#5 Avoid "setting unknown option …" on ethernet interfaces

2020-02-12T03:16:45.989000Z

The issue is now fixed (in muninlite's new home at github):
https://github.com/munin-monitoring/muninlite/commit/44d1c8dc3aef0186bf6934fd1307133703f7916f

Thank you!

#6 Avoid remote file systems usage reporting

2020-02-12T03:15:19.309000Z

Now muninlite (in its new home at github) excludes at least virtual and read-only filesystems:
https://github.com/munin-monitoring/muninlite/commit/44628e78cc50094fcbf3765e68ee5b932139e833Remote

Remote filesystems are still being monitored, since it does not really cause harm (and one of muninlite's priorities is simplicity).

Your suggestion regarding the mistreated backreference also found its way into muninlite. Thanks!

#8 uptime reports seconds instead of days

munin-lite on Drobo 5N

2017-12-30T17:54:13.249000Z

I was able to get munin-lite working on my Drobo 5N.
Thetricky bit was to report the actual free space rather than the logical capacity.

To install:

Place munin-node.sh in /usr/local/bin.

Add this line to /etc/inetd.conf:

munin   stream  tcp     nowait  root    /usr/local/bin/munin-node.sh

If you don't have the inetd app installed, add service.sh to /mnt/DroboFS/Shares/DroboApps/inetd

You can see the plugin working here: http://eee.hsmiths.com:49002/munin/Drobo5N/Drobo5N/

Thanks!

uptime reports seconds instead of days

2015-01-22T05:19:53.817000Z

The uptime plugin as documented in this code as well as the main munin repository reports time in days. The plugin in this implementation simply returns the data in /proc/uptime, which is reported in seconds. This causes a problem when mixing uptime data from this version of munin-node and the full version.

Attached is a patch that changes this plugin to report days instead. It's similar to the awk command used in the full version except it uses a print statement instead of a newline character (the Makefile does not handle stitching together plugins that contain newline characters properly).

muninlite on DD-WRT

2012-12-17T05:50:10Z

Muninlite worked great on OpenWRT but I encountered some difficulties on DD-WRT, as some plugins behaved differently:
* The if_ plugins would always exit with:
munin_set_var_loc: Setting unknown option '_tmp_munin_node_' at example.org;router.example.org:if_etherip0
* The df_ plugin would return an empty set because "df -P /" did not work - but "df -P" did.
* While I was on it, I did some whitespace cleanup, hence the bigger size of the patch:

Avoid remote file systems usage reporting

2012-11-27T12:44:01Z

I'm running muninlite on my Dreambox. I had 2 problems with df plugin:
- the output of df is split to 2 lines for filesystems with long names (e.g. samba shares), example:
//192.168.100.200/videos
940093832 696245876 243847956 74% /media/net/videos
- my 'sed' has problems with the ^A character in the expression

What I ended up with is to remove filesystems that begin with // (I don't need to monitor remote filesystems usage, because they are monitored on the remote machine).
I replaced the ^A character with \1.
Here are my 2 changes:
1. for PART in $(df -P | grep -v '^//' | grep '^/' | sed '/\/[a-z0-9]*$/!d;s/.* $[a-z0-9\/]\{1,\}$$/\1/g')
2.

Avoid "setting unknown option …" on ethernet interfaces

2011-04-06T12:35:07Z

Hi,

I recently saw that my OpenWRT router (using munin-lite) was causing some errors in my munin logs. The problem is that when running ethtool on some ethernet interfaces from which one cannot get the speed, it spits out some error message on stderr that get transmitted as plotting data…
The following patch fixes that, by redirecting stderr to /dev/null when calling ethtool. (I did not do it for the second call too, because I think that if it passes the first call, the second one is ok)
BTW, maybe another solution would be not to pass /dev/stderr as plotting data altogether, but I'll let you decide.

Regards,
Benjamin

With the patch on previous version of munin (1.0.2), it works, i think it should work with munin 1.0.3

make use of plugins provided in a dir (runtime plugins)

2010-07-25T20:16:14Z

Muninlite aleady has a plugin architecture, which is considered at build-time. In some cases it is more convenient to provide plugins in forms of executables and/or scripts.

This patch adds this feature and works as follows.
PLUGINPATTERN variable gives a shell pattern, and executable regilar files matching this pattern are regarded as plugins.
The runtime config present in muninlite discovers plugins and adds them in the RES plugin list. In case of name collision, plugindir_ name prefix is added.

The attached patch is a diff made between the modified and original 1.0.0 muninlite script "munin-node". It should be adjusted to fit the muninlite build process.
