Host Template: Cloud - Azure - Virtual Machines Scale Sets VM
Overview Copied
Azure Virtual Machine Scale Sets allow you to deploy and manage a set of identical, auto-scaling, load balanced VMs. The number of VMs in the scale set can be scaled manually, or have pre-defined rules to autoscale based on resource usage, such as CPU, memory or network traffic. An Azure load balancer is used to distribute traffic to the VM instances in the scale set.
This Host Template includes the following Service Checks:
| Service Check Name | Description | Default Thresholds (Metric: Warning, Critical) | UOM |
|---|---|---|---|
| Azure - VMSSVM - Bytes Read Operations | The number of bytes read operations by the VMSSVM per second [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | per_second |
| Azure - VMSSVM - Bytes Read | The number of bytes read by the VMSSVM [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | B |
| Azure - VMSSVM - Bytes Write Operations | The number of bytes write operations by the VMSSVM per second [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | per_second |
| Azure - VMSSVM - Bytes Written | The number of bytes written by the VMSSVM [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | B |
| Azure - VMSSVM - Network In | The number of bytes received by the VMSSVM [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | B |
| Azure - VMSSVM - Network Out | The number of bytes sent by the VMSSVM [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | B |
| Azure - VMSSVM - Percentage CPU | The percentage CPU usage [Default Timespan = 5mins, Default Check Interval = 5mins] |
percentage_cpu: |
% |
Note
The “Default Timespan” given for these Service Checks refers to the time period we use when retrieving metrics from Azure.
