Monitoring and Alarm

A New Feature: SNMP Management

SNMP is the simple network management protocol used to manage devices in the network. ZStack Cloud 4.7.21 uses this protocol to realize a connection between the Cloud and a 3rd-party platform, thus allowing the 3rd-party platform to proactively get resource monitoring data from the Cloud or passively receive alarms pushed from the Cloud.

Currently, protocols of the v2c and v3 types are supported.

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

Supports Visual Configuration of SNMP Parameters

ZStack Cloud 4.7.21 allows you to configure SNMP parameters in a visual method on the UI page, including the SNMP agent port, protocol type, user name, user authentication, and data encryption. These parameters is used for the quick establishment of a connection between the 3rd-party platform and the Cloud.

Allows 3rd-Party Platform to Monitor Resources on Cloud

After being integrated with ZStack Cloud through SNMP, a 3rd-party platform can proactively get resource monitoring data with OID instructions from the Cloud. ZStack Cloud provides a specific MIB file containing OIDs for you to download.

Currently, you can get the monitoring data of each host on ZStack Cloud through the 3rd-party platform.

Allows Cloud to Push Alarms to 3rd-Party Platform

Starting from ZStack Cloud 4.7.21, you can add a 3rd-party platform as an SNMP Trap receiver. This receiver can be used as an endpoint and attached to specified alarms. Then, the Cloud can proactively push messages to the 3rd-party platform when the alarms are triggered. The 3rd-party platform can parse alarms received according to the MIB file.

Optimization of Disk and NIC Monitoring Charts

ZStack Cloud 4.7.21 splits the disk and NIC monitoring charts on the resource details page, enabling you to view multiple disk/NIC monitoring data on the same page. This optimization covers the monitoring chart on details page of the following resources: VM instance (external monitoring), VPC vRouter (external monitoring), host, and backup storage.

Splits Disk Monitoring Chart
ZStack Cloud splits the disk monitoring chart into two charts: Disk Speed chart and Disk IOPS chart. Both charts can display two metrics (read and write) at the same time. Therefore, you can conveniently master more disk monitoring data through the same page.

Splits NIC Monitoring Chart
ZStack Cloud splits the NIC monitoring chart into three charts: NIC Data Transfer Rate, NIC Packet Rate, and NIC Packet Discard Rate chart. Each chart can display two metrics (out and in) at the same time. Therefore, you can conveniently master more NIC monitoring data through the same page.

A Stronger Risk Prompt when Dual Management node Database Needs Synchronization

Starting from ZStack Cloud 4.7.21, when an asynchronization is detected between the dual management node database, the Database Status on the Management Node Monitoring page is displayed as error and marked in red. Meanwhile, a global risk banner appears to remind you to sync the database as soon as possible to avoid data loss.
