Monitoring a Fortigate Firewall from Centreon

In this post we will see how to monitor our Fortigate firewalls from a Centreon or Nagios or whatever we have 🙂. We will do it through SNMP queries and we will be able to know the status of its chassis at all times, the status of the cluster if we have one, the use and consumption of network interfaces, if we have VPNs the same, know if they fall, The sessions, etc, etc… if you have a Fortigate, This is your post!

Monitoring Nutanix from Centreon

If we have a Nutanix in our environment… Why don't we centralize all the information you give us in our Centreon monitoring system?? Not only to better manage alerts, but to store all its metrics and be able to work on them as we see fit, this is a post with full detail on how to fully monitor Nutanix!

Nagios – Monitoring an MGE UPS

If we have a UPS or a UPS in our organization, why not monitor it? Why not know the status of your batteries? If we have any problem that is surely critical, I think it is reasonable to centralize and control it from our Nagios or Centreon machine in order to have any problem we may have under control and receive its notifications. So if you are interested in knowing the status of your UPS, take a look at this document!

Monitoring a Linux computer with Centreon, example with a Raspberry Pi + Temperature of your CPU

I'm going to put this post because of all the requests I've been receiving on how to monitor a Linux server. As obviously depends on the distribution, today we have an example with a Debian and more specifically we will see it on a Raspberry Pi that carries Raspbian. We'll monitor basic metrics like CPU, RAM, Swap Memory, Disks, Network Traffic, Uptime… And in the end we will see something very interesting!

Nagios – Monitoring active processes on Windows or Linux

Very good! I leave you with a document that will be of help to us as long as we want to verify that we have a program running on any computer in our organization. We will see the necessary steps to be able to monitor if a remote computer, whether Windows or Linux, has any process running, and alert us in case of its fall. In addition, if we are interested, we could monitor its CPU or RAM consumption., all this only through SNMP!

Monitoring thanks to snmpwalk

Continuing with documents on Nagios or Centreon, Let's go with a post that may be in common use, above all, when we need to monitor something by SNMP and the Internet gurus have not developed a script that we need. We will see then, how to query over SNMP what a device might 'spit out'’ Thanks to SNMPWALK and then we will monitor it! And at the end of the document we'll look at how to monitor the traffic of any network device that has SNMP enabled as well!

Nagios – Monitoring Citrix NetScaler

Continuing a little with Citrix elements that we can monitor… what less than our NetScaler! In this document, we'll see how to monitor a Citrix NetScaler VPX virtual appliance that is currently the Gateway for my Citrix XenDesktop organization. We will monitor its basic consumption such as CPU through SNMP, Memory or disks, but also the connections, your network interfaces or certificates!
