I work for an MSP in Europe and am in charge of pretty much everything technical.
We had a conversation the other day which could be added to what we are currently monitoring.
We had ideas like active SIP trunk connection (status, quality) and log monitoring of SIP trunks at phone systems, Windows account creation (local, domain, group membership monitoring, open files (unusual patterns), processes accessing the webcam (anti-spy) etc.
What do you monitor with your customers?
Info: Some of the ideas above even come from customers
You need to look into zabbix. You can monitor pretty much anything you please. I use it for monitoring an entire data center and everything in between. SQL, windows server, Linux server, networking, network ports, SANs storage and so on. Needless to say if something breaks then I would know as soon as it happens. So ideas on what to monitor. Depends on the customers needs but I would think to monitor critical services running on said servers. I would monitor drive space on servers, CPU utilization, memory, UPS’s (if they kick on or not to monitor power loss), temperature And humidity in the server room and high and critical event logs.
