| Pre-requisites | CustomLogsAma |
The Apache Tomcat solution provides the capability to ingest Apache Tomcat events into Microsoft Sentinel. Refer to Apache Tomcat documentation for more information.
This solution is dependent on the Custom logs via AMA connector to collect the logs. The Custom logs solution will be installed as part of this solution installation.
NOTE: Microsoft recommends installation of Custom logs via AMA Connector. Legacy connector uses the Log Analytics agent which were deprecated on Aug 31, 2024. Using MMA and AMA on same machine can cause log duplication and extra ingestion cost more details.

Data Connectors
This solution has 1 discovered data connector(s)⚠️ (not in Solution definition):
Connectors from dependency solutions:
- Custom logs via AMA 🔶 (dependency on CustomLogsAma)
🔍 Discovered: This item was discovered by scanning the solution folder but is not listed in the Solution JSON file.
🔶 CLv1: This connector ingests into a table that uses the legacy Custom Log V1 schema format with type-suffixed column names (e.g.
_s,_d,_b,_t,_g). Note: identification is based on column name suffixes which are also permitted in CLv2, so this classification may not always be accurate.
