Re: Event / Exchange / Message timestamps

[ski n]

I also need the payload size of a message (in bytes) for each event and
totals if possible

Messages are mostly String, but can be any object basically (list, zip,
mail, pdf, image). Is this possible? Or is there another way to get this
kind of metric?
The alternative is to offload it to, for example Elastic, but there maybe
easier ways to get size stats.

Yes, I was suspecting something like that, but the Javadoc only says:

"Timestamp for each event, when the event occurred. By default, the
timestamp is not included and this method returns 0."

It does not say how and where it can be turned on. I first checked the
EventNotifierSupport class, but apparently it needs to be set on the
EventFactory:

https://www.javadoc.io/static/org.apache.camel/camel-api/3.20.8/org/apache/camel/spi/EventFactory.html#setTimestampEnabled(boolean)

Something like:

context.getManagementStrategy().getEventFactory().setTimestampEnabled(true);

Hope this will help someone.

Hi

No see the javadoc

You need to turn on event timestamps

Event / Exchange / Message timestamps

[ski n]

In Camel 3.20.8 I use the event notifier (as described here
https://dzone.com/articles/event-notifier-apache-camel).

One of the things I try to get timestamps. These timestamps are available
on several levels:

1. Event level
2. Exchange level
3. Message level

When I used the following the get the timestamps:

CamelEvent.ExchangeEvent exchangeEvent = (CamelEvent.ExchangeEvent) event;

// Get the message exchange from exchange event
Exchange exchange = exchangeEvent.getExchange();

System.out.println("Timestamp 1 " + event.getTimestamp());
System.out.println("Timestamp 2 " + exchangeEvent.getTimestamp());
System.out.println("Timestamp 3 " + exchange.getCreated());
System.out.println("Timestamp 4 " + exchange.getIn().getMessageTimestamp());


Only timestamp 3 (exchange.getCreated()) gives a timestamp, but the others
are 0. For message timestamps this can be correct (as that depends on
ActiveMQ etc), but shouldn't the event always a timestamp?
