Logger Troubleshooting for Power Users

Summary:

The document "Logger Troubleshooting for Power Users" by David Bush, a Senior Logger Support Engineer at HP, is a comprehensive guide aimed at helping users address common issues with Logger software used in server and web application environments. Here's a summary of the key points from each section of the report: 1. Understanding Logger Architecture: The document introduces the architecture of a logger system, which includes components such as Server, Receiver, Processor, Connector, Report Engine, Web Server, and Aps for data collection, processing, and reporting across various platforms. 2. Common Logger Problems: The text identifies multiple issues that can arise in a logger system including performance issues (slow speed), reporting issues (empty or not arriving reports), search issues (unexpected results or slow performance), configuration issues, upgrade issues, hardware issues, among others. 3. Symptoms of Trouble: It is crucial to identify the onset, changes made before the issue began, expected behavior, whether it affects multiple users or devices, and if reproducible. 4. Performance Issues: This includes slow performance in UI speed, search scan rates, CPU load, index lag, and storage group size. Quantifying these aspects can help pinpoint issues. 5. Reporting Issues: Possible problems include empty reports due to query mismatches or incorrect scanning limits, non-publication of reports, conflicts in schedules, and expensive queries timing out. 6. Search Issues: This involves unexpected search results or slow performance, including how quickly events are scanned and exported, and potential timeouts during the process. 7. Determine Baseline Scan Rate: A method to check what a Logger's capacity is by running specific searches and checking scan rates in controlled conditions. 8. Forwarding & Receiving: Issues here relate to data forwarding or receiving, including filtering based on time, unified queries, indexing with regular expressions, caching, and network configuration. 9. Configuration Issues: These involve authentication issues, remote file system configurations, and SAN setups that can affect logger functionality. 10. Upgrades: It is important to follow upgrade paths carefully by reading release notes, validating upgrade files, backing up configurations, and ensuring iLo settings are managed during upgrades. 11. Hardware Issues: This includes checking the status of RAID systems, capturing screenshots for visual inspection, and addressing issues with iLo (Integrated Lights Out) that could affect logger operation. 12. Contact Logger Support: Guidelines on how to effectively communicate the issue include providing detailed information about symptoms, frequency, environment setup, software version, platform type, and whether a remote session is needed. 13. Recovery and Backup: The document emphasizes the importance of regular configuration backups and event archives (data) for disaster recovery scenarios, as well as using tools like iPackager to manage reports. This guide serves as an essential reference manual for users facing issues with their Logger software, providing a step-by-step approach to diagnosing and resolving problems at both system and hardware levels.
