High Availability dalam PRTG Cluster adalah default feature

Dalam PRTG, fitur High Availability secara default kita akan mendapatkannya, dan dapat mengkonfigur PRTG dalam Cluster


PRTG Cluster Basics

One of the major new features in version 8 of PRTG Network Monitor is called “Clustering”. A PRTG Cluster consists of two or more installations of PRTG Network Monitor that work together to form a high availability monitoring system.
The objective is to reach true 100% percent uptime for the monitoring tool. Using clustering, the uptime will no longer be degraded by failing connections because of an Internet outage at a PRTG server’s location, failing hardware, or because of downtime due to a software upgrade for the operating system or PRTG itself.

How a PRTG Cluster Works

A PRTG cluster consists of one “Primary Master Node” and one or more “Failover Nodes”. Each node is simply a full installation of PRTG Network Monitor which could perform the whole monitoring and alerting on its own. Nodes are connected to each other using two TCP/IP connections. They communicate in both directions and a single node only needs to connect to one other node to integrate into the cluster.

Normal Cluster Operation

Central Configuration, Distributed Data Storage, and Central Notifications.
During normal operation the “Primary Master” is used to configure devices and sensors (using the Web interface or Windows GUI). The master automatically distributes the configuration to all other nodes in real time. All nodes are permanently monitoring the network according to this common configuration and each node stores its results into its own database. This way also the storage of monitoring results is distributed among the cluster (the downside of this concept is that monitoring traffic and load on the network is multiplied by the number of cluster nodes, but this should not be a problem for most usage scenarios). The user can review the monitoring results by logging into the Web interface of any of the cluster nodes in read only mode. As the monitoring configuration is centrally managed, it can only be changed on the master node, though.
If downtimes or threshold breaches are discovered by one or more nodes only the primary master will send out notifications to the administrator (via email, SMS, etc.). So, the administrator will not be flooded with notifications from all cluster nodes in the event of failures. BTW, there is a new sensor state “partial down” which means that the sensor shows an error on some nodes, but not on all.

Failure Cluster Operation

  • Failure scenario 1
    If one or more of the Failover nodes are disconnected from the cluster (due to hardware or network failures) the remaining cluster continues to work without disruption.
  • Failure scenario 2
    If the Primary Master node is disconnected from the cluster, one of the failover nodes becomes the new master node. It takes over control of the cluster and will also manage notifications until the primary master reconnects to the cluster and takes back the master role.

Sample Cluster Configurations

There are several cluster scenarios possible in PRTG.
  • Simple Failover. This is the most common usage of PRTG in a cluster. Both servers monitor the same network. When there is a downtime on Node 1, Node 2 automatically takes over the Master role until Node 1 is back online.

    Cluster - Simple Failover
  • Double Failover. This is a very advanced Failover cluster. Even if two of the nodes fail, the network monitoring will still continue with a single node (in Master role) until the other nodes are back online.

    Cluster - Double Failover
  • The following four-node-scenario shows one node in disconnected mode. The administrator can disconnect a node any time for maintenance tasks or to keep a powered off server on standby in case another node’s hardware fails.

    Cluster - Four Node Failover

Usage Scenarios for the PRTG Cluster

PRTG’s cluster feature is quite versatile and covers the following usage scenarios.

Failover LAN Cluster

PRTG runs on two (or more) servers inside the company LAN (i.e. closely to each other in a network topology perspective). All cluster nodes monitor the LAN and only the current master node will send out notifications.
Objectives:
  • Reaching 100% uptime for the monitoring system (e.g. to control SLAs, create reliable billing data and ensure that all failures create alarms if necessary).
  • Avoiding monitoring downtimes

Failover WAN or Multi Location Cluster

PRTG runs on two (or more) servers distributed throughout a multi segmented LAN or even geographically distributed around the globe on the Internet. All cluster nodes monitor the same set of servers/sensors and only the current master node will send out notifications.
Objectives:
  • Creating multi-site monitoring results for a set of sensors;

    —and/or—
  • Making monitoring and alerting independent from a single site, datacenter or network connection.

