Nagios – Monitoring Active Directory Status with NRPE

Another critical item that we will monitor will be the status of our respectable Active Directory, although we know that we will have him in cotton wool and we will pamper him, because Nagios or Centreon will also monitor it. Thanks to a script we will test your health on a scheduled basis, monitoring its status at all times, as well as that of the Domain Controllers, Therefore, another thing that we will get out of our heads and an automated system will do it for us, And if it fails… He warns us!

Nagios – Monitoring our Business Service (1/3)

Well, Well… I wanted to start with this type of posts and let's see how far we can go with our Nagios!! In a series of 3 documents we will see how to measure the SLA offered by different layers of our organization. We will not only use Nagios to monitor our Infrastructure Layer, we can scale by leveraging this foundation and monitor your Company's Operational Services, This is achieved by interrelating the infrastructure services already monitored with departmental needs, even monitoring the Business Service provided by your company.

Monitoring vulnerabilities with Nagios and OpenVAS

Well, Well! Another of the wonders that we can do with Nagios or Centreon is… the possibility of monitoring vulnerabilities in our computers! How great, truth?? We will rely on OpenVAS, We will use the checks we have to centralize them from a single console. We will be able to know how many vulnerabilities our servers put at risk and analyze their evolution with the graphs and of course receive alerts!

Nagios – Checking if we are on SPAM blacklists

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!!

Nagios – Checking Windows Updates

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!
