Monitoring Exadata Database Machine Components

Enterprise Manager collects details for the following components:

Exadata Storage Servers

An Enterprise Manager Agent could collect Exadata Storage Server metrics through cellcli calls via ssh, ExaCLI or RESTful API. SNMP traps are sent to the Enterprise Manager Agent for subscribed alert conditions.

Monitoring with cellcli requires SSH equivalence to be set up between the agent user and the Exadata Storage Server monitor user on each Exadata Storage Server.

On the home page, rich storage data is collected, including:

  • Aggregate storage metrics.

  • Exadata Storage Server alerts via SNMP (PUSH).

  • Capacities.

  • Database-level metrics.

Cisco/RoCE Switch (Systems Infrastructure Switch)

An Enterprise Manager Agent runs a remote SNMP get call to collect metric data for the Cisco/RoCE switch, including details on:

  • Status / Availability

  • Port status

  • Vital signs: CPU, Memory, Power, Temperature

  • Network interface various data

    • Incoming traffic errors, traffic kb/s and %

    • Outgoing traffic errors, traffic kb/s and %

    • Administration and Operational bandwidth Mb/s

ILOM Targets (Systems Infrastructure Server)

An Enterprise Manager Agent runs remote SSH calls to each SI server target.

The following details are collected:

  • Response – availability

  • Sensor alerts

    • Temperature

    • Voltage

    • Fan speeds

    • Configuration Data: Firmware version, serial number, and so forth.

Monitoring Systems Infrastructure ILOM Server Target Using Non-root User

Follow these steps to create the non-root user for monitoring the ILOM server target:

  1. Login to the ILOM server from the browser console.

  2. Go to ILOM Administration. In the left side panel, click User Management.

  3. In the Users section, click Add User. The Add User dialog box is displayed.

  4. In the Add User dialog box, create the new ILOM non-root user. Provide user name, password, and enable the role permissions Console (c) and Read Only (o).

  5. Save this new user and verify the user details.

Note:

When the non-root user is used, create the SNMPv3 user / SNMP v2 community string and SNMP subscription on the server manually to receive the SNMP traps.

Power Distribution Units (PDUs)

An Enterprise Manager Agent runs remote SNMP get calls and receives SNMP traps (PUSH) from each PDU. Collected details include:

  • Response and ping status.

  • Phase values.

InfiniBand Switch (Systems Infrastructure Switch)

An Enterprise Manager Agent runs remote SSH calls to the InfiniBand switch to collect metrics. The InfiniBand Switch sends SNMP traps (PUSH) for all alerts.

Monitoring requires ssh equivalence for the root or ilom-admin user for metric collections such as:

  • Response

  • Various sensor status

    • Fan

    • Voltage

    • Temperature

  • Port performance data

  • Port administration
