for Send Email via iRule Procedures .

Hello,

I think there is a bit of interpretation missing from this iRule content, and you should be going through a method overload problem.

See this line:

call thisiRule::sendEmail $errorSubject $errorBody

"thisiRule" means the iRule name what you are creating.

and in this other line:

catch {call procLibrary::sendEmail $subject $body "email1@myorg.org email2@myorg.org"}

Indicates that the overload method sendEmail, has to be in another irule e.g. "procLibrary"

So, try creating the methods in different libraries (iRules), e.g.:

"thisiRule" content:

 this Irule sends an email to the F5 admin via the mailserver.myorg.org mailserver. This iRule calls the procedure in the procLibrary iRule.

when HTTP_RESPONSE {
    set error 0
    if {$error} {
        set errorSubject "F5 Email Notification."
        set errorBody "There was an event that happened. Check your F5 local log!"
        call thisiRule::sendEmail $errorSubject $errorBody
    }
    else {
        Do something cool
    }
}   
proc sendEmail {sourceSubject sourceBody} {
        set currentTime [clock format [clock seconds] -format {%H:%M:%S}]
        set todaysDate [clock format [clock seconds] -format {%m-%d:%Y}]
        set subject ${sourceSubject}
        set body "${sourceBody}\r\n\r\n ${currentTime}hrs on ${todaysDate}.\r\n\r\n This is an automated email sent via the this iRule iRule.\r\n\r\nSincerely,\r\nYour F5 Support Team"
        log local0. $body
        catch {call procLibrary::sendEmail $subject $body "email1@myorg.org email2@myorg.org"}
}

"procLibrary" irule content:

 This procedure library procLibrary sends an email using a sideband connection to your organizations email server.
 It has 3 input parameters; subject, body and additional email addresses. The calling procedure needs to seperate the additional 
   emails with a " ". Example "email1@myorg.org email2@myorg.org".

proc sendEmail {sourceSubject sourceEmailBody sourceAddEmailAddress} {
    upvar 1 $sourceSubject n1
    upvar 1 $sourceEmailBody n2
    upvar 1 $sourceAddEmailAddress n3
    set email_debug 0
    set hostName [info hostname]
    set mailFrom "root@$hostname"
    set mailTo "admin@myorg.org"
    set mailServer "xxx.xxx.xxx.xxx:25"
    set subject $sourceSubject
    set emailBody $sourceEmailBody
    set addEmailAddress ""
    if {$sourceAddEmailAddress ne ""} {
        append sourceAddEmailAddress "${mailTo}"
        foreach emailAddress $sourceAddEmailAddress {
            set emailConn [connect -timeout 2000 -idle 10 -status conn_status $mailServer]
            if {$email_debug} {log local0. "connect_status: $conn_status"}
            set emailData "HELO mailserver.myorg.org\r\nMAIL FROM: $mailFrom\r\nRCPT To: ${emailAddress}\r\nDATA\r\nSUBJECT: \r\n\r\n\r\n$emailBody\r\n.\r\n"
            set send_info [send -timeout 2000 -status send_status $emailConn $emailData]
            if {$email_debug} {log local0. "emailData: $emailData"}
            if {$email_debug} {log local0. "send_status: $send_status"}
            set recv_data [recv -timeout 2000 -status recv_status $emailConn]
            if {$email_debug} {log local0. "recv_Data: $recv_data"}
            close $emailConn
            if {$email_debug} {log local0. "EmailTo: $emailAddress"}
        }
    }
    else {
        if {$email_debug} {log local0. "connect_status: $conn_status"}
        set emailData "HELO mailserver.myorg.org\r\nMAIL FROM: $mailFrom\r\nRCPT To: ${emailAddress}\r\nDATA\r\nSUBJECT: \r\n\r\n\r\n$emailBody\r\n.\r\n"
        set send_info [send -timeout 2000 -status send_status $emailConn $emailData]
        if {$email_debug} {log local0. "emailData: $emailData"}
        if {$email_debug} {log local0. "send_status: $send_status"}
        set recv_data [recv -timeout 2000 -status recv_status $emailConn]
        if {$email_debug} {log local0. "recv_Data: $recv_data"}
        close $emailConn
    }   
}

Particulary, I prefer to rewrite all this content to one iRule, if use it to simple thing.

I hope it helps you.
