As you know both OMS Linux and Windows agent send heartbeat events and they are free of charge. The problem is that the interval of these heartbeat events is different for both operating systems. For Windows it is every 1 minute and for Linux is every 5 minutes. I do not know exactly the reason for this decision but I prefer that all my servers report at the same interval.

Mitigate speculative execution side-channel vulnerabilities

Free E-book: Inside #MSOMS v2 now available

It took us some time but we’ve managed to update the one and only free OMS book. We had plans to release it earlier but unforeseen things has happened which prevented us to do it earlier. I hope you will understand but you will still enjoy it. The other authors and me put a lot of effort to get it out along with the reviewers.