PRTG Cluster Features

  • Paessler’s own cluster technology is completely built into the PRTG software, no third party software necessary
  • PRTG cluster features central configuration and notifications on the cluster master
  • Configuration data and status information is automatically distributed among cluster members in real time
  • Storage of monitoring results is distributed to all cluster nodes
  • Each cluster node can take over the full monitoring and alerting functionality in a failover case
  • Cluster nodes can run on different operating systems and different hardware/virtual machines; they should have similar system performance and resources, though
  • Node-to-node communication is always secure using SSL-encrypted connections
  • Automatic cluster update (update to a newer PRTG version needs to be installed on one node only, all other nodes of the cluster are updated automatically)

What is Special About a PRTG Cluster (Compared to Similar Products)

  • Each node is truly self-sufficient (not even the database is shared)
  • Our cluster technology is 100% “home-grown” and does not rely on any external cluster technology like Windows Cluster, etc.

Pengakuan PRTG oleh tester Independen terhadap Quality & Performance




Here at Paessler, our QA team puts PRTG and all of its new features to the test on a daily basis. We do this to make sure that our customers can work with a powerful, reliable and easy to use network monitoring solution. Nevertheless, we are curious what catches the eye of independent experts when they test the software. In recent months PRTG was put under the microscope four times in a row. Network Computing (UK) and the German Institute for the Analysis of IT Components (IAIT) had a close look at the innovations that came with version 13.2 and version 13.3 whereas the German magazine Funkschau wondered how PRTG performs compared to the Open Source solution Nagios. In addition to the open source comparison LANline also examined how suitable PRTG is for small IT environments.
The lesson is clear: PRTG stands out due to its excellent usability, a very good price-performance ratio and continually added new features and functions.

Network Computing (UK): PRTG Network Monitor 13.2 from Paessler

"As Network Monitoring gets ever more sophisticated many products are struggling to cope with the increasing number and diversity of devices to be monitored as well as the volume of data generated. This can result in web console performance issues but Paessler has bravely tackled this head on by completely rewriting the front-end of its PRTG Network Monitor. It is much faster. [...]"
Network Computing puts it in a nutshell: "It [PRTG Network Monitor] is capable of presenting a lot of easily interpreted information using a single screen and the new web console's lightening quick responses makes network monitoring a pleasure, instead of a chore."
Read the complete review.

IAIT: A Completely Revised Monitoring Solution for Corporate Environments

The German Institute for the Analysis of IT Components (IAIT) writes about the monitoring software's innovations: "A new web interface and revamped mobile web GUI are some of the new features in the current PRTG version. The new web interface is a single page application (SPA) and works faster than the previous version, loading all settings in layer popups, so that users never lose the context of their work [...]. The page containing the overview of individual sensors has been reworked. The sensor data is now portrayed in a graph with a speedometer-like display. Another important new feature is the "PRTG for Android" App. The user thus receives an easy-to-use and easy-to-navigate overview of all monitored components."
In this test PRTG especially scores with its usability: "The tool's service range was always impressive, and now the web interface also provides a much better overview. It is not only much faster, but also presents the information required by each user in a clear and logical structure, which can be adjusted to accommodate the user's needs at any time. Paessler has taken a great leap forward with the new version [...], which should more than satisfy any system administrator."

Funkschau: Nothing Comes Without a Price

Funkschau's test laboratory asks: "Is a company really getting away cheaper with an Open Source product than with a commercial package?" In the realm of open source network monitoring, especially 'Nagios' is a huge hit. A basic argument for this kind of solution is of course that it's free. But Linux/Unix expertise is vital in order "to configure the product properly and get it running [...]. Whoever can afford professional support quickly ends up in the same price class as a commercial solution like PRTG where professional support is included in the price."
Funkschau concludes: "It quickly became obvious that this was a comparison like 'Dacia Logan vs. Mercedes S-Class. [...] PRTG takes the lead not only for installation and the startup configuration but also for configuration changes, user management and report creation. [...] A world of difference lies between the graphical user interfaces of the two products: on one side a fast, modern, complete and optically pleasing interface - on the other a rather archaic, rudimentary interface. [...] Despite my love for open source software, I have no choice but to name PRTG Network Monitor as the clear winner of this comparison."

LANline: Network Monitoring Can be Surprisingly Easy

The German IT magazine LANline found: "PRTG has clearly proven that network monitoring and its configuration do not need to be a nerve- racking project that utilizes several working days. In practice PRTG is absolutely sufficient and due to the saved amount of work the cost price pays off in any case: An explicit recommendation."
