LogicMonitor’s Dell PowerVault ME4 monitoring package leverages the Dell EMC REST API to monitor the health and performance metrics of the PowerVault ME4 Storage Area Network. LogicMonitor also alerts on the status and health information gathered from the REST API.
Add Resources into Monitoring
Add your Dell PowerVault ME4 hosts into monitoring. For more information on adding resources into monitoring, see Adding Devices.
LogicMonitor must provide the appropriate credentials in order to successfully access the PowerVault ME4 resource’s data. The credentials must have at least a read-only access to the API.
Assign Properties to Resources
The following custom properties must be set on the Dell PowerVault ME4 resource within LogicMonitor. For more information on setting properties, see Resource and Instance Properties.
|powervault.user||REST API username|
|powervault.pass||REST API password|
The modules in this suite support HTTP connections using a proxy server. You can configure this in the Collector settings, see Configuring your Collector for use with HTTP Proxies, or with the following device host properties. Device host properties take precedence over Collector settings for proxy configurations.
|proxy.enable||(Optional) This suite is written to use collector proxy settings for HTTP calls configured by the user. To enable, add this device property with the value set to true. Set to false to override the use of configured collector proxy settings and connect without a proxy.|
|proxy.host||(Optional) Configure a proxy host to connect through that is different from collector configuration.|
|proxy.port||(Optional) Configure a proxy port to connect through that is different from collector configuration.|
From the LogicMonitor public repository, import all Dell PowerVault ME4 LogicModules, which are listed in the LogicModules in Package section of this support article. If these LogicModules are already present, ensure you have the most recent versions. Data collection will automatically start after all the LogicModules are imported.
The modules in this package are designed with a debug mode embedded in the data collection scripts. If issues occur, turn on debug mode by setting the variable debug to “true” to get more information in the output when testing the script in the Collector Debug Facility. For more information on testing scripts in the Collector Debug Facility, see Script Troubleshooting.
Migration from Legacy LogicModules
If you are currently monitoring Dell PowerVault ME4 controller ports, updating from version 1.0 to version 1.1 will cause data loss to Compact Flash and Controller Expander instances.
LogicModules in Package

When setting static datapoint thresholds on the various metrics tracked by this package’s DataSources, LogicMonitor follows the technology owner’s best practice KPI recommendations. If necessary, we encourage you to adjust these predefined thresholds to meet the unique needs of your environment. For more information on tuning datapoint thresholds, see Tuning Static Thresholds for Datapoints.
