I agree with what you are addressing as I’ve always thought the big elephant in the room regarding Cassandra was that you had to use all these other tools, each of which requires updating, configuring changes, and that too much attention had to be paid to all those other tools instead of what your trying to accomplish; when instead if addressed it all could be centralized, internalized, or something but clearly it was quite doable. 


Questions regarding where things are at:


Are you using AxonOps in any of your clients Apache Cassandra production clusters?


What is the largest Cassandra cluster in which you use it?


Would you recommend NOT using AxonOps on production clusters for now or do you consider it safe to do so?


What is the largest Cassandra cluster you would recommend using AxonOps on?


Can it handle multi-cloud clusters?


Which clouds does it play nice with?


Is it good for use for on-prem nodes (or cloud only)?


Which versions of Cassandra does it play nice with?


Any rough idea when a download will be available?


Your blog post at https://digitalis.io/blog/apache-cassandra-management-tool/ provides a lot of answers already!  Really very promising!

Hi Kenneth,


Thanks for your great feedback! We're not trying to be secretive, but just not amazing at promoting ourselves!


AxonOps was built by digitalis.io (https://digitalis.io), a company based in the UK providing consulting and managed services for Cassandra, Kafka and Spark. digitalis.io was founded 3 years ago by 2 ex-DataStax architects but their experience of Cassandra predates the tenure at DataStax.


We have been looking after a lot of Cassandra clusters for our customers, but found ourselves spending more time maintaining monitoring and operational tools than Cassandra clusters themselves. The motivation was to build a management platform to make our lives easier. You can read my blog here - https://digitalis.io/blog/apache-cassandra-management-tool/


We have not yet created any videos but that's in our backlog so people can see AxonOps in action. No testimonials yet either since the customer of the product has been ourselves, and only just released it to the public as beta few weeks ago. We've decided to share it for free to anybody using up to 6 nodes, as we see a lot of clusters out there within this range.


The only investment would be a minimum amount of your time to install it. We have made the installation process as easy as possible. Hopefully you will find it immensely quicker and easier than installing and configuring ELK, Prometheus, Grafana, Nagios, custom backups and repair scheduling. It has certainly made our lives easier for sure.


We are fully aware of the new features going into 4.0 and beyond. As mentioned earlier, we built this for ourselves - a product that does everything we want in one solution providing a single pane of glass. It's free and we're sharing this with you.

Sorry, Nitan was only making a comment about this post but the comments I’m making are to AxonOps. 


It appears we don’t have a name for anyone at AxonOps at all then!  You guys are going to need to be more open.

A few thoughts:

Isn’t it a lot to expect folks to download, install and evaluate the product considering,

·         You aren’t being very clear about who you are,

·         You don’t have any videos demonstrating the product,

·         You don’t provide any testimonials,

·         You have no case studies with repeatable results, ROI, etc.  All the normal stuff.

·         What about testing?  No one knows how well tested it is.  Why would we download it?


Don’t forget that the open source Cassandra community is already addressing ways in which Cassandra itself will be able to do several of the things that you listed. 


How much added value are you providing with this product?  It’s up to you to make the case.  You’ll have to spend more time on the business side of things if you want to do any business.

It's not an open source product but free up to 6 nodes for now. We're actively adding more features to it but it currently supports the following features:


- Metrics collection and dashboards

- Logs / events collection and dashboards

- User configurable health checks

- Alerts / notifications integrations to Slack, Email, PagerDuty (and more to come)

- Cassandra backups and scheduling against local filesystem, AWS S3, Azure Storage, Google Cloud Storage (and we're adding more cloud vendors)

- Cassandra Adaptive Repair - repair speed is dynamically controlled based on the cluster performance


We'll be adding more Cassandra operational features as well as security enhancements.


The installation instructions are available from https://docs.axonops.com.


Let us know what you think.
