What is Endpoint Diagnostics?
Endpoint diagnostics is the collection and interpretation of device evidence to investigate an IT problem. Processes, memory use, disk space, event logs, services, network configuration, installed software, and security settings can help explain a symptom. Checks may be manual or automated. A useful diagnosis connects the observations to the original question and separates confirmed findings from possible causes.
Put the support workflow into practice.
Support users, investigate issues, and take action in one modern IT support platform.
Diagnostic checklist
Start with the symptom, then collect the evidence.
Record which device and application are affected, when the problem occurs, and what changed. Collect the checks relevant to that question before restarting services or changing settings.

How Endpoint Diagnostics Works
Define the question
Identify the endpoint, affected task, timing, and user impact. A slow application launch calls for different checks from a VPN authentication failure.
Collect endpoint diagnostics
Use operating-system tools or a connected management agent. On Windows, Task Manager and Event Viewer provide process and event context; macOS offers Activity Monitor and Console; Linux offers process tools and system logs. Record the collection time and relevant output.
Compare observations
Check whether the findings line up with the symptom and its timing. Compare with available historical readings or unaffected devices, labeling those sources separately. A recent update or high resource reading is a lead to test, not proof of the cause.
Record the conclusion and next step
Explain what the evidence supports, what remains unknown, and which further check or action is justified. Obtain any required authorization before a change, then verify the affected task after remediation.
Benefits of Endpoint Diagnostics

Which diagnostic checks should you collect?
| Dimension | Evidence to collect | How to interpret it |
|---|---|---|
| CPU and memory | Process readings, system load, memory pressure, and sampling time. | Repeat readings during the symptom. A busy process may be doing expected work; usage alone does not prove a fault. |
| Disk | Free space, relevant disk errors, and available I/O readings. | Separate capacity pressure from an I/O bottleneck. Record which volume and application are affected. |
| Services and logs | Service state and events from the affected time window. | Check whether an error recurs with the symptom. Preserve the output before restarting anything. |
| Network and VPN | Interface state, DNS results, routes, and relevant client logs. | Distinguish local configuration from gateway, identity, or upstream issues; record checks that could not run. |
| Recent changes | Update history, installed versions, and available baseline readings. | Use timing to form a hypothesis. Compare with a working device or another observation before assigning a cause. |
How GenticFlow Uses Endpoint Diagnostics
GenticFlow Investigations uses read-only diagnostics on connected Windows, macOS, and Linux endpoints. A technician can start with a question, review the plan, follow the checks, and read or export the findings. Fleet Investigations adds a combined view across selected endpoints. Available historical context is kept distinct from live evidence, and any follow-up remediation uses separate actions subject to the applicable permissions and policies.
Try it on your daily support work.
Try the full product for 30 days with real support requests and endpoints. Investigate the issue, choose the next action, and keep the findings with the case if more work is needed.

Frequently Asked Questions
How does endpoint diagnostics support AI resolution?
Diagnostics provides evidence for deciding what to do next. GenticFlow Investigations is read-only; its findings can inform a separate permitted action or support workflow. A completed investigation does not mean the problem was repaired. Verify the outcome after any change.
Does endpoint diagnostics require installing software?
Local checks can use tools already included with the operating system. GenticFlow's live remote diagnostics requires its connected endpoint agent, deployed through your existing software distribution process or a manual installation. Check supported operating systems and permissions before deployment.
What should an endpoint investigation report contain?
Include the original question, device and scope, collection times, checks and output, findings with supporting evidence, possible causes, missing or failed checks, and recommended next steps. Label historical data clearly. If a fix was performed separately, record its authorization and verification result rather than assuming the diagnostic conclusion proves recovery.
How should I compare endpoint diagnostics tools?
Try a representative issue. Check operating-system support, required access, how fresh the evidence is, whether raw output and failed checks remain visible, and whether findings can be reviewed or exported. For fleet work, check which devices were actually examined. Evaluate follow-up action controls separately from diagnostic capability.
Can remote diagnostics work when a device is offline?
Fresh checks require connectivity. Saved inventory and previous findings may help plan the investigation, but cannot confirm current device health. Reconnect the endpoint and collect the missing evidence before relying on a live diagnosis.
