Question for the Xymon list:
What have you used, other than email-to-sms/mms gateway, to send xymon alerts to cell phones? I've been hit a few times with unreliable email to mms gateway (TMobile). I know about pushover.net. Are there any others?
Hello Glauber,
I read this as you're seaching for a more reliable solution than sending E- Mails to a remote E-Mail-to-SMS Gateway.
Since it makes less sense to send alerts for network/internet is broken via internet, we needed an other solution. We're operating a wide area network and the xymon of course should alert us about network issues.
We are running SMS-Gateways directly attached to the Bigbrother/Hobbit/Xymon- Servers for a very long time. The vendor of both of our modems is MOXA, but it's of course a much older model than this one: http://www.moxa.com/product/OnCell_G2111.htm
But the specs haven't changed much from the first look. Today there are also some other vendors.
This takes a SIM-Card like a mobile phone, and is moutet to DIN-Rail, were also the external switching-powersupply is located.
On the Xymon-Servers we're running the smsd from the smstools provided by http://smstools3.kekekasvi.com. Since the Server is a Ubuntu they're already available as a package. We are running this as an E-Mail-to-SMS-Gateway more or less for historical reasons, or because we've some other Systems using this as E-Mail-to-SMS- Gateway, choose one. We're running this as with a Script that is plugged into postfix as pipe-Script (perl-Script), but it would be also possible to let an Xymon-Alert-Script drop the SMS into the smsd-queue. Writing a file into a specific folder with some specific headers isn't really rocket science. ;-)
We're using this for about 12 years with the smstools, now. And some years with a Tobit-Server in between, before.
For one of the xymon servers, we needed to get out of the ferrocroncrete cellar rooms, where no mobile phone works, to get the modem work realible.
One thing you should also consider is, that SMS-Flatrates are (nearly) always shipped with a clause prohibidding the use for SMS-Gateways. On other contracts this is not so wide spread. So read the contract you are using for this carefully. This might affect the realibility of the alerts. On the other hand you should have a look at the amount of send SMS carefully. Multipart SMSes might also increase expenses, but the smstools allow to deactivate them. ;-) :-)
This is not really a solution for sending huge amounts of SMSes (mainly because of the costs), but it's a highly independent way to send alerts. We are using 2 modems, one attached to each xymon server.
Kind regards, Lars
