How to use Pandora FMS from Microsoft Azure

In this article we will focus on our on-premise platform, or cloud monitoring after having installed Pandora FMS console in Microsoft Azure. The installation will be made with an automated script that installs the Community version and with a second script, it allows to update Pandora FMS to its Enterprise edition (Corporative), leaving a 30-day test version (Trial).

Requirements

In order to use Pandora FMS, it is necessary to meet the following requirements:

RequirementSettings
CentOS 8 Virtual Machine2 GB RAM, 40 Disk
(minimum)
WEB Console (Firewall)443 TCP (https)
Tentacle Agents (Firewall)41121 TCP (Tentacle)
SSH management22 TCP (SSH)
SSL CertificatePublic Certificate
CNAME aliasTo use your own domain

 

Note: The script is only supported on CentOS 8

Before continuing, let’s see some screenshots of a Pandora FMS console running in Microsoft Azure:

For the script to work properly, it is important to use a supported virtual machine for this process. To do that, go to Microsoft Azure console (https://portal.azure.com) and select the following:

Azure Services -> Create Resource

In the Marketplace, look for CentOS 8.2 and select the following image:

Note: The script works using this image. In case of using another, if the repositories are set up differently, the installation may fail.

The rest of the process can be seen in detail in this guide.

Why monitor from Azure (Cloud)

Technology evolves over time and as a result of this evolution, our way of implementing changes. Many customers already have part of their infrastructure in the cloud. Today there are many hybrid on-premise (data center) + Cloud environments and many companies have their mail in SAAS (Software as a Service) format, as it is the case with Google Apps and Office 365.

Bearing this in mind, is Pandora FMS ready to run in the Cloud? The answer is simple. Yes, Pandora FMS is capable of being executed from the Cloud without any kind of difficulty. Software agents send information using TCP port 41121 (Tentacle). That way, all modules created in the software agents, whether Windows or Linux, will be reflected in your Pandora FMS implementation

After this short introduction, let’s see Pandora FMS running directly in Azure. As you could see from the functional outline, at the beginning of the article, I am monitoring my smart home from Azure. Let’s see the tactical view:

microsoft-azure

We can see in this case that 52 agents are being monitored, where there are 591 modules, 588 of them in Ok status (Green), 2 in Failure (Red) and 1 in Alert (Yellow). The tactical view is very useful to quickly find out the health status of your platform.

Another very interesting view in Pandora FMS is the group view:

microsoft-azure

In this view we can group our agents to be able to organize in a simple way the technologies that are being monitored, the place where the agent is or any data that helps us quickly find the monitors that we are creating.

Useful features

Running any application from the Cloud brings new challenges, even if we have a hybrid infrastructure. Bearing in mind that it is a reality in many companies, we are going to focus on the advanced features that Pandora FMS has and that can help us work efficiently by having our solution running in Azure.

An extremely useful Pandora FMS feature is Discovery; one of the options is to perform a network sweep (scan) and sum all the ICMP, SNMP and WMI devices in a very easy way. This is very simple if the agents are on the same network as that of Pandora FMS server or if they have a network connection from another branch with a site-to-site tunnel for example. But all this does not happen having Pandora FMS in Azure; so what happens? Do we lose this feature?

The answer is very simple, we do not lose this feature, we can use it with a Satellite Server (only in Enterprise version).

It allows exploring and detecting new systems, monitoring remotely, executing remote plugins and allowing forwarding data files from the software agents to the main server, working as an agent proxy. It sends the monitoring data as XMLs through a Tentacle connection, so it does not require connection to the database.

Here is a link to the official documentation on Satellite Server and below some screenshots.

It is important to bear in mind that the SNMP values seen in the graphs are generated automatically, only giving as values the IP of the device and the SNMP community that it must check.

Remote Configuration and Collections

Another feature available only in the Enterprise version and very useful for companies with many agents is remote configuration and collections, which allow us to solve two great challenges running Pandora FMS in Azure; the first is to manage the agents 100% from the WEB console and the second is to distribute agent plugins in a simple and efficient way that does not require any additional configuration to work in Azure.

Cloud Monitoring from Pandora FMS

Pandora FMS is constantly evolving according to the evolution of technology itself. Bearing in mind that many companies use Office 365 and virtual machines running on Azure, is it possible to monitor them natively?

The answer is very simple: yes, it is possible, you can make a query using Office 365 APIs and obtain the status of the services that are part of the solution.

As for Azure virtual machines, from Discovery it is possible to configure the automatic discovery of your infrastructure running on Azure.

In this case, we see 2 virtual machines, one is running and the other is off, as well as a sum of the consumption in the southcentralus datacenter.

Practical Case on Monitoring from Azure

To close this article I am going to share how I can see the health status of my smart home solution based on openHAB.

To run the solution, I am using two Raspberry PIs, where a key value is to know the working temperature of each computer.

To finish off, here you have a service view (Enterprise feature) that allows you to build a view of any application based on the business.

Conclusion

Pandora FMS is a tool that allows you to monitor the health of your infrastructure by running the solution from the Cloud, in this specific case from Microsoft Azure.
