and how the new features in Query Log Analyzer 1.0.2 support that
Since Neo4j version 4.0 the query log possibilities have been extended. Meanwhile version 1.0.2 of the query log analyzer was released.
We will show how this release supports these new query logging features and how it is now possible to read the log files directly from the server.
Please note that Query Logging is only available in the Enterprise Edition. But that edition is available for free in Neo4j Desktop and for startups.

With the release of Neo4j 4.0 my ‘Graph Apps’ for the Neo4j Desktop needed an update. The new Neo4j version, is a very big update with a lot of new features. An important feature is multi-database where you can run more than one graph database on a Neo4j Server.
You can install both apps into Neo4j desktop from: https://install.graphapp.io
The first version of this tool as described here was able to analyze an uploaded
query.log file. I also gave a presentation at NODES 2019
With this new version the following new features are added:

Over the years working with Neo4j, I was creating small tools to help me to understand what kind of data a Neo4j database contains. I wanted to know what the label and relationships counts were in the database and which properties are there to give a good estimate, how a database will grow over time.
With the availability of Neo4j Desktop, I created a Neo4j Desktop App based on the small tools I used before called Analyze Database. While doing this I added two more tools. Live Count which counts all the Nodes per Label and Relationships per Relationship Type…
Make your slow cypher queries running fast
In this post I will explain about common causes of query performance degradation in the Neo4j server. This is a follow up on the Meet the Query Log Analyzer story earlier this week.
The Query Log Analyzer App helps you to find quickly the slow queries on the Neo4j server.
Caching and Disk IO
The Neo4j database maps the data files from disk to the Page Cache. When you do a query and the data is not in Cache the data will be loaded from disk. The second time the query is executed the…
The Query Log Analyzer is a Neo4j Desktop App to help you to understand the query log file of a Neo4j Enterprise server.
When you experience unexpected slowness of Neo4j, your queries may be inefficient or the query load on the server is too high. A good step is then to enable the query log via the
# If the execution of query takes more time than this threshold,
# the query is logged. If set to zero then all queries
Normally you will set a threshold to log only…
