[JIRA] (LOGBACK-1513) Add possibity for separate logging for JPMS module/layers
by QOS.CH (JIRA) 29 Mar '20

Pavel_K created LOGBACK-1513: -------------------------------- Summary: Add possibity for separate logging for JPMS module/layers Key: LOGBACK-1513 URL: https://jira.qos.ch/browse/LOGBACK-1513 Project: logback Issue Type: New Feature Environment: I suggest to add possibility for separate logging for JPMS module/layers. For example, it would be possible to route messages from different modules/layers to separate log files.

[JIRA] (LOGBACK-1512) let SCHEDULED_EXECUTOR_POOL_SIZE be configurable
by QOS.CH (JIRA) 26 Mar '20

Liang Xie created LOGBACK-1512: ---------------------------------- Summary: let SCHEDULED_EXECUTOR_POOL_SIZE be configurable Key: LOGBACK-1512 URL: https://jira.qos.ch/browse/LOGBACK-1512 Project: logback Issue Type: Improvement Components: logback-classic, logback-core Affects Versions: 1.3.0-alpha5, 1.2.3, 1.1.11 Environment: AWS m5.xlarge ec2 instance, vCPU num: 4 Reporter: Liang Xie Assignee: Logback dev list Attachments: cpu_spike.png, latency.png Our log servers deployed logback component, the logback configuration contains tens of appenders, this is one of the appender definition: {quote}<appender name="rawdata" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>/data/xxx/rawdata/rawdata.log</file> <encoder> <pattern>%m%n</pattern> </encoder> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>/data/xxx/rawdata/rawdata.log.%d\{yyyy-MM-dd-HH}.gz</fileNamePattern> </rollingPolicy> </appender> {quote} please note the "fileNamePattern" value, we use gzip compression, it means in each hour beginning, all the tens of files are renamed to tmp files, then be compressed in the thread pool. Currently, this thread pool core size is immutable, a fixed value: 8, which came from [https://github.com/qos-ch/logback/commit/b946551439134] In an small ec2 env with tens of big log files(a few of our rolling raw log files size are 10 Gb), say 4 vcore, the compression will be last several minutes with all vcores running in full speed. It will disturb the normal user request latency espencially under a high throughput env. Our proposed solution are as following: 1. let SCHEDULED_EXECUTOR_POOL_SIZE be configurable, it is meaningful since the logback users have different cpu core configs, different requirements(latency vs throughput) 2. let the compression level be configurable, currently, the logback uses JDK's GZIPOutputStream class, which deflate algorithm is DEFAULT_COMPRESSION always. It would be great if we could make it be configurable. We forked a branch, after updating SCHEDULED_EXECUTOR_POOL_SIZE to 1 and deflate algorithm to BEST_SPEED, we have observed the each hour beginning's cpu spikes were relieved , and the user request latency is more stable than before Any comments are welcome -- This message was sent by Atlassian JIRA (v7.3.1#73012)

Expired SSL certificates
by Mark Carroll 23 Mar '20

23 Mar '20

I'm guessing it is known that the webserver TLS certificates for https://logback.qos.ch/ and https://www.slf4j.org/ expired last week? Apologies if I missed the mailing list traffic or bug report for it or if this is the wrong place to mention the issue. -- Mark The University of Dundee is a registered Scottish Charity, No: SC015096
