GC logs
By default garbage collector log files are located in /usr/local/FlashphonerWebCallServer/logs directory.
| Code Block | ||
|---|---|---|

logs
---- gc-core-2018-12-18_20-02.log
---- gc-core-2018-12-18_19-56.log |
The location and prefix of the log files can be configured in wcs-core.properties file.
To enable log rotation by the JVM, the following options can be added to wcs-core.properties:
| Code Block | ||
|---|---|---|
| ||
-XX:+UseGCLogFileRotation
-XX:NumberOfGCLogFiles=10
-XX:GCLogFileSize=2M |
Then the log files will have names like
| Code Block | ||
|---|---|---|

logs
---- gc-core.log2018-12-14_18-57.log.0
---- gc-core.log2018-12-14_18-57.log.1
---- gc-core.log2018-12-14_18-57.log.2
---- gc-core.log2018-12-14_18-57.log.3
---- gc-core.log2018-12-14_18-57.log.4.current |
File with suffix 'current' is the file currently being recorded.
To remove creation time from log file names, remove date from variable GC_SUFFIX in bin/setenv.sh:
| Code Block | ||
|---|---|---|
| ||
GC_SUFFIX=".log" |
Then the log files will have names like
