Hello, everyone!
This post will share with you the cloud eye service.
What is Cloud Eye(CES)?
Cloud Eye (CES) is an open platform that monitors resources, generates alarms, and sends notifications of resource changes. CES can monitor metrics of the following services: Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Virtual Private Cloud (VPC), Relational Database Service (RDS), Elastic Load Balance (ELB), Auto Scaling (AS), Web Application Firewall (WAF), and Host Vulnerability Detection (HVD). You can add alarm rules and configure alarm notification policies to learn the running status and performance of service instances in a timely manner.
Table 1 CES functions describe the functions provided by CES.
NOTE:
On the Monitoring Overview page, if there is no data for Monitored Instance Statistics, the system displays No data available. Check whether there are instances in the system or whether other services are properly interconnected with CES. It indicates that CES does not receive monitoring data reported by other services. The possible causes are as follows: Monitoring data is not generated because tenants do not create tenant ECSs or do not mount EVS disks; other services (such as Ceilometer and AS) are not properly interconnected with CES. For details, see Interconnecting Ceilometer with CES.

Function | Description |
Dashboard | Displays the number of metrics of each service monitored by CES. You can add or delete metrics. The service metrics to choose from are as follows: ECS: CPU Usage, Disks Read Rate, Disks Read Requests, Disk Usage, Disks Write Rate, Disks Write Requests, Memory Usage, Inband Incoming Rate, Inband Outgoing Rate, Outband Incoming Rate, and Outband Outgoing Rate EVS: Disks Read Rate, Disks Write Rate, Disks Read Requests, and Disks Write RequestsAS: CPU Usage, Memory Usage, Instance Qty., Inbound Rate, and Outbound Rate ELB: CPS, Active Connections, New cps, Inbound Packets, Inbound Rate, Outbound Rate, Abnormal Hosts, and Normal Hosts. RDS: Disk Usage, CPU Usage, Memory Usage, Input/output operations per second (IOPS), Network Input Throughput, Network Output Throughput, Total Connections, Active Connections, Query Per Second (QPS), transactions per second (TPS), Buffer Pool Usage, Buffer Pool Hit Rate, Buffer Pool Dirty Block Rate, InnoDB Read Throughput, InnoDB Write Throughput, InnoDB File Read Frequency, InnoDB File Write Frequency, InnoDB Log Write Request Frequency, InnoDB Log Physical Write Frequency, InnoDB Log fsync() Write Frequency, Temporary Tables Qty, Key Buffer Usage, Key Buffer Write Hit Rate, Key Buffer Read Hit Rate, MyISAM Disk Write Speed, MyISAM Disk Read Speed, MyISAM Buffer Pool Write Speed, MyISAM Buffer Pool Read Speed, Delete Execute Speed, Insert Execute Speed, Insert_Select Execute Speed, Replace Execute Speed, Replace_Select Execute Speed, Select Execute Speed, Update Execute Speed, Row Delete Speed, Row Insert Speed, Row Read Speed, Row Update Speed, Total Disk Size, Disk Usage, Disk Read Throughput, Disk Write Throughput, Average Time Read per Disk, Average Time Write per Disk, Average Disk Queue Length, and Number of Database Connections in Use WAF: SQL Injection Alarms, cross site script (XSS) Vulnerability, Alarms, Webshell Upload Alarms, Link Theft Alarms, IP Address Blacklist Alarms, and IP Address Whitelist Alarms HVD: High-Risk Vulnerabilities, Medium-Risk Vulnerabilities, and Low-Risk Vulnerabilities |
Instance monitoring | Shows the status of service instances. If you have signed for one or more of the following services: ECS, EVS, VPC, ELB, AS, WAF, HVD, and RDS, you can use CES to view the status of service instances without installing additional plug-ins. |
Alarm | Adds, views, modifies, deletes, enables, or disables alarm rules. |
CES provides the following functions:
· Automatic monitoring: Monitoring starts automatically after ECSs or AS groups are created. No manual intervention or additional plug-ins is required.
After obtaining resources, you can view instance monitoring data on the Instance Monitoring page of the CES console in 5 to 10 minutes, during which the system is trying to obtain and aggregate data.
· Flexible alarm configuration: You can configure alarm rules and thresholds for specific metrics. You can also disable or enable alarm rules as required.
When you add alarm rules, you can choose to monitor one metric for multiple instances (if multiple instances contain the same metric), achieving the goal of adding monitoring objects in batches.
Parameter values configured in an alarm rule can be modified at any time. The new parameter values take effect from the next monitoring interval.
If a monitored object is not used, you can disable the alarm rule configured for the object. If the object is used again, you can then enable the alarm rule.
If the monitored object is not used any longer or has been deleted, you can manually delete the alarm rule configured for the object.
· Monitoring panel: On the Dashboard page, you can follow metrics. This function allows you to view detailed monitoring information of followed service instances displayed in charts. You can also stop following metrics by deleting the charts. CES dashboard supports multi-metric comparison.
· Alarm history: After enabling Cloud Trace Service (CTS), you can view alarms generated in the last seven days.
Application Scenarios
· Routine Management
CES monitors many metrics, including CPUs, disk I/O, and network traffic, to ensure the reliability of your services.
· Alarm Notification
If an alarm is generated, the available data is insufficient for requirements, or an alarm is cleared, CES notifies you by email, text message, or by sending HTTP/HTTPS requests to the server IP addresses.
· Capacity Adjustment
After configuring alarm rules for resource-related metrics, you can understand the instance running status in a timely manner, and scale up resources if receiving notifications indicating resource insufficiency.
After Auto Scaling (AS) is interconnected with CES and alarm rules are set for resources, CES sends an alarm to AS when an alarm is triggered. AS adjusts the capacity according to the alarm information。
That's all, thanks!
