greyfix --dump-triplets format documentation

[Tom Hendrikx]

Hi,

I'm currently using greyfix for my personal mail server with great
succes. What i'm missing ios some report about its effectivity, and the
amounts of blocked messages. As I use munin for most reports, I have
written a number of plugins for it already, and am interested
in doing some work on greyfix too (unless someone else already has
written some greyfix plugin for munin).

I took a look at 'greyfix --dump-triplets' output, and think that this
would be appropriate for some kind of monitoring. I am not sure about
its format though. Could you explain the format used to me?

Regards,
Tom

This is interesting, do not hesitate to report your results: I'd like to
have something like that.

I'll have to add this to the documentation. In the mean time here it
is. Each line is of the form:

<client-address> <sender> <recipient> <create-time> <access-time> <block-count> <pass-count>

where (<client-address>, <sender>, <recipient>) form the greylisting
triplet:

- <client-address> is the IP address of the SMTP client,
- <sender> is the envelope sender (MAIL FROM line in SMTP),
- <recipient> is the envelope recipient (RCPT TO line in SMTP),
- <create-time> is the time the triplet was first seen,
- <access-time> is the time the triplet was last seen,
- <bloc-count> is the number of times the triplet was greylisted,
- <pass-count> is the number of times the triplet was accepted.

I thought I might just follow up on this old message: I tried to write
various plugins but in the end only one of them seemed really
informative: the amount of triplets in the database, and their age.

I ran the plugin for a while, concluding that the other variants I tried
were not very useful. Until this week I was too lazy to cleanup the
code, but now I did cleanup, and fine-tuned the part that was working.

Attached is the plugin code. I'll also submit it to the munin-exchange
website.
