Overview

This Overview page provides a dashboard view of data collection, processing, and delivery metrics across the DataStream deployment. Use it to monitor pipeline throughput, resource utilization, and performance at the Director, Cluster, or global level.

Accessing Stats

Navigate to Stats > Overview from the main navigation.

Filters

The page header provides two filter controls that affect all dashboard sections.

Time Range

Select a time period using the Presets tab or specify a custom range with the Date & Time Range tab.

Presets:

Preset	Period
Today	Current calendar day
This Week	Current calendar week
This Month	Current calendar month
Last 3 Months	Rolling 3-month window

Date & Time Range: Set a custom start and end date with time selection. The maximum allowed range is 3 months.

Entity Selection

Filter metrics by scope using the entity dropdown.

Option	Scope
All Directors	Aggregated metrics across all Directors and Clusters
Director name	Metrics for a single Director instance
Cluster name (Cluster)	Metrics for a specific Cluster

Page Header

The header displays three summary values for the selected entity and time period:

Metric	Description
Data Collected	Total raw data volume received from devices
Data Processed	Total data volume after pipeline processing
Data Sent to Targets	Total data volume delivered to target destinations

Data Overview

Three cards display data flow metrics from collection through delivery.

Collected Raw Data

Displays a pie chart of collected data volume broken down by device type. The card header shows total data size and event count for the selected period.

Click See All Devices to open a modal with a detailed table listing each device, its collected data volume, and event count.

Processed Data

Displays a grouped bar chart showing the top 5 pipelines processing the most data. Each pipeline shows Logs In and Logs Out volumes side by side, revealing the data reduction achieved by each pipeline. The card header shows total data size and event count.

Data Sent to Targets

Displays a gauge chart showing the distribution of processed data across target destinations, split between SIEM and other target types. The card header shows total data size and event count.

Data Collection and Transformation

Two cards provide operational health and performance metrics.

Director Stats

Displays the status of Directors, Agent Devices, and Stream Devices with enabled and disabled counts for each. When components have connection errors, a warning indicator appears with a Manage link to the relevant Directors management page.

When a single Director is selected, a Resource Utilization panel appears showing:

Metric	Description
CPU Utilization	Current CPU usage percentage
RAM Utilization	Current RAM usage percentage

Resource Utilization is only available for individual Director selection, not for All Directors or Cluster views.

When a Cluster is selected, the Director count label changes to the cluster name and displays member counts. Resource Utilization is not shown.

Pipeline Performance

Displays a line chart plotting latency, errors, and dropped logs over time for the selected period. The card header shows three summary values:

Metric	Description
Latency	Average pipeline processing latency in milliseconds, with a status tag
Pipeline Errors	Total error events during the selected period
Dropped Logs	Total dropped log events during the selected period

Latency status thresholds:

Tag	Range
Normal	0--20 ms
Higher	20--35 ms
Critical	35+ ms
