Key substitution string for ServerName when publishing Domino statistics to external services

I want to use the use new feature "Publishing Domino statistics to external services".

And in documentation there is no key substitution string for Domino $ServerName$, see below:

https://help.hcltechsw.com/domino/10.0.1/stats_publish_other_external.html

I have multiple server (more than 100 servers), so must change the configuration for each server because there is no key substitution string for ServerName.

If exists i can use a Configuration Document, to configure all servers.

Example of my settings:

set config STATPUB_ENABLE=1

set config STATPUB_URI=http://elasticsearch.renovations.com:9200/

set config STATPUB_METRIC_FORMAT=""$Name$":$Value$

set config STATPUB_DELTA_METRIC_FORMAT=""$Name$":$Value$

set config STATPUB_HEADERS=X-License-Key: XXXXXX$Newline$Content-Type: application/json$Newline$Accept: application/json$Newline$

set config STATPUB_DATA_HEAD={"host":"myserver","version":"1.0.0","name":"myserver/Renovations","timestamp":"$Timestamp$","guid":"com.renovations.domstats","duration":60,"metrics":{

set config STATPUB_DATA_TAIL=}}

Domino will post the following data on Elasticsearch

{

"host": "myserver",

"version": "1.0.0",

"name": "myserver/Renovations",

"timestamp": "1581518363",

"guid": "com.renovations.domstats",

"duration": 60,

"metrics": {

"ADMINP.DirectoryDocumentsModified": 1,

"ADMINP.RelativeResponsesAdded": 6,

"ADMINP.ReplicasCreated": 4,

.....

}

}
