Management wants uptime and system performance data monthly (CPU) for our systems which consist of a mixture of linux/unix/windows machines. Anything out there that might provide this information?
PS: what I am looking for is a simple monthly uptime/downtime calculation. In terms of performance, maybe only just the average CPU use over the month just a single number perhaps, maybe average disk use over the month. Not a monitoring system really, just something to record this easily over the broad range of systems we have. Something very simple but easy and fast to implement without very much human overhead.
