Problems with Metric Collector host
- Output of "rpm -qa | grep ambari" on the collector host.
- Total available System memory, output of : "free -g"
- Total available disk space and available partitions, output of : "df -h "
- Total number of hosts in the cluster
- Services deployed in the cluster (This is purely to estimate the amount of metric data generated)
- Collector configs: /etc/ams-hbase/conf/hbase-env.sh, /etc/ams-hbase/conf/hbase-site.xml, /etc/ambari-metrics-collector/conf/ams-env.sh, /etc/ambari-metrics-collector/conf/ams-site.xml
- Collector logs: /var/log/ambari-metrics-collector/ambari-metrics-collector.log, /var/log/ambari-metrics-collector/hbase-ams-master-<host>.log, /var/log/ambari-metrics-collector/hbase-ams-master-<host>.out
Note: Additionally, If distributed mode is enabled, /var/log/ambari-metrics-collector/hbase-ams-zookeeper-<host>.log, /var/log/ambari-metrics-collector/hbase-ams-regionserver-<host>.log - Response to the following URLs -
http://<ams-host>:6188/ws/v1/timeline/metrics/metadata

The response will be JSON and can be attached as a file. - From AMS HBase Master UI - http://<METRICS_COLLECTOR_HOST>:61310
