5.1 Dhaptar saringan
Logger ngidini sampeyan ngatur nyaring pesen kanthi apik. Kanggo nindakake iki, dheweke duwe sawetara rolas saringan kanthi macem-macem parameter. Tabel ing ngisor iki nuduhake sing paling populer.
| Filter-filter | Katrangan | |
|---|---|---|
| 1 | BurstFilter | Ngidini sampeyan ngontrol frekuensi pesen per detik kanggo level logging tartamtu. |
| 2 | Filter Komposit | Ngidini sampeyan nyetel sawetara saringan urutan. |
| 3 | DynamicThresholdFilter | Ngidini sampeyan ngaktifake logging rinci yen informasi tartamtu ditemokake ing log. |
| 4 | MapFilter | Ngidini sampeyan mbangun ekspresi logis sing kompleks kanggo panyaring saka sawetara paramèter. |
| 5 | PenandaFilter | Ngidini sampeyan nyaring pesen miturut tag, tag kasebut kudu ditambahake dhisik sajrone logging acara. |
| 6 | RegexFilter | Ngidini sampeyan nyetel topeng - ekspresi biasa. |
| 7 | StructuredDataFilter | Ngidini sampeyan nyaring pesen kanthi anané data tartamtu. |
| 8 | ThreadContextMapFilter | Ngidini sampeyan ngatur saringan adhedhasar data sing dijupuk saka konteks utas saiki. |
| 9 | ThresholdFilter | Kontrol logging adhedhasar level pesen log. |
| 10 | WektuFilter | Ngidini sampeyan ngaktifake lan mateni saringan ing wektu tartamtu. |
Ing ngisor iki kita bakal ngomong babagan mung telu. Sampeyan bisa sinau luwih lengkap babagan saringan kasebut ing situs web resmi .
5.2 Filter Wektu
Filter kasebut TimeFilterngidini sampeyan ngaktifake lan mateni saringan ing wektu tartamtu, ana 5 parameter:
| 1 | miwiti | Wektu wiwitan logging ing formatHH:mm:ss |
| 2 | pungkasan | Wektu log off ing formatHH:mm:ss |
| 3 | zona wektu | Nyetel zona wektu. |
| 4 | onMatch | Carane log yen kondisi filter bener . Mungkin ACCEPT, DENYutawa NEUTRAL. Default NEUTRAL. |
| 5 | ing Mismatch | Carane mlebu log yen kondisi filter salah . Mungkin ACCEPT, DENYutawa NEUTRAL. Default NEUTRAL. |
Ayo nyiyapake saringan sing bakal nguripake logging jam 5 esuk lan mateni jam 5:30 saben dina. Conto kanthi konfigurasi filter lengkap ing ngisor iki:
<?xml version="1.0" encoding="UTF-8"?>

<Appenders>
<RollingFile name="RollingFile" fileName="logs/app.log" filePattern="logs/app-%d{MM-dd-yyyy}.log.gz">
<TimeFilter start="05:00:00" end="05:30:00" onMatch="ACCEPT" onMismatch="DENY"/>
<PatternLayout>
<pattern>%d %p %c{1.} [%t] %m%n</pattern>
</PatternLayout>
<TimeBasedTriggeringPolicy />
</RollingFile>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="RollingFile"/>
</Root>
</Loggers>
</Configuration>5.3 RegexFilter
Filter RegexFilterngidini sampeyan nyetel topeng (ekspresi reguler) kanggo nyaring pesen. Filter iki duwe 4 parameter:
| 1 | regex | Nemtokake ekspresi reguler - topeng sing digunakake kanggo nyaring pesen.HH:mm:ss |
| 2 | nggunakakeRawMsg | Topeng ditrapake ing pesen sadurunge format (bener) utawa sawise format (salah) |
| 3 | onMatch | Carane log yen kondisi filter bener . Mungkin ACCEPT, DENYutawa NEUTRAL. Default NEUTRAL. |
| 4 | ing Mismatch | Carane mlebu log yen kondisi filter salah . Mungkin ACCEPT, DENYutawa NEUTRAL. Default NEUTRAL. |
Ayo nyiyapake saringan sing mung ngidini pesen sing ngemot tembung codegym. Conto kanthi konfigurasi filter lengkap ing ngisor iki:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn" name="MyApp" packages="">
<Appenders>
<RollingFile name="RollingFile" fileName="logs/app.log" filePattern="logs/app-%d{MM-dd-yyyy}.log.gz">
<RegexFilter regex=".* codegym .*" onMatch="ACCEPT" onMismatch="DENY"/>
<PatternLayout>
<pattern>%d %p %c{1.} [%t] %m%n</pattern>
</PatternLayout>
<TimeBasedTriggeringPolicy />
</RollingFile>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="RollingFile"/>
</Root>
</Loggers>
</Configuration>5.4 Ambang Filter
Filter ThresholdFilter ngidini sampeyan ngatur nyaring miturut level pesen. Ana mung 3 parameter:
| 1 | tingkat | Nyetel jeneng level logging pesen: ERROR, DEBUG,… |
| 2 | onMatch | Carane log yen kondisi filter bener . Mungkin ACCEPT, DENYutawa NEUTRAL. Default NEUTRAL. |
| 3 | ing Mismatch | Carane mlebu log yen kondisi filter salah . Mungkin ACCEPT, DENYutawa NEUTRAL. Default NEUTRAL. |
Ayo nyiyapake saringan sing mung ngidini pesen level DEBUG. Conto kanthi konfigurasi filter lengkap ing ngisor iki:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn" name="MyApp" packages="">
<Appenders>
<RollingFile name="RollingFile" fileName="logs/app.log" filePattern="logs/app-%d{MM-dd-yyyy}.log.gz">
<ThresholdFilter level="DEBUG" onMatch="ACCEPT" onMismatch="DENY"/>
<PatternLayout>
<pattern>%d %p %c{1.} [%t] %m%n</pattern>
