redis-cli: command not found

[kvz]

Hi,

I'm getting the error

$ tail /var/log/munin/munin-node.log

2017/02/02-10:24:30 [21429] Error output from redis_127.0.0.1_6379:
2017/02/02-10:24:30 [21429] 	/etc/munin/plugins/redis_127.0.0.1_6379: line 61: redis-cli: command not found

Which is weird because it's installed here:

$ type redis-cli
redis-cli is /srv/recent/12659/stack/bin/redis-cli

And my redis plugin is configured to use this path also. It's a bit noisy, but you can see /srv/recent/12659/stack/bin is listed:

$ sudo cat /etc/munin/plugin-conf.d/redis

[redis_*]
env.PATH /srv/recent/12659/api2/bin:/srv/recent/12659/core/bin:/srv/recent/12659/stack/lib/ruby/gems/2.1.0/gems/bin:/srv/recent/12659/stack/lib/ruby/gems/2.1.0/gems/ruby/2.1.0/bin:/srv/recent/12659/stack/bin:/srv/recent/12659/stack/sbin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin

At first I thought that the plugin somehow did not respect the env.PATH.

But echoing $PATH from /etc/munin/plugins/redis_127.0.0.1_6379 outputs the correct path. The PWD is / at that point, if it helps.

Somewhat desperate I symlinked my redis-cli to a more conventional place:

ln -nfs "${DM_STACK_DIR}/bin/redis-cli" /usr/bin/redis-cli

But the error remains. Any clues? All my other plugins work without issues.
