Overview LogicMonitor's Log Analysis and Anomaly Detection tools enhance IT infrastructure monitoring by providing real-time insights into system performance and security. These features simplify log inspection, highlight potential issues through sentiment analysis, and detect anomalies to expedite troubleshooting and reduce mean time to resolution (MTTR). Key Principles Implement a comprehensive log collection strategy to ensure logs from all critical systems, applications, and network devices are gathered in a centralized location, providing a true holistic view of your IT environment. Ingest log data efficiently by applying indexing and normalization techniques to structure raw logs, reducing noise and improving analysis accuracy. Detect and identify issues early by leveraging real-time analysis with AI and machine learning to identify patterns and anomalies as they occur, enabling proactive troubleshooting. Use data visualization tools such as dashboards and reports to present log data intuitively, making it easier to spot trends and anomalies. Log Analysis Features and Methods Sentiment Analysis: LogicMonitor's Log Analysis assigns sentiment scores to logs based on keywords, helping prioritize logs that may indicate potential problems. Anomaly Detection: Automatically identifies unique deviations from normal patterns in log data, surfacing previously unknown issues predictively. Log Dashboard Widgets: Use Log widgets to filter and visualize log metrics in dashboard views, helping to quickly identify relevant log entries. Core Best Practices Data Collection Configure log sources to ensure comprehensive data collection across your whole IT infrastructure. Regularly review and update log collection configurations to accommodate changes in the environment. Data Processing Implement filtering mechanisms to include only essential log data, optimizing storage and analysis efficiency. Ensure sensitive information is appropriately masked or excluded to maintain data security and compliance. Analysis and Visualization Utilize LogicMonitor's AI-powered analysis tools to automatically detect anomalies and assign sentiment scores to log entries. Create and customize dashboards using log widgets to visualize log data pertinent to your monitoring objectives. Performance Optimization Regularly monitor system performance metrics to identify and address potential bottlenecks in log processing. Adjust log collection and processing parameters to balance system performance with the need for comprehensive log data. Security Implement role-based access controls (RBAC) to restrict log data visibility to authorized personnel only. Regularly audit log access and processing activities to ensure compliance with security policies. Best Practices Checklist Log Collection and Processing ✅ Ensure all critical log sources are collected and properly configured for analysis. ✅ Apply filters to exclude non-essential logs and improve data relevance. ✅ Normalize and index log data to enhance searchability and correlation. ✅ Regularly review log settings to adapt to system changes. Anomaly Detection and Analysis ✅ Utilize AI-powered tools to detect anomalies and unusual patterns. ✅ Fine-tune detection thresholds to minimize false positives and missed issues. ✅ Use sentiment analysis to prioritize logs based on urgency. ✅ Correlate anomalies with system events for faster root cause identification. Visualization and Monitoring ✅ Set up dashboards and widgets to track log trends and anomalies in real-time. ✅ Create alerts for critical log events and anomalies to enable quick response. ✅ Regularly review and update alert rules to ensure relevance. Performance and Optimization ✅ Monitor log processing performance to detect bottlenecks. ✅ Adjust log retention policies to balance storage needs and compliance. ✅ Scale resources dynamically based on log volume and analysis needs. Security and Compliance ✅ Restrict log access to authorized users only. ✅ Mask or exclude sensitive data from log analysis. ✅ Encrypt log data and audit access regularly for compliance. Troubleshooting Guide Common Issues Incomplete Log Data Symptoms: Missing or inconsistent log entries. Solutions: Verify log source configurations; ensure network connectivity between log sources and the monitoring system; check for filtering rules that may exclude necessary data. Performance Degradation Symptoms: Delayed log processing; slow system response times. Solutions: Assess system resource utilization; optimize log collection intervals and batch sizes; consider scaling resources to accommodate higher data volumes. False Positives in Anomaly Detection Symptoms: Frequent alerts for non-issue events. Solutions: Review and adjust anomaly detection thresholds; refine filtering rules to reduce noise; utilize sentiment analysis to prioritize significant events. Logs Not Correlated to a Resource Symptoms: Logs appear in the system but are not linked to the correct resource, making analysis and troubleshooting difficult. Solutions: Ensure that log sources are correctly mapped to monitored resources within LogicMonitor. Check if resource properties, such as hostname or instance ID, are properly assigned and match the log entries. Verify that resource mapping rules are configured correctly and are consistently applied. If using dynamic environments (e.g., cloud-based instances), confirm that auto-discovery and log ingestion settings align. Review collector logs for errors or mismatches in resource identification. Monitoring and Alerting Set up pipeline alerts for critical events, such as system errors or security breaches, to enable prompt response. Regularly review alert configurations to ensure they align with current monitoring objectives and system configurations. Conclusion Implementing LogicMonitor's Log Analysis and Anomaly Detection features effectively requires a strategic approach to data collection, processing, analysis, and visualization. By adhering to these best practices, practitioners can enhance system performance monitoring, expedite troubleshooting, and maintain robust security postures within their IT environments.

LM Logs Alert Tokens
We are looking at expanding into LM Logs and I am wondering are there any other hidden alert tokens? We are looking at what structure of the message we can send, and there feels to be a lack of items for LM Logs. Is there a way to pull out some of the log fields as part of the message? The closest we found so far is ##logMetaData## which gives us a json string of our custom fields. For future parties here is a little more detail. ##alerttype## logAlert ##datapoint## Log Pipeline Alert Condition Name ##datasource## LM Logs ##dsdescription## Raw Log Value ##dsidescription## Raw Log Value ##instance## Log Pipeline Name ##threshold## Log Pipeline Alerting Condition ##logMetaData## Log metadata fields included in alert from Pipeline Alert Conditions
LM Logs - Alerting
Hello, Just wanted to ask if there is a way to have alerting on multiple lets say IP addresses in a similar log message but not have it spam our ticketing system? Log Message 1 - 1.1.1.1 is down Log Message 2 - 2.2.2.2 is down Log Message 3 - 1.1.1.1 is down I want to be able to alert on 1.1.1.1 being down and suppress it for a day on duplicate alerts but if I have a alert query for "is down" then 2.2.2.2 will also get suppressed for a whole day as well when its a whole separate device/alert. I would also not be able to add all lets say 50 IP addresses that may alert as their own alert condition. Is there a way or is LM Log too limiting right now?LM Logs multiple capture group parsing
Ok, this is cool. I have some log data that has structured data in it (some text, then a python list of strings). I had started building out a parse statement for each member of the list, then thought I’d try just making multiple capture groups and naming multiple variables after the as fanboy. Turns out it completely works. It parses each capture group into the corresponding column with a single parse statement. I was halfway through writing out a feature request when I figured I’d give it a try only to discover that it completely works. Nice job LM Logs guys.
