Wildfly raven sentry logging

[jim]

Hi,

I want to log the errors to sentry server from a wildfly application. I am using java.util.logging in my project.

I tried adding a custom-handler as mentioned in here. Added raven jar as a global module to wildfly subsystem. But still nothing is logged to sentry. Unfortunately, I am not getting any exceptions to indicate something is wrong. Logs are shown in console and server.log but not in sentry.

I could not find proper configuration notes on this topic. Please help me.

Thanks in advance.

I’m not super familiar with Java, but just to confirm have you followed the instructions here:

Hi David,

Thanks a lot for the response. Yes, I have tried these but no luck. Wildfly logging is bit different I guess. Need to figure it out.

Definitely keep us posted. It's hard to keep up with all the integrations but I'm sure others will find it useful

Hi David,

I could not find a proper solution for this. I use java.util.logging in the wildfly application.

1. Added the maven dependency to the project

2. Added logging.properties in the jboss logging.properties format. At first, I tried with the logging.properties entries exactly as given in here but wildfly failed to read that config. Then I tried the below one.

---

logger.level=WARN

logger.handlers=SENTRY

handler.SENTRY=net.kencochrane.raven.jul.SentryHandler

handler.SENTRY.properties=net.kencochrane.raven.jul.SentryHandler.dsn, net.kencochrane.raven.jul.SentryHandler.tags

handler.SENTRY.net.kencochrane.raven.jul.SentryHandler.dsn=https://publicKey:secretKey@host:port/1?options

handler.SENTRY.net.kencochrane.raven.jul.SentryHandler.tags=tag1:value1,tag2:value2

---

3. Added raven jar as a wildfly module.

Now, I get the below error when application is deployed

---

    Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS011555: Failed to configure logging using 'logging.properties' configuration file.

    Caused by: java.lang.IllegalArgumentException: No property \"net.kencochrane.raven.jul.SentryHandler.dsn\" setter found for handler \"SENTRY\""}}

---

I could see that there is no associated setter method for net.kencochrane.raven.jul.SentryHandler.dsn in the SentryHandler class. I tried adding a setter method for this which I could locate in raven-logback project. Then the error disappeared and I could see that dsn variable in SentryHandler class is a null value when wildfly starts up. This means dsn value is never properly read by LogManager. Please help me to find a solution. 

Thanks in advance.

Is it possible its not finding the library? I haven’t really used Java in a long time (and never used the logging libraries) so I’m not the best person to provide advice here.

You may also consider opening a ticket about the lack of setter. That could indicate a problem with the code or simply that it’s not reading it correctly.
