The use of removable storage devices is usually not allowed in organizations, you should not at least be able to connect a USB flash drive or removable hard drives. But it is true that in exceptions, They are needed, and for this purpose a GPO is usually defined with a whitelist of allowed USB devices and applied to the users/computers that need them. But ,How do you use them??
I had been waiting for a long time to publish some posts about Telegraf and some wonders we can do. In this simple document we will see how we can collect performance metrics from a Raspberry Pi and display them in real time with Grafana!
If we have an HP server in the organization and we want to monitor it with Centreon, Nagios or similar, In this post you will find the steps to know the state of your health, of the hardware (Disks, RAID, Power Supplies, ventilators…) and any components, as well as knowing the temperatures of each sensor.
At the gates of summer, what better than to have a relaxed chat with my colleague Federico Cinalli, This time it's time to talk about storage in general, We will take a look at the solutions we have today from the retro era. We will talk of course about disks and software, of its evolution and the options that we can find; all aimed at any market, From small environments to critical environments, where in addition to good performance high availability is necessary.
If we still want to exploit our Nextcloud installation more and we want to know how much each user is consuming… This is your post! It's going to look great because we're going to see it directly from our Grafana!
Another stroke of genius that we can do with Nextcloud is the possibility of presenting external storage and mounting it to give access to our users directly. GOOD, What do we mean by external storage?? Well, for example, What we'll do in this post, which will be to connect some shared folders of a Windows file server,
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!
If we are interested in controlling the load on the disks of our Windows servers, we will be able to monitor it simply thanks to a simple PowerShell that we will run through NRPE. We will obtain read and write latencies, Number of reads and writes per second, as well as the read and write ratio in MB/s and also the read queue time & writing!
In this document we will start with something easy, we are going to monitor our first Windows computer, whether it is a Desktop or a Server. We will monitor the basics through SNMP, be CPU usage, RAM, Disk, Net, Swap Memory and Ping. With this we will have a first base to then add more elements that we need to monitor!!!
I leave you this post because a client has asked me to do it on several occasions and so I leave it for you 😉 too If we need to expand a virtual hard drive (Vhd) that is shared across multiple virtual machines, typically for cluster use, we will remember that we have the SCSI controller in Bus Sharing and that the disk is created in Eager Zeroed! We will follow these steps to expand this album.
