To handle the json output format of the pgBackRest info command, you need to install the following module:
- on RedHat-like:
perl-JSON - on Debian-like:
libjson-perl
The Data::Dump perl module is also needed:
- On RedHat-like:
perl-Data-Dumper - On Debian-like:
libdata-dump-perl
To install check_pgbackrest using the PGDG repositories:
yum install -y epel-release
yum install -y nagios-plugins-pgbackrest
The rpm will also require nagios-plugins to be installed and put the
check_pgbackrest script there.
That's why the epel-release package is needed too.
To install check_pgbackrest using the PGDG repositories (located in /usr/bin):
apt-get -y install check-pgbackrest
