A LONG time ago I asked about ack'ing an alert via email (or via sms-to-email) and to be able to do so without a subject. A patch was written at the time and it was included into the main codebase but unfortunately I did not get a chance to imeplement what I wanted to and never ended up testing it. Thats has just changed recently and now I am having issues acking an alert via text in the body.

If i reply to an email and maintain the subject it works fine, if I try cut the subject and paste it as the body nothing happens. I havent gone as far as testing it via the sms-to-email app yet as I cant get it working from a normal email.

The hobbit-mailack.c program loops through the incoming email, looking for interesting stuff. Here's where it finds the subject line:

 else if (strncasecmp(STRBUF(inbuf), "subject:", 8) == 0)
     subjectline = strdup(skipwhitespace(STRBUF(inbuf)+8));

Once the headers are done with, it goes on to look for some things in the email body, such as "delay=" and "ack=":

 else if ((strncasecmp(STRBUF(inbuf), "ack=", 4) == 0) ||
            (strncasecmp(STRBUF(inbuf), "ack ", 4) == 0)) {
                            /* Some systems cannot generate a subject.

Allow them to ack * via text in the message body. */ subjectline = (char *)malloc(1024); snprintf(subjectline, 1023, "Subject: Hobbit [%s]", STRBUF(inbuf)+4); }

So, does the email body contain a line that starts with "ack=NNNNNN" or "ack NNNNN"?? If not, it won't match the above code fragment. It looks like it should be *just* the number, as that gets filled in between the square brackets in the faked subject line.

I noticed something else interesting in the code. The last thing it does is call sendmessage, handing it a buffer loaded like this:

 p += sprintf(p, "hobbitdack %s %d %s", cookie, duration, firsttxtline);
    if (fromline) {
       p += sprintf(p, "\nAcked by: %s", fromline);
    }

I figured it wouldn't hurt to try doing this:

 server/bin/bb localhost "hobbitdack NNNNNN 60 this thing is broken
 Acked by: me at this.domain.com"

where NNNNNN came from a real, current warning message. Note the placement of the double-quotes - there needs to be a newline between the message and "Acked by". And now, just below the "Status unchanged in...." message at the bottom of the page I find this:

      Current acknowledgment: this thing is broken
           Acked by: me at this.domain.com
           Next update at: 12:54 2008-07-09

and there's a nice yellow check mark on the all-non-green page. So it looks like an ACK *can* be sent via the command line...

New subject: Recipients on a Per-Filesystem basis?

Hi All,

Can E-mail recipients for alerts be configured on a per-filesystem basis (not just SERVICE=DISK)?

Thanks!

New subject: [hobbit] Recipients on a Per-Filesystem basis?

Yes. Simply define a group in hobbitclients and use the group name in hobbit alerts.

Example follows.

hobbit clients: ... HOST=servera,serverc,serverfoo DISK %^/foo.* 95 98 GROUP=FOO_ADMINS DISK %^/moo.* 95 98 GROUP=MOO_ADMINS ...

hobbit alerts ... HOST=servera,serverc,serverfoo GROUP=FOO_ADMINS COLOR=red ...

Cheers Ralph you identified my missing link. I was under the impression that the body needed to be in the same format as the subject but as you have identified thats not the case. I have just test a plain email with ack=xxxx in the body and it worked a charm so hopefully a little later on I can try it end to end via SMS.

I knew Henrik coded it in there when I asked a while ago but unfortunately I never got the chance or the capability to test it back then.

Thanks Allan

Possibly for a good reason - I expect to get slapped by Henrik... :)
