Although NoSQL databases are not as well-titled their relational counterparts, they are selfsame popular with web applications. Apache Cassandra is likely one of the most popular of these databases. Just like whatsoever different type of database, these too, have to be monitored. And since it hind end be overwhelming to manually keep a stable sleepless eye on things, monitoring tools are the way to break down. Now, we're going to birth a look at five of the primo tools you tin expend for monitoring Apache Cassandra databases.

We'll begin aside introducing Apache Cassandra, in case you're not already familiar with the product. Next, we'll talk about NoSQL databases and what makes them different from more conventional types. Then we'll survive into great lengths into the subject of database monitoring, with a revolve about what there is to atomic number 4 monitored in databases. This will take us to the core of our discussion, the rattling optimal tools for monitoring Apache Cassandra databases.

Active Apache Cassandra

Apache Cassandra is a free and ASCII text file NoSQL database management organisation premeditated to handle large amounts of data across many commodity servers, providing high accessibility with no single item of failure. This spaced, wide column store database system of rules offers robust support for clusters spanning quaternary data centers with asynchronous masterless replication. This allows for contrabass latency operations. It has been used by big organizations such as Apple, Spotify, Netflix, and Uber. It is widely old in part because of its fault-tolerant, scalable and decentralized characteristics .

Cassandra was at the start developed at Facebook away Avinash Lakshman, one of the authors of Amazon's Dynamo, and Prashant Malik to power the Facebook inbox search feature. Facebook released the product as an open-source stick out on Google code in July 2008. A hardly a months later, i n March 2009, the project became an Apache Incubator project and about a year later, o n February 17, 2010 it graduated to a uppermost-take down visualise. The diagnose is a direct reference to the Trojan mythological prophet Cassandra, with classical allusions to a curse on an oracle.

Existence a NoSQL database, Cassandra uses Cassandra Query Nomenclature, a orbiculate interface for accessing Cassandra. CQ L , as it is usually referred to, provides an abstract stratum that hides implementation details of this structure and offers native syntax for collections and other common encodings. Language drivers are useable for Java, Python, Node.JS, Go, and C++.

The best tools for monitoring Apache Cassandra

So, straight off that we are all on the same paginate as to what it entails to monitor Apache Cassandra databases, here's our pick of some of the best tools you can use for that purpose. Many of the tools on our list are really applications programme monitoring tools. That should not come as a storm as Apache Cassandra is, in fact, just another application running on a host. Other tools are rather dedicated database monitoring tools but that does not necessarily mean they are better tools. It all depends on what your strict needs are.

1. SolarWinds Host & Application Monitor (FREE TRIAL)

The SolarWinds Server and Application Monitor was fashioned to supporte administrators monitor servers, their operational parameters, their processes, and the applications which are running on them. It tin can easily exfoliation from very itsy-bitsy networks to large ones with hundreds of servers—both physical and virtual—spread o'er multiple sites. The tool force out besides monitor cloud-hosted services like those from Amazon River Web Services and Microsoft Azure. This powerful tool also lets you monitor the public presentation and availability of Apache Cassandra servers happening Linux or Unix. It volition provide inside information on table service wellness, thickening statistics, and network tracking, letting administrators view all relevant parameters on a unified dashboard.

The be of the SolarWinds AppOptics APM service is $2 999/twelvemonth. This is an all-inclusive monetary value that will let you monitor busy 10 hosts, 100 containers, 100 traces per microscopic, and 1 000 custom metrics. You can optionally tot up additional traces for high-dealings websites at the cost of $1 000/year for an additive 100 traces per minute or custom metrics at the cost of $599/year for a 1 000 metrics. If you'd rather try the service first, a free, no-credit-card-needed 14-solar day trial is visible.

3. ManageEngine Applications Director

ManageEngine whitethorn not be likewise-called SolarWinds one of these days it's still another name that enjoys an excellent reputation among meshing and database administrators. The ManageEngine Application Manager deals with application management. You believably had figured it out by yourself. This is, however, a somewhat misleading epithet as it is as much a monitoring platform atomic number 3 it is a management creature.

This tool offers integrated application performance monitoring for all your host and application monitoring needs. IT ass also practice that for the inherent infrastructure components such as practical application servers, databases, middle-ware and messaging components, WWW servers, web services, ERP packages, virtual systems and cloud resources. In a a couple of row, this is an altogether-encompassing platform.

The ManageEngine Applications Manager provides comprehensive Cassandra performance monitoring and presidential term of all nodes in a cluster from a concentrated console.

Monitoring trends on these pools for increases in the pending tasks column can aid you plan add additional capacity. It arse also can help you deal with surcharge scenarios in your Cassandra surroundings by keeping a lookout for dropped messages. You can receive a log succinct of dropped messages along with the substance typewrite likewise as establish thresholds and configure alarms to notify you of dropped messages.

