11/13/2023 0 Comments Elastic search exporter(And we don’t have acces to Prometheus with machines Opensearch) => I don’t know how to use dynamic discovery node and i not view documentation about that. Prometheus is not direcly accessible by physical machine, we have to pass through a push gateway. ![]() (we must use Push Gateway to export Metrics to Prometheus). (java process)ħ2 nodes (4 on each machine) : 3 masters, 6 coordinators (4 for dedicated writting) and 63 data nodes. (…more consumer)Ĭan you please share more details about your OpenSearch cluster - Prometheus setup? How is Prometheus discovering individual OpenSearch nodes? Do you provide static list of nodes to scrape or do you rely on dynamic node discovery?ġ8 Linux physical machine with 300 GB RAM. So 4 320 000 metrics scraped at each scrapping.įor cluster informations it’s the same behavior.įor nodes stats, you must deploy plugin on all nodes to have full metrics like elasticsearch exporter. Plugin Opensearch exporter generated by default, 60 000 metrics by nodes. Options to limits metrics like indices, settings must be write in opensearch.yml ? Dynamic updated settings go to 404 error from GitHub - aparo/opensearch-prometheus-exporter: OpenSearch Prometheus Exporter (fork of )īUT if plugin is not deploy on all nodes, only metrics about the node where exporter was installed are scraped. ![]() ![]() I cannot configure the listening port (is not a problem because i can use push gateway…). Was installed like a plugin on Opensearch. Volume of metrics (with full options) : 60 000 * 2 elasticsearch exporter (like 2 for HA) Ok it is a spof, but I just have to install it on another machine to have HA. With just one install of this exporter, i have all metrics of cluster and nodes ! (If i install elasticsearch exporter on another node, we will have 22 000 * 2 metrics scraped.)įor information, we all options set, elasticsearch exporter generate 60 000 metrics by default. With es.all this exporter generated 22 000 metrics AND i have all metrics for all nodes ! I use es.all option to retrieve all cluster and node stats. Was installed like a java process on one physcal machine Opensearch. The OpenSearch exporter works the same way as the original Elasticsearch exporter. Even for Elasticsearch exporter the recommendation was to install it on all nodes (because generally the assumption is that Prometheus is scraping metrics from all cluster nodes thus the plugin must be present on every node). I would be really interested in learning more details. ![]() If i want monitoring cluster, i need to deploy this plugin on all nodes ? > Installed prometheus-exporter with folder name prometheus-exporter * suppressAccessChecksįor descriptions of what these permissions allow and the associated risks. * Classname: .PrometheusExporterPluginįolder WARNING: plugin requires additional permissions Retrieving zip from file:///home/osadmin/prometheus-exporter-1.2.3.zipĭescription: Export OpenSearch metrics to Prometheus > Downloading file:///home/osadmin/prometheus-exporter-1.2.3.zip So, it seems good now : -> Installing file:///home/osadmin/prometheus-exporter-1.2.3.zip
