Your virtual machine shares resources with other virtual machines on a hypervisor (the server that is hosting the virtual machines). CPU Steal is the amount of time your virtual CPU has to wait for a real CPU from the hypervisor. This happens when a neighbour VM is using up all the real CPU of the hypervisor. CPU Steal is an important metric to monitor in case you're using virtualized servers. It can have significant impact on the performance of your machine.

Your team needs to know quickly when there are production problems either with the app itself or with your backend services so you can fix the issue before more customers are impacted.

We’ve added the ability to receive Pushover notifications for all our services. Our notification system already supports Slack, email, SMS, voice call, PagerDuty and webhooks, but following feedback from our customers we felt Pushover provided extra functionality for smarter notifications.
