vSphere ESXi Datastore Monitoring
This Host Template is part of the Vsphere Monitoring Opspack
Host Template: OS - VMware vSphere ESXi Datastore
Monitor your ESXi Datastores with a variety of checks including Provisioning status, Disk usage, Read/Write command monitoring and drive type/state. This Host Template includes support for VMware vMotion, so you can keep monitoring Datastores even if they are moved between Datacenters with no change to your Opsview configuration.
See all of the Opsview's virtualization monitoring solutions at VMware Monitoring.
This Host Template includes the following Service Checks:
| Service Check Name | Description | Default Thresholds (Warning, Critical) | UOM |
|---|---|---|---|
| vSphere - Datastore - Provisioning | The current provisioning status of the datastore - values over 100% indicate that the datastore is over-provisioned. | provisioned=100,120 | % |
| vSphere - Datastore - Disk Usage | The current datastore disk usage. | disk_usage=70,90 | % |
| vSphere - Datastore - Summary | The state of the datastore and the drive type. | N/A | N/A |
Usage Instructions
vMotion Support
To allow for vMotion support (moving Datastores between Datacenters without having to update your Host details), you must use the vCenter Credentials Variable listed in Step 2. Additionally, all Hosts utilized in vMotion must share login credentials to allow Opsview to maintain monitoring. The ESXi Host Name is optional if using vCenter Credentials.
When using vMotion, the ESXi Host containing the requested resource can be found automatically without needing to specify the Host the resource is on. However, this automatic retrieval of the Host will extend the runtime of the service checks and if performance is a concern, the Opsview Host configuration should be updated with the correct ESXi Host details.
Providing the vCenter Credentials variable will also allow for enhanced error handling when carrying out Service Checks.
Step 1: Add this Host Template
Add the OS - VMware vSphere ESXi Datastore Host Template to your Opsview Monitor host. If the resource you're monitoring has no hostname or public IP, then open the Advanced settings pane and change Host Check Command to Always assumed to be UP.
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:
VSPHERE_ESXI_DATASTORE_NAME
| Parameter | Position in Variable | Name | Description |
|---|---|---|---|
| Opsview UI Only | Value | ESXi Datastore Display Name | Display Name for Datastore Service Checks |
| --esxi-datastore-name | Arg1 | ESXi Datastore Name | Name of the ESXi Datastore |
VSPHERE_ESXI_CREDENTIALS
This variable is optional but either 'VSPHERE_ESXI_CREDENTIALS' or 'VSPHERE_VC_CREDENTIALS' needs to be set.
| Parameter | Position in Variable | Name | Description |
|---|---|---|---|
| --esxi-username | Arg1 | ESXi Username | Username for the ESXi Host |
| --esxi-password | Arg2 | ESXi Password | Password for the ESXi Host |
VSPHERE_ESXI_HOST_NAME
| Parameter | Position in Variable | Name | Description |
|---|---|---|---|
| Opsview UI Only | Value | ESXi Host Display Name | Display Name for ESXi Host Service Checks |
| --esxi-hostname | Arg1 | ESXi Host Name | Name of the ESXi Host |
VSPHERE_VC_CREDENTIALS
This variable is optional but either 'VSPHERE_ESXI_CREDENTIALS' or 'VSPHERE_VC_CREDENTIALS' needs to be set. Setting this variable allows for enhanced error handling when carrying out ESXi Service Checks.
| Parameter | Position in Variable | Name | Description |
|---|---|---|---|
| --vcenter-username | Arg1 | vCenter Username | Username for vCenter instance |
| --vcenter-password | Arg2 | vCenter Password | Password for vCenter instance |
| --vcenter-server | Arg3 | vCenter Instance Name | Name of the vCenter instance |
For more information, refer to Opsview Knowledge Center - Adding Variables to Hosts.
For mode-specific help, run the plugin with the -h -m <mode> flags. This will list the required and optional Variable Arguments for that mode. The appropriate mode for each Service Check is listed here:
| Service Check Name | Mode |
|---|---|
| vSphere - Datastore - Provisioning | ESXiDatastore.Provision |
| vSphere - Datastore - Disk Usage | ESXiDatastore.Usage |
| vSphere - Datastore - Summary | ESXiDatastore.Summary |
SSL Certificates
Additionally, you can use the following variable to pass in your SSL certificates for use when connecting to the service provider to gather metrics:
VSPHERE_CERTIFICATES
| Parameter | Position in Variable | Name | Description |
|---|---|---|---|
| --ca-path | Arg1 | CA Certificate Path | Path to the CA Certificate |
| --client-cert | Arg2 | Client Certificate Path | Path to the Client Certificate |
| --client-key | Arg3 | Client Key Path | Path to the Client Key |
Step 3: Apply changes and the system will now be monitored
