1 The properties that logd and friends react to are: 2 3 name type default description 4 ro.logd.auditd bool true Enable selinux audit daemon 5 ro.logd.auditd.dmesg bool true selinux audit messages sent to dmesg. 6 ro.logd.auditd.main bool true selinux audit messages sent to main. 7 ro.logd.auditd.events bool true selinux audit messages sent to events. 8 persist.logd.security bool false Enable security buffer. 9 ro.device_owner bool false Override persist.logd.security to false 10 ro.logd.kernel bool+ svelte+ Enable klogd daemon 11 ro.logd.statistics bool+ svelte+ Enable logcat -S statistics. 12 ro.debuggable number if not "1", logd.statistics & 13 ro.logd.kernel default false. 14 logd.logpersistd.enable bool auto Safe to start logpersist daemon service 15 logd.logpersistd string persist Enable logpersist daemon, "logcatd" 16 turns on logcat -f in logd context. 17 Responds to logcatd, clear and stop. 18 logd.logpersistd.buffer persist logpersistd buffers to collect 19 logd.logpersistd.size persist logpersistd size in MB 20 persist.logd.logpersistd string Enable logpersist daemon, "logcatd" 21 turns on logcat -f in logd context. 22 persist.logd.logpersistd.buffer all logpersistd buffers to collect 23 persist.logd.logpersistd.size 256 logpersistd size in MB 24 persist.logd.size number ro Global default size of the buffer for 25 all log ids at initial startup, at 26 runtime use: logcat -b all -G <value> 27 ro.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. 32 persist.logd.size.<buffer> number ro Size of the buffer for <buffer> log 33 ro.logd.size.<buffer> number svelte default for persist.logd.size.<buffer> 34 ro.config.low_ram bool false if true, logd.statistics, 35 ro.logd.kernel default false, 36 logd.size 64K instead of 256K. 37 persist.logd.filter string Pruning filter to optimize content. 38 At runtime use: logcat -P "<string>" 39 ro.logd.filter string "~! ~1000/!" default for persist.logd.filter. 40 This default means to prune the 41 oldest entries of chattiest UID, and 42 the chattiest PID of system 43 (1000, or AID_SYSTEM). 44 persist.logd.timestamp string ro The recording timestamp source. 45 "m[onotonic]" is the only supported 46 key character, otherwise realtime. 47 ro.logd.timestamp string realtime default for persist.logd.timestamp 48 log.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. 52 persist.log.tag string build default for log.tag 53 log.tag.<tag> string persist The <tag> specific logging level. 54 persist.log.tag.<tag> string build default for log.tag.<tag> 55 56 NB: 57 - auto - managed by /init 58 - bool+ - "true", "false" and comma separated list of "eng" (forced false if 59 ro.debuggable is not "1") or "svelte" (forced false if ro.config.low_ram is 60 true). 61 - svelte - see ro.config.low_ram for details. 62 - svelte+ - see ro.config.low_ram and ro.debuggable for details. 63 - ro - <base property> temporary override, ro.<base property> platform default. 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 67 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 71 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). 74
