Azure Policies

Policy names are prefixed with Azure VM –

Policy name Metrics Required Duration Condition 1 (and) Condition 2 (and) Condition 3 Cat. Description
CPU Threshold Exceeded Boot Diagnostics 15 min Processor.PercentProcessorTime has a static threshold > 50% WARNING The CPU on the Azure Virtual Machine has exceeded 95% for at least 15 minutes.
Elevated CPU Activity (Normal Network Activity) Boot Diagnostics 30 min Processor.PercentProcessorTime has an upper baseline deviation + an upper contextual deviation + a static threshold > 20% NetworkInterface.BytesReceived has no deviation NetworkInterface.BytesTransmitted has no deviation INFO Increases in CPU activity are not uncommon when there is a rise in network activity. Increased traffic to a server means more work for that server to do. This policy is designed to catch cases where CPU activity is higher than than normal and said behavior cannot be explained by a corresponding increase in network traffic. It may or may not represent a problem, but it is useful to know about. This policy will not fire if CPU utilization is less than 20% though.
Elevated Disk Activity Boot Diagnostics 30 min PhysicalDisk.ReadsPerSecond has an upper baseline deviation + an upper contextual deviation PhysicalDisk.WritesPerSecond has an upper baseline deviation + an upper contextual deviation INFO Disk activity has been higher than expected for at least 30 minutes.
Elevated Memory Utilization Basic Metrics 15 min Memory.PercentUsedMemory has an upper baseline deviation + an upper contextual deviation WARNING The memory utilization on the Azure Virtual Machine is higher than expected.
Elevated Network Activity Boot Diagnostics 30 min NetworkInterface.BytesReceived has an upper baseline deviation + an upper contextual deviation NetworkInterface.BytesTransmitted has an upper baseline deviation + an upper contextual deviation INFO Network activity has been higher than expected for at least 30 minutes.
Heavy Disk Load Basic Metrics 5 min PhysicalDisk.AverageDiskQueueLength has an upper baseline deviation + an upper contextual deviation WARNING Average disk queue length is greater than expected, which could indicate a problem with heavy disk load.
