1 Introduction

1.1 What Is Cloud Eye?Cloud Eye (CES) is an open monitoring platform that provides monitoring, alarm reporting,and alarm notification for your resources near real time. CES monitors metrics of ElasticCloud Server (ECS), Elastic Volume Service (EVS), Virtual Private Cloud (VPC), ElasticLoad Balance (ELB), Auto Scaling (AS), and Relational Database Service (RDS). You canadd alarm rules and configure alarm notification policies to learn the running status andperformance of the monitored objects in a timely manner.

Table 1-1 describes the functions provided by CES.

Instancemonitoring

Shows the status of service instances. If you have signed up for one ormore of the following services: ECS, EVS, VPC, ELB, AS, and RDS,you can use CES to view the status of service instances withoutinstalling additional plug-ins.

Alarm Adds, views, modifies, deletes, enables, or disables alarm rules.

1.2 FunctionsCES provides the following functions:


Issue 05 (2016-12-30) 2

l Automatic monitoring: Monitoring starts automatically after ECSs or scaling groups arecreated. No human intervention or additional plug-ins is required.

After you have obtained resources, you can view monitoring data of instances inInstance Monitoring on the CES console in 5 to 10 minutes, which are required for dataobtaining and rollup.

l Flexible alarm configuration: You can configure alarm rules and thresholds for specificmetrics. You can also disable or enable alarm rules as required.

– When you add an alarm rule, you can select multiple monitored objects for a singlemetric.

– Parameter values configured in an alarm rule can be modified at any time. The newparameter values take effect from the next monitoring interval.

– If the monitored object is not used, you can disable the alarm rule configured for theobject. 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 canmanually delete the alarm rule configured for the object.

l Real-time notification: You can enable the alarm notification function to receivenotification short messages and emails, or enable CES to send messages to the server.

– If an alarm is generated, the available data is insufficient for requirements, or analarm is cleared, CES sends notifications to your registered mobile phone or emailbox.

– CES sends only one notification for an alarm even if the alarm is active for a longperiod of time.

l Following Metrics: On the Dashboard page, you can follow metrics. This allows you toview detailed monitoring statistics displayed in charts. You can also stop followingmetrics by deleting them.

l Historical alarms: You can enable the alarm notification function and view historicalalarms in the notification emails or short messages.

1.3 Application Scenarios

Routine Management

CES provides all-around monitoring for your resources, including CPUs, disk I/O, andnetwork traffic, ensuring end-to-end delivery of your services.

Problem Notification

If an alarm is generated, the available data is insufficient for requirements, or an alarm iscleared, CES sends notifications to your registered mobile phone or email box.

Capacity Adjustment

After you configure alarm rules for resource-related metrics, you can obtain information aboutthe running status of monitored objects in a timely manner, and scale up resources if receivingnotifications indicating resource insufficiency.


Issue 05 (2016-12-30) 3

1.4 Related Servicesl CES generates alarms that can trigger scaling actions implemented by the AS service.

– The alarm rules configured during AS group creation are synchronized to the CESservice. Then, the CES service generates alarms and sends the alarms to AS forimplementing scaling actions.

– You can create monitoring tasks for metrics of ECS instances providing similarfunctions to enable centralized monitoring of and alarm reporting for the instances.

l You can directly switch to the CES console from the ECS console to view monitoredinformation about specific ECSs.– If an ECS instance stops, becomes faulty, or is deleted, the monitoring data of this

instance cannot be queried on the CES console. If the instance is started again orrecovers, you can view the monitoring data of it again.

– Twenty-four hours after an instance stops or becomes faulty, the CES considers thatthe instance does not exist and no longer monitors the instance. You need tomanually delete the alarm rules configured for the instance.

l CES monitors the resources of ECS, EVS, VPC, ELB, AS, and RDS. Table 1-2, Table1-3, Table 1-4, Table 1-5, Table 1-6 and Table 1-7 and Table 1-7 list the monitoringmetrics of different services.

4.4 What Alarm Status Does CES Support?CES supports three alarm status: Alarm, OK, and Insufficient data.


Issue 05 (2016-12-30) 30

l If an alarm rule is disabled, its alarm status is considered as invalid, and two dashes (--)are displayed.

l Insufficient data is typically caused by ECS stopping or deletion.

4.5 What Is an Alarm Notification? How Many Types ofAlarm Notifications Exist? How Can I Configure Them?

Alarm notifications are actions that the system takes when the alarm status of an alarm rule ischanged. You can configure alarm notifications when creating or modifying an alarm rule.You can also disable alarm notifications.

