I'm looking to monitor temperature on some various Cisco equipment (2821, 3750, 4948, 6509, etc). I've looked at the <a href="http://check_catalyst_temp.pl">check_catalyst_temp.pl</a> and check_env_stats.py plugins, which both look in .1.3.6.1.4.1.9.9.13.1. I see and understand the basic mechanisms of these checks.<div>
<br></div><div>What I don't understand is why both require warning and critical thresholds. From what I can tell, both walk ciscoEnvMonTemperatureStatusDescr, check <meta http-equiv="content-type" content="text/html; charset=utf-8"><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif; font-size: 13px; -webkit-border-horizontal-spacing: 1px; -webkit-border-vertical-spacing: 1px; ">ciscoEnvMonTemperatureState</span> (and alert accordingly) AND also check <span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif; font-size: 13px; -webkit-border-horizontal-spacing: 1px; -webkit-border-vertical-spacing: 1px; ">ciscoEnvMonTemperatureStatusValue to see if it's out of the warning and critical thresholds specified on the command line. I understand why one would want to be able to set custom thresholds (that would override "normal" and "warning" states). What I don't understand is why are they required? Is there a reason, or is it just an oversight? I don't have much experience monitoring network equipment, so I'm wondering if there's a reason for it.</span></div>
