How can I add metadata to events at the forwarder?

I'd like to add metadata to my events at the source and change the _meta value periodically without restarting the forwarders.

forwarder:
inputs.conf
[monitor::///var/logs]
_meta = foo:bar

foo represents field name , bar represents field value

indexers:
fields.conf
[foo]
INDEXED = true

I also want to update the metadata value periodically without restarting Splunk on the forwarders.

$SPLUNK_HOME/bin
./splunk _internal call /services/data/inputs/monitor/_reload -auth admin:changeme

No. The only "variable" (runtime-determined) parts of the config are those explicitly defined as such in specs.

For example - serverName parameter in [general] section of server.conf. The specs say that it can contain environment variables so it can be dynamically set. For other parameters you define constant values.

@michaelissartel I haven't tested using an env variable as the field value before. If you do end up testing can you put your reply here for others?

In case anyone else runs across this, the proper syntax in the inputs.conf is
_meta = foo::bar
two colons between the key and value instead of one.
