The munin-node service used wrapProgram to inject environment variables. This doesn't work because munin plugins depend on argv[0], which is overwritten when the executable is a script with a shebang line (example below). This commit removes the wrappers and instead passes the required environment variables to munin-node. Eliminating the wrappers resulted in some broken plugins, e.g., meminfo and hddtemp_smartctl. That was fixed with the per-plugin configuration. Example: The plugin if_eth0 is a symlink to /.../plugins/if_, which uses $0 to determine that it should monitor traffic on the eth0 interface. if_ is a wrapped program, and runs `exec -a "$0" .if_-wrapped` .if_-wrapped has a "#!/nix/.../bash" line, which results in bash changing $0, and as a result the plugin thinks my interface is called "-wrapped". |
