2017-05-08 | logger: Added logger_queue_limit to the configuration options. | George Joseph | |
All log messages go to a queue serviced by a single thread which does all the IO. This setting controls how big that queue can get (and therefore how much memory is allocated) before new messages are discarded. The default is 1000. Should something go bezerk and log tons of messages in a tight loop, this will prevent memory escalation. When the limit is reached, a WARNING is logged to that effect and messages are discarded until the queue is empty again. At that time another WARNING will be logged with the count of discarded messages. There's no "low water mark" for this queue because the logger thread empties the entire queue and processes it in 1 batch before going back and waiting on the queue again. Implementing a low water mark would mean additional locking as the thread processes each message and it's not worth it. A "test" was added to test_logger.c but since the outcome is non-deterministic, it's really just a cli command, not a unit test. Change-Id: Ib4520c95e1ca5325dbf584c7989ce391649836d1 | |||
2015-09-29 | main/logger: Add log formatters and JSON structured logs | Matt Jordan | |
When Asterisk is part of a larger distributed system, log files are often gathered using tools (such as logstash) that prefer to consume information and have it rendered using other tools (such as Kibana) that prefer a structured format, e.g., JSON. This patch adds support for JSON formatted logs by adding support for an optional log format specifier in Asterisk's logging subsystem. By adding a format specifier of '[json]': full => [json]debug,verbose,notice,warning,error Log messages will be output to the 'full' channel in the following format: { "hostname": Hostname or name specified in asterisk.conf "timestamp": Date/Time "identifiers": { "lwp": Thread ID, "callid": Call Identifier } "logmsg": { "location": { "filename": Name of the file that generated the log statement "function": Function that generated the log statement "line": Line number that called the logging function } "level": Log level, e.g., DEBUG, VERBOSE, etc. "message": Actual text of the log message } } ASTERISK-25425 #close Change-Id: I8649bfedf3fb7bf3138008cc11565553209cc238 | |||
2014-07-17 | configs: Move sample config files into a subdirectory of configs | Matthew Jordan | |
This moves all samples configs from configs/ to configs/samples. This allows for additional sets of sample configuration files to be added in the future.
