MINOR: ssl: Add 'show ssl ocsp-updates' CLI command
This command can be used to dump information about the entries contained in the ocsp update tree. It will display one line per concerned OCSP response and will contain the expected next update time as well as the time of the last successful update, and the number of successful and failed attempts.

|

|
||||
show ssl ocsp-updates
|
||||
Display information about the entries concerned by the OCSP update mechanism.
|
||||
The command will output one line per OCSP response and will contain the
|
||||
expected update time of the response as well as the time of the last
|
||||
successful update and counters of successful and failed updates. It will also
|
||||
give the status of the last update (successful or not) in numerical form as
|
||||
well as text form. See below for a full list of possible errors. The lines
|
||||
will be sorted by ascending 'Next Update' time. The lines will also contain a
|
||||
path to the first frontend certificate that uses the OCSP response.
|
||||
See "show ssl ocsp-response" command and "ocsp-update" option for more
|
||||
information on the OCSP auto update.
|
||||
|
||||
The update error codes and error strings can be the following:
|
||||
|
||||
+----+-------------------------------------+
|
||||
| ID | message |
|
||||
+----+-------------------------------------+
|
||||
| 0 | "Unknown" |
|
||||
| 1 | "Update successful" |
|
||||
| 2 | "HTTP error" |
|
||||
| 3 | "Missing \"ocsp-response\" header" |
|
||||
| 4 | "OCSP response check failure" |
|
||||
| 5 | "Error during insertion" |
|
||||
+----+-------------------------------------+
|
||||
|
||||
