Amazon EBS integration
Amazon EBS provides highly durable, persistent block storage volumes for your EC2 instances. With Site24x7's Amazon EBS integration you can collect metrics to analyze volume workloads and tune up performance.
Setup and configuration
- If you haven't done it already, enable Site24x7 access to your AWS resources by creating Site24x7 as an IAM user or by creating a cross account IAM role. Learn more.
- Discovery and monitoring for your Elastic Block Store(EBS) volumes would begin automatically if you've enabled metric collection for your EC2 instances. This can be done by selecting the EC2 Instance in the Services to be discovered field. Learn more.
Polling frequency
Site24x7 polls the CloudWatch API as per the poll frequency set (1 minute to a day), to collect metrics for your block storage volumes. Learn more.
To view data
- Log in to your Site24x7 account and navigate to Cloud > AWS > EC2 Instance.
- From the list of monitored EC2 instances, choose an instance for which you want to view the metrics.
- Select the Volumes tab to view the graphed metrics.
Supported metrics
The following performance metrics are collected:
| Attribute | Description | Statistics | Data type |
|---|---|---|---|
| Volume IOPS Usage | Measures the utilization of I/O operations per second supported by the volume. | Average | Percent |
| Volume read bytes | Measures the total number of bytes read from the volume. | Sum | Bytes |
| Volume write bytes | Measures the total number of bytes written on the volume. | Sum | Bytes |
| Volume read ops | Measures the total number of read operations. | Sum | Count |
| Volume write ops | Measures the total number of write operations. | Sum | Count |
| Volume total read time | Measures the number of seconds spent on read operations | Average | Seconds |
| Volume total write time | Measures the total number of seconds spent on write operations | Average | Seconds |
| Volume idle time | Measures the total number of time in seconds when no read or write operations is performed | Average | Seconds |
| Volume queue length | Measures the total number of read write operations waiting to be completed | Average | Count |
| Volume throughput percentage | Measures the percentage of I/O operations performed per second in terms of the total IOPS provisioned. Only applicable for Provisioned IOPS SSD volumes only. | Average | Percent |
| Volume consumed read write ops | Measures the total amount of read write operations consumed in a period of time | Average | Count |
| Burst balance | Measures the percentage of I/O credits or throughput credits remaining in the burst bucket. Only applicable for General Purpose SSD (gp2), Throughput Optimized HDD (st1), and Cold HDD (sc1) volumes.AveragePercent | Average | Percent |
Note
Add a threshold profile to the block store volume attached to your instance. Learn more.
Supported volume metrics for Nitro-based instances
| Attribute | Description | Statistics | Data type |
|---|---|---|---|
| Volume Average Read Latency | The average time taken to complete read operations in a minute. | Average | Milliseconds |
| Volume Average Write Latency | The average time taken to complete write operations in a minute. | Average | Milliseconds |
| Volume IOPS Exceeded Check | Reports whether an application consistently attempted to drive IOPS that exceeds the volume's provisioned IOPS performance within the last minute. | Maximum | Count |
| Volume Throughput Exceeded Check | Reports whether an application consistently attempted to drive throughput that exceeds the volume's provisioned throughput performance within the last minute. | Maximum | Count |
| Volume Stalled IO Check | Reports whether a volume has passed or failed a stalled IO check at the last minute. This metric can be either 0 (passed) or 1 (failed). | Maximum | Count |
