[SOLVED] No email sent when a threshold is reached

[mikygee]

Hello,

I'm trying to get email sent when a value reach a certain number. In my case it's the number of nat sessions (let's say 10000).
I'm probably missing one step because emails are never sent.

Settings:
1) It's installed and enabled in Plugin Management
2) In Utilities > User Management I selected Send Test Email for my user
3) I installed settings and I receive an email when I select "send a test email" in Configuration > Settings > Mail/DNS
I think Settings is working just fine

Thold:
4) It's installed and enabled in Plugin Management
5) In Utilities > User Management I selected Configure Threshold Templates, Configure Thresholds, Manage Notification Lists, View Thresholds for my user
6) I created a list in Management > Notification Lists a list called "Test" and specified on mail address
7) I created one threshold alarm called "FW1 Sessions", Threshold Enabled is enabled, Threshold Type=High/Low Values, Re-Alert Cycle=1 minute, Warning High Threshold=9990, High Threshold=10000, for both of them Breach Duration=1mn, Warning Notification List and Alert Notification List and set with the list name "Test"
8.) If I select Management > Thresholds after some time i see that the line is red

Code: Select all

FW1 Sessions 	High/Low 	10000 	2000 	1 Minute 		Every Minute 	14826 	yes 	Enabled

Email is never received in my mailbox
9) When i look at /var/log/maillog I see when the test email is sent with Configuration > Settings > Mail/DNS / Send Test Email but nothing when Thold should send the email
10) In the logs I see messages such as

Code: Select all

12/04/2011 11:41:07 AM - Threshold Breached ID: 1 DataTemplate: FW1 Sessions - 5 Minute Sessions DataSource: 5min_sessions Type: High/Low Enabled: on Current: 14826 High: 10000 Low: 2000 Trigger: 1 Minute Warning High: 9990 Warning Low: 3000 Warning Trigger: 1 Minute SentTo: myemail@isp.com
12/04/2011 11:41:07 AM - THOLD: Sending email to 'myemail@isp.com'
12/04/2011 11:41:06 AM - THOLD: Preparing to send email
12/04/2011 11:41:06 AM - THOLD: Alerting is necessary

I looks that Thold is at least trying to send the email but I don't know why it's never sent

What version of thold? Also, check the syslog and maillog on the Cacti server. Could be spam as well.

Hello,

Thank you for your answer.

I use cacti 0.8.7h and weathermap 0.97a

I don't send anything on the syslog
Settings > Cacti Settings > Log File Destination = Logfile Only
Do you mean that I should set this to Logfile and Syslog/Eventlog ?

What do you mean by maillog on the Cacti server ?
In step 9) I checked /var/log/maillog

I did more tests and found out in Configuration > Settings > Mail/DNS that when Mail Services is set to:
- PHP Mail() function => it doesn't work
- Sendmail => it doesn't work
- SMTP => it works

When I posted my first message I was using PHP Mail() function and the test message works but Thold doesn't.
From the begining I had configured in php.ini

Code: Select all

sendmail_path = "/bin/sendmail -t"

Could you also explain me what is the difference between Sendmail and SMTP.

Thank you

SMTP is a low level PHP Emulation level for 'sendmail'. It bypasses the os entirely. Yes, by log, I mean the mail and syslog for send errors. So, is the problem fixed?

Hello again,

I solved my problem just after writing my last message.
Writing the message helped my to find the solution.

I use two different php.ini. One is used by Apache, one by the poller.
When I pressed "send a test email" in Configuration > Settings > Mail/DNS, the Apache php.ini was used and that one was properly configured.
When the poller tried to send an email, the other php.ini was used and I didn't configured it to send emails.

Why I have two php.ini ? It's because I run Cacti on my OpenBSD OS with Apache chrooted. I will improve the installation when I'll upgrade my OpenBSD but I'll probably keep two different php.ini.

Thank you for reading my messages and sorry for the question, I searched a lot before writting. The most difficult with installing Thold, is not the plugin itself but the system configuration that is around it.

Have a nice day
