Write to Event Logs

In C# code you can get the IEventLog API and then call Write, for example:

var log = Apis.Get<IEventLog>();

var options = new EventLogEntryWriteOptions {
    Category = "Your Category Name",
    EventId = 1,    // Your Event Id
    EventType = "Information"; // Or "Warning" or "Error"
};

log.Write("Your Message", options);

In Velocity code:

#set($category = "Your Category")
#set($eventId = 1) ## Your Event Id
#set($eventType = "Information") ## Or "Warning" or "Error"

$core_v2_eventLog.Write("Your Message", "%{Category = $category, EventId = $eventId, EventType = $eventType}")

Hope this helps!
