Syslog
Syslog on utiliit, mis genereerib logifailid ning saadab need Linxi süsteemi logifaili, mis asub /var/log/ kaustas, kus neid omakorda analüüsitakse. Syslog'i teateid saadavad välja erinevad võrguseadmed: ruuterid, switchid jms. Syslog'i teated sisaldavad tavaliselt informatsiooni: kus, millal ja miks teade saadeti.

| 5 | syslog | messages generated internally by syslogd |
| 6 | lpr | line printer subsystem |
| 7 | news | network news subsystem |
| 8 | uucp | UUCP subsystem |

Probleemide raskusastmed
| Väärtus | Raskusaste | Võtmesõna | Kirjeldus | Näited |
|---|---|---|---|---|
| 0 | Emergency | emerg | Süsteem on kasutuskõlbmatu | This level should not be used by applications. |
| 1 | Alert | alert | Tuleb koheselt korda teha | Loss of the primary ISP connection. |
| 2 | Critical | crit | Kriitiline seisund | A failure in the system's primary application. |
| 3 | Error | err | Error conditions | An application has exceeded its file storage limit and attempts to write are failing. |
| 4 | Warning | warning | May indicate that an error will occur if action is not taken. | A non-root file system has only 2GB remaining. |
| 5 | Notice | notice | Events that are unusual, but not error conditions. | |
| 6 | Informational | info | Normal operational messages that require no action. | An application has started, paused or ended successfully. |
| 7 | Debug | debug | Information useful to developers for debugging the application. |
