Hi Bryan,
Few things you can do: 1. Turn on DEBUG mode by changing log4j.properties at, /etc/ambari-metrics-collector/conf/ This might reveal more info, I don't think we print every metrics received to the log in 2.0 or 2.1, I did add this option if TRACE is enabled to trunk recently. 2. Connect using Phoenix directly and you can do a SELECT query like this: SELECT * from METRIC_RECORD WHERE METRIC_NAME = '<your-metric-name>' order by SERVER_TIME desc limit 10; Instructions for connecting to Phoenix: https://cwiki.apache.org/confluence/display/AMBARI/Phoenix+Schema 3. What API call are you making to get metrics? E.g.: http://<ams-collector>:6188/ws/v1/timeline/metrics?metricNames=<your-metric-name>&startTime=<epoch>&endTime=<epoch>&hostname=<hostname> -Sid ________________________________ From: Bryan Bende <[email protected]> Sent: Friday, July 24, 2015 2:03 PM To: [email protected] Subject: Posting Metrics to Ambari I'm interested in sending metrics to Ambari and I've been looking at the Metrics Collector REST API described here: https://cwiki.apache.org/confluence/display/AMBARI/Metrics+Collector+API+Specification I figured the easiest way to test it would be to get the latest HDP Sandbox... so I downloaded and started it up. The Metrics Collector service wasn't running so I started it, and also added port 6188 to the VM port forwarding. From there I used the example POST on the Wiki page and made a successful POST which got a 200 response. After that I tried the query, but could never get any results to come back. I know this list is not specific to HDP, but I was wondering if anyone has any suggestions as to what I can look at to figure out what is happening with the data I am posting. I was watching the metrics collector log while posting and querying and didn't see any activity besides the periodic aggregation. Any suggestions would be greatly appreciated. Thanks, Bran
