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 extensions missing debug info

Please include debugging info when compiling source code (in particular, Logback Spring extension), so that stepping through logback source code is possible when debugging.

Re: [logback-user] Truncation of log entry when using a specific sequence of '}]:' characters
by Jeffrey Olchovy 28 Oct '15

This was an issue with me not adhering to the (obsolete) syslog protocol (https://www.ietf.org/rfc/rfc3164.txt, section 4.1.3). Our TAG part of the message was greater than 32 characters and was being truncated. In the example, I used a false string ‘foo-service’. In reality, it was much longer (service-xxxxxxxxxxx). That, combined with the 12 character hex ‘pid’ and decorating brackets, pushed us over the limit. It rendered correctly with the spaces surrounding the hex characters since the whitespace violated the pattern that would attempt to identity (and subsequently, truncate) the TAG. There is no issue with logback’s layouts or the SyslogAppender. However, we would like to benefit from the outstanding issue and associated patch with regard to additional configuration of the SyslogAppender and SyslogStartConverter : http://jira.qos.ch/browse/LOGBACK-1011, https://github.com/qos-ch/logback/pull/139. These are quite old and I am curious if they are part of any planned releases. Thanks.

PPG encrypted appender
by Rob GB 27 Oct '15

27 Oct '15

Hi LB people, I wonder what would be the way to create an encrypted file appender. Not sure if it is best to create a complete new appender or encoder. My strategy is to write encrypted lines, one by one, then logback rotates the file. Thanks.

Truncation of log entry when using a specific sequence of '}]:' characters
by Jeffrey Olchovy 27 Oct '15

27 Oct '15

Hello, I am experiencing an unexpected truncation of part of my log entry when using the SyslogAppender with the following suffixPattern: <suffixPattern>foo-service[${HOSTNAME}]: %logger %msg</suffixPattern> The resulting output takes the form: foo-service[f7e52cff05ba com.tapad.common.cache.SelfRefreshingCache Cache Constraints lookup refreshing… foo-service[f7e52cff05ba com.tapad.common.cache.SelfRefreshingCache Cache Constraints lookup refreshed and now contains 284 items. Rather than the expected: foo-service[f7e52cff05ba]: com.tapad.common.cache.SelfRefreshingCache Cache Constraints lookup refreshing… foo-service[f7e52cff05ba]: com.tapad.common.cache.SelfRefreshingCache Cache Constraints lookup refreshed and now contains 284 items. If I add spaces between the intended variable ${HOSTNAME} and the square brackets, the log entries render as one would expect: foo-service[ 28ed24577053 ]: com.tapad.common.cache.SelfRefreshingCache Cache Constraints lookup refreshing… foo-service[ 28ed24577053 ]: com.tapad.common.cache.SelfRefreshingCache Cache Constraints lookup refreshed and now contains 284 items. Are there any known issues or workarounds that either will prevent or resolve this behavior? Or, alternatively, does this smell like something downstream of logback and more at the syslog level? Thank you.

logback.xml and logback-test.xml
by Trupti Mali 07 Oct '15

07 Oct '15

Hi, This is my very first post to this mailing list. I need one help from logback users. I wanted to setup logback with two sets of config files. 1) for production and 2) for test hence referring to the instrucitons posted on logback website - I added logback-test.xml and logback.xml to my config file. I was expecting logback-test.xml to be picked up first over logback.xml . But at runtime only logback.xml is getting picked. Can these two files coexist and can we still manage to get one of them picked during runtime and how? Help much appreciated. Thanks Trupti
