check_pgbackrest 1.9 has been released

Mons, Belgium, July 28, 2020

check_pgbackrest is designed to monitor pgBackRest backups from Nagios, relying on the status information given by the info command.

It allows to monitor the backups retention and the consistency of the archived WAL segments.

Changes in check_pgbackrest 1.9

• The archives service will now only look at the archives listed between the oldest backup start archive and the max WAL returned by the pgBackRest info command. This should avoid unnecessary alerts. To extend the check to all the archives found, the new --extended-check argument has been implemented (suggested by blogh).
• Remove refresh of pgBackRest info return after getting the archives list. That avoids CRITICAL alert if an archive is generated between those two steps. Instead, a WARNING message "max WAL is not the latest archive" will be displayed (suggested by blogh).
• Fix S3 archives detection (reported by khadijahvf).
• New enable-internal-pgbr-cmds argument, for pgBackRest >= 2.28. Internal pgBackRest commands will then be used to list and get the content of files in the repository instead of Perl specific drivers. This is, for instance, needed to access encrypted repositories. This should become the default and only access method in the next release, removing some Perl dependencies.
