idevicesyslog(1) General Commands Manual idevicesyslog(1) NAME idevicesyslog - Relay syslog of a connected device. SYNOPSIS idevicesyslog [OPTIONS] DESCRIPTION Relay syslog of a connected device. OPTIONS -u, --udid UDID target specific device by UDID -n, --network connect to network device -x, --exit exit when device disconnects -d, --debug enable communication debugging -h, --help prints usage information -v, --version Prints version information. --no-colors disable colored output -o, --output FILE Write to FILE instead of stdout. This will disable writing colored output, but can be re-enabled with --colors. If FILE already ex- ists, it will be overwritten without warning. --colors Force writing colored output, e.g. when using --output. --syslog-relay Use old syslog_relay service instead of os_trace_relay (iOS 9+). COMMANDS pidlist Print a list with PID and name of all processes currently running on the device. archive PATH Request a logarchive from the device. It will be written in tar for- mat to PATH. To pipe to another process use - as PATH. Below are some options to restrict the log message data. In order to view the logarchive in a compatible log viewer, you can pipe the output data to tar and have it extract into a new direc- tory: mkdir test.logarchive && tools/idevicesyslog archive - |tar -C test.logarchive -xv This will also print the filenames while they are extracted. Further options for archive: --start-time VALUE Start time of the log data as UNIX timestamp. Earlier messages will be dropped. --age-limit VALUE Maximum age of the log data, supposedly number of days. --size-limit VALUE Limit the size of the archive. The unit is currently unknown, so feel free to experiment. Keep in mind that the device usually only has a backlog of a few minutes so the options might not have the desired effect. This is not a bug. FILTER OPTIONS -m, --match STRING only print messages that contain STRING -M, --unmatch STRING print messages that do not contain STRING -t, --trigger STRING start logging when matching STRING When specified, logging will start as soon as a log messages is en- countered that contains the given string. See also -T, --untrigger. Other filters are still applied but obviously filtered messages are only printed after logging has started. -T, --untrigger STRING stop logging when matching STRING When specified logging will halt as soon as a log message is encoun- tered that contains the given string. See also -t, --trigger. Other filters are still applied but obviously filtered messages are only printed before logging stops. NOTE: If no --trigger is given, idevicesyslog will exit after a matching log message was encountered. -p, --process PROCESS only print messages from matching process(es) PROCESS is a string that can either be a numeric pid or a process name. It also supports multiple process names or pids in one string, separated by | (make sure to use quotes!). -e, --exclude PROCESS print all messages except matching process(es) PROCESS is a string that can either be a numeric pid or a process name. It also supports multiple process names or pids in one string, separated by | (make sure to use quotes!). -q, --quiet set a filter to exclude common noisy processes Since the syslog can be quite noisy, this quick command line switch allows silencing a predefined set of commonly known processes. The list of processes that are silenced can be retrieved with --quiet-list. --quiet-list prints the list of processes for --quiet and exits -k, --kernel only print kernel messages This is actually equivalent to passing --process kernel with the ex- ception that it can be used with --quiet to silence out the noisy process but still get all the kernel log messages. -K, --no-kernel suppress kernel messages This is equivalent to passing --exclude kernel. EXAMPLES idevicesyslog -u 00008030-0000111ABC000DEF Relay syslog of device with UDID 00008030-0000111ABC000DEF. idevicesyslog -x Relay syslog of device and exit when the device is unplugged. idevicesyslog -m '####' -e 'identityservicesd' -K Only print log messages that contain the string #### and do NOT originate from identityservicesd or the kernel. idevicesyslog -p MyApp -p ReportCrash Only print log messages from the process named 'MyApp' and 'Report- Crash'. idevicesyslog -p 'MyApp|ReportCrash' Same as previous example with different syntax. idevicesyslog -e 'backboardd|CommCenter|mDNSResponder' Suppress log messages from backboardd, CommCenter, and mDNSRespon- der. idevicesyslog -q -k Suppress log messages from common noisy processes, but DO print ker- nel log messages. idevicesyslog -K Suppress log messages from kernel, but print everything else idevicesyslog -t 'backlight on' -T 'backlight off' -q Start logging when the device turns on backlight and stop logging when it turns backlight off, and suppress noisy processes AUTHORS Nikias Bassen, Martin Szulecki Man page written to conform with Debian by Julien Lavergne.
