anonimowy blog

A oto prosty sposób aby na bierząco monitorowac działanie squida, przy wykorzystaniu konfiguracji opisanej na blogu w jednym z poprzednich wpisów.

Ja do tego celu wykorzystuję MRTG, które to poprzez SNMP uzyskuje porządane informacje oraz generuje ładne i czytelne wykresy:

Poniżej wycinek z mrtg.cfg

W następnym odcinku podziele się skryptami, które wszczynaja alarm gdy proxy wariuje.

P.S. A może nie podziele się ?
