Log Management and Analytics - Powered by Grail

OneAgent automatically detects log sources for monitored processes. For files that are not detected or windows events add custom files configuration.

• Any data can be ingested
• Almost limitless storage
• No schema definition necessary
• All data available at any time
• Indexless storage
• Massive parallel process
• Analyzes petabytes real-time
• Query via DQL (Dynatrace Query Language)

Logs can correlate data by directly correlating to user session & traces for more refined analysis for faster troubleshooting.

Collecting Logs

Settings -> Log Monitoring

Log monitoring - Available options

• Log ingest rules: Use this option to enable log monitoring for pre populated option/standard location.

Options:

1. Host perspective (Like /var/log/message) related to source data
2. Process groups perspective: related to process group data (Ex: Easy travel / maria DB etc)

Processing: Logs can be transformed through processing rules for common technologies. You can create your own processing rules like fetching apache error code. similar to regex.

Path: Settings -> Log monitoring -> Processing

Creating a log metric: With log metrics, you can use queries to create metrics from logs data for dashboarding, analysis, and custom alerting. Like counting how many HTTP errors from Apache logs.

Creating alert based on Metric: Create event templete: Title, description..
