Logback => TLS/SSL => Syslog ?
by Otis Gospodnetić 21 Feb '19

Hi, Does Logback support sending logs to Syslog servers via TLS/SSL? I have a feeling Logback doesn't have a SyslogAppender that can send data using TLS. I say that because I don't see a mention of "syslog" on http://logback.qos.ch/manual/usingSSL.html and I see http://jira.qos.ch/browse/LOGBACK-890 that mentions TLSSyslogAppender, but it looks like this never ended up in Logback. I've only found it committed here: https://github.com/balabit/logback/commit/e0d89de2536e0925a6c816a50793f6a74… Could anyone please clarify? Thanks, Otis -- Monitoring * Alerting * Anomaly Detection * Centralized Log Management Solr & Elasticsearch Support * http://sematext.com/

LOGBACK-1189: detect previous copyAttributeMap calls
by Mark Elliot 07 Dec '16

Hi, there's a serious functionality bug with logback-access described in LOGBACK-1189 (which also proposes a fix). I pushed a fix here https://github.com/qos-ch/logback/pull/336 <https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_qos-2Dch_lo…>, and wonder when we might be able to get this merged and released. I suspect http://mailman.qos.ch/pipermail/logback-user/2016-September/004800.html is another (and high profile) manifestation of this problem. Thanks, Mark

Is there a way to define a variable by making a call to Joran?
by Benson Margulies 04 Nov '16

I looked quickly through the class stack for the Joran configurator, but I didn't spot anything. Is there something I'm missing? I want to have an XML file with some variable references, configure explicitly with Joran, and set some vars. I can write code to edit the XML or to set system props, but I was hoping for something cleaner.

Log forging prevention
by Svetlin Zarev 04 Nov '16

Hello, What's the recommended way to protect against log forging attacks with logback (using pattern layout) ? Is there a way to specify a set of reserved characters and tell logback to escape them ? Kind regards, Svetlin

I do not have INFO messages enabled for ch.qos, is there something else I need to do to avoid this noise from <contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator"/> ? 09:54:34,959 |-INFO in ch.qos.logback.classic.joran.action.LoggerAction - Setting level of logger [com.basistech.ws.worker.core.ComponentServiceTrackerImpl] to INFO 09:54:34,959 |-INFO in ch.qos.logback.classic.jul.LevelChangePropagator@7d70d1b1 - Propagating INFO level on Logger[com.basistech.ws.worker.core.ComponentServiceTrackerImpl] onto the JUL framework 09:54:34,959 |-INFO in ch.qos.logback.classic.joran.action.LoggerAction - Setting level of logger [org.apache] to WARN 09:54:34,959 |-INFO in ch.qos.logback.classic.jul.LevelChangePropagator@7d70d1b1 - Propagating WARN level on Logger[org.apache] onto the JUL framework 09:54:34,959 |-INFO in ch.qos.logback.classic.joran.action.LoggerAction - Setting level of logger [org.apache.felix] to INFO
