This is munin-node-sh

It's a munin-node alternative written entirely in shell, with minimal dependencies. It doesn't work yet. Or at least, it may not. YMMV.

Munin-node-sh is not associated with or part of the Munin project.

Munin-node-sh provides a number of plugins internally:

• df
• zfslist
• cpu
• if_
• if_err_
• load
• memory
• swap
• processes
• netstat
• uptime

Other plugins may be provided via the standard plugin directory ... the location of which is configurable.

Requirements:

Munin-node-sh has pretty light-weight requirements. No build should be required. Available plugins are determined by configuration and the set of dependencies that are found. For example:

Dependency	Services
smartctl	disk temperature
zfs	zfslist, for dataset usage (like df but better)
zpool	IO statistics for a given ZFS pool

Provisos:

• At the moment, munin-node-sh handles only one node, the local machine (per hostname), and ignores any specification of node by the server. This may be adjusted in future versions, but probably not, in the interest of keeping munin-node-sh as light-weight as possible.

• MuninLite is a Bourne shell replacement for munin-node and some plugins. Looks like its goals are the same as munin-node-sh's goals. Hasn't been updated since 2011.