The ManageEngine Application Manager is in stock in several editions. Thither's a feature-moderate Free-soil edition as well as a Professional person and an Enterprise paid versions. Pricing starts at $945 and details can be obtained past contacting ManageEngine. A free 30-day trial adaptation is besides free.

4. Dynatrace

Dynatrace is another cloud-based Software as a Service (SaaS) offering. It can detect, solve and optimize applications automatically. Discovering and mapping a complex application ecosystem is simply a matter of installing the Dynatrace OneAgent. The service of process will leave you a high-fidelity catch of your entire application stack, from the public presentation of applications, obscure substructure, and user experience. It wish help you effortlessly detect problems along with their business enterprise impacts and root cause.

Last on our list is AppDynamics APM, an excellent application performance direction creature from Cisco. This tool will mechanically discover, map, and visualise your grievous client journeys done each practical application help and infrastructure component. It provides management teams with a one source of information to revolve about end-to-end performance in the linguistic context of the client feel, instead of monitoring individual services.

With Apache Cassandra databases, AppDynamics APM will discover them and add them to your monitoring environment. Once added, thither are various prosody you can monitor. For instance, monitoring Cassandra back-end communications bequeath permit you collect data on the average reaction time, errors per minute, and calls per minute, giving you an overview of how the armed service is performing.

This tool uses political machine learning to watch what normal performance is, effectively construction its own baseline of practical application performance. It allows the instrument to alert you whenever operation is non normal. There is direct integration with ServiceNow, PagerDuty, and Jira thusly that you prat be immediately alerted and fix problems before customers notice them.

The top-level is called APM Peak and it includes all the features from APM Advanced plus business performance monitoring, transaction analytics, and business journeys. Pricing can be obtained by contacting AppDynamics and a 30-day trial version is available.

Introducing NoSQL databases

A NoSQL database is a type of database that provides a mechanics for storage and retrieval of data that is modelled in way otherwise the tabular relations used in relational databases. These databases have been around since the unpunctual 1960s, yet they did not get referred to as "NoSQL" until a surge of popularity triggered by the needs of Entanglement 2.0 organizations in the early 21st century. NoSQL databases are more and more utilised in big data and substantial-time web applications. And while they do not use SQL per se—thu their name—few people favor to call them "Not only SQL" to emphasize the fact that they Crataegus laevigata brook SQL-like query languages—such as the CQL for Cassandra, or sit aboard SQL databases in polyglot persistent architectures.

There are single types of NoSQL databases, with different categories and subcategories. In the type of the Apache Cassandra database, IT is what is often called a wide column store. This specialised typecast of NoSQL database uses tables, rows, and columns, but unlike a relational database, the name calling and format of the columns can vary from row to row in the same table. Furthermore, wide of the mark column stores such as Apache Cassandra are not column stores in the original sense of the terminal figure. In genuine column stores, a columnar data layout is adopted such that for each one editorial is stored one by one on disk. AS for w ide column stores, they often support the whimsy of column families that are stored separately, with each such column family typically contain ing tenfold columns that are used together, similar to time-honoured relational database tables. A ll information w ithin a given column family is stored in a row-by-row mode, so much that the columns for a acknowledged row are stored together instead of storing each column one by one.

The Ins And Outs Of Database Monitoring

A great thing about Cassandra is how it comes with features equal fault allowance built-in. That, nonetheless, doesn't mean it is a set-and-forget solution. It unmoving needs to Be managed and monitored. For instance, the availability, performance, and security of a database system are important concerns for any database administrator. This is wherefore system administrators typically make use of versatile database monitoring tools.

Adequately set up database monitoring systems can bring several benefits. For example, active monitoring is forever better than a excited glide path atomic number 3 it is ever preferable to identify some warning signs before they become major incidents. Also, a proper database monitoring solution lavatory help rapidly pinpoint and resolve any affirmable issues. Whenever a organization experience unexplained slowdowns, the commencement place people start investigating is often the database. But monitoring is not just about performance. We're also talking about safekeeping an eye out for security-indirect events. Verifying backups is other common benefit of a good database monitoring tool.

There is nary universally constituted model for building a database monitoring surround. This is in part due to the fact that different businesses use different databases. And since each character of database may expose several types of metrics with varying levels of granularity, an important metric on one platform may not be important on another.

For instance, let's regard a few important differences between assorted types of databases that keister touch on your monitoring strategy. Relational databases are mostly used in online transaction processing systems. Data warehouse systems host large volumes of low-speed data. NoSQL databases are most frequently used in mobile or net apps to host metadata or condition information. In-memory databases are put-upon for fast performance. It is clear that the monitoring deman in each of these cases could be real contrary.

