The Best Riak Database Monitoring Tools

The success of non-relational databases is not surprising, and over the years, they have gained solid ground in the enterprise world. Riak is an open-source, web-scalable database based on NoSQL and Dynamo database systems. Basho Technologies developed it. The software has been designed for fault tolerance, high availability, and great scalability.

Riak is an extensively distributed database software that provides reliable and scalable performance in various operational environments. Riak is available in free as well as commercial versions. In addition, the software is available for several platforms, including enterprise, web, cloud, and mobile platforms.

Explaining Riak

Riak is distributed across many nodes and is deployed without a master instance, hence, Riak is considered a fault-tolerant database. It does not have a single point of failure. Ideally designed for distributed cloud data infrastructures, Riak provides superior performance in high-volume read-and-write applications and can build cloud file systems.

The standard version of Riak is integrated with features like multi-node clustering and MapReduce. In contrast, the enterprise version is enabled with Simple Network Management Protocol (SNMP) monitoring tools, management tools, implementation, consulting services for architecture, and 24-hour technical support, along with the features provided in the standard version.

Riak has been architected for multiple advantages:

• Availability Riak replicates and retrieves data intelligently, so it is available for reading and writing operations, even in failure conditions.
• Fault tolerance You can lose access to many nodes due to network partition or hardware failure without losing data.
• Operational simplicity You can easily add new machines to your Riak cluster without incurring a larger operational burden; the same ops tasks apply to small clusters as large clusters.
• Scalability Riak automatically distributes data around the cluster and yields a near-linear performance increase as you add capacity.

Riak uses a simple key-value model for object storage. Objects in a Riak are stored in a flat namespace called a bucket, and it consists of a unique key and a value. Thus, you can virtually keep any content you want in a Riak – images, text, XML, JSON, and HTML documents; user and session data; log files; backups; and more.

Riak provides a straightforward, RESTful API as well as a protocol buffer interface. Riak has several client libraries, including Python, Java, Perl, Ruby, Erlang, PHP, .NET, and more.

Riak Variants

Riak comes in two variants: Riak KV and Riak TS. Both variants share the same Riak Core but have different use cases.

Riak KV is a scalable, highly available, and easy-to-operate distributed NoSQL database. One of the most important things is that it automatically distributes data across the cluster for fast performance and fault tolerance. What's more, Riak KV deals with Key-Value cases.

Riak TS optimizes IoT data and time series, and it also provides faster reads and writes that help makes it easier to query, analyze, and store time and location data. As a result, Riak TS forms the foundation for reducing the complexity of integrating and implementing active workloads for Big-Data, IoT, and hybrid cloud applications with the most flexible and available NoSQL database.

The Riak principle is based on Amazon's Dynamo Paper with heavy influence from the CAP Theorem. The database is written in Erlang and has fault-tolerant data replication and automatic distribution across the cluster for resilience and performance.

Essential yet straightforward Use Cases Of Riak

• For Ads Riak has repeatedly proven that it is one of the best choices for many use cases and serving advertising content is significant. Being such a popular database, Riak does content to different web and mobile users with low latency.
• For Sessions Storage Riak was initially created to serve as a scalable session store. However, the database evolved over the years and started doing as complex session storage as well. What was the reason for this evolution? Riak includes advanced features such as MapReduce, Bitcask, and others. User and session IDs are usually stored in cookies so that Riak can serve these requests with low latency. It is thus one of the most critical use cases for Riak.
• For Sensor Data Sensor data is nothing but the output of a device that detects and responds to some type of input from the physical environment. Many devices collect and send data at a given interval, and sometimes it becomes difficult to handle that data.  Riak helps you in such scenarios. It is considered one of the better options for storing sensor data.
• For Log Data Log data means the information about events that occur in an OS or other software or messages between different users of communication software. One of the ordinary yet essential use cases of Riak is storing large amounts of log data, and Riak can do the same with the help of MapReduce.
• For User Account Data Every company needs to handle user account data. It is very critical for any business. Hence, companies need a simple yet effective way to store that data. In this case, Riak can be a good storage option. Each account data in Riak could be stored as a JSON object in a bucket. What's more, object keys for the data can also be used, and to retrieve data; you can use a user ID.

Riak Database Monitoring Tools

collectd

collectd gathers statistics about the system it is running on and stores them. It collects metrics from various sources like the operating system, applications, log files, and external devices and stores this information or makes it available over the network. The statistics are then graphed to find current performance bottlenecks, predict system load, and analyze trends.

Certain factors set collectd apart from similar free, open-source projects. For one, it is written in C for performance and portability, allowing it to run on systems without a scripting language or cron daemon, such as embedded systems. The tool also includes optimizations and features to handle hundreds of thousands of metrics. It also provides powerful networking features and is extensible in numerous ways.

Last but not least, collectd is actively developed, supported, and well documented. However, collectd does not generate graphs, and monitoring functionality has only been added in version 4.3 but is limited to simple threshold checking.
