# neo4j-log-analyzer
Parsers and analyzes Neo4j query logs to build a structural summary and discover frequent patterns.
## Input:
- 1 or more folders containing query.log files.
## Output:
- For each of the logs:
- For each unique Cypher query:
- The type of query (read, write, custom procedure)
- The number of edges in the query graph (0, 1, 2, 3, 4, 5-9, >10)
- Structural properties of the query (chain, loops, tree, forest)
- Running time for the different executions of the unique queries.
- A list of frequent sub-patterns as mined from the query graphs.
- Summary information over all logs:
- The total counts of the number of unique queries, read/write queries and custom procedure calls.
- The number of k-length patterns that are frequent (>10% of query count)
- Aggregated information of the its queries' structure and shapes.
## How to run:
- Run the main class (LogAnalyzer) with a single argument (the location of your Neo4j query log folders). When processing many logs, a large amount of assigned memory is recommended. (i.e. run with the `-Xmx16000m` parameter)
## Notes:
The log analyzer requires a modified version of Neo4j 4.0 with a special Cypher parser class in Scala. This class is added to the repository: `scala/CypherSpecialLogParsing.scala`.
