昨日になって急に気付いたのだが、日時でログを集計しているのqmailanalogが正常に動いていないみたい。

こんな感じで一件集計されているように見えるけど、
deferralのメッセージがあるのにzdeferralsのデータがなかったり、
zrhosts・zfailures・zsuids・zdeferralsが動いていない模様。

Basic statistics

qtime is the time spent by a message in the queue.

ddelay is the latency for a successful delivery to one recipient---the
end of successful delivery, minus the time when the message was queued.

xdelay is the latency for a delivery attempt---the time when the attempt
finished, minus the time when it started. The average concurrency is the
total xdelay for all deliveries divided by the time span; this is a good
measure of how busy the mailer is.

Completed messages: 153
Recipients for completed messages: 153
Total delivery attempts for completed messages: 153
Average delivery attempts per completed message: 1
Bytes in completed messages: 1501110
Bytes weighted by success: 1501110
Average message qtime (s): 1.12839

Total delivery attempts: 153
success: 153
failure: 0
deferral: 0
Total ddelay (s): 165.507989
Average ddelay per success (s): 1.081752
Total xdelay (s): 122.277667
Average xdelay per delivery attempt (s): 0.799200
Time span (days): 0.945623
Average concurrency: 0.00149663

-----------Result of zddist------------
Distribution of ddelays for successful deliveries

Meaning of each line: The first pct% of successful deliveries
all happened within doneby seconds. The average ddelay was avg.

doneby avg pct
0.27 0.17 10
...
4.24 1.08 100

-----------Result of zdeferrals------------
Reasons for deferral

One line per reason for deferral. Information on each line:
* del is the number of deliveries that ended for this reason.
* xdelay is the total xdelay on those deliveries.

del xdelay reason

-----------Result of zfailures------------
Reasons for failure

One line per reason for delivery failure. Information on each line:
* del is the number of deliveries that ended for this reason.
* xdelay is the total xdelay on those deliveries.

del xdelay reason

-----------Result of zrhosts------------
Recipient hosts

One line per recipient host. Information on each line:
* sbytes is the number of bytes successfully delivered to this host.
* mess is the number of messages sent to this host (success plus failure).
* tries is the number of delivery attempts (success, failure, deferral).
* xdelay is the total xdelay incurred by this host.

sbytes mess tries xdelay host

-----------Result of zsuids------------
Sender uids

One line per sender uid. Information on each line:
* mess is the number of messages sent by this uid.
* bytes is the number of bytes sent by this uid.
* sbytes is the number of bytes successfully received from this uid.
* rbytes is the number of bytes from this uid, weighted by recipient.
* recips is the number of recipients (success plus failure).
* tries is the number of delivery attempts (success, failure, deferral).
* xdelay is the total xdelay incurred by this uid.

mess bytes sbytes rbytes recips tries xdelay uid

-----------Result of zrxdelay------------
Recipients in the best order for mailing lists

One line per recipient, sorted by avg. Information on each line:
* avg is the _average_ xdelay for the recipient.
* tries is the number of deliveries that avg is based on.

そこで再インストールしたり、qmailanalogのスクリプトを直したりしたんだけど効果なし。

んでいろいろ調べてみたら、やっとのことで発見しました。

ひとにやさしく : sort の -k オプション

どうやらsortのオプションが変わったことが原因で集計が出来ていなかったみたい。
公開しているパッチ適用してから再インストールすると、きちんと集計されるようになりました。
