Log Tank Service
Aggregate, structure, visualize, and analyze log data for actionable insights into O&M. Query logs with instant results. You can also transfer logs to OBS for long-term storage or to DMS for data retrieval.


  • Collection and Transfer

    You can use ICAgent, SDKs or APIs to collect logs from different sources, such as hosts, hybrid cloud or multi-cloud environments, and HUAWEI CLOUD services including ELB, VPC, APIG, CTS, WAF, DevCloud, and AOM. Logs can be transferred to OBS or DMS for Kafka for long-term storage.

  • Search and View

    Exact or fuzzy searches with one or more keywords are supported. You can view logs in real time as they come in, and check the context of log events, which is very helpful when troubleshooting.

  • Analysis and Alarms

    LTS provides different methods and templates for you to structure logs, so you can query logs using standard SQL syntax. You can gain intuitive insights by visualizing log data in charts or dashboards. To keep track of system performance, you can set alarms on important metrics.

  • LogReduce

    LogReduce can recognize patterns in log data and group similar logs accordingly. Log grouping and intelligent alarm analysis help you analyze logs more efficiently (coming soon).

Statistical Analysis

Statistical Analysis

Logs are printed in a fixed format, so it is easy to turn them into structured data by parsing them into field-value pairs. You can then run SQL queries to quickly obtain statistical analysis.


Multiple Structuring Methods

Choose the method that suits your needs. Field-value pairs can be extracted intelligently from JSON-formatted logs. Templates are available for structuring logs from HUAWEI CLOUD services, such as ELB, VPC, and CTS. You can also use delimiters or regular expressions to extract field-value pairs flexibly.

SQL Aggregate Queries

LTS SQL is compatible with standard SQL queries, so if you are already familiar with standard SQL, you can get started with LTS with no learning curve involved.

Charts and Dashboards

Data can be visualized in full-screen dashboards or using various charts (line, bar, and pie charts).
