- Revised X.500 "delivery" stats
- ------------------------------
-
- As John suggested at the last meeting, I revised the query program to
- also try "finger @umich.edu"'s matching rules. At the present time
- the "email @umich.edu" service does not use what I am calling "finger
- matching rules." For those of you who were at the meeting on Friday,
- adding the use of finger matching rules just breaks down the "not found"
- category into finer pieces. Also, I used different data to generate the
- new numbers I show below (I included yesterday's stats).
-
- Here are the summary numbers for email service queries for 6 days this
- past week (7/17-7/21 and 7/24):
-
- Unique Unique% Total Total%
- Count of queries: 411 3314
-
- De Deliverable: 315 76% 2921 88%
- Ae Ambiguous: 4 0% 6 0%
- Ee No email: 16 3% 25 0%
- Df Deliverable finger: 3 0% 6 0%
- Af Ambiguous finger: 50 12% 298 8%
- Ef No email finger: 6 1% 11 0%
- N Not found: 17 4% 47 1%
- O Other error: 0 0% 0 0%
-
-
- Here are the summary numbers for finger service queries for the same 6
- days this past week:
-
- Unique Unique% Total Total%
- Count of queries: 585 743
-
- De Deliverable: 169 28% 246 33%
- Ae Ambiguous: 14 2% 17 2%
- Ee No email: 108 18% 119 16%
- Df Deliverable finger: 15 2% 18 2%
- Af Ambiguous finger: 183 31% 218 29%
- Ef No email finger: 50 8% 73 9%
- N Not found: 44 7% 50 6%
- O Other error: 2 0% 2 0%
-
-
- Note that the "Unique" column only counts a particular query once
- while the "Total" column counts all occurrences. E.g., if "mcs"
- was queried 6 times during those 6 days, it would counts as 1 in
- the Unique column and 6 in the total column.
-
- A short explanation of the rows:
- De Deliverable Exactly one entry was matched using email
- matching rules and that entry has an email
- address in the "mail" field.
-
- Ae Ambiguous More than one entry was matched using email
- matching rules. The sender of the mail
- is returned a list of possiblities to choose
- from, along with the returned message.
-
- Ee No email Exactly one entry was matched using email
- matching rules, but that entry has no email
- address in its "mail" field.
-
- Df Deliverable finger Exactly one entry was matched using finger
- matching rules, and that entry has an email
- address in its "mail" field. Note that the
- current email service does not use finger
- matching rules, so at the present time this
- counts as "unknown user" error.
-
- Af Ambiguous finger More than one entry was matched using finger
- matching rules. See the note with "Df"
- above.
-
- Ef No email finger Exactly one entry was matched using finger
- matching rules, but that entry has no email
- address in its "mail" field. See the note
- with "Df" above.
- N Not found No entry matched using email or finger rules.
-
- O Other error The query generated some X.500 error that
- my test program didn't know what to do with.
- The only errors of this type were from one-
- character queries (the error was "permission
- denied" since we don't allow approximate
- searches to be done on a single character).
-
- A short explanation of the matching rules used by my stat generating
- program (they are tried in order until at least one match is found; if a
- match is found at any step, none of the subsequent steps are used):
-
- "EMail rules" are tried first:
- 1. look for an exact match for Uniqname (e.g. mcs@umich.edu)
- 2. look for an exact match for CommonName (e.g. Mark.Smith@umich.edu)
-
- "Finger rules" are tried if the above yielded no matches:
- 3. look for an exact match for Surname (e.g. smith@umich.edu)
- 4. look for an approximate (soundex-style) match for CommonName OR
- Surname (e.g. Mark.Smyth@umich.edu).
-
- These rules closely aproximate those used by the real umich.edu email
- and finger services.
