How to Analyze Scheduled Job Logs in ServiceNow: Troubleshooting and Best Practices

Scheduled jobs in ServiceNow automate critical tasks, ensuring efficiency and consistency. Monitoring and troubleshooting their execution is vital to detect errors early and maintain operational reliability. This article guides ServiceNow administrators and developers in finding logs for scheduled jobs, troubleshooting common issues, and implementing best practices.

Understanding Scheduled Jobs in ServiceNow

Scheduled jobs (Scheduled Script Executions) automate routine tasks such as data exports, system maintenance, and integrations. They run scripts at specified intervals or times without user intervention.

Common Causes of Scheduled Job Failures

• Script errors or exceptions

• Network connectivity issues

• Incorrect FTP credentials or configurations

• Misconfigured or inactive schedules

• No available data for transfer

  
  

Step-by-Step Troubleshooting Guide

1. Checking System Logs

Navigate to System Logs > All to identify any script-generated log messages.

2. Filtering for Script Logging

Use filters to narrow down relevant logs by job name or specific script-generated messages.

3. Manual Testing in Scripts – Background

Manually execute the script via Scripts – Background to observe immediate results and identify errors.

4. Verifying Scheduled Jobs in System Scheduler

Check the scheduled job configurations through System Scheduler > Scheduled Jobs > Scheduled Jobs to confirm scheduling details and activation status.

5. Reviewing the sys_trigger Table

Inspect the sys_trigger table to verify job execution history, next scheduled run, and recent activity.

(The sys_trigger table only stores jobs that are scheduled to run in the future or are currently executing, and records of completed jobs are immediately removed.)

6. Analyzing the syslog_transaction Table

Examine the syslog_transaction table (System Logs > Transactions) to confirm if the scheduled job executed as expected and to review transaction details.

(However, not all scheduled jobs are recorded in syslog_transaction, so it is necessary to also check System Logs > All for a complete execution history.)

Alternative Solutions and Best Practices

• Utilize Scheduled Data Exports or Export Sets for improved tracking and reduced custom scripting.

• Implement comprehensive logging within scripts (gs.info, gs.warn, gs.error).

• Consider using Flow Designer and IntegrationHub for modern, reliable scheduling and integrations.
