Very good!! I wanted to share this document for those who need to monitor digital certificates, We will be able to confirm its validity to prevent any fall. As we all know, These are critical points in our organization, since if a certificate were to expire, the service offered by said product would fall, no matter how much we have invested in data centers in high availability, Clusters…
What's up txabales!!! We come with something that can fit us all! Anyone who has a Nagios or Centreon environment already set up (or want to cheer up), Why don't we control if our public IPs or the IP addresses through which our organization's mail leaves are blacklisted?? So far we know how we found out that you are on blacklists… Why either the mail doesn't go out or doesn't come in?, No? Get ahead of the curve and check the main blacklists!!
If we are concerned about keeping our Microsoft Windows environment up to date and controlled, we can also help ourselves with monitoring to control the pending patches that our Servers have in Windows Update. Let's continue to centralize everything we can in our management panel, let's control all our infrastructure from Nagios or Centreon and live more relaxed!
Well, Well… Let's put a little more txitxa in our Nagios, Centreon or whatever we got, We will continue with something very interesting for those who want to monitor more advanced items! We will use a small agent that will be installed on remote Windows or Linux computers, For what? Well, among other things, to execute scripts on these computers. We can run any PowerShell script, Batch, VBScript, Perl… and then read the result of the command and discuss it with Nagios!
In this post we will see how Nagios can help us monitor the existence of snapshots in our virtual infrastructure, Everyone knows the danger of having snapshots or leaving them for long periods… Hanging backups that leave half-baked snapshots… To combat this, We'll automate a periodic check-in with a great script!
Let's start getting more out of monitoring, Something fun and enjoyable to watch, at least something different and it doesn't have to be as technical as it has been until now. We are going to integrate into our Nagios and/or Centreon a layer of visualization of interactive maps or drawings, it is nothing more than taking the monitored items to fully customized live drawings, are drawings of logical schemes, of photos of the DPC, SMTP traffic… of what our imagination gives us!
We continue with more things that we can monitor with Nagios or Centreon! If we have an HP MSA storage array in our organization, either fiber or iSCSI, This is your document! In a simple way, we can absorb the information that we are interested in controlling through SNMP, Be the state of the hard drives, The controllers, Volumes, RAID, Temperatures, Chassis Condition, Alerts, etc, etc…
Another very common and simple check at the same time is the monitoring of a TCP port if it is up and responds in an adequate time. In this document, We will see how to monitor the availability of some ports offered by our servers, are critical ports like 80TCP for our websites, 25TCP for Mail Servers…
Once we have our Windows computers monitored, perhaps we are interested in monitoring something as critical as the services they offer, No? Also, through SNMP we will be able to consult if SQL services, Exchange or any other service that has your computer installed is up or down.
In this document, we'll look at all the steps needed to be able to monitor an ESXi host, we will see the most common parameters and the values that we can obtain to have a controlled environment thanks to Nagios and Centreon! All the information we can obtain is amazing! In other documents we will see other information that we can obtain from vCenter and its VMs, Today the hosts are playing!
