We’re having Newrelic application monitoring in many projects integrating with classical relational databases and mongo and recently started a new project with the ArangoDB as a multi-model graph database.
I cannot find any article on the web having both ArangoDB and Newrelic creatures in the topic.
Did anyone try to monitor a backend application with ArangoDB using Newrelic? Is it possible? Is it difficult?
If anybody knows, please share knowledge, describe available strategies and possible tactics.
We have a cookbook, that is meant for integration and monitoring of ArangoDB instances using Prometheus and Grafana.
https://docs.arangodb.com/devel/Cookbook/Monitoring/Collectd.html
There are to ways you could go about this. If you have some experience with Newrelic and feel motivated to adopt the above cookbook to Newrelic, we would not hinder you and help wherever we can.
Or you would go to our github repositpry and file a feature request after having stared us :) there.
In either case, you'd be awesome.

I'm trying to use Apache Flink's Table concept in one of my projects to combine data from multiple sources in real-time. Unfortunately, all of my team members are Node.JS developers. So, I'm looking for possible ways to connect to Flink from NodeJS and query from it. In Flink's documentation for SQL Client, it's mentioned that
The SQL Client aims to provide an easy way of writing, debugging, and submitting table programs to a Flink cluster without a single line of Java or Scala code. The SQL Client CLI allows for retrieving and visualizing real-time results from the running distributed application on the command line.
Based on this, is there any way to connect to Flink's SQL client from NodeJS? Is there any driver already available for this like Node.JS drivers for MySQL or MSSQL. Otherwise, what are the possible ways of achieving this?
Any idea or clarity on achieving this would be greatly helpful and much appreciated.
There's currently not much that you can do. The SQL Client runs on local machines and connects to the cluster there. I think what will help you is the introduction of the Flink SQL Gateway, which is expected to be released with Flink 1.16. You can read more about that on https://cwiki.apache.org/confluence/display/FLINK/FLIP-91%3A+Support+SQL+Gateway
Another alternative is to check out some of the products that offer a FlinkSQL editor on the market, maybe that is useful path for your colleagues.
For example:
https://www.ververica.com/apache-flink-sql-on-ververica-platform
https://docs.cloudera.com/csa/1.7.0/ssb-overview/topics/csa-ssb-intro.html
Note that this is not exactly what you asked for, but could be an option to enable your team.
We are looking into options to monitor our Acumatica instance to identify performance issues on the application level as well as the SQL server level. We have experience with newrelic and a few others, but also read about Retrace (https://stackify.com/retrace/) which looks worth trying.
I'm curious to know if it's possible/recommended to install such tools within Acumatica?
Does anyone have any experience or feedback on the topic?
Acumatica includes a built-in request profiler that can be used to monitor requests, performance and SQL. Probably not as sophisticated as New Relic, but powerful enough when you have performance issues to resolve.

I have a few questions regarding the integration of the two tools. Not technical questions and how to setup( i will have my fun with that later ) but more on the course of the project and the direction, seeing that JanusGraph is still very young.
I am starting a new project and already decided to use Cassandra for storage and using a graph on top sounds very appealing to me.
A couple of things that i would like to know in advance before i take that road.
JanusGraph is very young and it picks up from where Titan left about a year or so ago. There is gap there but the fact that is part of the Linux Foundation and all the big players are going to support it sounds promising. Is it safe to assume at this point that JanusGraph is here to stay? Would it be safe to depend on Janus as a startup project? And follow development of course and be up to date as much as possible.
Cassandra. Titan/JanusGraph integrates with Cassandra 2.1.9 using the thrift api which will be deprecated eventually in Cassandra 4. I know that work is being done at the moment to make janus work with Cassandra 3 and eventually work with CQL as well. Is it safe to start with existing janus and Cassandra 2.1.9 and deal with the migration later on? Will it be a huge task for a startup to handle?
Production ready JanusGraph.(This question relates to any kind of software in it's early stages and whether it's safe for a start up to use). As i understand it, it will take some time for JanusGraph to be production ready and catch up with the rest of the tools it integrates with( although work is being done as we speak:)). Again would it be safe to start using Janus at this point and follow development and finally migrate to a production ready version? What is the overall roadmap for JanusGraph?
