Met het programma Nagios Core kun je verschillende onderdelen van het netwerk en de services op je servers in de gaten houden. Het programma kan onder andere smtp-, pop3-, http- en nntp-services, en resources zoals de processorload en het diskgebruik controleren. Als er iets gebeurt waarvan je op de hoogte gehouden wil worden, kun je per mail of op je pager notificaties ontvangen. Voor meer informatie verwijzen we naar deze pagina en een rits screenshots is op deze pagina te bekijken. Daarnaast kun je dit GoT-topic doornemen.
