| 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.organization_owned 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). |
| 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> |
| |
| logd.buffer_type string (empty) Set the log buffer type. Current choices are 'simple', |
| 'chatty', or 'serialized'. Defaults to 'chatty' if empty. |
| |
| 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 rules are specified as UID, UID/PID or /PID. A '~' prefix indicates that elements |
| matching the rule should be pruned with higher priority otherwise they're pruned with lower |
| priority. All other pruning activity is oldest first. Special case ~! represents an automatic |
| pruning for the noisiest UID as determined by the current statistics. Special case ~1000/! |
| represents pruning of the worst PID within AID_SYSTEM when AID_SYSTEM is the noisiest UID. |
