mailping setup

[Johann Spies <jspies@sun.ac.za>]

I am trying to get mailping to work.  When finished, I want it to be
able to produce graphs in Munin for our three mail servers.  At the
moment, I am trying out the new-to-be-put-in-production-soon server:
mail2a

I am monitoring it from a server (archive.sun.ac.za) which is not part
of the mail gateway.

I have the following in /etc/mailping:

/etc/mailping/mail2a
/etc/mailping/mail2a/admin
/etc/mailping/mail2a/failtime
/etc/mailping/mail2a/interval
/etc/mailping/mail2a/to
/etc/mailping/mail2a/from
 
and 'to' contains mailping@mail2a.sun.ac.za with
'from': mailping@archive.sun.ac.za

In /etc/aliases on mail2a I have:

mailping: mailping@archive.sun.ac.za

The following exists in /var/lib/mailping

|-- Maildir [error opening dir]
`-- state
    `-- mail2a
        |-- failtime
        |-- incoming
        |-- pending
        |-- success
        `-- warntime

5 directories, 3 files
14:15:00 js@ftp:/var/lib/mailping$ sudo tree .
.
|-- Maildir
|   |-- cur
|   |-- new
|   `-- tmp
`-- state
    `-- mail2a
        |-- failtime
        |-- incoming
        |-- pending
        |-- success
        `-- warntime

8 directories, 3 files

When /var/lib/mailping/state/mail2a/success is a normal file, the
error message is: 

$ sudo munin-run mailping-success fetch
Traceback (most recent call last):
  File "/etc/munin/plugins/mailping-success", line 69, in ?
    dump()
  File "/etc/munin/plugins/mailping-success", line 61, in dump
    success = fileutil.getTime(os.path.join(statedir, 'state', dirname, 'success'))
  File "/usr/lib/python2.3/site-packages/MailPing/fileutil.py", line 16, in getTime
    return float(l)
ValueError: empty string for float()


When it is a directory the error message is:

Traceback (most recent call last):
  File "/etc/munin/plugins/mailping-success", line 69, in ?
    dump()
  File "/etc/munin/plugins/mailping-success", line 61, in dump
    success = fileutil.getTime(os.path.join(statedir, 'state', dirname, 'success'))
  File "/usr/lib/python2.3/site-packages/MailPing/fileutil.py", line 8, in getTime
    f=open(path)
IOError: [Errno 21] Is a directory


The documentation is not very clear to me.  I will appreciate some
help.

Regards
Johann

      us according to our iniquities. For as the heaven is 
      high above the earth, so great is his mercy toward 
      them that fear him. As far as the east is from the 
      west, so far hath he removed our transgressions from 
      us."                  Psalms 103:10-12
