Dew Point Calculator on

On our website we have added a new tool: dew point calculator.

The dew point is an important metric to watch in data centers & server rooms as it is the temperature at which water turns from vapor into liquid.    This can cause short circuits on equipment, like Facebook experienced in its Prineville data center.

The calculator takes 2 inputs: temperature and humidity.  Based on those readings it computes the dew point and compares it to the limits as defined in the ASHRAE standards.  

The calculator can be found on following url:

Expansion unit for the SensorGateway

We released the SensorHub, an expansion unit for the SensorGateway.

The SensorGateway is the base unit for our environmental monitoring solution.  It comes with a built-in temperature monitoring sensor.   The device can host up to 2 optional external sensor probes such as temperature, temperature & humidity, flooding, power failure, airflow, shock, dry contact.

The newly launched SensorHub connects to the SensorGateway and allows for the monitoring of 8 external sensor probes instead of 2.

Next to the additional ports for external sensor probes, the device also includes 4 dry contacts inputs, 2 dry contact outputs and 2 relay outputs.

You can find more information about the SensorHub on

Beyond Data Centers & Server Rooms

When we started selling our first generation of temperature sensors and other environmental sensors back in 2004, we tied our sensors closely with our Monitoring Software which was launched a year earlier.

The sensors relied on a proprietary serial protocol and couldn't be integrated with any other network monitoring software.

This changed in 2010 when we launched the first generation of our Sensorgateways.  The Sensorgateway was created as a low-cost but high value IP based temperature sensor.   The idea was to create a device that would be able on its own to monitor, report and alert on sensor values.

As no software was needed to control the sensors, customers started deploying our sensors beyond the data centers and server rooms we designed them for.   Our industrial design made them suitable for other industries that we didn't think of and that our customers found applications for.

To illustrate some of those industries we created a small video that shows you how our sensors can be used in data centers, server rooms, healthcare, cold storage, oil & gas, communication rooms, winery's.

If you have deployed the sensors in other fields than above, then please share in the comments section how you use our sensors.  If  you have a nice high resolution picture, then we will see if we can include it in the animation.

ServersCheck launches at CeBIT Australia its new generation of wireless sensors for server rooms & data centers

At this week's CeBIT 2013, ServersCheck launches with its distributor, Duons Australia, a new generation of probes: the “wireless temperature probes”.

Best practices recommend to monitor the temperature inside a rack in 3 different spots. This can be achieved with 2 external temperature probes connected to a SensorGateway, which also has its built-in temperature sensor.

However, thanks to the new wireless sensor, one SensorGateway can now control up to 30 wireless temperature sensors, or 10 racks.

A wireless temperature sensor can monitor temperature between -10 °C to + 85°C with an accuracy of 0.5 °C. A wireless sensor requires no configuration: once powered it automatically connects to the wireless base station. Wireless sensors have a battery life of one year.

Wireless Offers Significant Advantages
• The ServersCheck wireless temperature sensor is more compact compared to traditional wired temperature sensors and therefore easier to install with the use of magnets.
• No wiring is needed, simplifying the installation, requiring less labor and speeding up implementation.
• The shortage of IP addresses or their cost may hinder the deployment of conventional wired probes. With these wireless sensors, only one IP address per 30 probes is needed.

Depending on regulatory approval, the wireless sensors are expected to be available at the end of Q3 2013.

BlueSky Samoa: ServersCheck and Huawei

 Bluesky is a mobile telecom operator active in Samoa and American Samoa. It is the third operator in the Pacific to go live with our solutions for monitoring mobile base stations (cell sites) from our sister company, BTS Monitoring.   BTS Monitoring has developed a series of sensors compatible with the ServersCheck Sensorgateway that are especially designed to monitor mobile networks and cell towers.  You can find more information about BTS Monitoring on

The launching customers for our cell site monitoring solution in the Pacific were OPT New Caledonia and Norfolk Telecom.  

The solution implemented for Bluesky Samoa was installed inside Huawei manufactured outdoor cell sites.  The implementation was done together with our Australia & Pacific Rim partner, Duons Australia.

