Possible commands that can be executed on a given resource. Ultimate subscription is required.
| Command Type | Description | |
|---|---|---|
| AzureCloudServiceInstanceReboot | Reboots specified Azure Cloud Service instance | |
| AzureCloudServiceInstanceReimage | Reimages specified Azure Cloud Service instance | |

CloudMonix provided default monitoring templates.
| Metric Name | Metric Type | Description |
|---|---|---|
| ApplicationEventLogs | WindowsEventLogEntry | Tracks entries from the Windows Event Log (Application source) |
| AspNetApplicationRestarts | WindowsPerformanceCounter | Tracks the number of times that an application has been restarted during the Web server's lifetime. Application restarts are incremented each time an Application_OnEnd event is raised. An application restart can occur because of changes to the Web.config file, changes to assemblies stored in the application's Bin directory, or when an application must be recompiled due to numerous changes in ASP.NET Web pages. Unexpected increases in this counter can mean that problems are causing Web application to recycle. |
| AspNetBytesOut | WindowsPerformanceCounter | Tracks total size in bytes of responses sent to a client. Does not include HTTP response headers. |
| AspNetErrors | WindowsPerformanceCounter | Tracks the average number of errors that occurred per second during the execution of HTTP requests. Includes any parser, compilation, or run-time errors. |
| AspNetRequests | WindowsPerformanceCounter | Tracks the number of requests executed per second. This represents the current throughput of the application. Under constant load, this number should remain within a certain range, barring other server work (such as garbage collection, cache cleanup thread, external server tools, and so on). |
| AspNetRequestsQueued | WindowsPerformanceCounter | Tracks the number of requests waiting for service from the queue. When this number starts to increment linearly with increased client load, the Web server computer has reached the limit of concurrent requests that it can process. |
| AspNetRequestsRejected | WindowsPerformanceCounter | Tracks the total number of requests not executed because of insufficient server resources to process them. This counter represents the number of requests that return a 503 HTTP status code, indicating that the server is too busy |
| AspNetRequestWaitTime | WindowsPerformanceCounter | Tracks the number of milliseconds that the most recent request waited in the queue for processing |
| CpuTime | WindowsPerformanceCounter | Tracks overall CPU utilization on the monitored server |
| CpuTime30MinAverage | AggregatedMetric | Tracks 30-minute CPU utilization average across all instances within monitored Cloud Role |
| DiskFree | WindowsPerformanceCounter | Tracks amount of free space across all drives in megabytes |
| DiskIdleTime | WindowsPerformanceCounter | Tracks the percentage of time when disk. Sustained numbers below 20% indicate an over-saturated disk. |
| DiskReadSpeed | WindowsPerformanceCounter | Tracks average time, in seconds, it takes to read data from the disk |
| DiskWriteSpeed | WindowsPerformanceCounter | Tracks average time, in seconds, it takes to write data to the disk |
| InstanceList | AzureCloudRoleInstanceDetails | Metric is tracking detailed status of monitored cloud role instances |
| MemoryCommittedPct | WindowsPerformanceCounter | Tracks the amount of virtual memory in use. It is the ratio of Commited Bytes to the Commit Limit |
| MemoryFree | WindowsPerformanceCounter | Tracks free memory (in MBs) on the monitored server |
| Status | ResourceStatus | Tracks the overall readiness status of the monitored resource. Possible values are: Ready, Down, Stopped and Unknown |
| SystemEventLogs | WindowsEventLogEntry | Tracks entries from the Windows Event Log (System source) |
| SystemUptime | WindowsPerformanceCounter |
