Logcatd has capability to output logs to filesystem with certain size and certain file count, however file size is not configurable, fixed as 1024 kbytes, file count is configurable, but original property name didn't match the logcat parameter well. This patch add interface rotate_kbytes and count into logcatd.rc. rotate_kbytes used to control each logcat file size. count is another alias for logd.logpersistd.size to control file number. Bug: 133362078 Test: Can use logcat -r -n with configures Change-Id: I9954c9c125a4ab4e49310986f81c734bf8ee96b3 Signed-off-by: Tian, Baofeng <baofeng.tian@intel.com> Signed-off-by: Duan, YayongX <yayongx.duan@intel.com>

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.
|
|
ro.logd.auditd.events bool true selinux audit messages sent to events.
|
|
persist.logd.security bool false Enable security buffer.
|
|
ro.device_owner bool false Override persist.logd.security 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
|
|
logd.logpersistd.rotate_kbytes persist logpersistd outout file size in KB.
|
|
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.logpersistd.count 256 sets max number of rotated logs to <count>.
|
|
persist.logd.logpersistd.rotate_kbytes 1024 logpersistd output file size in KB
|
|
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,
|
|
ro.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,
|
|
DEBUG, INFO, WARN, ERROR, ASSERT or
|
|
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>
|
|
|
|
NB:
|
|
- 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
|
|
true).
|
|
- 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).
