Host Template: Cloud - Azure - Network Watcher - VM Connectivity

This host template is one of 31 developed by Opsview to provide the most comprehensive Azure monitoring in the industry.

Azure Network Watchers allow you to monitor, diagnose, view metrics, and enable or disable logs for resources in an Azure virtual network. You can monitor communication between virtual machines and endpoints, and view the relationships between resources in a virtual network. Additionally, you can capture packets, troubleshoot and diagnose problems inside a virtual network.

This Host Template allows you to monitor the connectivity between two VMs using a Network Watcher.

This Host Template includes the following Service Checks:

Service Check Name Description Default Thresholds (Warning, Critical) UOM
Azure - Network Watcher - VM Connectivity Check the status of TCP connection from a source VM to a target VM in Azure via a Network Watcher [Default Timespan = 5mins, Default Check Interval = 5mins] N/A NA

NOTE: The "Default Timespan" given for these Service Checks refers to the time period we use when retrieving metrics from Azure.

NOTE: See details about Nagios thresholds here.

For more information, refer to Opsview Knowledge Center - Adding Host Templates to Hosts.

Step 2: Add and configure variables required for this Host Template

The Service Checks in this Host Template use the following variables, and they will be added to your Opsview Monitor instance when you import the Opspack:
