Default Java-monitor introduces SMS notification, gives free SMS notification credits

Dear All,

Java-monitor is giving away free SMS notification credits as an introductory offer.

We have just updated Java-monitor with its new SMS notification feature. You can now be kept up-to-date about the status of your servers, even when you are on the road and your e-mail is inaccessible.

Every active Java-monitor user will receive SMS notification credits. This way you can get started immediately and try out the new SMS service for free. New users who register before the end of September 2009 will also receive free SMS credits when they start monitoring hosts with Java-monitor.

As most of you know, our e-mail notifications already include information such as memory use and restart times. The SMS notifications cram a condensed version of this analysis into the 160 characters available. This makes the SMS notification messages more than just an "it's dead"--message. By reading the SMS notification messages, you will know when the server was last restarted and what the memory use was when it stopped sending data to Java-monitor.

Here is a screenshot of a telephone demonstrating the use of SMS messages. From the first, OFF-LINE message, we can see that our memory use was fairly normal. In the second, ON-LINE message, we see that the JVM was restarted mere seconds before the first data arrived at Java-monitor's collector servers. This probably means the JVM was restarted between the time it went off-line and came back on-line.


The screenshot shows a third message. This message lets us know that our SMS credit has run out. Java-monitor automatically lets you know via e-mail when you SMS credit is about to run out. When the last SMS credit was used up, we send you an SMS message warning you that you will not receive additional SMS messages until you have purchased new credit. Just in case you are on the road when this happens. Obviously, that service announcement is sent free of charge.

If you would like to get started with SMS notifications, simply log into Java-monitor and open the host for which you would like to enable SMS notifications, as shown in the screenshot below.


You will be prompted to enter and validate your mobile phone number. We want to be sure we're notifying the right person, of course. :-) Here is a screenshot of what that looks like. Just enter your phone number and press the "Send Validation Code" button.






You'll get a message on your phone with a code. Enter that code in the Validation code box. That's it. You are now all set to receive the notifications on your mobile phone.

I would like to say 'thank you' to users Barry, Kees de Kooter, admini and lethyro85 for beta testing. They have received 100 SMS credits for their effort. Thanks guys, for showing patience when I broke the test environment (again).

We hope you find SMS notifications a useful feature.

Kees Jan

PS. Oh, I almost forgot. In the same release, we have added a mechanism to avoid sending out false positives in case of Java-monitor server failure. We are now using distributed watchdogs to ping the main site regularly from several locations. This makes it easy for us to differentiate between a local network failure near the Java-monitor servers, or a network failure on the monitored host's end. With this system false positives should be a thing of the past.

PPS. Did you know that Java-monitor will be featured on the TheServerSideSymposium 2009? Find out more on http://javasymposium.techtarget.com/...JKosterMonitor. Hope to see you there.

Dear tanyehzheng,

Our SMS provider charges us a certain fee per SMS per country. We just flatten that out so that for Java-monitor you need one Java-monitor SMS credit per host up/host down message you receive. That is regardless of country or operator you are on.

The SMS-credit-is-running-low warnings are free of charge for you.

Does that answer your question?

Kees Jan
