The properties that logd and friends react to are:
name type default description
ro.logd.auditd bool true Enable selinux audit daemon
ro.logd.auditd.dmesg bool true selinux audit messages sent to dmesg.
ro.logd.auditd.main bool true selinux audit messages sent to main. bool true selinux audit messages sent to events. bool false Enable security buffer.
ro.device_owner bool false Override to false
ro.logd.kernel bool+ svelte+ Enable klogd daemon
ro.logd.statistics bool+ svelte+ Enable logcat -S statistics.
ro.debuggable number if not "1", logd.statistics &
ro.logd.kernel default false.
logd.logpersistd.enable bool auto Safe to start logpersist daemon service
logd.logpersistd string persist Enable logpersist daemon, "logcatd"
turns on logcat -f in logd context.
Responds to logcatd, clear and stop.
logd.logpersistd.buffer persist logpersistd buffers to collect
logd.logpersistd.size persist logpersistd size in MB
persist.logd.logpersistd string Enable logpersist daemon, "logcatd"
turns on logcat -f in logd context.
persist.logd.logpersistd.buffer all logpersistd buffers to collect
persist.logd.logpersistd.size 256 logpersistd size in MB
persist.logd.size number ro Global default size of the buffer for
all log ids at initial startup, at
runtime use: logcat -b all -G <value>
ro.logd.size number svelte default for persist.logd.size. Larger
platform default sizes than 256KB are
known to not scale well under log spam
pressure. Address the spam first,
resist increasing the log buffer.
persist.logd.size.<buffer> number ro Size of the buffer for <buffer> log
ro.logd.size.<buffer> number svelte default for persist.logd.size.<buffer>
ro.config.low_ram bool false if true, logd.statistics, logd.kernel
default false, logd.size 64K instead
of 256K.
persist.logd.filter string Pruning filter to optimize content.
At runtime use: logcat -P "<string>"
ro.logd.filter string "~! ~1000/!" default for persist.logd.filter.
This default means to prune the
oldest entries of chattiest UID, and
the chattiest PID of system
(1000, or AID_SYSTEM).
persist.logd.timestamp string ro The recording timestamp source.
"m[onotonic]" is the only supported
key character, otherwise realtime.
ro.logd.timestamp string realtime default for persist.logd.timestamp
log.tag string persist The global logging level, VERBOSE,
SILENT. Only the first character is
the key character.
persist.log.tag string build default for log.tag
log.tag.<tag> string persist The <tag> specific logging level.
persist.log.tag.<tag> string build default for log.tag.<tag>
- auto - managed by /init
- bool+ - "true", "false" and comma separated list of "eng" (forced false if
ro.debuggable is not "1") or "svelte" (forced false if ro.config.low_ram is
- svelte - see ro.config.low_ram for details.
- svelte+ - see ro.config.low_ram and ro.debuggable for details.
- ro - <base property> temporary override, ro.<base property> platform default.
- persist - <base property> override, persist.<base property> platform default.
- build - VERBOSE for native, DEBUG for jvm isLoggable, or developer option.
- number - support multipliers (K or M) for convenience. Range is limited
to between 64K and 256M for log buffer sizes. Individual log buffer ids
such as main, system, ... override global default.
- Pruning filter is of form of a space-separated list of [~][UID][/PID]
references, where '~' prefix means to blacklist otherwise whitelist. For
blacklisting, UID or PID may be a '!' to instead reference the chattiest
client, with the restriction that the PID must be in the UID group 1000
(system or AID_SYSTEM).
