Best way to capture logs from worker processes?

1

Hi there,

We have a couple of worker processes running (RabbitMQ consumers). How might we get a log drain from them?

Thanks!

Hi there,

There are two ways to do this:

  • You can use the Aptible CLI, with aptible logs --app $APP_HANDLE. This will stream the logs from your app in real-time to your terminal.
  • You can create a new Log Drain from the “Logging” tab in the Dashboard. You’ll have to send those logs somewhere, of course. The two main options are using a supported logging provider (anything that can accept logs via syslog over tls should work, so that includes e.g. Papertrail and Logentries), or set up an Elasticsearch + Kibana on Aptible to access your logs.

There’s more information here if you’d like.

Let me know if you have any questions!

Hey Thomas,

Thanks for the response! So both of these options will just combine all logging output from any service in the app (ie, the web service and a couple of other distinct worker services running in different containers)?

Yes, that’s correct: all logging output will be captured. In all cases, there is metadata on the log records showing which service they’re coming from, though:

  • Using the Aptible CLI or a Syslog Log Drain, the service is shown as a prefix.
  • Using an Elasticsearch or HTTPS Log Drain, the service is provided as a service attribute on log records (the log record itself is found in the log attribute).

Cheers,
