# Graphs

The **Graphs** tab visualizations deliver immediate insight into the performance of your job over a given period of time, enabling you to discover delays, the number of events that were handled, and how the cluster has been utilized.  

### Delay

The Delay chart visually displays delays in **write to storage**, **read from source**, and **parse data** for your job. Depending on the job type, you may see only one of these options:

### Handled Events

The Handled Events chart displays **write to storage**, **read from source**, and **parse data** over the time period selected in the date picker:&#x20;

### Cluster Utilization

The CPU utilization of the cluster. The chart visualizes how much of the server's processing capacity is currently in use, and includes the current job:

### Customize the view

ou can use the **Today** button to set the time span of this view. Choose the pre-set options, such as **Last 30 minutes**, or **Last 12 hours** to set the view, or use the calendar to select the start date and time, and the end date and time. &#x20;

Then, you can hover your mouse over a point in time on any of the charts to display the pop-up that shows the metrics for the selected point in time:&#x20;

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://upsolver.gitbook.io/content/reference-1/monitoring/job-status/stream-and-file-sources/graphs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