Furthermore, regardless what category of database you're using, new factors will regard the important metrics. The most important is certainly the software vender. The important metrics happening a Cassandra database, of instance, could be very different from those of a MySQL database surgery an Prophesier database. As wel, along-premise and cloud-hosted databases could have different monitoring of necessity with some metrics beingness important in one just non in the other. In the case of swarm-hosted databases, managed and non-managed database solutions bequeath consume different monitoring needs. Likewise, on-premise databases leave have different monitoring inevitably depending happening whether they run on physical operating theater virtual hardware.

What To Ride herd on

With so many metrics that seat be monitored, it can comprise resistless. And deciding what to monitor—and hat not—can be a discouraging endeavour. We've assembled a list of about metrics that we feel are important to monitor. They are traded infra under different categories of monitoring. Together, these metrics can paint a kinda detailed picture of the state of any database environment.

Infrastructure

The first category of monitoring prosody is infrastructure. It deals with the underlying hardware that your databases are running game on. Any variation of these metrics above of below fit thresholds will just about credible adversely affect early database prosody. For example, network overexploitation could trigger performance alerts in metrics from other categories.

Availability

Database availability is, of course, another category of metrics that is among the most important. Afterward all, you'll usually need to make sure that the database is available and accessible before looking at any unusual metrics. There are several ways that database accessibility can be monitored but among the most popular are the handiness of database nodes using informal protocols such as ping or telnet, the handiness of database endpoints and ports or failover events for overlord nodes and kick upstairs events for slave/peer nodes in multi-node clusters. Any of these parameters can be accustomed awake you of an accessibility issue but combining them will give you the best protection.

Throughput

Throughput oft refers to the meshwork data-carrying capacity. This is divers in the circumstance of monitoring databases, and we're really talking about the throughput of the database itself. Ideally, throughput metrics would at first be old to make up a public presentation service line or, even better, several baselines during unusual workload periods. For exercise, assembling metrics during month-end batch processing Oregon Black Friday sale events over several cycles will provide insight into a system's performance during those periods. And it may be quite polar from after-hours operations or weekday sales events. Baselines can then be accustomed make up unexceptionable thresholds for alarms. Whatever large deviation from usual values would and so need investigation.

Performance

The available performance counters could vary between different databases. They are typically reported on a specific time scale (per bit or per second, for example). These prosody fire provide a tell-tale signed of potential bottlenecks. Rightful as it was with throughput, creating baselines for these metrics is also suggested.

Scheduled Tasks

Database engines often automatically run repetitive tasks or regular jobs. Few systems, like Microsoft SQL Server or Oracle, birth a built-in job scheduling facility only others use the operational system of rules's scheduler—so much arsenic cron—or third-party schedulers. Careless of what the effective jobs are or how they are scheduled, what you demand to monitor is not merely that they ran simply, more importantly, what their outcome (succeeder or nonstarter) was.

Security

Security is much the most important facet of IT administration and this is just now as true with databases as it is with separate systems. Every bit such, it is important to observe the surety of your databases. And while you may not pauperization to monitor every single surety event, you might want to look at their aggregate meaning. Lease's explain. Suppose you're monitoring failed login attempts. A single failed login is most likely a sign of soul mistyping a password. Then again, if you see hundreds of them within a comparatively short metre frame, it could be the sign of an intrusion attempt.

Failed logins are certainly not the only security ingredient you deficiency to monitor. Database configuration transfer events are even as important. So are new substance abuser account creations or watchword changes. Once again, a single exemplify of these events is usually normal aside if repeated, they could be get for concern.

Logs

Logs are the set back where nigh database engines commemorate various types of information. They put up be made of a single single file or of several ones. Some systems log to school tex files piece others log to a database. Simply no matter how, where or what your database logs, your monitoring tools can help you with that too. The problem with logs is their quantity. Almost systems will create hundreds of log entries all hour, overmuch for a human to cope. Some monitoring tools bequeath capture the logs, parse and analyze them and create prosody dashboard from the information they contain. In fact, log direction is one of the heart requirements of database monitoring. There are several reasons for that merely the just about important is the breadth of information they control.

Swathe Up

All the tools we've just reviewed are great for monitoring your Apache Cassandra databases. But I'd corresponding to let you in on a secret. They're also great for all sorts of monitoring. All tools and services will admonisher quite an a few things likewise databases. In point of fact, this is probably what you should consider the almost when selecting your monitoring solution. Pick indefinite that leave not only monitor your databases simply also all your strange applications and servers. After all, you'll hold open rather a bit of effort by having only one tool around to deploy and you'll enjoy having a coordinated interface for most of your monitoring needs.
