[FEATURE]Alerting backend roles not working even after enabling the backend roles

[Sreekanth-hubs]

Is your feature request related to a problem?
Describe the issue: We are trying to create the alert monitors in different tenants but however all the monitors are being visible in both the tenants and app teams are complaining about the RBAC in the alerting plugin.

Even after enabling the backend roles the rbac with alerting plugin is not working. Below is the settings that are enabled in the cluster.
settings_in_cluster:

{ “persistent”: { “cluster”: { “routing”: { “allocation”: { “cluster_concurrent_rebalance”: “50”, “node_concurrent_recoveries”: “50”, “enable”: “all”, “total_shards_per_node”: “5000” } }, “max_shards_per_node”: “5000” }, “indices”: { “breaker”: { “fielddata”: { “limit”: “60%” } }, “recovery”: { “max_bytes_per_sec”: “1024mb”, “max_concurrent_file_chunks”: “5”, “max_concurrent_operations”: “4” } }, “opensearch”: { “notifications”: { “general”: { “filter_by_backend_roles”: “true” } } }, “plugins”: { “index_state_management”: { “metadata_migration”: { “status”: “1” }, “template_migration”: { “control”: “-1” } }, “alerting”: { “filter_by_backend_roles”: “true” } } }, “transient”: { “cluster”: { “routing”: { “allocation”: { “disk”: { “watermark”: { “low”: “95%”, “flood_stage”: “95%”, “high”: “95%” } }, “enable”: “all”, “total_shards_per_node”: “5000” } }, “info”: { “update”: { “interval”: “1m” } }, “max_shards_per_node”: “5000” }, “plugins”: { “anomaly_detection”: { “filter_by_backend_roles”: “true” }, “alerting”: { “filter_by_backend_roles”: “true” } } } }
Roles&users:
Below are the configuration I have used for the tenants , Roles, Internal users.
For the internal users We have provided the pre-defined roles as alerting_full_access

What solution would you like?
I want to create monitors inside different tenants and one tenant user should not view another tenant alert monitors

What alternatives have you considered?
Even after creating via API's monitor got triggered but under the global tenant, not under specified tenant.

curl -k -u admin:admin -XPOST "https://127.0.0.1:9200/_plugins/_alerting/monitors" -H "Content-Type: application/json" -H "securitytenant: Tenant-1" -d '{

Closing in favor of the issue that I cloned to alerting repo to which this issue is relevant.

Sure @eirsep Thanks for the confirmation on this that alerting plugin does not support multi tenancy.
