I've not used splunk but the idea of central logging is a good one. It does look easy enough to send data to splunk once the server is set up. This is not tested, but something close to this should do the trick:
New HTTP Request(
URL( "https://your-hostname:8088/services/collector" ),
Method( "POST" ),
Headers([
"Accept" => "application/json",
"Authorization" => "Splunk your-hec-token"
]),
JSON([
"event" => "Test message",
"sourcetype" => "jmp/jsl"
])
) << Send;
