Prometheus Agent View
Prometheus Agent is a lightweight version of Prometheus Server. It scrapes the metrics for all hosts and components. The metrics are then reported to and stored on AOM or a third-party monitoring platform. The Prometheus Agent view displays some built-in metrics provided by Prometheus, which can be used to monitor and measure system performance and status.
Metric Description
You can view Prometheus Agent metrics in the following table.
| Metric | Unit | Description |

| Remote Write Rate | byte/s | The number of bytes remotely written per second. |
| Average Remote Write Duration | second | Average time consumed by remote writes. |
| Bytes Pending for Remote Write | byte | The number of pending bytes during a remote write. |
| Packets Discarded for Remote Write per Second | N/A | The number of packets discarded per second during a remote write. |
| Failed Remote Write Requests per Second | N/A | The number of failed remote write requests per second. |
| Percentage of Failed Remote Write Requests | % | Percentage of failed remote write requests. |

| Failed Writes During Collection per Second | N/A | The number of write errors during scrapes per second. |
| Collections with Size Exceeding the Threshold per Second | N/A | Collections with size exceeding the threshold per second. |
| Read Rate of Sending Queue | byte/s | The number of bytes read by a sending queue per second. |
| Write Rate of Sending Queue | byte/s | The number of bytes written to a sending queue per second. |
| Pending Size of Sending Queue | byte | The number of bytes suspended in a sending queue. |
| Blocks Read per Second | N/A | The number of blocks read by a sending queue per second. |
| Blocks Written per Second | N/A | The number of blocks written to a sending queue per second. |
| Discarded Blocks per Second | N/A | The number of dropped blocks in a sending queue per second. |
