(emergency) – bu xabar dasturiy ta‘minotning yoki qurilmaning buzilishi
to‗g‗risida; bu turdagi xabar qurilmaning ishlamay qolganligini bildiradi. Syslogni
bu pog‗onasi jiddiy muammoga bog‗liq;
-
tekshrish pog‗onasi (debugging) – bu pog‗onadagi xabar debug ning turli
buyrug‗ini bajarish natijasida olingan chiqish ma‘lumotlaridan iborat;
-
ogohlantirish pog‗onasi (notification) – ogohlantirish pog‗onasidagi xabar
ma‘lumotnoma ko‗rinishidagi harakterga ega. Qurilmani ishlash qobiliyatiga ta‘sir
ko‗rsatmaydi. Ogohlantirish pog‗onasida xabar interfeysni holati aktiv yoki aktiv
emasligini yoki tizimni qayta ishga tushganligini ko‗rsatadi.
