Monitoring suhu ruangan melalui NMS




With PRTG Network Monitor you can set up sensors that constantly monitor the availability and performance of important servers and other equipment in the server room.
Furthermore, it is possible to closely monitor environmental factors such as temperature and humidity. Environmental monitoring is an important issue to protect your equipment from damage that is caused by high temperatures, humidity, or other external influences. If something uncommon is detected, PRTG can notify you in several ways (please see Notifications in the user manual).
An extensive monitoring takes place on two levels: On the one hand, you can obtain measurements directly from the servers and on the other hand, you should also consider environmental values measured in your server room.

Monitoring Servers

With more than 150 sensor types, PRTG can obtain many different measurements from the devices in your network, including uptime, bandwidth usage, and performance values.
Additionally, in order to avoid system failures, you can easily monitor servers and other devices to avoid system errors due to overheating and similar health factors. In PRTG there are already some System Health sensors available for various device types, including the following ones:
With these sensor types you can monitor, for example, the current temperature of a device, its thermal status, cooling status, fan status, and many more, depending on the available measurement components. For this concern, PRTG uses the Simple Network Management Protocol (SNMP) or Windows Management Instrumentation (WMI) to get these values.

Monitoring Servers – Steps to Go

You can monitor the system health of your servers the following way:
  • Add the desired device, for example, your HP ProLiant server, to PRTG (e.g., via the button Add Device on a group’s details page). 
  • Then add a corresponding System Health sensor to this device (e.g., via Add Sensor on the device’s details page). 
  • The channels showing the desired information will be created automatically at run-time, depending on the available measurements reported by your devices, for example, temperatures.
PRTG will begin to monitor the selected device a few seconds later. With PRTG’s pre-defined limits, for example, for temperatures, you will get warnings immediately if a critical threshold is breached. Of course, you can set limits according to your preferences.

Monitoring the Server Room or Data Center

It is not only possible to monitor a server itself. There are also a lot of environmental monitoring possibilities out there. With specific SNMP-enabled hardware sensors in combination with PRTG you can even monitor factors like temperature of environment, humidity, water leaks and floods, fire and smoke, brightness, open and closed doors or windows, as well as other potentially harmful data center conditions. In general, they all work the same way together with PRTG: using SNMP. 
Following are listed some hardware devices for environmental monitoring which we have tested successfully in our labs:
All of these vendors offer physical sensors which can provide data about their environment. Connected to some kind of SNMP-enabled “management box” these sensors become network-enabled.
The manufacturers usually provide Management Information Base (MIB) files for their devices. Basically, a MIB is a text file defining all searchable SNMP objects of a certain device. It includes at least one Object Identifier (OID) defining an unique address and name, and gives further information on the respective object. With our MIB Importer you can import the MIBs of the measurement devices into PRTG. 

Monitoring Server Room – Steps to Go

To use one of the devices listed above for environmental monitoring with PRTG, do the following:
  • Make sure you have converted the needed MIBs to OIDLIB files and saved them in the snmplibs sub folder of your PRTG program directory
In the context menu of a group or probe, choose Add Device… to add a device to PRTG which represents your measurement device: 
  • Type in a suitable name (e.g., PCMessure) and use the device’s IP address in the settings. You can leave the other settings unchanged. 
  • Then click on Add Sensor on the device’s details page and select the sensor SNMP Library (to find it easier, filter for SNMP as used technology) with Add This
  • A popup will appear where available library files are listed. Choose the library that you have created from the MIB and confirm with Ok
  • Then choose the sensors you want to monitor by clicking on the corresponding check boxes and confirm it. PRTG will usually create several sensors, one for each individual OID.
Now you are able to monitor the environment of your devices, for example, in your server room. PRTG will start to monitor the sensors of your measurement device immediately and will alert you if it is necessary.

  1. You can monitor any network by using nagios or total network monitor, you can find guides about using these software in internet, it's not hard.

Timer AC bergantian

Bagaimana sich prinsip kerja AC yang bergantian? Seperti yang terangkai pada ACPDB, yang kita butuhkan adalah 1 buah timer dan 2 buah kontaktor. Pada dasarnya rangkaiannya adalah seperti gambar diatas. Seperti kita ketahui, timer dan kontaktor akan bekerja apabila mendapatkan catuan 220 V. Pada timer catuan bisa dikoneksikan di lubang “L” dan “N”, sedang pada kontaktor dilubang “A1” dan “A2”. Itulah kenapa pada saat mati listrik komponen2 tersebut tidak bekerja. Timer berfungsi sebagai switch dari 2-1 atau 2-3 dan lubang “2” sebagai sumber yang dialiri arus listrik. Sesuai namanya alat ini akan bergantian dari 2-1 atau 2-3 berdasarkan waktu yang sudah kita atur pada sirip biru. Satu sirip merepresentasikan 30 menit. Sedang pada kontaktor untuk tipe Telemecanique, sumbu-sumbu saklarnya adalah 1-2, 3-4, 5-6, NO-NO, NC-NC.  Jika “A1” dan “A2” tidak dicatu maka 1-2 (open), 3-4 (open), 5-6 (open), NO-NO (open), NC-NC (close/terhubung). Dan bila “A1” dan “A2” dicatu  maka 1-2 (close), 3-4 (clo…

1.1.Area Data Center
Areadata center termasuk aset vital perusahaan dan diperlakukan sesuai dengan persyaratan yang telah ditetapkan dalam Sistem Manajemen Pengamanan Perusahaan.

Seksi Jaringan bertanggungjawab terhadap pengamanan fisik dan logik. sedangkan fungsi Sekuriti terhadap pengamanan fisik.


1.2.Pertimbangan Dalam Hal Penentuan Lokasi Area Data Center
Beberapa pertimbangan yang harus ada dalam menentukan lokasi ruang data center, yaitu :

1.Memungkinkan untuk pengembangan yang memadai, misalnya mempertimbangkan pengembangan untuk jangka waktu 5 (lima) tahun ke depan.
2.Mempertimbangkan ruang yang tidak "terlalu” banyak dilalui untuk operasional lain, namun tetap dapat dijangkau dengan mudah.
3.Memperhatikan aspek keamanan dan keselamatan pekerja.
4.Memenuhi persyaratan sebagaimana yang …

Mendesigns dan Menghitung UPS untuk Data Center

Mendesigns dan Menghitung UPS untuk Data Center UPS dan data center mungkin bisa di sebut sayur tanpa garam, hambar jika tidak saling melengkapi. 
Tapi untuk menentukan kebutuhan akan UPS data centerperlu perhitungan yang matang agar UPS dan server tetap awet dan selalu ON 24 jam. banyak sekali jenis UPS dan daya yang di tawarkan. Kita harus menghitung kebutuhan beban keseluruhan server agar ketika listrik down UPS dapat menghandle beberapa detik untuk listrik pindah ke genset begitu pula sebaliknya, Oke untuk menentukan itu semua tentukan dulu jenis UPS yang akan anda gunakan.
Oke kita sedikit belajar dulu tentang UPS :)
PRINSIP KERJA UPS Setiap PC membutuhkan daya listrik. Apabila aliran listrik (main power) terputus, PC akan mati (tidak berfungsi). Fungsi dasar UPS (Uninterruptible Power Supply) adalah menyediakan suplai listrik SEMENTARA ke beban (PC) tanpa terputus pada saat main power tidak bekerja agar seluruh proses dapat dihentikan dengan benar, seluruh data dapat disimpan den…
