Event monitoring systems make understaffed data centers run smoother
According to Symantec’s latest “State of the Data Center” report, which was released early last week, half of all IT executives say their data centers are extremely understaffed. With the economy still struggling to get moving again, it is no wonder that network engineers and facility managers are having to find new ways to get the most out of their stagnant or shrinking staff and resources.
Less staff means more remote monitoring for many organizations. Having a remote monitoring system, like the SecurityProbe, can help lighten the load of working with less. With a price point that usually falls below $2,000 for a complete system, it can mean a considerable savings over staffing each location, or even worse, not monitoring it all. In this scenario, one person can monitor the well-being of several locations.
Top 3 advantages of web-based temperature monitoring systems
Filed under: environmental monitoring, humidity monitoring, temperature monitoring
It regularly occurs to me that web-based environmental monitoring systems, whether they be for the home, office, data center, storage closet, you name it, can oftentimes be overkill. Some people just need a thermometer. Others just need a barometer. Sometimes, simple problems call for simple solutions.
However, a web-based system that can monitor for changes in temperature, humidity, airflow, as well as the presence of water, smoke and motion, can be extremely valuable. To demonstrate just how valuable, I thought I would put together a list of the top three reason why a web-based system is more convenient and cost effect for many home and business applications.
What you can do about Christmas tree fire hazards
Filed under: Security Monitoring, smoke detector, temperature monitoring
The holiday season is finally upon us. As usual, with the cold weather comes turkey dinner and Black Friday sales - but that’s not all! If your family is anything like mine, the first thing you do after properly digesting your stuffing and waking from your Tryptophan coma is put up that glorious Christmas tree. There is really no better indication of the impending holiday season than a well lit and beautifully decorated tree.
I am a fan of the good ol’ fashion fake tree. Nothing says Happy Holiday’s like the smell of, well… plastic. But as I understand it, there are some 33 million American homes that go the natural route with their tree selection. However, improperly hydrated Christmas trees can pose a very real safety concern. According to the U.S. Fire Administration, “Christmas trees account for 200 fires annually, resulting in 6 deaths, 25 injuries and more than $6 million in property damage.”
Temperature monitoring during the winter months
Filed under: Intelligent Sensors, environmental monitoring, temperature monitoring
With winter just around the corner, those of us in the more northern locations (the Ravica offices are located in Southern Maine) begin preparing for cold temperatures in a variety of ways. Whether you’re just sealing the windows to keep the cold air outside, where it belongs, or selling all of your most prized possessions on Ebay to cover the home heating costs for the impending months, it is important to get a jump on these preparations.
Water leak detection systems in the server room
Filed under: environmental monitoring, water leak monitoring
With the importance placed on temperature and humidity monitoring and detecting hotspots in the data center, it is easy to forget that the second most common cause of catastrophic failure are water leaks. Whether your server room is located near refrigeration equipment used for building cooling, building facilities like bathrooms and kitchens or air conditioning units, precautions need to be taken.
Prevention
It all starts at the building planning level. Having an initial survey, to know if your building is in or near a flood zone, sounds like a no brainer, but it’s surprising how many people I speak with on a weekly basis that are in the heart of a flood zone with no water monitoring system in place. Once you know the situation your server room is in, it is important to take the necessary precautions by having the proper drainage installed, including a sump pump. This protects you in the event flooding becomes present.
Minimize network downtime by monitoring temperature in the data room
Filed under: Data Center, environmental monitoring, humidity monitoring, temperature monitoring
Infrastructure stability is constantly at the forefront of network planning and management. A good data center needs to be well organized and structured for clean operations, but it also needs to be appropriately optimized to guard against environmental disasters. Now, when I say disasters, I don’t necessarily mean typhoons and earthquakes. Even something as simple as an air conditioner losing power and the temperature rising to dangerous levels could be a disaster.
While a building management system can help optimize air flow and lower temperatures, they are not fail proof. That’s where Ravica comes in. Ravica provides some of the largest companies, with the most complex data centers, with solutions that ensure the integrity of environmental conditions within the data room. Not only can our intelligent temperature and humidity sensors tell you when conditions have become hazardous to your equipment, but our SensorProbes can take action as well.
How to reduce false positives and frequent temperature alerts
Filed under: Data Center, SensorProbes, environmental monitoring, temperature monitoring
Previously, I wrote about managing the sensitivity of your motion detector to prevent or reduce false positives from normal environmental motion, while maintaining the security that the motion detector sensor provides. I thought I would elaborate on the subject by providing some tips on how to limit frequent alerts and false positives for any environmental monitoring sensor, like temperature.
As I mentioned before, the “continuous time to report,” or “rearm” as it is called on the SecurityProbe, are an excellent way to say, “Don’t alert me as soon as a sensor goes into a ‘warning’ or ‘critical’ status. However, if it has been in a ‘warning’ state for 30 seconds, let me know.”
Another way to limit how often – or how easily – your BitSight2 or SecurityProbe sends you Skype alerts or emails is to adjust the “reading offset” field, which can be found under each sensor’s advanced settings. The “reading offset” forces the sensor’s reading to move over or under a certainly value before generating an alarm. So basically, if your temperature upper “warning” threshold is set to 80 degrees and your “reading offset” is set to 2, and the current temperature is 79 degrees, then your SensorProbe will not alarm until the temperature drops another degree.
This prohibits the sensor from being right on the verge of a threshold and consistently bouncing between two statuses. You don’t want 20 emails in your inbox because the temperature in your data center is exactly on your threshold and wobbling back forth between “normal” and “warning.”
Another way of limiting alerts during off hours, maintenance windows or times when you are not really concerned with the readings breaching a threshold is to use the calendar feature. Please note that the calendar feature is available only on the SecurityProbe line of SensorProbes.
Block off times that you do not wish to receive alerts and the SecurityProbe will ignore the breached thresholds during those time frames. Perhaps you don’t want to receive alerts during the day, because people are always present and aware of the environmental conditions in the locations you are monitoring. However, maybe you want the temperature of your walk-in cooler monitored at night, when no one is in the building.
Whatever the reason, these are two great tips for better managing your alarms. This ensures that your alarms are more meaningful and so when you or you staff see an alert from your BitSight2 or SecurityProbe, you know it is time to act.

