SMS Notification Delays

[aastaguy]

Hello,

I am experiencing hours of delay when I try to validate users' cell phone numbers in Nagios XI. Since the key expires after 10 minutes, nobody can validate their phone number. Additionally, I have my cell phone number validated and have started experiencing hours long delays on SMS notifications sent for monitored hosts and services. Has anyone else had this happen and have a solution?

So far, all of the cell phones are Verizon based, I have tried [email protected], and [email protected] and no luck on either.

Thank you for your help!

@aastaguy, If you send a regular email to [email protected], how long does it take to receive a text message? What version of XI are you currently running?
Do you also have email notifications set up on the XI? Are email notifications experiencing any delays or not?
Are you using SMTP server?

@npolovenko, thanks for the reply, I forgot to mention that.

If I send an email, with [email protected], I get it instantly. I am running XI 5.6.1, but it did not work in the previous version before that either. I upgraded to 5.6.1 to see if it had any effect. I do have email notifications setup and I receive those quickly as well.

Thanks, and please let me know if you need anything else.

@aastaguy, Can you go to the SMS Notification Preferences Menu and take a screenshot?

Also, could you send in your Nagios XI System Profile so I can review it?
To send us your system profile. Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button
Save the profile.zip file and send it to me in a private message.

Thanks for the reply, attached is the screenshot of the nagiosadmin account preferences. I am trying to enable the SMS notifications on other accounts, and not the nagios admin account, so let me know if you need anything else for that. I can't click "enable notifications" on the mobile tab until I verify the phone number on the account I want to set it up for, which is the SMS message that takes up to 24 hours to receive.

I will send you my system config here shortly in a PM.

Thanks,

Ryan

@aastaguy, Please open the Mobile Carriers page and take a screenshot.

Are you using sendmail or SMTP for mail notifications?

Try enabling the debugging option and when you send an SMS verification code tail:

tail -f /usr/local/nagiosxi/tmp/phpmailer.log

And:

tail -f /var/log/maillog

The problem is most likely caused either by a) your mail server not accepting specific emails or b) some phone carriers can be blocking these kinds of emails or taking a long time to respond when their servers are backlogged.

OK, I will have to debug tomorrow, but I found out that an AT&T phone number verifies promptly. It seems it may be the latter of your thoughts with the cell carrier.

My Mobile settings look the same as yours, and we use smtp. Does this seem reasonable? We have our server name and port 25 for the SMTP settings.

Thank you for all of your help so far!

That looks correct for AT&T

as for the SMTP port and settings, it all depends on your SMTP servers requirements

[aastaguy]

Yeah, AT&T worked great, but Verizon's %number%@vtext.com or %number%@vzwpix.com are the one's getting delayed. I am debugging my mail server at the same time we are troubleshooting this from the nagios side. But if I send an email from outlook to either of the Verizon accounts above, it works great.

Thanks.

Weird, it would be interesting to see the SMTP server logs for messages being sent to either of those addresses to see if Verizon is forcing the delay, or if they are being accepted by Verizon and then delayed.
