Bug 549026 – net-analyzer/munin: smart plugin: Unable to parse the link and smartoutput

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description georg 2015-05-09 16:17:11 UTC]

I want munin to monitor the smart values of my server drives. 

ls -la /etc/munin/plugins/smart_sda 
lrwxrwxrwx 1 root root 33  9. Mai 00:48 /etc/munin/plugins/smart_sda -> /usr/libexec/munin/plugins/smart_

Smart finds my sda drive
smartctl -H /dev/sda
smartctl 6.3 2014-07-26 r3976 [x86_64-linux-3.15.10-hardened-r1-server] (local build)
Copyright (C) 2002-14, Bruce Allen, Christian Franke, www.smartmontools.org

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED

The script /usr/libexec/munin/plugins/smart_ fails to parse the linkname in line 236. They always access name[0]. after the line
name=[plugin_name[string.index(plugin_name,'_')+1:]]

name is empty. name[0] is empty too.

In the function get_hard_drive_name() i replaced all  name[0] with name and it succedded. I manually set name to sda. I am not so familar with python to debug the whole script ... 

I tried to switch to python 2.7 and 3.3. 2,.7 did work better than 3.3 but not perfect (no values).



Reproducible: Always

Steps to Reproduce:
1. emerge munin
2. set verbose level to True (line 91)
3. ln -s /usr/libexec/munin/plugins/smart_ /etc/munin/plugins/smart_sda
4. cd /etc/munin/plugins/
5. ./smart_sda
Actual Results:  
Can not find smart values.

Expected Results:  
output of smart values.

In the function def read_values(hard_drive) when i output the device to the log it is just "/dev/s" and not /dev/sda. Manually setting it to /dev/sda brings it a litte further but not to the end ....
