Benefits and features

Live Tail & Aggregate Live Tail
Logentries monitors, searches and correlates your log data in real-time, providing live tail visibility within seconds. All logs pass through a pre-processing engine, tagging and filtering important events in live mode. Filtering can also be applied automatically to only view events that contain particular definition – enabling you to easily identify the most important information within your data.

Using Logentries Live Tail you can:

  • Dynamically aggregate logs from across different machines into a single view.
  • Monitor a real-time live feed of all your individual logs.
  • Use easy search to tag and filter important events for immediate issue identification.
  • View Live Tail with client-side libraries (JavaScript, iOS and Android support) to track user sessions in real-time.

Out of the Box Heroku Support
The Logentries Heroku Insights provide out of the box views into your Heroku log data. A simple way to access and view Heroku errors, events, exceptions and other important information. All without a manual or time consuming search.

Simple, Powerful Search
Quickly find exactly what you need within your logs using keywords, regular expressions and field-level comparison. This is performed using our simple yet powerful search language (AND, OR, NOT and field level operators >,<, =, etc.).

Real-Time Alerting, Anomaly Detection & Inactivity Alerting
Logentries users can easily create automated, custom tags based on search criteria. Tags are automatically applied to logs coming into the Logentries service and highlighted in the log view. 

Tags contain custom terms or patterns that enable easy searching and filtering for events that matter the most to your business (e.g. fatal, errors, sales transactions.)

Alerts: Real-time Alerts are built using these custom tags and set to notify you and your team based on specific thresholds and preferences (e.g. up to 100 times/hour.) Users can select to be notified with real-time Alerts via text, PagerDuty, HipChat, Campfire, and other webhook APIs.

Logentries Inactivity Alerting
Logentries Inactivity Alerting monitors incoming log events to ensure that your critical systems and applications are still running as expected – like a heart beat. When an event does not occur, or system behavior changes, you are proactively alerted in order to identify and resolve the issue before it develops further.

Using Logentries Inactivity Alerting, you can:

  • Monitor standard, incoming events such as an application heart beat.
  • Receive real-time alerts based on log inactivity (i.e. receive alerts when something does not occur).
  • Monitor systems for specific server performance issues or configuration issues.
  • Monitor application availability 24/7.

Automated log-based anomaly detection
Logentries Anomaly Detection provides proactive alerting to abnormal activity or system events that enable you to proactively identify and resolve performance and security issues quickly. By using the Logentries real-time, pre-processing engine, you know within seconds when log event activity has occurred that is abnormal, or a deviation from the specified thresholds.

Using Logentries Anomaly Detection, you can:

  • Set-up real-time alerting based on deviations from important patterns and log events.
  • Easily customize Anomaly thresholds and compare different time periods.
  • Drill into specific key value data, not just generic events.
  • Receive alerts via text message, email, SMS, PagerDuty, HipChat, and Campfire.

Shareable Dashboards enable you to publish log data visualizations out to your team, and across your organization, to create one single data source for system and application performance. Shareable Dashboards allow for saved searches and analytics visualizations to also be shared via JSON or plugged into an existing centralized monitoring services. Currently Logentries supports sharing out to: Geckoboard and Hosted Graphite.

S3 Archiving
Logentries S3 archiving with AWS enables you to back-up your log data daily to long-term and cost effective triple redundancy storage in a SOC 2 compliant data center. This archiving capability is useful for compliance (e.g. PCI), security or just in case you need to access your logs at some point in the future.
With Logentries S3 AWS Archiving, you can:

  • Centralize and upload all log files/entries that have come into your account on a daily basis.
  • Automatically compress them to minimize your storage requirements and then back them up to your Amazon S3 bucket.

Team Annotations
Logentries Annotations give team members the ability to add notes, commentary and context to live log data for team-wide visibility and intelligence about what is happening across the systems. Annotations enable joint monitoring and identification of issues or specific events. Through annotation assignment and tracking, team members can communicate directly through the Logentries service and resolve issues quickly.

Using Logentries Annotations you can:

  • Share a single, team-based view of system activity and log events intelligence.
