unable to receive alerts

[bbenichou]

Hi,

First thing first thanks for this great addition to grafana. A simple notification system is exactly what I was looking for.

Anyway I've followed step by step your installation guide but I'm not receiving any notifications. I'm using UBUNTU 14.04 LTS I've set a simple "x>=0" that should fire alerts all the time. I've checked my smtp connection using telnet: no problem. In syslog I can see grafana alerts being launched by the CRON. Here is my alerting conf in Grafana:

In the syslog I get: Jul 3 11:21:01 ubu001-ProLiant-ML110-G5 CRON[19330]: (root) CMD (grafana_alerts) Jul 3 11:21:01 ubu001-ProLiant-ML110-G5 CRON[19329]: (CRON) info (No MTA installed, discarding output)

I've tried to install POSTFIX but grafana-alerts didn't override the sender and recipient and the mail sent was not the notification.

Is there any configuration or specific MTA to use?

Thanks, Ben

Hello

It seems the mail was sent to a local email account called root@ubu001-ProLiant-ML110-G5 in the host where grafana alerts is running. I believe it is a configuration issue. If that is the case: check the values in /etc/grafana_alerts/grafana_alerts.cfg

Modify this properties:

# write a valid email address (for example, your company email address. You can modify it later) _emailfrom = alert@example.com

_# smtp server to use (default value: localhost). Now you are using localhost. # check how the email server is configured or ask for that information. I think# the problem is mails are not being re routed.smtpserver = localhost *# smtp server host to use (default value: 25)

if port is not 25, starts a tls session.

smtp_port* = 25

_# smtp server username to use IF it is needed. Optional. # Leave it commented if not used. (default value: no username) #_smtp_username\ = my_smtp_username

_# smtp server password to use IF it is needed. Optional. #Leave it commented if not used. (default value: no password) #_smtp_password\ = my_smtp_password

Mails should be sent to the right destination.

I checked the syslog more carefully and actually right after Postfix has sent the notification I can see a "removed" trace.

HI @pabloa,

I double checked my grafana_alerts.cfg: everything is set properly and I have no problem to send emails using telnet.

However I believe there is a configuration issue somewhere.

When "POSTFIX" is uninstalled I got the following logs in syslog: Jul 3 11:21:01 ubu001-ProLiant-ML110-G5 CRON[19330]: (root) CMD (grafana_alerts) Jul 3 11:21:01 ubu001-ProLiant-ML110-G5 CRON[19329]: (CRON) info (No MTA installed, discarding output)

When "POSTFIX" is up and running it tries to send an email using "root@ubu001-ProLiant-ML110-G5" and did not take "grafana_alerts.cfg" setting into account.

Should I try another MTA?

Thanks, Ben

I have it running using a postfix server located in other machine . I am using smtp without authentication. I tested it with a Google smtp server and it works too. Based in your feedback I suspect the issue is related perhaps to a different behavior of mail python libraries when a local mail server is used. I will review the docs. Could you please configure it to send emails using a smtp server running in a different machine? Or using Google smtp? Let me know how it goes

Ideally I would like to use a distant windows smtp server or even a Google smtp server.

The thing is on both case - windows and Gmail - it doesn't work and I get (CRON) info (No MTA installed, discarding output) in the syslog. Then if I install a MTA like postfix or sendmail it tries to send the alerts emails from these local smtp server, which is not what I want.

Basically it's like my conf in grafana_alerts.cfg is never taken into account.

I'm surely missing something but can't figure out what.
