Mark Salyzyn9c66a582015-12-14 16:40:12 -080024persist.logd.size number ro Global default size of the buffer for
Mark Salyzyn932f7ac2015-08-28 08:02:59 -070025 all log ids at initial startup, at
26 runtime use: logcat -b all -G <value>
Mark Salyzyn66607eb2016-01-05 08:49:44 -080027ro.logd.size number svelte default for persist.logd.size. Larger
28 platform default sizes than 256KB are
29 known to not scale well under log spam
30 pressure. Address the spam first,
31 resist increasing the log buffer.

35 default false, logd.size 64K instead
36 of 256K.

Mark Salyzynbec3c3d2015-08-28 08:02:59 -070039ro.logd.filter string "~! ~1000/!" default for persist.logd.filter.
Mark Salyzyn9c66a582015-12-14 16:40:12 -080040 This default means to prune the
Mark Salyzynbec3c3d2015-08-28 08:02:59 -070041 oldest entries of chattiest UID, and
42 the chattiest PID of system
43 (1000, or AID_SYSTEM).
Mark Salyzyn9c66a582015-12-14 16:40:12 -080044persist.logd.timestamp string ro The recording timestamp source.
45 "m[onotonic]" is the only supported
46 key character, otherwise realtime.
47ro.logd.timestamp string realtime default for persist.logd.timestamp
48log.tag string persist The global logging level, VERBOSE,
49 DEBUG, INFO, WARN, ERROR, ASSERT or
50 SILENT. Only the first character is
51 the key character.
52persist.log.tag string build default for log.tag
53log.tag.<tag> string persist The <tag> specific logging level.
54persist.log.tag.<tag> string build default for log.tag.<tag>

64- persist - <base property> override, persist.<base property> platform default.
65- build - VERBOSE for native, DEBUG for jvm isLoggable, or developer option.
66- number - support multipliers (K or M) for convenience. Range is limited
Mark Salyzyn932f7ac2015-08-28 08:02:59 -070067 to between 64K and 256M for log buffer sizes. Individual log buffer ids
68 such as main, system, ... override global default.
69- Pruning filter is of form of a space-separated list of [~][UID][/PID]
70 references, where '~' prefix means to blacklist otherwise whitelist. For
Mark Salyzynbec3c3d2015-08-28 08:02:59 -070071 blacklisting, UID or PID may be a '!' to instead reference the chattiest
72 client, with the restriction that the PID must be in the UID group 1000
73 (system or AID_SYSTEM).
