SNMP Management

What is SNMP Management

SNMP Management: SNMP Management is a service that allows a 3rd-party platform to monitor resources and events on ZStack Cloud, as well as receive alarms from ZStack Cloud.

Concept

The following are concepts involved in SNMP Management

SNMP: SNMP stands for Simple Network Management Protocol, a protocol used to manage the devices in the network. In SNMP Management, it is through this protocol that the 3rd-party platform obtains the monitoring data of ZStack Cloud resources and receives alarms from ZStack Cloud.
NMS: NMS stands for Network Management System, a system that monitors and manages the devices in the network through SNMP. NMS sends requests to the agent of managed devices to query the device parameters, and receives the trap messages sent from the agent. In SNMP Management, NMS refers to a 3rd-party platform.
SNMP Agent: The agent of the managed objects. This agent is responsible for response to the requests from the NMS and send Trap message to the trap receivers proactively. In SNMP management, the management nodes of ZStack Cloud undertakes the role of SNMP agent.
Managed Object: In SNMP Management, Managed Object refers to resources on ZStack Cloud.
MIB: MIB is a database that is maintained by the SNMP Agent and defines the properties of managed objects, such as the object name, state, access permission, and object data type. A 3rd-party platform uses the MIB as a reference to collect the monitoring data ZStack Cloud resources and parse the alarms received. ZStack Cloud provides its dedicated MIB for you to download and refer to.
SNMP Trap Receiver: SNMP trap receiver is a 3rd-party server used to receive alarms pushed by Cloud. You can add an SNMP trap receiver as an endpoint and attached to alarms, so that Cloud can push specified alarm messages to this SNMP trap receiver.

Enable SNMP Service

On the main menu of ZStack Cloud, click Settings > Platform Setting > SNMP Management. On the SNMP Management page, click Enable. Then, the Enable SNMP Management page is displayed.

Set the following parameters on the displayed page:

SNMP Agent Port: Set an SNMP agent port to receive and response to the request from the 3rd-pafrty platform.
Note: SNMP SNMP Agent port is a port on the management node. Default: 1161. Valid values: 1024-65565.
Protocol Version: Select a SNMP version. Supported two protocol version: v2c and v3.
- If you choose v2c, set the following parameters:
  - Community: Set a community. This community is used for the connectivity authentication between ZStack Cloud and the 3rd-party platform.
- If you choose v3v, set the following parameters:
  - Username: Set the username.
  - User Authentication: Optional. If set to true, a security authentication is enabled for the connectivity between ZStack Cloud and the 3rd-party platform and you need to set the following parameters:
    - Authentication Protocol: Select an authentication protocol. Supported protocols: MD5, SHA, SHA224, SHA256, SHA384, and SHA512.
    - Authentication Password: Set an authentication password.
    - Confirm Password: Enter the password again to confirm it.
  - Data Encryption: Optional. Choose whether to encrypt the data transmitted between ZStack Cloud and the 3rd-party platform. To enable Data Encryption, you need to enable User Authentication first and set the following parameters:
    - Encryption Protocol: Choose an encryption protocol. Supported protocols: DES,AES128, AES192, AES256, and 3DES.
    - Encryption Password: Set an encryption password.
    - Confirm Password: Enter the password again to confirm it.
SNMP Trap Receiver: Optional. Enter the IP address and port of a 3rd-party server which is used to received alarms sent from ZStack Cloud.

Manage SNMP Service

On the main menu of ZStack Cloud, choose Settings > System Setting > SNMP Management. Then, the SNMP Management page is displayed.

The following lists the actions you can perform on the SNMP Management page:

Action	Description
Enable SNMP Management	Enable the SNMP management.
Modify SNMP Config	Modify the SNMP protocol configurations, such as the SNMP agent port, protocol version, community, and username.
Add SNMP Trap Receiver	Add a new SNMP trap receiver. An SNMP trap receiver can be added as an endpoint and attached to alarms, so as ZStack Cloud can push specified alarm messages to the SNMP trap receiver.
Edit SNMP Trap Receiver	Modify the IP address and port of the SNMP trap receiver.
Delete SNMP Trap Receiver	Delete an SNMP trap receiver. Note: If the SNMP trap receiver has been added as an alarm endpoint, this alarm endpoint will be deleted synchronously.
Download MIB	Download the MIB file provided by ZStack Cloud. The 3rd-party platform relies on this file to collect the data of ZStack Cloud resources and parse alarms from ZStack Cloud.
Disable SNMP Management	Disable the SNMP management. After the enabling, the 3rd-party platform will no longer collect resource data from ZStack Cloud proactively. However, the SNMP trap receivers added as alarm endpoints can continue received alarms sent from ZStack Cloud. ZStack Cloud will keeps the SNMP parameters you set so as you can re-enable the SNMP service conveniently on the next time.
