Package: munin-plugins-extra Version: 2.0.42-5~bpo9+1 Severity: normal Dear Maintainer,
There was an issue¹ reported to munin github which proposed a "fix" for
one person's hardware, that broke on everyone elses hardware.
Looking at two servers (both SuperMicro), showing ipmitool output and
munin-run output with the version of ipmi_sensor_ in the 2.0.33-1
package:
server1# ipmitool -I open sensor get "FAN 1"
Locating sensor record...
Sensor ID : FAN 1 (0x41)
Entity ID : 29.1
Sensor Type (Threshold) : Fan
Sensor Reading : 4800 (+/- 0) RPM
Status : ok
Lower Non-Recoverable : 300.000
Lower Critical : 450.000
Lower Non-Critical : 600.000
Upper Non-Critical : 18975.000
Upper Critical : 19050.000
Upper Non-Recoverable : 19125.000
Positive Hysteresis : 75.000
Negative Hysteresis : 75.000
Assertion Events :
Assertions Enabled : lcr- lnr- unc+ ucr+ unr+
Deassertions Enabled : lcr- lnr- unc+ ucr+ unr+
server1# munin-run ipmi_sensor_u_rpm config | grep fan_1
fan_1.label FAN 1
fan_1.warning :18975.000
fan_1.critical 450.000:19050.000
server2# ipmitool -I open sensor get "FAN1"
Locating sensor record...
Sensor ID : FAN1 (0x41)
Entity ID : 29.1
Sensor Type (Threshold) : Fan
Sensor Reading : 800 (+/- 0) RPM
Status : ok
Lower Non-Recoverable : 300.000
Lower Critical : 500.000
Lower Non-Critical : 700.000
Upper Non-Critical : 25300.000
Upper Critical : 25400.000
Upper Non-Recoverable : 25500.000
Positive Hysteresis : 100.000
Negative Hysteresis : 100.000
Assertion Events :
Assertions Enabled : lcr- lnr- ucr+ unr+
Deassertions Enabled : lcr- lnr- ucr+ unr+
server2# munin-run ipmi_sensor_u_rpm config | grep fan1
fan1.label FAN1
fan1.critical 500.000:25400.000
Compared to munin-run output with the version of ipmi_sensor_ in the
2.0.42-5~bpo9+1 package:
server1# munin-run ipmi_sensor_u_rpm config | grep fan_1
fan_1.label FAN 1
fan_1.warning 18975.000:
^^^^^^^^^^
fan_1.critical 19050.000:450.000
^^^^^^^^^^^^^^^^^
server2# munin-run ipmi_sensor_u_rpm config | grep fan1
fan1.label FAN1
fan1.critical 25400.000:500.000
^^^^^^^^^^^^^^^^^
The Lower/Upper, Critical/Non-Critical values have been reversed.
The following lines of code in the plugin are causing this reversal:
268: # TODO add 'fans'
269: if 'rpm' == unit:
270: warn = "%s:%s" % (warn_u, warn_l)
271: crit = "%s:%s" % (crit_u, crit_l)
272: else:
273: warn = "%s:%s" % (warn_l, warn_u)
274: crit = "%s:%s" % (crit_l, crit_u)
Apologies for not commenting on the upstream github repository directly,
as I do not have a github account. However another user had reported
the same problem in the last comment² of the closed bug report.
