Describe the issue:

Hello everyone, when I request metrics, I get a response, but it’s as if there are no values.

Configuration:

metrics-location = /dev/shm/performanceanalyzer/
metrics-deletion-interval = 1
cleanup-metrics-db-files = true
webservice-listener-port = 9600
rpc-port = 9650
metrics-db-file-prefix-path = /tmp/metricsdb_
https-enabled = true

certificate-file-path = /opt/opensearch/config/certs/edu-osm-21.pem
private-key-file-path = /opt/opensearch/config/certs/edu-osm-21-key.pem
trusted-cas-file-path = /opt/opensearch/config/certs/root-ca.pem

client-certificate-file-path = /opt/opensearch/config/certs/admin.pem
client-private-key-file-path = /opt/opensearch/config/certs/admin-key.pem
