sh: psql: 在 Zabbix 模板中找不到命令

Question

There is a template for monitoring PostgreSQL

Zabbix v3.2

Zabbix_agent is installed on another server and monitors PostgreSQL 9.6 there. The host is active in the Zabbix server in the web interface, there are no errors. Partially zero values from the database are output to the template on the Zabbix server and there are

sh: psql: command not found

enter image description here

Answer 1

You are attempting to execute /usr/pgsql-9.6/bin/psql .

If that postgres directory is not in the $PATH env var, then trying just psql won't work and will produce a "command not found" diagnostic.

Either tell Zabbix to execute the full pathname, or put the postgres directory in Zabbix's PATH, or choose a directory already in Zabbix's PATH and add a symlink to it. For example:

$ cd /usr/bin
$ sudo ln -s /usr/pgsql-9.6/bin/psql