CES supports the following two alarm notification types:

l Sends notification emails or short messages to users.l Triggers automatic capacity expansion and reduction by interworking with the AS

service.

4.6 How to Add Customized Monitoring Metrics?

On the Dashboard page, click in the My Metrics area. On the Add MonitoringMetric page, select the followed metrics as prompted.

4.7 Why Are the Network Traffic Metrics in CES Differentfrom Those in ECS Detected by the Tool?

The sample data collection interval in the CES is different from that used by the metricmonitoring tool in the ECS.

The CES collects ECS and EVS data at a 4-minute interval. However, the metric monitoringtool in the ECS collects the data at a 1-second interval.

A longer data collection interval causes distortion of data generated during a short period oftime. Therefore, CES is suitable for long-term website monitoring and monitoring ofapplications running on ECSs.

Furthermore, you can configure alarm thresholds so that alarms can be generated in the eventof resource exceptions or insufficiency, improving resource reliability.

4.8 What Is Rollup?Rollup is the process by which CES calculates the average, maximum, minimum, andvariance values based on sample raw data collected in different periods. The calculationperiod is called a rollup period.

Rollup is a smooth calculation process. The longer the rollup interval, the more smoothlyprocessing will be implemented, and the more accurate the generated data for trend predictionand statistics will be. The shorter the rollup interval is, the more accurate the generated datafor alarm reporting will be.


Issue 05 (2016-12-30) 31

The rollup period can be 5 minutes, 20 minutes, 1 hour, 4 hours, and 1 day.

The methods CES uses to process collected data vary depending on the data type:

l If the data is an integer, the data will be rounded.l If the data is a decimal fraction, two decimal places will be retained. Any further decimal

places will be rounded.

For example, the instance quantity in AS is an integer. If the rollup interval is 5 minutes, andthe values of the collected metrics data are 1 and 4, respectively, the average value is[(1+4)/2] = 2, rather than 2.5.

You can choose the CES mode based on the characteristics of the rollup to meet your servicerequirements.

4.9 How Long Is Metric Data Retained?Metric data includes original metric data and rollup metric data.

l Original metric data is sample raw data and is generally retained for two days.l Rollup metric data is data aggregated based on original metric data. The retention

durations for rollup metric data vary depending on the rollup period.– Metric data whose rollup period is 5 minutes is retained for 10 days.– Metric data whose rollup period is 20 minutes is retained for 20 days.– Metric data whose rollup period is 1 hour is retained for 155 days.– Metric data whose rollup period is 4 hours is retained for 300 days.– Metric data whose rollup period is 1 day is retained for 5 years.

If a resource instance is stopped, closed, or deleted, an original metric will be deleted onehour after its original data is not reported for one hour. After the metric data report resumes,the historical data of the metric is available.

4.10 What Are the Effects on ECS Monitoring Metrics IfOTC Tools Is Not Installed on ECSs?

If OTC tools is not installed on ECSs, CES can monitor the outband incoming rate andoutband outgoing rate. However, it cannot monitor the memory usage, disk usage, inbandincoming rate, and inband outgoing rate metrics, which reduces data accuracy of CPU usage.

For details about ECS monitoring metrics supported by CES, see ECS monitoring metrics.

4.11 How Can I Export Monitoring Data?On the CES dashboard page, choose Instance Monitoring and click Export MonitoringData. Select Service, Monitored Object, and Metric as prompted. Click Export.

l The first row of the report indicates the metric collection time expressed in Unixtimestamp, and the second row indicates the metric data.

l If you need to convert the time in Unix timestamp to the time of the target time zone,perform the following steps:


Issue 05 (2016-12-30) 32

https://docs.otc.t-systems.com/api/ecs/en-us_topic_0022067719.html

a. Use Excel to open a .csv file.b. Use the following formula to convert the time:

Target time = (Unix timestamp/1000 + (target time zone)*3600)/86400 + 70*365+ 19

c. Set the cell format to Date.For example, the Unix timestamp is 1475918112000 and the target time is Beijingtime. Beijing is located in the UTC+8 time zone. Therefore, the target time =(1475918112000/1000 + (+8)*3600)/86400 + 70*365 + 19. Set the cell format todate and select such format as 2016/3/14 13:30. Then, the final time is obtained,that is 2016/10/8 17:15.

4.12 How Many Rollup Methods Does CES Support?CES supports the following four rollup methods:

l AverageAverage value of metric data within a rollup period

l MaximumMaximum value of metric data within a rollup period

l MinimumMinimum value of metric data within a rollup period

l VarianceDeviation value of metric data within a rollup period
