NetPing Company issued a regular firmware update for the device NetPing /PWR-220 v3/ETH. A new firmware version allowed to make a work with a device more reliable.

What was changed in the latest version?

The most typical issue of monitoring server rooms is controlling climate and environment while a computer equipment works. Tracking temperature parameters and making a decision on results may be automated.

Let us consider an example of automation for controlling a climate in a server room based on Microsoft PowerShell script.

Syslog (System log) is standard for sending and registering notifications about events taking place in the system (i.e. creating logs), which is used in computer networks, working via an IP protocol. A term «Syslog» is used to name both a standard network protocol Syslog, and software (application, library), which sends/receives system notifications.

NetPing company informs about issuing a firmware update for the device NetPing 4/PWR-220 v4/SMS. A new firmware version for a device allowed to make a work with a device more convenient.

So what has been changed in the latest version?

The NetPing company issued a regular firmware update for the device NetPing /PWR-220 v3/ETH. A new firmware version allowed to make a device operation more reliable.

So what has been changed in the latest version?

In this article, we will describe creating a remote metering system of a consumed electricity built on the basis of a device NetPing IO v2, an electricity meter and a monitoring system PRTG Network Monitor. This system allows to take readings remotely from a pulse output, which may be subsequently sent to a PC.

NetPing company informs about issuing software updates for UniPing server solution v4/SMS and UniPing server solution v3 devices. New versions of software allowed to make the operation of devices more stable and functional.

So what has been changed in the latest versions?

To make a NetPing device located on the LAN available via the Internet, there is a need to configure port forwarding on your router.

Port Forwarding is a technology allowing to access a network device in the internal LAN behind a router from the Internet using NAT technology. The access is made by redirecting traffic from an external address of the router to the address of a selected network device in a local network.

A remote sensor monitoring device UniPing server solution v4/SMS allows to organise an access monitoring system to a server room remotely on the basis of a motion sensor and a door opening sensor. What happens when the sensors are triggered: when a door is opened or a motion is indicated in a server room, a device UniPing server solution v4/SMS can instantly send SMS notifications to a technical staff. Thus, UniPing server solution v4/SMS provides additional security functions to server rooms and other rooms to prevent unauthorized access.

There is a certain moment when businesses grow up to the level when their internal informational systems do not fit a single server cabinet anymore. And then the leader of the IT department has to consider all pros and cons and decide if to build a server room or not. There can be several variants: from getting rid of own capacities totally and moving them to clouds or colocating in a big data center, to building own mini (or not mini) data center with blackjack.

NetPing company prepared a new version of software for NetPing 2/PWR-220 v1/SMS device. New versions of software for devices allow to increase a reliability of devices operation.

Why so?

If a main page, a page "Settings" and a page "Firmware" open normally, but other pages are unavailable, then a probable reason is incorrectly ended last software update. A software update is performed in 2 steps: first, software of a device is updated, then a device will reboot. Afterwards, firmware resources are updated, including a content of web pages. When the first step of software is completed and the second step is not, only several web interface pages remain active. They allow to retry software update process.

To begin with, let us examine what is a regular server room. As a rule, it is a room indoors, often not of a big size, which is sufficient to place server racks with a specific set of network equipment. The most often a server room is in a basement or in an attic. Therefore, a location of a server room is not the first priority to think about for an administration of an organisation.

My name is Marat, as for now I'm an IT specialist in a wide range of areas, almost any-key. In my review I would like to pay a reader's attention to systems of microclimate maintaining and monitoring in a server room.

Recently I faced the issue of providing a workplace for a duty shift as an administration decided to provide a 24/7 support. We employed a necessary amount of administrators who were in charge to do shifts (including nights) and watch an operability of systems.

The following 4 things prompted me to write this article:

1. The article «Why It Is Important to Maintain Temperature Conditions in a Server Room. How a Server Room Cooling Usually Works», where the author tried to fulfill the honorable and very difficult mission of explaining why it is necessary to cool servers.
2. Mistakes found in this article.
3. My own experience.
4. A very small number of rich in content articles on the topic of data center infrastructure (I mean that a server room = a little data center) at Habrahabr. However «Beeline» and guys from "Data Centres Russia" are great in this.

In this article I would like to describe my experience as well as my attitude to monitoring a server room. To start with, let us estimate a scale of a responsibility area. I have a small server room (two square meters), where there are only 2 racks: one for servers and another one for network equipment. A climate is maintained by a split system with two air conditioners (a main and a backup one) and we have a UPS there. In general, it is a typical server room of a small company. Firmware: DELL, NetApp, networks on Cisco, UPS APC, server: ОS Windows Server 2008 R2 (AD, DNS, DHCP, application server and DB server), PRTG Network Monitor is responsible for monitoring.

Crestron is a system of management and automation for homes, offices, schools, hospitals, hotels and other objects. With the help of a module of management of NetPing devices, Crestron can manage a NetPing 2/PWR-220 v3/ETH device (for the moment, only this model is supported).

In this article we will examine Zabbix 2.2 and PRTG Network Monitor 14.3 from the point of view of features of each system and its installing, adjusting and using difficulties.
