Enabling Hardware Monitoring for Dell PowerEdge Linux Hosts

Hardware-specific monitoring is available for Dell PowerEdge Linux hosts with Enterprise Manager. To enable the hardware monitoring of your Dell PowerEdge Linux hosts, perform the following steps:

1. Download the latest Dell OpenManage Server Administrator (OMSA) software certified for your Linux OS by accessing the Dell FTP site at http://downloads.dell.com.

   To identify the latest OMSA software, search for the latest om??_lnx_managed_system*.gz file on the website:http://downloads.dell.com

   Note:

   At the time of writing this is the current Dell site, contact your Dell support contact if you cannot find the latest Dell OMSA software.
2. Install the software using the instructions provided by Dell.
3. Verify that the installation was successful by performing the following steps:
   • Verify that snmp daemon is up and running.

     % ps -ef | grep snmpd

   • Verify that the following commands execute without errors:

     % /usr/bin/omreport about

     % /usr/bin/omreport system version

4. Verify the Dell OMSA software is functioning correctly by verifying that the Dell OpenManage Server Administrator website is up and running.
   • Using your web browser, access the URL - https://target_hostname:1311.
   • Log in using an operating system account. Check that you are able to successfully log in and navigate in the website.
5. If the SNMP Community String for the SNMP daemon running on the Linux host is not public, set the SNMP Community String property in Enterprise Manager using the following steps:
   1. Log in into Enterprise Manager Cloud Control.
   2. Navigate to the home page of the specific host.
   3. From the Host menu, select Target Setup, then Monitoring Configuration.
   4. Set the SNMP Community String property to the correct value on this page.
6. Restart the Management Agent on the host.

   % login into host as the owner account of emagent software

   % emctl stop agent

   % emctl start agent

7. Note:

   The following step is not required if the Dell OMSA software was functional prior to the previous startup of the Management Agent.

   Verify that hardware monitoring is working correctly using the following steps:

   1. Log in to Enterprise Manager Cloud Control.

   2. Navigate to the home page of the specific host.

   3. From the Host menu, select Monitoring, then All Metrics.

   4. Verify that the following metrics are present on this page: Fans, Memory Devices, PCI Devices, Power Supplies, Processors, Remote Access Card, System BIOS, and Temperature.

   5. You can navigate to the metric data page by clicking on one of the metrics listed in the previous step and view the data that Enterprise Manager is able to fetch.
