In case you were impacted by the back-and-forth of Elasticsearch's change of license and have somewhere now implemented OpenSearch as an Elasticsearch alternative and you were looking for a monitoring plugin, you're in luck.

Because OpenSearch is a fork of the back then open sourced (and meanwhile open source again) Elasticsearch, there are similarities between the two. Mainly the status API is very helpful to have a quick glance over the cluster or node status. 

For this purpose you can use the check_es_system monitoring plugin 1:1 as if you'd monitor an Elasticsearch cluster or node:

ck@opensearch:~$ /usr/lib/nagios/plugins/check_es_system.sh -H localhost -t status
ES SYSTEM OK - Elasticsearch Cluster "opensearch" is green (1 nodes, 1 data nodes, 3 shards, 453 docs)|total_nodes=1;;;; data_nodes=1;;;; total_shards=3;;;; relocating_shards=0;;;; initializing_shards=0;;;; unassigned_shards=0;;;; docs=453;;;;

So far all the check types of the plugin have been successfully tested on an OpenSearch 2.12 instance. The documentation was appended with a Elasticsearch + Opensearch compatibility matrix.
