Hi guys ! I have a ISPConfig server with + than 200 websites. I was in trouble to monitor everything, and most of times the client who checked that their website was offline. This was causing me some problems, as downtime and sad clients. Hard to monitor, because i cant just open site-by-site to check if everything is OK. I found a guy who is ISPConfig specialist, and now automatically check every 2 minutes all my websites and report me (or me and client ) via whatsapp / telegram / email / SMS if something is down. Also, monitor default servers parameters, like disk size, CPU usage, slow mysql querys, logs, memory usage, services (FTP, mysql, nginx, postfix, etc) and report me immediately if something is down. So if someone have this type of problem, tell me here and i'll be happy to share this guy who can help us! Thank you all!
