Email notification/alert for each new request on Virtual Server

Hmm, This seems not a real use case of F5 BIGIP. You can send new connection log to log server with help of HSL irule & it will utilize more cpu and risk of failover active device frequently.

However if your requirement is strict with mail trigger for every conenction then use TCL function in HSL iRule.

Happy iRulling...

Hi,
Have a look at this post: https://community.f5.com/t5/technical-forum/for-send-email-via-irule-procedures/td-p/128296 

You can use a procedure and a sideand connection to send an email on any trigger in an irule.

Cheers,

You are setting yourself up for a DoS attack on your email server. Also, that would be quite a bit of CPU on the F5. As mentioned above, the correct way would be to use High Speed Logging (HSL) to offload a custom message to a remote syslog, splunk, zabbix, whatever server. Then on that remove purpose built logging device I would setup rules for any email generation. Just because you can hack the F5 to do this, you shouldnt. Sometimes, it is best for the operational and security risk of your infrastructure to tell the business or application team that they are smoking too much grass, and that what they are requesting cant be done on the F5. Simple.
