Configure Netxms to use Gmail 

Hi all,

I have the following servers:

1- Server A , 172.16.16.82 ( here , i installed postfix and Netxms server )
2- Server B,172.16.16.86 ( here ,i installed the Netxms agent )

currently I would like to send an e-mail alerts from my gmail account to a list of recipients. So , I did the following :

1- I installed mail relay (postfix) on Server A.
2- I configure DCI on Server B ( i monitored the CPU,RAM,DiskSpace)
3- I follow the below link in order to create the policy, etc :
https://wiki.netxms.org/wiki/How_to_send_e-mail_notification_when_disk_space_is_low
4- I send a test e-mail from Server A using Postfix ( just to make sure that my postfix is able to connect to gmail)

Unfortunately , till now I could not make the Netxms to send alerts using Postfix ( i mean to send e-mail alerts). Is there any way to make this work I am really suffering 

attachments are :

Netxms_Server_Conf ( this SMTP config)
Netxms_Action( this action I made to send mails)


your support is highly appreciated as i am stuck in the project

Verify that you can send mail  using local postfix.

Connect using telnet or netcat:

telnet 127.0.0.1 25
nc 127.0.0.1 25


Sample session (my input in bold, change email address accordingly):

alk@mail:~$ nc 127.0.0.1 25

Yes it works when I tried your command and I received the e-mail  ,, but how to implement this in netxms itself 

You tried "mail" (or mailx, or sendmail) command - or SMTP?
If you are sure that SMTP is working - increase debug to 6 and look for entries with tag "SMTP"

I used the same command that you provided
-------------------

telnet 127.0.0.1 25

Hi,

this is not an error, just message dump with system event configuration being transmitted to client. If you have SMTP issues, you should look for lines with word SMTP.

Best regards,
Victor

Hi Victor,

I attached four images :

1- Specific DC configuration
2- Event that I create for physical Mem
3- event policy for that event
4- Action that will be triggered.
5- Finally Server SMTP Configuration.

kindly have a look at them and give me your feedback

Regards 

Hi,

configuration seems correct. Please filter server log by "SMTP:" messages and post them here. On debug level 8 server should log entire SMTP conversation.

Best regards,
Victor

Hi Vector,

finally it works , but i have one issue. the alarm is generated only one time. For example:

if the first polled value is exceeding the threshold ---> generate alarm then email

after that whatever next polled value it does not generate another alarm

can you please advise ?

Regards

any update please

Regards
