LOG_LEVEL_SYSLOG - ZoneMinder logging is now more integrated between components and allows you to specify the destination for logging output and the individual levels for each. This option lets you control the level of logging output that goes to the system log. ZoneMinder binaries have always logged to the system log but now scripts and web logging is also included. To preserve the previous behaviour you should ensure this value is set to Info or Warning. This option controls the maximum level of logging that will be written, so Info includes Warnings and Errors etc. To disable entirely, set this option to None. You should use caution when setting this option to Debug as it can affect severely affect system performance. If you want debug you will also need to set a level and component below

LOG_LEVEL_FILE - ZoneMinder logging is now more integrated between components and allows you to specify the destination for logging output and the individual levels for each. This option lets you control the level of logging output that goes to individual log files written by specific components. This is how logging worked previously and although useful for tracking down issues in specific components it also resulted in many disparate log files. To preserve this behaviour you should ensure this value is set to Info or Warning. This option controls the maximum level of logging that will be written, so Info includes Warnings and Errors etc. To disable entirely, set this option to None.

LOG_LEVEL_WEBLOG - ZoneMinder logging is now more integrated between components and allows you to specify the destination for logging output and the individual levels for each. This option lets you control the level of logging output from the web interface that goes to the httpd error log. Note that only web logging from PHP and JavaScript files is included and so this option is really only useful for investigating specific issues with those components. This option controls the maximum level of logging that will be written, so Info includes Warnings and Errors etc. To disable entirely, set this option to None.

LOG_LEVEL_DATABASE - ZoneMinder logging is now more integrated between components and allows you to specify the destination for logging output and the individual levels for each. This option lets you control the level of logging output that is written to the database. This is a new option which can make viewing logging output easier and more intuitive and also makes it easier to get an overall impression of how the system is performing. If you have a large or very busy system then it is possible that use of this option may slow your system down if the table becomes very large. Ensure you use the LOG_DATABASE_LIMIT option to keep the table to a manageable size.

LOG_DATABASE_LIMIT - If you are using database logging then it is possible to quickly build up a large number of entries in the Logs table. This option allows you to specify how many of these entries are kept. If you set this option to a number greater than zero then that number is used to determine the maximum number of rows, less than or equal to zero indicates no limit and is not recommended. You can also set this value to time values such as '<n> day' which will limit the log entries to those newer than that time. You can specify 'hour', 'day', 'week', 'month' and 'year', note that the values should be singular (no 's' at the end). The Logs table is pruned periodically so it is possible for more than the expected number of rows to be present briefly in the meantime.

RECORD_DIAG_IMAGES - In addition to recording event statistics you can also record the intermediate diagnostic images that display the results of the various checks and processing that occur when trying to determine if an alarm event has taken place. There are several of these images generated for each frame and zone for each alarm or alert frame so this can have a massive impact on performance. Only switch this setting on for debug or analysis purposes and remember to switch it off again once no longer required.
DUMP_CORES - When an unrecoverable error occurs in a ZoneMinder binary process is has traditionally been trapped and the details written to logs to aid in remote analysis. However in some cases it is easier to diagnose the error if a core file, which is a memory dump of the process at the time of the error, is created. This can be interactively analysed in the debugger and may reveal more or better information than that available from the logs. This option is recommended for advanced users only otherwise leave at the default. Note using this option to trigger core files will mean that there will be no indication in the binary logs that a process has died, they will just stop, however the zmdc log will still contain an entry. Also note that you may have to explicitly enable core file creation on your system via the 'ulimit -c' command or other means otherwise no file will be created regardless of the value of this option.
