Connecting an MRS Cluster to SNMP to Report Alarms

If users need to view alarms and monitoring data of a cluster on the O&M platform, you can use Simple Network Management Protocol (SNMP) on FusionInsight Manager to report related data to the network management system (NMS).

Prerequisites

The ECS corresponding to the server must be in the same VPC as the MRS cluster's Master node, and the Master node must be able to access the server's IP address and specified port.

Connecting an MRS Cluster to SNMP to Report Alarms

  1. Log in to the Manager and go to the SNMP configuration page.

    • MRS 3.x or later:
      1. Log in to FusionInsight Manager.
      2. Choose System > Interconnection > SNMP.
      3. Enable the SNMP service.
    • Versions earlier than MRS 3.x:
      1. Log in to MRS Manager and click System.
      2. In Configuration, enable Configure SNMP under Monitoring and Alarm.

  2. Set interconnection parameters based on Table 1.

    Table 1 Interconnection parameters

    Parameter

    Description

    Version

    Specifies the version of SNMP, which can be:

    • V2C: This is an earlier version with low security.
    • V3: This is a later version with higher security than SNMPv2c

    SNMPv3 is recommended.

    Local Port

    Specifies the local port. The default value is 20000. The value ranges from 1025 to 65535.

    Read Community Name

    Specifies the read-only community name. This parameter is available only when Version is set to V2C.

    Write Community Name

    Specifies the write community name. This parameter is available only when Version is set to V2C.

    Security Username

    Specifies the SNMP security username. This parameter is available only when Version is set to V3.

    Authentication Protocol

    Specifies the authentication protocol. This parameter is available only when Version is set to V3. SHA is recommended.

    Authentication Password

    Specifies the authentication password. This parameter is available only when Version is set to V3.

    Confirm Password

    Used to confirm the authentication password. This parameter is available only when Version is set to V3.

    Encryption Protocol

    Specifies the encryption protocol. This parameter is available only when Version is set to V3. AES256 is recommended.

    Encryption Password

    Specifies the encryption password. This parameter is available only when Version is set to V3.

    Confirm Password

    Used to confirm the encryption password. This parameter is available only when Version is set to V3.
    • The value of Security Username cannot contain repeated strings with the unit length as a common factor of 64 (such as 1, 2, 4, and 8), for example, abab and abcdabcd.
    • The Authentication Password and Encryption Password must contain 8 to 16 characters, including at least three types of the following characters: uppercase letters, lowercase letters, digits, and special characters. The two passwords must be different. The two passwords cannot be the same as the security username or the reverse of the security username.
    • For security purposes, periodically change the authentication password and encryption password when the SNMP protocol is used.
    • If SNMP v3 is used, a security user will be locked after five consecutive authentication failures within 5 minutes. The user will be automatically unlocked 5 minutes later.

  3. Click Create Trap Target in the Trap Target area. In the displayed dialog box, set the following parameters:

    • Target Symbol: specifies the trap target ID, which is the ID of the NMS or host that receives traps. The value consists of 1 to 255 characters, including letters or digits.
    • Target IP Address Mode (only for MRS 3.x or later): mode of the target IP address. The options are IPv4 and IPv6.
    • Target IP Address: specifies the target IP address, which can communicate with the management plane IP address of the management node.
    • Target Port: specifies the port receiving traps. The port number must be consistent with the peer end and ranges from 0 to 65535.
    • Trap Community Name: This parameter is available only when Version is set to V2C and is used to report the community name.

    Click OK.

    The Create Trap Target dialog box is closed.

  4. Click OK.
