Sam Tunnicliffe commented on CASSANDRA-11967: --------------------------------------------- +1 the C* changes look fine to me. I should note though that when I dropped in the necessary jars to smoke test with the Prometheus exporter, I'm seeing an awful lot of {noformat} INFO [main] 2016-06-24 16:56:27,809 CassandraDaemon.java:375 - Trying to initialize metrics-exporter org.caffinitas.prometheusmetrics.PrometheusMetricsInitializer INFO [main] 2016-06-24 16:56:27,825 PrometheusMetricsExporter.java:82 - Setting up Prometheus metrics exporter on 127.0.0.1 port 8088 and SSL disabled INFO [main] 2016-06-24 16:56:27,829 PrometheusMetricsExporter.java:450 - No matching metric mapping for 'org.apache.cassandra.metrics.Table.BloomFilterFalsePositives.system.built_views' INFO [main] 2016-06-24 16:56:27,830 PrometheusMetricsExporter.java:450 - No matching metric mapping for 'org.apache.cassandra.metrics.Table.BytesFlushed.system.peers' INFO [main] 2016-06-24 16:56:27,830 PrometheusMetricsExporter.java:450 - No matching metric mapping for 'org.apache.cassandra.metrics.Table.RowCacheHit.system.available_ranges' INFO [main] 2016-06-24 16:56:27,830 PrometheusMetricsExporter.java:450 - No matching metric mapping for 'org.apache.cassandra.metrics.Table.MeanPartitionSize.system.views_builds_in_progress' INFO [main] 2016-06-24 16:56:27,831 PrometheusMetricsExporter.java:450 - No matching metric mapping for 'org.apache.cassandra.metrics.Table.CoordinatorReadLatency.system.local' INFO [main] 2016-06-24 16:56:27,831 PrometheusMetricsExporter.java:450 - No matching metric mapping for 'org.apache.cassandra.metrics.Table.EstimatedPartitionSizeHistogram.system.batches' INFO [main] 2016-06-24 16:56:27,831 PrometheusMetricsExporter.java:450 - No matching metric mapping for 'org.apache.cassandra.metrics.Table.MemtableOffHeapSize.system.views_builds_in_progress' INFO [main] 2016-06-24 16:56:27,831 PrometheusMetricsExporter.java:450 - No matching metric mapping for 'org.apache.cassandra.metrics.Table.SSTablesPerReadHistogram.system_traces.sessions' INFO [main] 2016-06-24 16:56:27,831 PrometheusMetricsExporter.java:450 - No matching metric mapping for 'org.apache.cassandra.metrics.keyspace.LiveScannedHistogram.system' INFO [main] 2016-06-24 16:56:27,831 PrometheusMetricsExporter.java:450 - No matching metric mapping for 'org.apache.cassandra.metrics.Table.CasPrepareLatency.system.schema_aggregates' {noformat} > Export metrics for prometheus in its native format > -------------------------------------------------- > > Key: CASSANDRA-11967 > URL: https://issues.apache.org/jira/browse/CASSANDRA-11967 > Project: Cassandra > Issue Type: Improvement > Reporter: Robert Stupp > Assignee: Robert Stupp > Priority: Minor > Fix For: 3.x > > > https://github.com/snazy/prometheus-metrics-exporter allows to export > codahale metrics for prometheus.io. In order to integrate this, a minor > change to C* is necessary to load the library. > This eliminates the need to use the additional graphite-exporter tool and > therefore also allows prometheus to track the up/down status of C*. > (Will provide the patch soon) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
