migration instructions when coming from ES exporter

Open rursprung opened this issue 3 years ago • 3 comments

is there a list of things (relevant for consumers) which changed between the original ES plugin (on 7.10.2) and this one? i can see that starting with #10 the default prefix is now opensearch_ and not es_ anymore (but can be configured). it might be good if a small migration guide (ES 7.10.2 -> OpenSearch 1.x -> OpenSearch 2.x) could be added to the README. thanks!

Good idea. Right now the migration should be simple (except the prefix as you pointed out).

For opensearch 2.1.0 version, apart from prefix I see many metrics not showing up in-comparison to ES exporter.

Ex: all health related metrics.

elasticsearch_cluster_health_active_primary_shards

Hi @ervikrant06

Is it the same metric that is pulled from ClusterHealth response? See: https://github.com/aiven/prometheus-exporter-plugin-for-opensearch/blob/8f24ffbf3fc0965027b360ff3cd6eb71d53c9a45/src/main/java/org/compuscene/metrics/prometheus/PrometheusMetricsCollector.java#L114
