[hardware::ups::apc::snmp::plugin] input-lines mode - automatic warn/crit thresholds for upsAdvInputLineVoltage no more work

[Aleksey-Maksimov]

Hello,

In December 2019, our mutual friend Quentin (@garnier-quentin) kindly added the ability to automatically calculate the upper and lower thresholds for the incoming voltage of the APC UPS
#1764
Previously, this worked fine and we did not specify the thresholds - the plugin took them automatically from the NMC.

But recently we noticed that this does not work anymore, that is, the values ​​upsAdvConfigHightransferVolt (.1.3.6.1.4.1.318.1.1.1.5.2.2.0) and upsAdvConfigLowTransferVolt (.1.3.6.1.4.1.318.1.1.1.5.2.3.0) are no longer processed correctly. The data from these OIDs does not get into the perfdata and does not affect the return code of the plugin in any way.

This looks like a significant regression and breakage of useful functionality of the plugin that worked before.

For example, we have disconnected the input voltage and we found that the "input-lines" mode incorrectly shows us the status of the input voltage (OK instead of CRITICAL)

# '/centreon_plugins.pl' '--plugin=hardware::ups::apc::snmp::plugin' '--mode=input-lines' \ 
'--critical-frequence' '49:51' '--filter-uom' 'null' '--hostname' 'UH-UP004' \
'--snmp-community' 'it' '--snmp-version' '2c' '--use-new-perfdata' --verbose --debug

OK: voltage: 0 V, frequence: 50 Hz, last input line fail cause is 'rateOfVoltageChange' | 
'lines.input.voltage.volt'=0;;;; 'lines.input.frequence.hertz'=50;;49:51;;

.1.3.6.1.4.1.318.1.1.1.3.2.1.0 = 0
.1.3.6.1.4.1.318.1.1.1.3.2.4.0 = 50
.1.3.6.1.4.1.318.1.1.1.3.2.5.0 = 10
.1.3.6.1.4.1.318.1.1.1.3.3.1.0 = 0
.1.3.6.1.4.1.318.1.1.1.3.3.4.0 = 500
.1.3.6.1.4.1.318.1.1.1.5.2.2.0 = 253
.1.3.6.1.4.1.318.1.1.1.5.2.3.0 = 208

Please fix this problem.

Hello :)

This looks like a threshold issue as explained in this doc section : Ranges of values.
If you add '--critical-frequence' '@49:51' the service switches to CRITICAL status when the metric is within a range of values (between 49 and 51 in your case).

Hello

Sorry I couldn't respond promptly.
You closed this issue, but the problem wasn't solved.
I was talking about automatically determined thresholds for the lines.input.voltage.volt metric. As I said, it worked before, but now it doesn't. You mentioned frequency, but your question was about something completely different. It was about voltage.

Hello :)

Ok sorry for my bad understanding, I will be away for a while, so I will not be able to follow up on this topic for the moment.
