrics collector is definitely running and has been for some time.
I've even tried this on 2 different clusters, one HDP 2.2, one HDP 2.3 as well
as the HDP 2.3 sandbox with the same result. The Ambari UI shows the graph for
average load under Ambari metrics service summary page so the metric is
definitely collected but the REST API still returns no results. Is this a bug
or am I missing something else?
