VMware vSAN Monitoring
Last updated on 17 March, 2023Overview
VMware vSAN is enterprise-class storage virtualization software that, when combined with vSphere, allows you to manage compute and storage with a single platform. It joins all storage devices across a vSphere cluster into a shared data pool, allowing you to scale up or down as your needs change.
Using LogicMonitor’s VMware vSAN package, you can monitor capacity disk performance; front- and back-end performance for vSan-enabled clusters and hosts; and more.
Compatibility
Some datapoints across the various DataSources in the VMware vSAN package may not be available for vSphere versions prior to 6.5.
Setup Requirements
Import LogicModules
From the LogicMonitor Repository, import all VMware vSAN LogicModules, which are listed in the LogicModules in Package section of this support article.
Duplicate Cluster Naming
vSAN allows multiple clusters to have the same names for similar cluster health tests. However, when multiple clusters are monitored by LogicMonitor, this translates to duplicate instance names, which is not supported (i.e. duplicate names are not discovered).
To ensure unique instance names and for searching the relevant clusters, you can add the custom property of “vsan.instanceformat” to the host and assign it a value of “dedupe” (case insensitive). This property appends the cluster ID to the test name (i.e. <test name> [cluster ID]) to avoid duplicate instance names.
If this property is set on a host that has already been running for a while, the history for the host will be lost. (only for that host).
Add Devices Into Monitoring
Add your VMware vSAN devices into monitoring. For more information on adding resources into monitoring, see Adding Devices.
Credentials
LogicMonitor uses the VMware API to provide comprehensive monitoring of many VMware products, including vSAN. For this reason, it must be able to provide the appropriate VMware API user account credentials in order to successfully access the API. If you’ve already established monitoring for VMware vCenter or standalone ESXi hosts, as detailed in ESXi Servers and vCenter/vSphere Monitoring, then a user account has already been established and it can be used for vSAN monitoring as well.
With a user account for the VMware API established, the following properties must be set on the VMware vSAN resource(s) within LogicMonitor. For more information on setting properties, see Resource and Instance Properties.
