Big IP F5 2000 Operating temperature

Good morning , i would like to ask a question regarding operational temperature of Big IP F5 2000 load balancer. At my work we have Nagios to monitor the health of BIG IP and the temperature threshold is 40 degrees as mentioned in the manual. Up to high temperature its fully functional cause i am have some alerts for 1 or 2 degress celsius and was wondering if possible to raise the threshold of the temperature to 45 degrees in order to avoid being spammed with false alerts. It doesnt work all the time close to 40 degrees just sometimes due to workload spikes and pass it ( highest temperature was 47 degrees )

    Hi Nick,

     

    Is your DataCentre/Comms room over 40 Degrees? I think it would be prudent to stick to manufacturers guidelines for heating alerts, rather than adjust them to stop alerts being raised.

     

    The other alternative is to configure Nagios to ignore anything below your threshold (If you feel that confident...)

      Dear Iain , No actually the data center is cooled efficiently ( has a stable 23 degrees Celsius ) but the location where the specific rack with the LB is in the position where it doesn't get optimal cooling ( also that rack happens to be full). So i was wondering since it spikes for a short period of time to 41 ,42 or 47 the highest with the fans not even working full speed at 20k ( mostly around 16k rpm ) maybe to increase the Nagios threshold to avoid that. As no expert in F5 thought better to ask first.

      Yes this is one of the solutions which will be implemented to solve this but i was wondering how the temperatures mentioned in the product info sheet are translated. Like 0- 40 Celsius is for the device internal temperature or for the ambient air temperature. And what are the warning temperatures for the device it self cause i need to set up my monitoring program not only to warn me about the temperature if exceeded more than 40 degrees but also to have a flag when it reaches "critical".
