Resolving Missed Runs on Linux Servers

Introduction

If you are experiencing missed runs on your Linux servers monitored by Virtana Service Observability, this troubleshooting guide will help you identify and resolve the issue. Timely execution of monitoring runs is critical to maintaining visibility and performance within hybrid and multi-cloud infrastructure environments.

Issue Description

Missed runs on Linux servers occur when the scheduled monitoring or data collection jobs do not execute at their expected times, potentially leading to gaps in observability and delayed incident detection.

Signs of Missed Runs

• No recent data or updates from specific Linux server devices in the Virtana Service Observability interface.
• Authentication errors or connection failures reported for certain collectors or IP addresses.
• Alerts or logs indicating failed or skipped monitoring runs.

Basic Troubleshooting Steps

Follow these steps to resolve missed runs on Linux servers within Virtana Service Observability:

1. Restart the zencommand service on the affected collectors to refresh connections and clear transient errors.
2. Check the Virtana Service Observability interface or collection debug logs for devices reporting authentication or connection errors.
3. Investigate the connection issues on the specific IP addresses identified; this may include network connectivity, firewall settings, or credential problems.

Advanced Troubleshooting

If basic steps do not resolve the issue, consider the following advanced actions:

1. Review collector and zencommand logs for detailed error messages or patterns related to missed runs.
2. Validate the collector's system resources and ensure there is no overload or resource contention causing service failures.
3. Confirm network connectivity and permissions from collectors to the monitored Linux servers.
