Dell SC Monitoring

Overview

Dell SC is a storage system branded as Dell Storage Center or Dell EMC Storage Center. LogicMonitor offers out-of-the-box monitoring for Dell SC based systems, allowing you to monitor various metrics for the storage devices including fan RPM, fan status, temperature, disk status, health status, global object count statistics, and more.

Compatibility

As of May 2020, LogicMonitor’s package for Dell SC is compatible with the following Dell SC based systems and supports the following models:

• Dell Compellent (SC4020, series 40)
• Dell Storage (SC5020, SC5020F, SC7020, SC7020F, SC8000, SC9000, SCv300, SCv360, SCv2000, SCv2020, SCv2080, SCv3000, SCv3020, SCv3200).

Note: As discussed in the Migration from Dell Compellent to Dell SC LogicModules section of this support article, you must use the Dell SC package (and not our Dell Compellent LogicModules) to monitor any of the above-listed systems. However, you should (continue to) use our Dell Compellent LogicModules to monitor any Compellent systems not listed above.

Setup Requirements

Add Resource Into Monitoring

Add your Dell SC devices into monitoring. The device’s IP or hostname must be entered into the IP Address/DNS name field or monitoring will fail. For more information on adding resources into monitoring, see Adding Devices. ​

Enable SNMP

SNMP must be configured on the Dell SC host in order for the DataSources to successfully collect data. For more information on the SNMP values used, see Dell Storage Center Operating Systems (MIB).​

Enter SNMP Credentials

LogicMonitor must provide the appropriate credentials in order to successfully access the Dell SC system via SNMP. For instructions on how to set the appropriate credentials as properties on the resource within LogicMonitor, see Defining Authentication Credentials. ​​

Import LogicModules

From the LogicMonitor repository, import all Dell SC 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.

Once the LogicModules are imported (assuming all previous setup requirements have been met), the suite of Dell SC LogicModules will automatically begin collecting data.

Migration from Dell Compellent to Dell SC LogicModules

The Dell SC monitoring package (all DataSource names in this package are prepended with “Dell_SC”) is intended to replace all Dell Compellent and Dell SC Compellent LogicModules (names are prepended with “Dell_Compellent” and “Dell_SC_Compellent” respectively) for monitoring of any of the above-listed systems.

The Dell SC monitoring package was added because, in recent hardware, it’s been discovered that the discovery and collection of important data such as temperature, fans, fan status, and other data has become unreliable as Dell transitions away from the older 1.3.6.1.4.1.16139 Compellent technologies OID to the newer 1.3.6.1.4.1.674.11000.2000.500.1 Dell Storage Center OID. The Dell SC package uses only the latter OID for discovery and collection.

You may see duplicate alerts if you are monitoring compatible Dell SC devices with both the newer Dell SC DataSources and the older Dell (SC) Compellent DataSources. For this reason, we recommend that you disable any Dell Compellent DataSources after importing the new set of Dell SC DataSources and confirming that they are working as intended in your environment.

When a DataSource is disabled, it stops querying the host and generating alerts, but maintains all historical data. At some point in time, you may want to delete the DataSources altogether, but consider this move carefully as all historical data will be lost upon deletion. For more information on disabling DataSources, see Disabling Monitoring for a DataSource or Instance.

Note: The new Dell SC package does not work with older Compellent systems (see list of supported models in the Compatibility section of this support article) so if you would like to continue monitoring these older systems, do not disable the associated Compellent DataSources.

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.