The importance of monitoring airflow in the office
In a previous blog, Mike mentioned the importance of monitoring the airflow in your data center, but recently we were reminded of just how important airflow is in the work environment. Normally, our office is quite chilly. However, yesterday, the employees of Ravica were treated to nice a nice toasty office to work in. It was certainly a welcome change.
The reason for our cubicles being so nice and warm was because the air conditioning (which is normally blasting non-stop) was not turning on. After several hours, the nice toasty office become a stagnant bog of stale air. Breathing nothing but other people’s CO2 was getting my coworkers and I very sluggish and lethargic – not to mention hot and sweaty.
Luckily, we had a couple of airflow sensors placed in front of the air conditioning vents. As I mentioned, the air conditioning in our work area is typically blowing all day, and quite hard, so to have it shut off for a while and let the office temperature rise a bit, is actually a good thing. However, we can now see that if it does not start back up in a reasonable time frame, things can go too far in the other direction.
To alleviate the issue of getting email alerts from the airflow sensor every time the air conditioning unit shut off, we tweaked the “Continuous time to report” field, under that sensor’s setup screen. Now we can occasionally get a reprieve from our normally frigid conditions, but if the air conditioner stays off for more than a couple of hours, the building manager and our office manager get an email alert. Of course, since we have the airflow sensor connected to a SecurityProbe, we can use escalated notifications. So if for any reason the building manager does not acknowledge the alert within an hour, then he gets a text message sent directly to his phone.
So it is certainly important to keep your expensive data room equipment from overheating, but it is just as important to keep your employees from overheating as well.

Help desk: How sensitive is your motion detector sensor?
Recently, I blogged about using the motion detector sensor to increase the security presence of your data center. Well, expanding on the topic, I thought I would answer one of those frequently asked questions I get from customers using the motion detector to beef up security. “How do I keep the motion sensor from being set off by very small movements?” The answer – you can adjust the sensitivity of the motion detector using the sensor status filter.
The sensor status filter allows you to enter a time delay that must occur before the sensor changes status, thus filtering out noise in the signal. This avoids unnecessary sending of notifications, as fluctuations can occur during normal working conditions.
To find this setting, go to the Motion Sensor Settings page of the web interface, and click on the sensor status filters button. Change the “Continuous time (secs) sensor is to report” field to some value other than zero. 1 second is a good place to start, but it all depends on your specific working conditions.
At any rate, increasing the continuous time to report field a bit can help keep you from getting false positives and give a little extra room for normal environmental shifts.
Stay tuned to the Ravica blog for more helpful environmental monitoring tips.

Motion detector sensors add security to your data center
Filed under: Security Monitoring, environmental monitoring, motion detector
While working on a project recently, I was taught the importance of the motion detector sensor in the security monitoring toolset. The SecurityProbe is the first place to look for monitoring the temperature, humidity and other environmental variables of your server room, while at the same time adding a security presence with the pan-tilt dome camera support. However, for some customers with smaller or unconventional data centers, the budget for security and environmental monitoring can be in the hundreds of dollars, not thousands.
That’s where the motion detector comes in. It works not only with the SecurityProbe line, but with the BitSight2 and BitSight8 as well. The beauty of the motion detector sensor is that you can daisy chain up to 10 sensors to work off a single intelligent sensor port. And at just $125 per sensor, users can easily cover a good sized data room with motion detection and still have an extra intelligent sensor port on even a BitSight2 for monitoring temperature and humidity.
So keep the motion detector sensor in mind when speccing out a new data room or when adding security monitoring measures to an existing one. It is a very affordable alternative, when it is simply not possible to have eyes and ears on your secure locations.
