    Template Net Arista SNMP Voltage/Fan/Temperature Trigger Thresholds

    Wondering if anyone has experience with Template Net Arista SNMP Fan/Temperature/Voltage Trigger Thresholds, specifically, my problem is that the trigger prototypes are creating triggers with thresholds that appear to be incorrect as per below?
    OK Temperature discovery: CPU board temp sensor: Temperature is below the critical threshold of -1000000000°C for 5m Current value: {ITEM.LASTVALUE1} {switch1:sensor.temp.value[entPhySensorValue.100006015].max(5m)} < -1000000000 Disabled
    Warning OK Temperature discovery: CPU board temp sensor: Temperature is below the warning threshold of -1000000000°C for 5m
    Depends on:
    switch1: CPU board temp sensor: Temperature is below the critical threshold of -1000000000°C for 5m    		 Current value: {ITEM.LASTVALUE1} {dmol01-lf1a:sensor.temp.value[entPhySensorValue.100006015].max(5m)} < -1000000000 Disable
    Warning OK Voltage discovery: CpucardPwrCon Rail1 12V: Voltage is below the warning threshold of -1000000000V for 5m
    Depends on:

    High OK Voltage discovery: CpucardPwrCon Rail2 5V ALW: Voltage is above the critical threshold of 1000000000V for 5m Current value: {ITEM.LASTVALUE1} {dmol01-lf1a:sensor.voltage.value[entPhySensorValue.100006102].min(5m)} > 1000000000

      What is your Zabbix version?
      Are you using an out-of-box template?

      Your Arista template might use overrides for its thresholds. Maybe you could check that in your temperature/power discovery.

          Hello, Zabbix version is Zabbix 5.0.14 and Template Net Arista SNMP is an out of the box template. In the voltage discovery:

          Under "Filters" there is a macro called {#SENSOR_TYPE} set to "matches" regular expression 3|4.

          Under the "Overrides" tab:
          Overrides
          1: trigger THRESHOLD_LO_WARN No
          2: trigger THRESHOLD_LO_CRIT No
          3: trigger THRESHOLD_HI_WARN No
          4: trigger THRESHOLD_HI_CRIT No
          Add

              Fan Discovery:

              Macro {#SENSOR_TYPE} set to "matches" regular expression "10"

              Overrides
              1: trigger THRESHOLD_LO_WARN No Remove
              2: trigger THRESHOLD_LO_CRIT No Remove
              3: trigger THRESHOLD_HI_WARN No Remove
              4: trigger THRESHOLD_HI_CRIT No Remove
              Add
              What I don't want to do is have to hard code triggers etc at the host level. I want everything done at the template level so that it is uniform across all Arista switches (approximately 30 devices)

              Thank you for your time.

                  I'm not familiar with Arista devices, but I'm trying to understand the logic behind Arista discovery.

                  With Arista template, Voltage and temperature comes from "Get Sensors" item.

                  So, "Get sensors" item returns a list of discovered entities and their raw values, all in JSON format. Acccording to doc, "the returned value contains a list of macro → value pairs":
                  In Arista template they are:
                  {#SENSOR_TYPE}, (...), {#THRESHOLD_LO_WARN}, {#THRESHOLD_LO_CRIT}, {#THRESHOLD_HI_WARN} and {#THRESHOLD_HI_CRIT}

                  If you use "snmpget", what values do you get by querying the above items (OIDs are in template's item)?

                  After you link your template to your host, what kind of raw values are you getting from these items "sensor.temp.value[entPhySensorValue.100006015]" and "{sensor.voltage.value[entPhySensorValue.100006101]"?
                  What does the Arista switch documentation says about temperature and voltage values?

                      Here is an example of voltage from the host's latest data.

                      CpucardPwrCon Rail1 12V: Voltage 2021-08-10 17:10:02 1.19 KV -1 V
                      CpucardPwrCon Rail2 5V ALW: Voltage 2021-08-10 17:10:02 507 V
                      CpucardPwrCon Rail3 3.3V ALW: Voltage 2021-08-10 17:10:02 329 V
                      CpucardPwrCon Rail4 1.8V ALW: Voltage 2021-08-10 17:10:02 179 V
                      Example for temperature:
                      Temperature (60 Items)
                      Back-panel temp sensor: Temperature 2021-08-10 17:12:02 28.6 °C
                      Back-panel temp sensor: Temperature status 2021-08-10 17:12:02 ok (1)
                      CPU board temp sensor: Temperature 2021-08-10 17:12:02 31.5 °C +0.1 °C
                      CPU board temp sensor: Temperature status 2021-08-10 17:12:02 ok (1)

                      So it appears that there is no issue with the actual data, the issue lies in the trigger prototypes and the triggers themselves.

                          It seems the trigger thresholds are defined by switch itself.
                          Arista template only collects that threshold and use it for the triggers.

                          The OID bellow suggests that no threshold was configured in your device. Maybe that is why previews OIDs show strange values.
                          iso.3.6.1.4.1.30065.3.12.1.1.1.5.100006101 = STRING: "No thresholds are defined"
                          Maybe you can change the threshold at the switch configuration.

                              And that was my thought exactly. I have reached out to the Arista switch admin to investigate. If you'd like, I will let you know the results. Again, thank you for your time and feedback.

                                  Hello burnsy29, Did you have any luck getting the switches to report correct Thresholds? We are running EOS 4.23.0F and are having the same problem. I am planning on upgrading to latest but I'm curious if that will fix it and if there is an alternate method as I will have to request downtime to upgrade. Thanks!

                                      So I cloned the Arista SNMP template and removed the Triggers for the voltages as they were being reported incorrectly. Applied that template to my 7050s and now I don't have to worry about the incorrect threshold values. Not the best but c'est la vie

                                          Here is an example of voltage from the host's latest data. Upsers
                                          Voltage (36 Items)
                                          CpucardPwrCon Rail1 12V: Voltage 2021-08-10 17:10:02 1.19 KV -1 V

                                          Example for temperature:
                                          Temperature (60 Items)
                                          Back-panel temp sensor: Temperature 2021-08-10 17:12:02 28.6 °C
                                          Back-panel temp sensor: Temperature status 2021-08-10 17:12:02 ok (1)
                                          CPU board temp sensor: Temperature 2021-08-10 17:12:02 31.5 °C +0.1 °C
                                          CPU board temp sensor: Temperature status 2021-08-10 17:12:02 ok (1)
                                          So it appears that there is no issue with the actual data, the issue lies in the trigger prototypes and the triggers themselves.

                                          Everything is very open with a clear description of the issues. It was truly informative. Your website is very helpful. Many thanks for sharing!
