What is the recommended integration with twisted clocks / funnels?

Question

There are many integrations for ravens, including python logging. On the one hand, twisted does not use python protocols. And on the other hand, there is no direct integration for a raven in a twisted form.

So what is the best practice of using raven in twisted-tune settings?

Answer 1

raven captureException can be captureException only without arguments, if there is an active event, which does not always happen when a log observer is called. So, instead, pull the exception information from Failure that is logged:

 from twisted.python import log from raven import Client client = Client(dsn='twisted+http://YOUR_DSN_HERE') def logToSentry(event): if not event.get('isError') or 'failure' not in event: return f = event['failure'] client.captureException((f.type, f.value, f.getTracebackObject())) log.addObserver(logToSentry) 

Answer 2

user1252307 The answer is a great start, but on the watchdog side you get a relatively useless dictionary and stack trace.

If you are trying to view and track unexpected exceptions, try this small change in the log_sentry function:

 from twisted.python import log from raven import Client client = Client(dsn='twisted+http://YOUR_DSN_HERE') def log_sentry(dictionary): if dictionary.get('isError'): if 'failure' in dictionary: client.captureException() # Send the current exception info to Sentry. else: #format the dictionary in whatever way you want client.captureMessage(dictionary) log.addObserver(log_sentry) 

There may be a better way to filter the exception-based error message, and this may try to emit exception information that does not exist where there are errors that are not exceptions.

 from twisted.python import log from raven import Client client = Client(dsn='twisted+http://YOUR_DSN_HERE') def log_sentry(dictionary): if dictionary.get('isError'): #format the dictionary in whatever way you want client.captureMessage(dictionary) log.addObserver(log_sentry)
