Mis on asi Logwatch
Logwatch on paindlik logide analüüsi tarkvara, mida vaikimisi käivitatakse kord ööpäevas(cron.daily) eelmise päeva logide analüüsimiseks.
Näiteid vaikimisi toetatud logi failidest
Vaikimisi toetab logwatch 94 süsteemi administraatorile teada tuntud rakenduse logide analüüsimist. Näitena toetatud rakendustest tooks välja:
*clamav *dhcpd *httpd *sshd *named *openvpn *syslogd *postfix *sudo *spamassassin *sendmail *yum *windows (windowsi eventlogi väljavõtted, mis on edastatud UNIX-il baseeruvale syslog serverile)
Lisaks vaikimisi toetatud rakendustele on võimalik lisada oma rakenduste logide analüüsi tugi kirjeldades logwatchis ära filtrid kuidas neid logisid analüüsida.

Eeldused
Kasutamise eelduseks on see, et kasutusel on mõni linuxi distributsioon, kus on seadistatud perli tugi.
Paigaldamine
Paigaldamise näide on toodud Ubuntu Linuxi põhjal. Logwatchi paigaldamiseks tuleb terminali sisestada järgmised käsud:
sudo apt-get update sudo apt-get install logwatch
Selle tulemusena paigaldatakse masinasse postfixi, perli ja logwatchi pakid.
Seadistamine
Selleks, et raporteid saadetaks e-postiga tuleb muuta /etc/cron.daily/00logwatch failis muuta logwatchi käivitamise parameetrid nõnda:
/usr/sbin/logwatch --mailto aadress@domeen.com
Logwatchi seadistamiseks tuleb muuta konfiguratsiooni faili:
sudo vim /usr/share/logwatch/default.conf/logwatch.conf
Vaikimisi analüüsib logwatch ka logide arhiive (näiteks /var/log/messages.1 või /var/log/messages.1.gz). Soovi korral saab seda välja lülitada, eemaldades konfiguratsiooni failis kirje Archives = No eest #. Analüüsitava ajavahemiku määramiseks on konfiguratsiooni failis muutujaga Range vaikimisi analüüsitakse eelmist päeva "yesterday". Raporteerimise taset on võimalik määrata vahemikus 0-10 või vastavalt sõnadega Low, Med, High.
