Log Tank Service (LTS)

Various services and devices can be monitored using log data in order to ensure that they are running error-free. With the Log Tank Service (LTS), the Open Telekom Cloud offers a service which records log files from different sources and archives them efficiently. The Log Tank Service can, for example, consolidate logs which are distributed across different systems in a single location. The log files are not only saved here; they can also be searched in a targeted manner. This provides operations staff with real-time insights, which help them identify and remedy errors and error sources.

The Log Tank Service (LTS) in the Open Telekom Cloud has a full-text search and indexing function. The sources from which the logs are (automatically) recorded are continuously being expanded upon. Furthermore, the LTS enables the introduction of guidelines which move LTS data into object storage. Logs can be organized into groups and streams. Alongside the search and transfer functions, the LTS also supports (automatic) monitoring of services and devices, as well as triggering of alarms.

Using this service provides you real-time log processing. The data loading interface is invoked once every 3 seconds.

The LTS helps you quickly and efficiently perform real-time decision-making analyses, device O&M management, and user service trend analyses.

The LTS maximizes the availability and performance of cloud services and applications by analyzing and processing massive log data.

LTS enables the rapid identification and resolution of application issues by aggregating logs across distributed environments from e.g. Elastic Cloud Servers (ECS), Cloud Container Engine (CCE), Elastic Load Balancer (ELB), API Gateway (APIG) and many more. This capability allows quick pinpointing of root causes, reducing downtime and improving service reliability. By analyzing log data, you can assess system health, identify performance bottlenecks, and understand usage patterns, enabling proactive measures to ensure consistent performance and user satisfaction.

The LTS plays a crucial role in enhancing security and ensuring compliance. It allows for the centralized collection and management of log data from various cloud services and applications, simplifying log analysis and monitoring across multiple systems. By recording and storing account activity and API usage, LTS helps detect potential security threats, unauthorized access attempts, and ensures compliance with governance standards and policies. The LTS is integrated with various security services offered by the Open Telekom Cloud, for example Cloud Firewall (CFW), Host Security Service (HSS), Web Application Firewall (WAF).

With LTS, you can perform real-time monitoring and analysis of your log data. The service allows you to set up filters to extract specific data points from your logs and create alarms based on these metrics. This enables you to monitor and receive alerts for specific phrases, values, or patterns occurring in your log data. The alerting feature supports continuous validation of alarm conditions to automatically raise and clear alerts. Alarm actions allow notifications to be sent via the Simple Message Notification (SMN) service or to trigger automated recovery procedures with FunctionGraph (FG).

• Log injection: Collect data from various sources
• Log organization: Define groups for log streams
• Host groups: Configure settings for multiple hosts & containers
• Stream tagging: Add custom tags for log streams
• Log search: Use powerful query language to search data
• Log transfer: Export logging data for further analytics
• Log alarms: Define queries to trigger alarms based on log content
• Action rules: Define rules to process log alarms

To transfer log data for long-term storage and archiving, you can enable the log transfer function. After enabling this function, LTS transfers logs to the Object Storage Service (OBS) periodically. OBS automatically converts the logs into objects and writes them to a specified bucket. You can then read and process these logs directly from the OBS bucket. The log transfer function is disabled by default, requiring manual activation. Once enabled, you can modify its settings as needed. If you no longer require the log subscription function, you can disable it. For further details, refer to the Log Transfer chapter in the LTS documentation.
