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!
In this document we are going to hallucinate… especially if you are a fan of graph measurement and want to exploit them… we will be able to export the results of our Centreon to a machine with Grafana and obtain the best solution for the visualization of our data… The dashboards that we will be able to generate will be impressive, We will customize them to our liking, combining metrics or intervals of each item that we have monitored with Centreon. And super simple!
If in our environment we have OTRS as a management system and Nagios or Centreon as a monitoring system, we will be able to integrate them and do real wonders, In this first document we will see something very simple: How to monitor the queues we have in OTRS from Nagios or Centreon. And we will continue in the future with other types of integrations!
Very good! This document can be used by all of us who have a Remote Desktop Licensing service in our organization, It will always be good to know how many licenses we consume to analyze future needs or receive alerts in case there are few free licenses left. Therefore, if you have a service of this type in your organization, why not monitor your organization's RDP CAL licenses to avoid problems?
At last, Last document in this super interesting series! Where we can measure the SLA offered by our Business and the time it has been offering service, we will also see how to transfer this Business monitoring to interactive maps with NagVis; in addition to carrying out impact analysis on our Business, where we can analyze the critical points of our business!
What's up txabales!!! How do we usually find out that a DHCP server is down or a scope is full?? Thank you to our dear users, No? As the idea is that our users are the last to notice any problems in our organization (apart from the bosses)… we will take advantage of our monitoring facility based in Nagios or Centreon to control yet another critical point in an organization, DHCP Service!
Part 2! We're going to keep shaping this… Once you more or less have documented on paper or Excel (or however you prefer) this hierarchy of Services that we saw in Part 1 of our Business Service Monitoring, We will therefore proceed with the following, which will be the installation of the Plugin in Nagios, followed by its configuration already in Centreon to be able to use it!
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!
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.
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!