The solution consists of:
1) a ServersCheck sensorgateway allowing for monitoring environmental conditions inside the outdoor cell site.  Temperature in tropic countries like Samoa may pose a problem for cell sites as the equipment, such as the one from Huawei, has to operate below a maximum operating temperature of 60°C (or 140°F)

2) the BTS Monitoring Quality of Service sensor probe.  This sensor monitors non-stop the availability and performance of mobile services from an end-user perspective for signal strength (RSSI), call completion, SMS roundtrip time and data.  It monitors it for both 2G and 3G networks.

The first cell site of Bluesky Samoa to be deployed with our gear was the cell site on top of the Tui Atua Tupua Tamasese Efi office building in Apia, Samoa. 

The cell site is an outdoor Huawei 3G cell tower consisting of a 19" rack with half of the rack made of a battery bank and top half consisting of telecom equipment.  With its 0U design, the orange ServersCheck and BTS Monitoring unit easily integrates within the outdoor cell site.  The units are connected through the Cisco switch with the NOC.

Environmental Monitoring explained in a whiteboard video

Anyone at ServersCheck knows how difficult it can be informing customers about environmental monitoring and the threats related to it.

Too often we see customers getting a configuration that will provide them with a false sense of protection.  Environmental monitoring is much more than just checking if the AC unit is on or off. 

To address this we had designed a DCIM solution brief which includes best practices and tips.

But let's be honest, reading a document can be boring, especially when it's technical.  So we had to find a way to bring the message across in a nice way where you can sit back and relax while we explain it to you: a video.

Sit back, relax and enjoy the 3 minutes video on environmental monitoring with ServersCheck :-)

Sharing monitoring status with your internal and external users

The purpose of a monitoring tool like ServersCheck is monitor and alert you when infrastructure, network, server or application issues are detected so that you can quickly resolve them.

Users start calling you when they experience an issue because you are the expert in your organization in that field.  With a good monitoring tool in place, you already know that there is a problem.  Rather than answering the phone calls of users, you want to focus on the issue at hand and resolve it.

A way to address that communication issue is by sharing the monitoring status in a user friendly way with your internal and / or external user base.

Often system administrators look at ways to have a multi-user monitoring platform so that read-only users can directly connect to the system see the status.   There are 2 major downsides of such a strategy:
1) first of all it is complex to understand for non technical users so giving them access to a monitoring platform won't really help them.
2) second issue is a more critical one: security.  Having different login credentials to a critical platform like a monitoring software is bad security.  Users might be tempted to try on different username / password combinations - who knows maybe it works.  It also opens up the platform to the outside world.

Network Monitoring tools like ServersCheck address that issue by following a double approach:
1) make data available in an user friendly way so that non technical users can understand where the problem is
2) make it available in a location that for them is easy to understand.

Let's illustrate above with the way we deployed it at ServersCheck.  As part of our monitoring software and sensors we offer a SMS alerting service that allows devices to connect to our systems and send out SMS alerts to users.  We monitor our network & system's availability and performance through our Monitoring Software running on a dedicated server with WLAN access to our different offices.  The data relevant to our user community is updated every minute on a dedicated website:   We link from every page on our websites to the status page so that a user can immediately check if one of our online properties has a service issue.  When a user experiences a problem then he can immediately check the status page.  While he looks at it, he knows we know and that we are working on it.

SensorGateways v5 launched

Today we have released the latest version of our SensorGateways.

This fifth hardware generation boasts a set of new exciting features.   The main new feature is the "social monitoring" capability.

SNMP & IP temperature sensors are available from a wide range of vendors, including ServersCheck.  The more advanced, like ours, all feature an embedded web server which allows you to connect to the device and walk around to see the readings of the sensors.

But what when you walk around in a data center or server room and you want to see the actual temperature?  You don't want to have to connect to the sensor to get the reading.  You want to know it right away.

To address this feature we have introduced the OLED display on our SensorGateways.   The oled display shows you in real time the actual readings from the sensors so that you know what's happening in your server room. 

The SensorGateways also have a new firmware on there which makes them compatible with hardware version 3 of SNMP for enhanced security.

The units can also now send out alerts via secure email protocols like the ones from Gmail.
