I want to know if there is software that can monitor network problems
Recently my web server had an issue where we were not receiving any e-mail.but we could send so this is why this went un-noticed for so long
no one really noticed until hours later. So after looking at what was wrong, we could not contact the mail server from the uoutside. No big deal, reboot and problem fixed. But I would have loved to have known much sooner.
Is there a software that can monitor from the outside and check specific ports or ip addresses like my mail.mydomain.com and let me know if there are problems?
Everynow and then my file server will not go down but rather you can't get files you can navigate to them, but when you try and open them they are unavailable or can't be opened like the server is down.
I have LAN monitoring software but since the server is actually up and running and I can log into it its technically not down.
This is not such a big deal since so many people use this server I know when its not working right within minutes. But I would still like to know before suoervisors start calling me freaking out.
Any suggestions are greatly appreciated.