My concern in general is whether the combination of the tools is a safe choice for a start up. The whole stack is already new to us and we are excited to try and learn but we will hit a migration period pretty quickly. Is it something that you would do/recommend? Is it a suicide?
Please share your thoughts and keep in mind that it doesn't have to be about the stack i am talking about. It could be any startup company dealing with any kind of software in its early stages.
Cheers
Full disclosure, I'm a developer for JanusGraph on Compose.
It's as safe as any other OSS software project with a large amount of backers. Everyone could jump on some new toy tomorrow, but I doubt it. Companies are putting money into it and the development community is very active.
There is a CQL backend for Janus that's compatible with the Thrift data model. Migration to CQL should be simple and pretty painless when 0.2.0 is released.
I know there are already people using Titan for production applications. With JanusGraph being forked from Titan, I think it's pretty reasonable to start in with JanusGraph from everything I've seen. As far as a roadmap, I'd check out the JanusGraph mailing list (dev/users) and see what's going on and what's being talked about.
Disclosure: I am one of the co-founders of the JanusGraph project; I am also seeking out and adding production users to our GitHub repo and website, so I may be slightly biased. :)
Regarding your questions:
Is it safe to use?
The project is young, but it is built on a foundation of Titan, a very popular graph database that's been around since 2012 and has already been running in production. We have contributors from a number of well-known companies, and several companies are building their business-critical applications directly on JanusGraph, e.g.,
GRAKN.AI is building their knowledge graph on JanusGraph
IBM's Compose.io has built a managed JanusGraph service
Uber is already running JanusGraph in production (having previously run Titan)
several other companies run JanusGraph as a core part of their production environment
We are also starting to identify companies who will provide consulting services around JanusGraph in case someone needs production-level support for their own self-managed deployments.
So as you can see, there is significant interest in and support for this project.
Cassandra upgrade
#pantalohnes answered this question; I won't repeat it here.
Production readiness
As I linked above (GitHub repo and website), we already have production users of JanusGraph which you can find there. Those are just the companies that are publicly willing to lend their name/logo to the project; I'm sure there are more. Also, Titan has been running in many production environments for several years; JanusGraph is a more up-to-date version of Titan, despite the low version number.
I am also speaking with other companies who are planning to migrate to JanusGraph soon; look for announcements via the #JanusGraph Twitter handle to learn about more production deployments.
Does Anyone know to achieve, or have any resources about, muti tenancy involving these technologies?
Additionally, is it recommendable to store sensitive data in a relational database and other kinds of data in NoSQL databases?
Thanks in advance.
Cloudant has been providing multitenancy clusters for a few years now. The technology is based on CouchDB but with a bunch of enhancements. Once you outgrow the multitenant cluster you can "hit a button" and flip over to a private cluster, all of which Cloudant will manage for you.
Feel free to reach out to me offline if you want more info or check out http://www.cloudant.com.
I'm less familiar with the hosting options for those other technologies, so I wouldn't feel good about recommending one. In full disclosure I work at Cloudant, but I often recommended them before they hired me. :)
Cheers.
I am developing a site using following technologies,
Ruby on Rails,(ruby 1.8.7,rails 2.3.5)
Cassandra 0.6.8,
I want to index the Cassandra Database using Lucandra,
How do I do this?
Is there any RESTful APIs or any web services available for this, so
that I can push the data to index database?
Please share if any ROR example using Lucandra, that really help us to
move forward.
Or Guide me some steps to achieve this.
I am googling for 3 days and I am not getting any examples using
Lucandra in ROR.
Your help will be appreciated in advance
The Solandra project which is replacing Lucandra no longer uses
thrift, only Solr. http://github.com/tjake/Lucandra
This means you can use any of the Solr supported gems like
acts_as_solr
I'm recommending elasticsearch. It has rest api, ruby & rails clients.
https://github.com/angelf/escargot
https://github.com/grantr/rubberband
Elasticsearch is the most advanced free search solution in the world today. It's based on lucene, has High Availability, fault tolerant, partitioned, high performance, scalable, state of art technologhy , open source, more simple than solr... It's success belongs to it's author Shay Banon. He has years of experience as an architect in this field. Solr (and solandra) is nowhere near of it. Simply investigate both, you'll see yourself.
my best
